expresión editorial de l’Architecture Vivante: de los sistemas persuasivos a la edición crítica
Authors: Álvarez Benítez Paula V.
Published: March 2022

L’Architecture Vivante fue una revista francesa que divulgó tempranamente la producción de las vanguardias arquitectónicas de comienzos del siglo XX, convertida hoy en un relevante documento histórico-cultural. En su expresión editorial convergen, no sin conflicto, distintas variables semánticas: los significados que emanan de las decisiones editoriales de Jean Badovici, los implícitos en los marcos semánticos característicos del diseño editorial de Ediciones Morancé y los aportados por las obras publicadas. Siguiendo la metodología de los estudios culturales, situaremos estas variables en un contexto cultural amplio, leyéndolas en polémica con las políticas de reorganización de los procesos productivos en masa y la integración del marketing en el diseño para adaptar las producciones culturales a una situación de consumo. Se mostrará que, si bien L’Architecture Vivante se alinea en cierta medida con los constructos discursivos y codificaciones editoriales que trataron de fijar y contener el significado de aquellas búsquedas, también los desafía, conservando aún hoy una valencia crítica.

La ciudad de Busan experimenta a finales del siglo XIX, una fuerte ruptura con su tradición mediante una modernización forzada (tabula rasa), tanto en el cambio espacial (tabula real) como en la comprensión del mismo y en su representación cartográfica (tabula virtual). Este texto interpreta el proceso de eliminación del espacio tradicional a través de cartografí­a, la herramienta para producir y dominar espacios modernos. Analiza además la cartografí­a tradicional para compararla con la que la reemplaza. Y finalmente redibuja el paisaje borrado y olvidado a través de la misma herramienta, la cartografí­a (tabula plena).

As macrófitas aquáticas apresentam grande importância ecológica, principalmente por serem os principais produtores primários de matéria orgânica, fator de extrema importância para a manutenção das diversas formas de vida. Porém, apesar de sua importância estar bem enfatizada na literatura brasileira, país onde existem os maiores ecossistemas aquáticos continentais, as pesquisas sobre essas comunidades ainda são escassas. Assim, esse estudo objetiva realizar o levantamento das macrófitas aquáticas registradas no Herbário Professor Vasconcelos Sobrinho – UFRPE - visando identificar as espécies estabelecidas no interior ou nas margens de lagos, rios, riachos, várzeas e açudes. Foi listado um total de 31 famílias, 88 gêneros e 119 espécies; a família Cyperaceae apresentou maior número de gêneros e espécies. O gênero Eleocharis foi o mais abundante. Foi observado que 44,29% das espécies foram coletadas no Litoral, 14,76% na Zona da Mata, 8,05 % no Sertão e 4,69 % no Agreste. O número mais elevado de coletas na região litorânea pode estar relacionado ao fato da maior facilidade de acesso aos locais de coleta e ao interesse dos pesquisadores em áreas de reservatórios existentes nessas regiões.

Abstract. We present a method for estimating fossil fuel methane emissions using observations of methane and ethane, accounting for uncertainty in their
emission ratio. The ethane:methane emission ratio is incorporated as a spatially and temporally variable parameter in a Bayesian
model, with its own prior distribution and uncertainty. We find that using an emission ratio distribution mitigates bias from using a fixed,
potentially incorrect emission ratio and that uncertainty in this ratio is propagated into posterior estimates of emissions. A synthetic data test
is used to show the impact of assuming an incorrect ethane:methane emission ratio and demonstrate how our variable parameter model
can better quantify overall uncertainty. We also use this method to estimate UK methane emissions from high-frequency observations of methane and
ethane from the UK Deriving Emissions linked to Climate Change (DECC) network. Using the joint methane–ethane inverse model, we estimate annual
mean UK methane emissions of approximately 0.27 (95 % uncertainty interval 0.26–0.29) Tg yr−1 from fossil fuel sources and 2.06 (1.99–2.15) Tg yr−1 from non-fossil fuel sources, during the period 2015–2019. Uncertainties in UK fossil fuel emissions estimates are
reduced on average by 15 % and up to 35 % when incorporating ethane into the inverse model, in comparison to results from the methane-only
inversion.
Neoproterozoic geodynamics of South China and implications on the Rodinia configuration: the Kunyang Group revisited

