Vertical distribution and swimming speed of pelagic fishes in winter and summer monitored in situ by acoustic target tracking
Creators: name: Jurvelius, J.

Publisher: name: Boreal Environment Research Publishing Board
Year: 2004

description: We studied the swimming speed and vertical distribution of fish under ice from March to April and in open water in August. Fish were surveyed with a downward facing stationary 120 kHz split beam echo-sounder in a boreal lake. A commercial trace tracking software was used to estimate the depth, speed and size of fish. Most fish in the study area were smelt (Osmerus eperlanus) and vendace (Coregonus albula). In March and April, fish were detected under the ice around the clock, whereas in August only a few fish were detected during daytime. Fish were typically detected between 12 and 19 m depth and they swam from 5 to 50 cm s–1 i.e. 0.5 to 3 body lengths s–1. The effect of sunrise and sunset on the under-ice swimming depth and speed became more marked with increasing day length. In summer, the effect on depth was not so evident. In March–April there was a shift towards day activity, which persisted in August. Changing illumination seemed to account for most variation in the swimming depth and speed of fish.

description: Herein, concentrating solar cells are modeled with two recombination active contacts and a recombination active light absorber in the framework of the one-diode model. The two contacts and the absorber contribute to a lumped series resistance and to a lumped recombination current. It is proven that varying the light concentration can be interpreted as iso-selectivity scaling of the cell's resistance and the cell's recombination. As a consequence of that, the optimal efficiency of a concentrator cell is found at maximum combined selectivity of the two contacts and the absorber. Herein, analytic formulas are derived that calculate the optimal contact areas and the optimal light concentration level for achieving an optimum efficiency. The resulting formulas express the efficiency in terms of the selectivities of each contact and the selectivity of the absorber. These equations are used to calculate the optimum contact area fractions and the optimum light concentration level for Si solar cells of various material qualities with screen-printed Al-doped contacts and n-type poly-Si contacts on oxide. The efficiency results of the novel analytic and a conventional numeric optimization agree to the expected level of accuracy.

description: We present an assessment of the exceedance probabilities of sea levels at Helsinki, on the coast of the Gulf of Finland in the Baltic Sea, based on an 850-year numerical sea-level simulation. The internal sea-level variations in the Baltic Sea are calculated with a two-dimensional hydrodynamic model, whereas the variations in the Baltic Sea water volume are evaluated using a statistical model based on the geostrophic wind speeds near Bornholm. The atmospheric data used for the sea-level simulation is taken from downscaled regional climate scenario simulations. The simulated sea-level extremes at Helsinki in the current climate are slightly smaller than the previous estimates which were based on measured data only. The extrapolation of simulated data gives an estimate of sea level 227 cm at Helsinki for the exceedance frequency of 10–4 events per year. The sum of the maxima of the model components during a short 30-year verification period indicates that sea level 225 cm is possible at Helsinki if all the components simultaneously attain their maxima.
“For My Old Kentucky Home, Far Away”: A Case for the Psycho-Sociological Dimension of Rural Brain Drain
Creators: name: Kapoor, Rishabh
Publisher: name: Stanford Digital Repository
Year: 2024
Subjects: College students' writings, education, rural outmigration, psychological and social factors, stereotypes

description: This essay won or received an honorable mention for The Boothe Prize for excellence in first-year writing. The Boothe Prize recognizes and rewards outstanding expository and argumentative writing by undergraduate students in first-year classes that satisfy the WR 1 requirement. In each award-winning essay, student writers demonstrate clarity of argument, excellent integration of research-based evidence, and compelling prose style.
This essay questions the common narrative used to explain rural outmigration—economic decline—which, the author argues, overshadows the psychological and social factors that also contribute to the outmigration of academically talented youth. The author then shows the ways the education system perpetuates these factors, primarily through the deficit thinking teachers hold about rural communities coupled with standardized curricula that may “dis-embed” students from their homes and effectively prime them to leave.
Shores in the city: opportunities, threats and challenges — viewpoints of citizens in Helsinki
Creators: name: Lodenius, M.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2004

