The article is devoted to identifying undrained zones of sediments of the Sangopai formation for the purpose of testing and increasing oil reserves. The importance of a detailed comprehensive analysis of the geological structure of the object is demonstrated from the point of view of general ideas about the history of sedimentation, analysis of well-logging operations, reinterpretation of the values of the actual saturation of the reservoir, as well as the history of the current state of development. Thanks to the research carried out, the external oil and gas contours were revised and mapped, and for the purpose of additional exploration, drilling of a sidetrack was planned. Based on the results of testing the formation in an area that was previously assessed an unpromising, an influx of oil production in the flowing mode was obtained, and prompt registration was made on the State balance of oil and dissolved gas reserves. Based on the developed methodology for substantiating the productivity of sediments and test results, more than 20 sidetracks were implemented, which has high practical value when planning geological and technical activities at the studied site and practically eliminates low-efficiency operations.

Contribution of airborne microbes to bacterial production and N2 fixation in seawater upon aerosol deposition

Published: December 2015

AbstractAerosol deposition may supply a high diversity of airborne microbes, which can affect surface microbial composition and biological production. This study reports a diverse microbial community associated with dust and other aerosol particles, which differed significantly according to their geographical air mass origin. Microcosm bioassay experiments, in which aerosols were added to sterile (0.2 µm filtered and autoclaved) SE Mediterranean Sea (SEMS) water, were performed to assess the potential impact of airborne bacteria on bacterial abundance, production, and N2 fixation. Significant increase was observed in all parameters within a few hours, and calculations suggest that airborne microbes can account for one third in bacterial abundance and 50–100% in bacterial production and N2‐fixation rates following dust/aerosol amendments in the surface SEMS. We show that dust/aerosol deposition can be a potential source of a wide array of microorganisms, which may impact microbial composition and food web dynamics in oligotrophic marine systems such as the SEMS.
Quantifying the effect of vegetation change on the regional water balance within the Budyko framework
Authors: Zhang Shulei , Yang Hanbo , Yang Dawen , Jayawardena A. W. 
Published: December 2015

AbstractThe Budyko framework is widely used to investigate the impacts of climate and landscape changes on regional hydrology, but quantifying the effect of vegetation change is still a challenge due to the lack of an explicit expression of vegetation in Budyko equations. This study establishes a relationship between the change in the landscape parameter in a Budyko equation and vegetation change (represented by fPAR, the fraction of Photosynthetically Active Radiation absorbed by vegetation) for catchments in China, where, due to large‐scale soil and water conservation projects implemented by the Chinese government, vegetation and regional hydrology have changed substantially over the past 30 years. The ratio of landscape parameter change to the change in fPAR has a strong relationship with the aridity index, and thus, vegetation change can be converted into a change in the landscape parameter. Then, the fPAR elasticity of runoff is introduced and formulated under the Budyko framework. It provides a useful tool for the quantitative evaluation of the regional hydrological response to vegetation change, but the proposed relationship still needs to be evaluated in other catchments around the globe where large‐scale afforestation or vegetation recovery has occurred.

AbstractFour moorings were deployed near “Dragon Flag,” an active hydrothermal vent in the valley of the Southwest Indian Ridge. The goal was to examine the variability of currents and temperature, which will guide the trajectory of spreading plumes. The mean current was cross‐isobath, and the circulation was characterized by a submesoscale circulation. Observed currents also showed fluctuations with periods of 1–15 days. The inferred phase speed and wavelength for the wave with a period of 4.4 day are 10.4 km d−1 and 45.8km, respectively, which are consistent with the topographic Rossby wave theory. The persistent warming tendency with corresponding variation of salinity based on background θ‐S properties may be caused by background circulation and divergence of the water column. The warming or cooling episodes were most likely as signatures of isopycnal surface depression or uplifting induced by the moving of mesoscale eddies. Well‐resolved rotary spectra exhibited important nonlinear interactions between inertial and semidiurnal tide in the velocity and temperature records. Amplification of near‐inertial currents in the near bottom is also exposed. These discoveries provided new evidence for the nonlinear interaction and trapped near‐inertial waves by the ridge, which occurred in the deep ocean of the Southern Hemisphere. Such nonlinear interaction may represent a significant energy loss pathway for the internal waves, and part of the decay of such motion would likely result in increased mixing to maintain the abyssal stratification. Enhanced near‐inertial motions can play a major role for the local advection of hydrothermal plumes.
Sea surface height and dynamic topography of the ice‐covered oceans from CryoSat‐2: 2011–2014
Authors: Kwok Ron , Morison James 
Published: December 2015