Published: March 2022

The late Mesoproterozoic to early Neoproterozoic strata in the Yangtze Block hold a key position in deciphering the tectonic evolution of the South China Block and implicate upon the reconstruction of the Rodinia supercontinent. The sedimentological, geochronologic, and geochemical data on the Kunyang Group, southwestern Yangtze Block, were evaluated for a better understanding of the regional geodynamics and refinement in its paleoposition in the Rodinia supercontinent. Our findings constrain the deposition of the Kunyang Group sediments occurring during 1152 Ma and 1000 Ma, under a stable environment with alternating neritic and littoral facies sedimentation. In contrast, deposition of the Meidang Formation, traditionally thought to represent the upper part of the Kunyang Group, continued up to 866 Ma in an active setting at varying basin depths and hydrodynamic conditions. Moderate to high SiO2 contents (57.7-95.4 wt%), highly variable K2O/Na2O ratios (0.01-55.8), and critical trace element abundances (Zr: 57.6-578 ppm, Th: 1.95-28.3 ppm, Sc: 0.75-24.3 ppm), detrital zircon age distribution, sedimentological characteristics, and bimodal magmatism cumulatively underline a transition from continental rift to passive continental margin setting, followed by an active continental marginsetting. The onset of oceanic subduction below the SW-NW margin of the Yangtze Block caused a hiatus in sedimentation, marked by an unconformity between the Kunyang Group and Meidang Formation.

Paleocurrent data, zircon U-Pb ages, and Lu-Hf isotopic characteristics indicate that the Kunyang Group received detritus from some interior sources and exotic terranes, such as the Gawler Craton in Australia, the Transantarctic Mountains in East Antarctica, and the Ongole domain in the Eastern Dharwar Craton of India. The Yangtze Block was likely located to the west of Australia and East Antarctica and north of India in the Rodinia supercontinent. Paleocurrent data also confirm an external location for the Yangtze Block in the Rodinia paleogeographic configuration.
Physical processes driving intensification of future precipitation in the mid- to high latitudes: an example from Norway
Authors: Poujol Basile , Sobolowski Stefan , Mooney Priscilla
Published: March 2022

Precipitation is changing as the climate warms. Downpours can potentially become more intense, frequent, and of longer duration due to the increased water holding capacity of the atmosphere and other (thermo)dynamical responses. However, the exact nature of the precipitation response and its characteristics are still not well understood due to the complex nature of the physical processes underlying the formation of clouds and precipitation. 

In this study, present and future Norwegian climate are simulated at convection-permitting scales with a regional climate model. Hourly precipitation is separated into three categories (convective, stratiform, and orographically enhanced stratiform). This is achieved using a physically-based algorithm that is tested over different mountainous areas. 

We investigate changes in the frequency, intensity and duration of precipitation events for each category, delivering a more nuanced insight into the precipitation response to a changing climate. Results show a significant intensification of autumn precipitation and more frequent convective precipitation. The precipitation response in autumn and spring deviates from the idealised thermodynamic response, partly owing to changes in cloud microphysics. These results show that changes in the precipitation distribution are affected in complex ways by the local climatology, terrain, seasonality and cloud processes. Given the societal impacts of intense rainfall, there is an imperative to further understand these complexities, thus enabling greater societal resilience to climate change.
Global urban drought risk