description: The attitudes of citizens in Helsinki towards sea shores were investigated by means of three different surveys in the late summer of 2002. Survey data showed clear evidence that the shores are important to the citizens of Helsinki. People visited the shores often and participated in many different activities including general recreation, sunbathing, nature observation, swimming and physical exercise. Problems mentioned in the surveys were related on the other hand to the purity and tidiness of the water and the shores and on the other hand to the development plans of the growing city. Most people want to keep the shores in natural condition, but at the same time they also ask for services like litter bins, benches and toilets. People using boats would appreciate better garbage management, fire places and landing stages. There was some variation among different age groups and areas, but generally the citizens of Helsinki are quite unanimous in their opinions concerning the importance of shores and archipelago for physical and mental welfare.

description: The incorporation of nanopores into graphene nanostructures has been demonstrated as an efficient tool in tuning their band gaps and electronic structures. However, precisely embedding the uniform nanopores into graphene nanoribbons (GNRs) at the atomic level remains underdeveloped especially for in-solution synthesis due to the lack of efficient synthetic strategies. Herein we report the first case of solution-synthesized porous GNR (pGNR) with a fully conjugated backbone via the efficient Scholl reaction of tailor-made polyphenylene precursor (P1) bearing pre-installed hexagonal nanopores. The resultant pGNR features periodic subnanometer pores with a uniform diameter of 0.6 nm and an adjacent-pores-distance of 1.7 nm. To solidify our design strategy, two porous model compounds (1 a, 1 b) containing the same pore size as the shortcuts of pGNR, are successfully synthesized. The chemical structure and photophysical properties of pGNR are investigated by various spectroscopic analyses. Notably, the embedded periodic nanopores largely reduce the π-conjugation degree and alleviate the inter-ribbon π–π interactions, compared to the nonporous GNRs with similar widths, affording pGNR with a notably enlarged band gap and enhanced liquid-phase processability.

description: Simulations of the dark matter distribution throughout the Universe are essential in order to analyse data from cosmological surveys. $N$-body simulations are computationally expensive, and many cheaper alternatives (such as lognormal random fields) fail to reproduce accurate statistics of the smaller, non-linear scales. In this work, we present \textsc{Psi-GAN} (\textbf{P}ower-\textbf{s}pectrum-\textbf{i}nformed \textbf{G}enerative \textbf{A}dversarial \textbf{N}etwork), a machine learning model which takes a two-dimensional lognormal dark matter density field and transforms it into a more realistic field. We construct \textsc{Psi-GAN} so that it is continuously conditional, and can therefore generate realistic realisations of the dark matter density field across a range of cosmologies and redshifts in $z \in [0, 3]$. We train \textsc{Psi-GAN} as a generative adversarial network on $2\,000$ simulation boxes from the Quijote simulation suite. We use a novel critic architecture that utilises the power spectrum as the basis for discrimination between real and generated samples. \textsc{Psi-GAN} shows agreement with $N$-body simulations over a range of redshifts and cosmologies, consistently outperforming the lognormal approximation on all tests of non-linear structure, such as being able to reproduce both the power spectrum up to wavenumbers of $1~h~\mathrm{Mpc}^{-1}$, and the bispectra of target $N$-body simulations to within ${\sim}5$ per cent. Our improved ability to model non-linear structure should allow more robust constraints on cosmological parameters when used in techniques such as simulation-based inference.