Published: March 2022

This study aims to assess current and future global hydrological drought risk for 263 cities around the globe. Preliminary results among 98 cities show that around 73% of them will likely experience an increase in drought costs in the coming decades. Furthermore, they show that current drought costs are on average between USD 8,000 – 32,000 per 1000 citizens per year, which could increase to approximately USD 9,000 – 40,000 by 2050.  Not many studies have focussed on drought risk at the global scale before, and even fewer explicitly consider cities. However, drought events can have profound impacts on urban areas, as is illustrated by past events like those in Cape Town (2015-2018) and São Paolo (2014-2015). Although research has been done on such specific events, their individual results are often difficult to compare. Therefore, we try to enable that comparison by performing a global urban drought risk assessment, which reveals hotspots of urban drought risk and potentially even puts drought risk on the agenda for cities that are not yet aware of the risks they face. In our approach, we focus on hydrological drought, which is the drought type that most directly affects urban water resources. We link surface-water availability with urban-water withdrawals in the water-source locations of the cities, while taking into account water stress and environmental flow requirements. The hazard is dynamic in time, and future scenarios are based on a selection of RCPs. Exposure is represented as the total population in each city, and evolves over time as well, based on several SSPs. From the hazard and exposure, we use global estimates of freshwater replacement costs to calculate drought cost ranges for each city. We also qualitatively add vulnerability by overlaying the cost ranges with several vulnerability indicators to provide bivariate maps of risk for each city. In addition, attempts are made to verify the results with city practitioners as well as to identify several transformative adaptation options for cities.
Estimation of organic positive artefacts on Quartz filters and volatilization loss from Teflon filters at a COALESCE network site - Bhopal, India
Authors: Bhardwaj Ankur , Sunder Raman Ramya
Published: March 2022

Measurement of ambient particulate organic carbon (OC) collected on quartz filters is susceptible to net positive artefacts (overestimation of particulate OC due to adsorption of volatile and semi-volatile organic compounds) while that collected on Teflon filters is susceptible to net negative artefacts (loss of particle OC due to volatilization). In this study, QbQ (Quartz behind Quartz) filter configuration was used for estimating positive artefact, while, QbT (Quartz behind Teflon) filters in conjunction with the QbQ were used to estimate OC volatilization from Teflon filters over a two-year (2019 and 2020) period in Bhopal, one of the eleven COALESCE (Carbonaceous Aerosol Emissions, Source Apportionment, and Climate Impacts) network sites in India. OC and EC measurements by thermal-optical carbon analyses on 748 samples (349 bare quartz (Q), 349 QbQ, and 50 QbT; 24 hours time-integrated) were used in this study. The results showed that the average adsorbed gaseous OC contribution to total OC measured on quartz filters was 17 % (0.9 µg m-3) and 11 % (0.6 µg m-3) during 2019 and 2020, respectively. Organics volatilization loss from Teflon filters as a fraction of measured PM2.5 mass were estimated by applying organic matter (OM)/OC ratios ranging between 1.7 and 2.0 to the OC measured on QbT filters. The annual mean volatilized OC  that was likely re-captured by bare quartz but lost from Teflon filters were 27 % (1.6 µg m-3) and 21 % (1.1 µg m-3) of the total OC measured during 2019 and 2020, respectively. Also, the average PM2.5 lost due to OM volatilization was 8 % (± 4 %) and 6 % (± 5 %) during 2019 and 2020, respectively. Our work shows that organic volatilization artefacts from Teflon filters are likely to be substantial at most locations in India, where temperatures exceed 30 °C for most of the year, and should be accounted for in assessments of gravimetrically determined PM2.5 mass closure using chemical species measured on multiple filter substrates.
Eddy saturation in a reduced two-level model of the atmosphere
Authors: Kobras Melanie , Ambaum Maarten H. P. , Lucarini Valerio
Published: March 2022

Eddy saturation describes the nonlinear mechanism in geophysical flows whereby, when average conditions are considered, direct forcing of the zonal flow increases the eddy kinetic energy, while the energy associated with the zonal flow does not increase. We present a minimal baroclinic model that exhibits complete eddy saturation. Starting from Phillips’ classical quasi-geostrophic two-level model on the beta channel of the mid-latitudes, we derive a reduced order model comprising of six ordinary differential equations including parameterised eddies. This model features two physically realisable steady state solutions, one a purely zonal flow and one where, additionally, finite eddy motions are present. As the baroclinic forcing in the form of diabatic heating is increased, the zonal solution loses stability and the eddy solution becomes attracting. After this bifurcation, the zonal components of the solution are independent of the baroclinic forcing, and the excess of heat in the low latitudes is efficiently transported northwards by finite eddies, in the spirit of baroclinic adjustment.
Analyzing the effects of clay content on ammonium migration in soil using single- and dual-porosity models
Authors: Agarwal Pooja , Sharma Pramod Kumar
Published: March 2022