description: Addressing the global challenges of climate change and biodiversity loss requires the widespread adoption of sustainable agricultural practices such as agrofor-estry. In many Sub-Saharan African countries, however, agroforestry adoption rates remain low among small-scale farmers, with insufficient knowledge about the benefits being a major barrier. To close this knowledge gap and increase farmers’ motivation to plant different tree species on their farms, this study applies a Role-playing game (RPG) as an awareness-raising tool. 72 small-scale farmers from Rwanda played the RPG and participated in pre-and post-game surveys. A comparison of responses before and after playing demonstrates that the RPG increased farmers’ knowledge and attitude toward most tree-related benefits. Moreover, playing the game significantly strengthened farmers’ motivation to plant more tree species on their farms. The findings were supported by debriefing results, confirming that RPGs are an effective tool to raise farmers’ awareness and motivation on sustainable land use management.

description: LiV$_2$O$_4$ is a member of the so-called $3d$ heavy fermion compounds, with effective electron mass exceeding 60 times the free electron mass, comparable to $4f$ heavy fermion compounds. The origin of the strong electron correlation in combination with its metallic character have been a subject of intense theoretical and experimental discussion, with Kondo-like physics and Mott-physics being suggested as its physical origin. Here we report state-of-the art \textit{ab initio} Density Functional Theory + dynamical mean-field theory calculations for LiV$_2$O$_4$ for the full three orbital V $t_\mathrm{2g}$ manifold, and present temperature-dependent spectral properties. We map out the phase diagram for a representative 3-orbital model system as a function of doping and interaction strength, which indicates that LiV$_2$O$_4$ is located between two orbital-selective Mott phases, giving rise to a robust strongly correlated Hund's metal behavior. At low temperature we find the emergence of a strongly renormalized sharp quasi-particle peak a few meV above the Fermi level of V $a_\mathrm{1g}$ character, in agreement with experimental reports.

description: In global analyses of nuclear parton distribution functions (nPDFs), neutrino deep-inelastic scattering (DIS) data have been argued to exhibit tensions with the data from charged-lepton DIS. Using the nCTEQ framework, we investigate these possible tensions both internally and with the data sets used in our recent nPDF analysis nCTEQ15WZSIH. We take into account nuclear effects in the calculation of the deuteron structure function $F_2^D$ using the CJ15 analysis. The resulting nPDF fit, nCTEQ15WZSIHdeut, serves as the basis for our comparison with inclusive neutrino DIS and charm dimuon production data. Using $χ^2$ hypothesis testing, we confirm evidence of tensions with these data and study the impact of the proton PDF baseline as well as the treatment of data correlation and normalization uncertainties. We identify the experimental data and kinematic regions that generate the tensions and present several possible approaches how a consistent global analysis with neutrino data can be performed. We show that the tension can be relieved using a kinematic cut at low $x$ ($x>0.1$) and also investigate a possibility of managing the tensions by using uncorrelated systematic errors. Finally, we present a different approach identifying a subset of neutrino data which leads to a consistent global analysis without any additional cuts. Understanding these tensions between the neutrino and charged-lepton DIS data is important not only for a better flavor separation in global analyses of nuclear and proton PDFs, but also for neutrino physics and for searches for physics beyond the Standard Model.

description: Determination of alkali elements is important to Earth scientists, yet suitable and reliable microanalytical reference materials are lacking. This paper proposes a new albite reference material and evaluates the potential for future K-feldspar reference materials. The proposed Piz Beverin albite reference material from Switzerland yields a homogeneous composition at the centimetre- to micrometre-scale for Si, Al and Na with < 2000 μg g-1 total trace elements (mostly heterogeneously distributed Ca, K and Sr). EPMA and LA-ICP-MS measurements confirm a composition of 99.5(2)% albite component, which is supported further by bulk XRF measurements. A round robin evaluation involving nine independent EPMA laboratories confirms its composition and homogeneity for Si, Al and Na. In addition, a set of five distinct clear K-feldspar samples was evaluated as possible reference materials. The first two crystals of adular and orthoclase yield unacceptable inhomogeneities with > 2% relative local variations of Na, K and Ba contents. The three other investigated sets of K-feldspar crystals are yellow sanidine crystals from Itrongay (Madagascar). Despite distinct compositions, EPMA confirms they are each homogeneous at the centimetre to micrometre scale for Si, Al and K and have no apparent inclusions; further investigation to find larger amounts of these materials is therefore justified.