The rapid growth of agricultural and industrial sectors has led to inappropriate disposal of pesticides and effluents thereby causing massive ammonium contamination of soil and groundwater resources. Contaminant transport is governed by the adsorption mechanism, which varies as the contaminant migrates through different types of soils. It is important to determine the model that best defines the adsorption mechanism of ammonium ions and the factors influencing it to predict and mitigate their contamination. This work focuses on studying the effects of clay content present in the soil on the adsorption and eventually on the retardation of ammonium ions transport through soil media using single- and dual-porosity models. The movement of ammonium ions was analyzed for three soil types with different clay proportions, by column and batch experiments. The experimental results were verified by simulating ammonium migration by numerical modeling using HYDRUS-2D software. It was observed that the ammonium ions adsorption increases with the increase in the clay content of the soil. Therefore, greater content of clay in the soil enhances the attenuation of ammonium migration in the soil media. Further, the dual-porosity model was found to be a significant factor in analyzing ammonium migration where the presence of an immobile phase in the system contributes to the transport and sorption mechanism of ammonium ions into the porous medium.

Keywords: Clay content, Ammonium ions, Single-porosity, Dual-porosity, Adsorption.

The Lake Hazar (Elazığ) is situated as an inter-mountain basin located on the East Anatolian Fault Zone (EAFZ) which is a major continental left-lateral strike-slip fault in Eastern Turkey. Since most of the major cities in the eastern part of Turkey with high populations are located along or near the EAFZ; studies focused on earthquake risk in the near-future have a significant importance of carrying in terms of socio-economic conditions. Relevant with massive earthquakes during different geologic periods due to local and regional tectonic conditions; occurred earthquakes are measured between 6.7-7.8 Mw in Lake Hazar during the last 50 years.

Therefore, Lake Hazar is considered to be archive as receiving most of the past earthquake records that are considered to be deposited as turbidites along the lake floor. For this reason, this study aims to investigate the earthquake-related turbidites (seismo-turbidites) in Lake Hazar and special interest on their sedimentological parameters. For this purpose; seven sediment cores retrieved from Lake Hazar have been examined by using multi-parameters, including mainly sedimentologic analyses together with physical and geochemical imprints. Grain size parameters of the seismoturbidites such as mean, mode, and median together with sorting and skewness reveal depositional processes during the turbidite deposition along the lake floor. According to lithologic and grain size parameters; deciphered distinct facies variations of seismoturbidites, each of them was indicated various sedimentologic processes related to different depositional dynamics. The geochemical analyses of the seismoturbidite allow us to define the deepwater condition during and after its deposition and the source of the transported sediments.

The formation of laminated seismoturbidites is characterized by the finest-grain size that was presumably formed by suspended deposition under a strong seiche effect in deep parts of the lake. The coarser seismoturbidites represent massive and graded facies that are mainly deposited by traction carpet along the lake slopes as a result of slumps triggered by the earthquakes. The high fluctuation in grain sizes of the coarser seismoturbidites also indicates the existence of seiche effect during/or after the earthquakes that may have resulted in strong grain segregation of the transported sediments from slope to the basin of the lake.

An accurate simulation global thermospheric neutral density (TND) on various altitudes is important for geodetic and space weather applications. In addition, this is essential for designing the low-Earth-orbit (LEO) missions, predict their missions’ lifetime and performing a reliable attitude control. Although empirical and physics-based models typically simulate TND variations, the quality of these models is limited due to various structural simplifications and the uncertainty of inputs. Here, we present an ensemble Kalman filter (EnKF)-based calibration and data assimilation (C/DA) technique that updates the model's states and simultaneously calibrates its key parameters. The proposed approach provides the opportunity to improve the now-cast and forecast skills of the NRLMISISE-00 and NRMSIS-2.0 models through re-calibrating the model’s key parameters including those controlling the influence of solar radiation and geomagnetic activity as well as those related to the calculation of exospheric temperature.