description: We adopted a multiscale approach to examine the spatial relations between stream fish, macroinvertebrate prey, and habitat characteristics in a boreal stream. The study site was divided into 279 cells, and abundances of brown trout and Arctic bullhead were quantified at each cell. Depth, water velocity, substrate size and aquatic vegetation were measured, and benthic samples collected, at each quadrat. Shaded contour plots showing the spatial distribution of selected variables within the sample space were produced and fish distributions were superimposed on these plots. High-density patches of trout and bullhead were in separate sections of the riffle, and bullhead were closely associated with their benthic prey, especially semisessile macroinvertebrates. Semivariograms were produced for two variables, water depth and density of semi-sessile invertebrates. There was spatial dependence, especially in the density data, at lags shorter than 2 metres. Kriging was then used to create maps displaying the spatial patterns of the variables within the sample space. We believe this kind of multi-scale sampling strategy combined with standard geostatistical tools and statistical modeling will prove valuable in the study of aquatic consumer-resource interactions.

description: We used stable isotopes of sulfur (δ34S) and carbon (δ13C) to distinguish resident and migratory pikeperch (Sander lucioperca) among individuals captured from a coastal freshwater lagoon (Curonian Lagoon) and adjacent Baltic Sea waters. We found that non-migratory pikeperch collected from the lagoon had negative δ34S ratios (–1.84‰ to –0.17‰), whereas migrating individuals exhibited higher and more variable δ34S values (4.4‰ to 18.5‰). Our findings suggest that S isotopes may be a valuable tool for assessing migratory habits in the brackish waters. We also compared cyanotoxin concentrations among the resident individuals of Curonian Lagoon and the migratory individuals in or returning from the Baltic Sea. No difference in toxin levels was observed among the resident and migratory pikeperch, although toxin concentrations were frequently close to or exceeded the recommended concentrations for safe long-term human consumption.

Forest fire histories and tree age structures in Värriö and Maltio Strict Nature Reserves, northern Finland
Creators: name: Aakala, T.

Year: 2018

description: Wildfires virtually disappeared from the Fennoscandian forests in the 20th century, but have left persistent legacies in forest structure. Here, I reconstructed past fires in three northern boreal landscapes (each 2 km x 2 km) from fire scars, and described the fire regime for the past 300 years. The average fire cycles (1700–1999) were 72 and 156 years in Pinus sylvestris-dominated landscapes, and 579 years in a Picea abies-dominated landscape. At the site level, the number of fires was clearly related to soil hydraulic properties. Age structures from 1800 live and dead trees showed strong cohorts associated with large fires in two of the landscapes. Although tree growth and regeneration in sub-arctic regions are considered highly climate-sensitive, fires have been a major driver of forest dynamics in these areas. Continued absence of fires will lead to considerable changes in the forest structure and species composition in the future.

description: Tool grinding is a fundamental process step when manufacturing cylindrical cemented carbide tools. A deeper understanding of the relationship between heat generation, heat transfer and fluid dynamics is essential to optimize the application of cooling lubrication. Due to the porous structure of the grinding tool as well as the rough surfaces of tool and workpiece, this inherently leads to multiscale problems. In this paper, an approach for modeling the heat transfer between the grinding tool, the workpiece and coolant on the microscale and mesoscale is introduced, including the effective influence of the porous structure. As a basis for the simulations, experimental investigations are conducted using individual abrasive grains. A linear relationship between the single grain chip cross section and the tangential force is established with an average RMSE of 1.421 N, allowing the total heat flux to be calculated. The results are then transferred to continuous and discontinuous 2D multiscale fluid dynamic simulations in order to predict heat generation and to potentially optimize the cooling lubrication in grinding processes.

description: The eikonal correspondence between the quasi-normal modes (QNMs) of asymptotically flat static spherically symmetric black holes and the properties of unstable null circular geodesics is studied in the case of higher dimensional Lovelock black holes (BHs). It is known that such correspondence does not generically hold for gravitational QNMs associated with BHs in Lovelock theories. In the present work, we revisit this correspondence and establish the relationship between the eikonal QNMs and the causal properties of the gravitational field equations in Lovelock theories of gravity.

Year: 2002

description: The degree of radiocontamination in fish is usually analysed to estimate doses to fish consumers, for which the radionuclide contents in the edible parts of fish are needed. Recently increasing attention has been focused on radiation protection in plants and animals. To estimate the effects of radiation on fish, the distribution of radionuclides in various organs and radiosensitivity of the organs must be known. A step towards this was taken when the Radiation and Nuclear Safety Authority (STUK) of Finland determined the distribution of 137Cs and 90Sr in muscle tissue, skin + fins, and bones in perch samples, in muscle and bones or in muscle, skin + fins, and bones in pike samples and in muscle + skin + fins and bones in vendace samples. Accumulation of 137Cs in fish liver, spawn and sperm was also studied and compared with respective values in the edible parts. The importance of skin and fins was evident as a source of 90Sr to fish. Fish sperm showed somewhat higher activity concentrations of 137Cs than muscle.

Differential diagnosis.
This species is not similar to any of its congeners. The shell shape (conical) and apertural dentition (one barrier on the parietal side) strongly resembles some Anauchen species (e. g., A. angthongensis) but the surface is granulated as in H. hungerfordianum and all whorls are keeled. See also under H. khmerianum.
Distribution.
Apart from the type locality, this species is also known from one more nearby locality.
Remarks.
Even though this species has high morphological similarities to some Anauchen species (e. g., A. angthongensis), the shell surface sculpture is characteristically granulated (as in H. hungerfordianum) which is the reason it is transferred to this genus.

description: In the transition to more sustainable regional economies, the widespread adoption of green technologies is crucial. However, little is known about the geography of green technology adoption and the relationship between regional demand and supply of green technologies. In this paper, we shed light on the (regional) factors explaining whether innovation adopters use green technologies that have been developed locally or green technologies that have been developed in other places. We analyze a unique data set of 8825 licensing agreements for Chinese patents in green technologies, which we use as an indicator to measure innovation diffusion. Our results suggest that the regional context plays a key role in predicting whether innovation adopters use local or non-local green technologies. We show, among other things, that the use of locally developed green technologies is more likely in regions characterized by green technology specializations and high innovation capacity than in less innovative regions.

description: Records of the time-varying temperature profile at flight relevant operating conditions are acquired at the exit of a combustion chamber fitted with a staged, lean-burn fuel injector using high-speed laser induced fluorescence (LIF) at a sample rate of 10 kHz. Temperatures are estimated from the concentration dependent fluorescence of the hydroxyl (OH) radical under the assumption of local equilibrium. Beyond the time-series analysis, the acquired data is correlated with simultaneously acquired OH chemiluminescence sampled in the primary zone near the fuel injector. These analyses reveal a strong influence from the precessing vortex core, originating in the primary zone, on oscillations in the temperature profiles measured at the exit of the combustor.

description: The dependence of sea level on past and future climatological conditions is investigated in nearly tideless semi-enclosed sub-basins of the Baltic Sea using trend analysis of the tide gauge data for the period of 1924–2003 and hydrodynamic modelling. The results suggest that in addition to the effect of eustatic rise in mean sea level and its partial compensation by isostatic land uplift, the water level has risen by up to 6 cm near the Estonian coast during the last fifty years, probably due to changes in wind climate. The sea-level increase was concentrated in the period from November to March. It is in good correlation with increasing trends in local storminess and in higher intensity of westerlies, as described by AO and NAO indices. For the future sea level, a set of sensitivity and scenario runs considering possible future changes in wind climate was performed using a 2D hydrodynamic model with a 1-km grid-step. The scenario runs show that if the intensity of westerlies continues to grow (with less than 20% annual mean wind speed increase) the local annual mean sea level rise up to 5–6 cm can occur in some windward bays of the Gulf of Riga. The rise can be up to 9–11 cm in winter months, while in summer the sea level rise is unlikely. Also, increase in variability and extremes can be expected.