In this research, TND estimates from on-board accelerometer measurements of GRACE, GRACE-FO and Swarm are ingested as observations into the NRLMSISE-00 and NRLMSIS-2.0 models based on the C/DA. The newly calibrated model, called here ‘C/DA-NRLMSISE’, is then used to simulate global maps of TND as well as individual neutral mass densities covering the altitudes of 300-600 km. Various investigations are performed to test the temporal and vertical consistency of the TND outputs from C/DA-NRLMSISE.
Maintaining functional connectivity is essential for reducing negative effects of climate change on endangered species

Maintaining riverine habitat connectivity for important ecological processes like fish reproduction is essential for conserving endangered migratory species in regulated river. The unique reproductive behavior of migratory fish, which has a potential effect on habitat connectivity assessment, is the key for the success of population restoration in a changing climate conditions. However, existing analytic connectivity models mostly focus on broad-scale terrestrial studies tested with landscape features and large-scale riverine hydrological cases, they are not able to describe aquatic micro-habitat connectivity and cannot incorporate effects of multiple pathways linking spawning function areas with altered hydrological conditions. Here, we developed an ecological functional connectivity model that overcame these obstacles by borrowing from electrical circuit theory and highlighting functional attributes of habitat patches. It was the first time for circuit theory to apply in water ecosystem environment for habitat protection and population rebuilding. In this model, a function path tree restricted to patch connectivity constraints was first proposed for micro-habitat connectivity index. The model greatly improves aquatic habitat suitability predictions because it incorporates patch function attributes to account for habitat status and simultaneously integrates all possible pathways connecting spawning function areas for a more reliable connectivity assessment. When applied to data from Chinese sturgeon (a well-known endangered anadromous fish) in the Yangtze River, our model outperformed conventional aquatic habitat models, revealing that the low functional connectivity in spawning function areas, especially between dispersal area and incubation area, was a limiting factor for Chinese sturgeon reproduction. Results also demonstrated that contributions of global warming on increasing stream temperature intensified spawning habitat fragmentation, which would further hampered fish breeding activities. The proposed model is transferrable to fish species with different life histories, and holds much promise in habitat restoration, river management and conservation planning to reduce future ecological impacts of climate change.
Last Glacial Maximum to present day precipitation changes from speleothem growth rates and in climate simulations

To reliably predict future changes, it is crucial to understand the response of the climate system to past changes in radiative forcing, which are investigated using climate models as well as information extracted from paleoclimate archives such as speleothems. Hydrological changes in past, present, and future are, however, far less understood and more uncertain than changes in temperature.

Speleothems are terrestrial archives in the low to mid latitudes. Their growth rate changes are hypothesized to reflect local changes in precipitation amount, albeit the response may be non-linear and subject to karst specific processes. Full coverage of glacial-interglacial cycles and high precision dating through U/Th measurements makes them a suitable archive to assess and constrain state-dependent precipitation changes. However, speleothem inherent features, such as growth hiatuses or large and abrupt changes in growth rates, are a challenge for current age-depth modelling methods.

Here, we compare modelled precipitation amount from the Paleoclimate Modeling Intercomparison Project (PMIP), in particular time slices of the Last Glacial Maximum (around 21.000 years before present) and the Mid-Holocene (around 6.000 years before present) to growth rate changes of speleothems from the global speleothem database SISALv2. We perform case studies on a large ensemble of synthetic speleothems to systematically assess the resolution of age measurements necessary to reliably detect and model growth rate changes. These synthetic speleothems cover a large range of characteristic speleothem features observed in the SISALv2 database and are analyzed by six different age-depth modeling methods (linear regression, linear interpolation, copRa, StalAge, Bacon, and Bchron). Comparing the simulated changes with speleothems selected from SISALv2 according to these criteria can thus help to constrain past precipitation changes and subsequently confine uncertainty of future changes.
Paleozoic development of OIB and see-mounts in the Turkestan Ocean within the Khaidarkan and Ulug-Too deposits, South Tianshan (STS)