description: In nowadays production, fluctuations in demand, shortening product life-cycles, and highly configurable products require an adaptive and robust control approach to maintain competitiveness. This approach must not only optimise desired production objectives but also cope with unforeseen machine failures, rush orders, and changes in short-term demand. Previous control approaches were often implemented using a single operations layer and a standalone deep learning approach, which may not adequately address the complex organisational demands of modern manufacturing systems. To address this challenge, we propose a hyper-heuristics control model within a semi-heterarchical production system, in which multiple manufacturing and distribution agents are spread across pre-defined modules. The agents employ a deep reinforcement learning algorithm to learn a policy for selecting low-level heuristics in a situation-specific manner, thereby leveraging system performance and adaptability. We tested our approach in simulation and transferred it to a hybrid production environment. By that, we were able to demonstrate its multi-objective optimisation capabilities compared to conventional approaches in terms of mean throughput time, tardiness, and processing of prioritised orders in a multi-layered production system. The modular design is promising in reducing the overall system complexity and facilitates a quick and seamless integration into other scenarios.

description: Long-term trends of ambient gaseous pollutants and particulate matter in Helsinki metropolitan area were analyzed from 1994 to 2019. Measurement data from ten monitoring stations located in different types of urban environments including traffic, urban background, rural background, and suburban area were included in this study. We analyzed gas-phase air pollutants, such as NO, NO2, NOx, O3, SO2 and CO; and for aerosol pollutants, we explored mass concentrations for particles smaller than 10 µm and 2.5 µm in diameter (PM10 and PM2.5, respectively ). In order to quantify trends in the data, we deployed a non-parametric Mann-Kendall test and Theil-Sen method. The results were compared with the regional emissions trends and changes in meteorological conditions. Our analysis indicates that SO2 and CO in all stations have decreased to values corresponding to their regional background concentration levels and their role as urban air pollutants have diminished. Our results from the Helsinki Metropolitan area during the last 25 years show that the air quality improved and all the air pollutant concentrations show a decreasing trend, except ozone. Based on our analysis of the Air Quality Index (AQI) at traffic and urban background environments, NO2 concentration, which have typically represented the health effects resulting from vehicular traffic, is rapidly decreasing also in traffic environments. The current AQI standard therefore lacks clarity on the potential health risks from other air pollutants emitted from traffic exhaust. In addition, the air quality indicators currently considered in the AQI do not represent well enough residential wood burning and the possible health outcomes from its exposure. We suggest that the current AQI should be revised in a way that new air quality parameters would be considered, which would better represent the health effects resulting from these local combustion sources.

description: The probability of a new ultrafine particle formation as well as the spatial sources of the nucleation, Aitken and accumulation modes of particles measured in Hyytiälä, southern Finland, were investigated using air mass history analysis. The studied period covered the years 1997–2003. We estimated the probability of a new ultrafine particle formation for nine sub-areas inside a domain limited by 50°N–80°N in latitude and 30°W–60°E in longitude. For all the seasons North Atlantic and arctic regions dominated as an origin of air masses that accompany nucleation events. The probability of nucleation events in Hyytiälä reached its maximum in spring and summer with north and north-west air masses transfer directions. The highest concentration of nucleation mode particles was observed in arctic and polar air masses, whereas the highest concentration of accumulation mode particles was observed during intrusions of continental air masses.

description: Two bog ecosystems were compared by their ability to release CH4 into the atmosphere during the warm season, and the influence of environmental factors (water table level and peat temperature) on CH4 fluxes from the bog surface was studied. The studied bog ecosystems belong to the ombrotrophic bogs of the taiga zone of Western Siberia, but they differ significantly in vegetation cover, structure of peat deposits, hydrological conditions, and temperature of peat layers. Methane fluxes were measured using the close static chamber method. The results show that CH4 emissions vary from site to site depending on the local hydrological regime and the type of vegetation cover. The mean±standard deviations of the CH4 emission flux from the open and forested bogs were found to be 2.66±4.58 mg m–2 h–1 and 0.57±0.69 mg m–2 h–1, respectively. The calculated total CH4 flux shows that the amount of CH4 released from open bog is on average 4.7× higher than from forested bog, despite the fact that the former cover an area 1.5× smaller than that covered by the latter. The seasonal dynamics of CH4 fluxes in both bog ecosystems are characterized by a July maximum and are closely related to peat temperature, but are not connected with the water level. In open bogs, the average daily CH4 emission variability was found to be 50% due to the influence of peat temperature at the depth of 10 cm, while in forested bogs it was found to be 39% due to peat temperature at the depth of 40 cm. The research results indicate a direct and very important link between the vegetation species composition and the hydrological regime of bog ecosystems in the estimates of the CH4 flux from bog ecosystems in the region. This link causes high variability of the CH4 fluxes at a small scale, which is often not accounted for when assessing CH4 budgets of bogs and modelling responses of bog ecosystems to climate change.

description: Atmospheric deposition of nitrogen (N) to boreal and taiga forests of Saskatchewan, Canada, is currently low, but there is concern over terrestrial eutrophication due to potential increases in deposition associated with industrial activities. Critical loads of nutrient N (CLnutN) were determined for five upland forest ecoregions according to the Simple Mass Balance (SMB) model using an uncertainty-based approach. Median ecoregion CLnutN ranged from 88 to 123 molc ha–1 yr–1 (1.2–1.8 kg N ha–1 yr–1), with higher CLnutN in the south. Median CLnutN for a small number of sites in the southernmost ecoregion were exceeded under both fire and harvest disturbance regimes, according to current N deposition. During the 21st century, median CLnutN were predicted to increase by more than 20% in response to climate driven increases in runoff and temperature. Current atmospheric deposition levels in the region are uncertain, and there is an ongoing need to monitor deposition and exceedance risk.

description: The combined use of data from different sources can be critical in emergencies, where accurate models are needed to make real-time decisions, but high-fidelity representations and detailed information are simply unavailable. This study presents a data assimilation framework based on an ensemble Kalman filter that sequentially exploits and improves an advection-diffusion model in a case study concerning an airborne contaminant dispersion problem over a complex two-dimensional domain. An autonomous aerial drone is used to sequentially observe the actual contaminant concentration in a small fraction of the domain, orders of magnitude smaller than the total domain area. Such observations are synchronized with the data assimilation framework, iteratively adjusting the simulation. The path of the drone is sequentially optimized by balancing exploration and exploitation according to the available knowledge at each decision time. Starting from an erroneous initial model based on approximated assumptions that represent the limited initial knowledge available during emergency scenarios, results show how the proposed framework sequentially improves its belief about the dispersion dynamics, thus providing a reliable contaminant concentration map.
The effect of load reductions on algal biomass in the eastern Gulf of Finland estimated by the FINNALGA model

description: Eutrophication and algal blooms are major environmental problems in the Gulf of Finland. One possible way to approach the problem is mathematical modelling. If the most important processes are successfully modelled, it is possible to calculate the effects of human activity. The application of an ecological model to the eastern Gulf of Finland is presented here. The algal model used is coupled with a 3-dimensional hydrological one. The application year used was 1994 and the validation year 1995. The load reductions used are based on the recommendation of HELCOM or a more realistic assessment. Results received indicate, that clear effects can be observed even within a short period. According to our model the reduction of phosphorus load is important near river entrances, while for the open eastern Gulf of Finland nitrogen is more important.