The study area is situated in the Ulug-Tau and Khaidarkan gold-antimony-mercury deposits in the South Tienshan (STS). Together with Khadamzhai, Chauvai, and Abshyr deposits, they can be grouped into one ore province. The STS consists mainly of middle and late Paleozoic marine sedimentary rocks, which were deposited in the Turkestan Ocean and on the adjacent continental margins. They crop out along with subordinate metamorphic rocks, arc-related and intraplate volcanic suites, and ophiolites. Various lithologies were juxtaposed together in an accretionary prism during the late Carboniferous - early Permian closure of the Turkestan Ocean.

In the investigated area, Late Silurian to Devonian limestones of the Aktur carbonate platform cover both the shales of the Pulgon Formation (Fm.) (Zarhar-Say) and the basalts with gabbro bodies. Gabbro specimens were sampled for absolute age determination by amphibole 40Ar/39Ar geochronology. Volcanic rocks related to the basement of the Silurian-Carboniferous Akturian carbonate platform, part of the regional nappes of Osh-Uratyube, have been studied by Biske et al., (2019) and our group. The nappe sits on top of basaltic rocks of the Chonkoy Fm. and andesites, tuffs, and carbonate rocks of the Dedebulak Fm. In the latter unit, the volcanic suite forms the lower member which is overlain by Cambrian limestone and dolomite with intercalations of radiolarite (upper member). The volcanic rocks at the base of the Aktur carbonate platform succession indicate the Early Paleozoic geodynamic situation in the Turkestan Ocean as well as about the structure of the Khaidarkan and Ulug-Too gold-antimony-mercury deposits. The Ulug-Tau orefield is situated along the mélange zone at the base of the Aktur nappe.

Results of geochemical and geochronologic analyses (in progress) show that the basalts and basaltic andesites of the lower member of the Dedebulak Fm. formed in an island-arc setting. These volcanic rocks confirm the existence of Early Paleozoic island arcs in the Turkestan Ocean. In a later stage, those arcs possibly died out and were overlapped by carbonate platforms. For the Aktur carbonate platform, it can be assumed that it was detached from the Cambrian island arc basement during the Late Carboniferous and was added to the accretionary prism as the Aktur Nappe. The Cambrian island arc basement (Dedebulak Fm.) formed another thrust-sheet unit as part of the accretionary prism. Plastic Silurian shales and other sediments, primarily located between the Aktur carbonate platform sediments and the Cambrian island arc volcanic rocks, were incorporated into the polymictic mélange.

 
Groundwater sensitivity to climate across Australia

Climate change is projected to significantly influence groundwater resources in many regions around the world. However, the Fifth Assessment Report of the IPCC states that it is still poorly understood how groundwater level and recharge has and will be impacted by climate change due to the limited groundwater observation records and the confounding influence from multiple drivers, such as climate, pumping, and land cover change. This study aims to understand the risks to groundwater by estimating the sensitivity of groundwater level and recharge across Australia to climate variability.

To achieve this we firstly used HydroSight, a time-series groundwater hydrograph modeling toolbox, to identify those sites having experienced minimal influence from anthropogenic impacts such as groundwater pumping or land cover changes. A total of 5077 sites were modeled, from which 336 sites were identified as having groundwater levels primarily driven by climate variations alone, with 245 sites located in Victoria. HydroSight groundwater simulations were then undertaken and used within multivariate regression to estimate the groundwater sensitivity to precipitation and potential evapotranspiration.

Results show that around one-fifth (n=72) sites are highly sensitive to changes in precipitation, with a sensitivity of more than 0.5m change in groundwater level per 1 percent shift in precipitation. The highly sensitive sites are mostly located in southwest Western Australia and southeastern Australia. The groundwater recharge sensitivity in Victoria shows a high spatial consistency which gradually increases from North to South. By quantifying the sensitivity of groundwater to historic climate variations, this study allows the identification of regions most vulnerable to climate change throughout Australia and hence a more targeted future climate adaptation strategy.