AbstractWe examine 4 years (2011–2014) of sea surface heights (SSH) from CryoSat‐2 (CS‐2) over the ice‐covered Arctic and Southern Oceans. Results are from a procedure that identifies and determines the heights of sea surface returns. Along 25 km segments of satellite ground tracks, variability in the retrieved SSHs is between ∼2 and 3 cm (standard deviation) in the Arctic and is slightly higher (∼3 cm) in the summer and the Southern Ocean. Average sea surface tilts (along these 25 km segments) are 0.01 ± 3.8 cm/10 km in the Arctic, and slightly lower (0.01 ± 2.0 cm/10 km) in the Southern Ocean. Intra‐seasonal variability of CS‐2 dynamic ocean topography (DOT) in the ice‐covered Arctic is nearly twice as high as that of the Southern Ocean. In the Arctic, we find a correlation of 0.92 between 3 years of DOT and dynamic heights (DH) from hydrographic stations. Further, correlation of 4 years of area‐averaged CS‐2 DOT near the North Pole with time‐variable ocean‐bottom pressure from a pressure gauge and from GRACE, yields coefficients of 0.83 and 0.77, with corresponding differences of <3 cm (RMS). These comparisons contrast the length scale of baroclinic and barotropic features and reveal the smaller amplitude barotropic signals in the Arctic Ocean. Broadly, the mean DOT from CS‐2 for both poles compares well with those from the ICESat campaigns and the DOT2008A and DTU13MDT fields. Short length scale topographic variations, due to oceanographic signals and geoid residuals, are especially prominent in the Arctic Basin but less so in the Southern Ocean.
Interannual and seasonal variabilities in air‐sea CO2 fluxes along the U.S. eastern continental shelf and their sensitivity to increasing air temperatures and variable winds

AbstractUncertainty in continental shelf air‐sea CO2 fluxes motivated us to investigate the impact of interannual and seasonal variabilities in atmospheric forcing on the capacity of three shelf regions along the U.S. eastern continental shelf to act as a sink or source of atmospheric CO2. Our study uses a coupled biogeochemical‐circulation model to simulate scenarios of “present‐day” and “future‐perturbed” mesoscale forcing variability. Overall, the U.S. eastern continental shelf acts as a sink for atmospheric CO2. There is a clear gradient in air‐sea CO2 flux along the shelf region, with estimates ranging from −0.6 Mt C yr−1 in the South Atlantic Bight (SAB) to −1.0 Mt C yr−1 in the Mid‐Atlantic Bight (MAB) and −2.5 Mt C yr−1 in the Gulf of Maine (GOM). These fluxes are associated with considerable interannual variability, with the largest interannual signal exhibited in the Gulf of Maine. Seasonal variability in the fluxes is also evident, with autumn and winter being the strongest CO2 sink periods and summer months exhibiting some outgassing. In our future‐perturbed scenario spatial differences tend to cancel each other out when the fluxes are integrated over the MAB and GOM, resulting in only minor differences between future‐perturbed and present‐day air‐sea CO2 fluxes. This is not the case in the SAB where the position of the along‐shelf gradient shifts northward and the SAB becomes a source of CO2 to the atmosphere (0.7 Mt C yr−1) primarily in response to surface warming. Our results highlight the importance of temperature in regulating air‐sea CO2 flux variability.
Using GNSS signals as a proxy for SAR signals: Correcting ionospheric defocusing

Published: December 2015

AbstractUltrahigh frequency space‐based synthetic aperture radar (SAR) can suffer from the degrading effects of a scintillating ionosphere which modulates both the phase and the amplitude of the radar signal. In this paper, we use Global Navigation Satellite System (GNSS) signals to synthesize an L‐band SAR point spread function (PSF). The process of transforming the GNSS signal to the equivalent SAR PSF is described. The synthesized PSF is used to explore the possibility of using a phase correction determined from a point target in a SAR image to correct the ionospheric degradation. GNSS data recorded on equatorial Ascension Island during scintillation events are used to test the feasibility of this approach by applying a phase correction to one GNSS receiver from another located along a magnetic east‐west baseline. The peak‐to‐sidelobe ratios of the synthesized L‐band SAR point spread functions before and after the correction are compared, and it is shown that this approach improves the L‐band PSF over distances of ~3000 m in the ionosphere, corresponding to 6000 m on the ground.
ABayesian hierarchical approach to model seasonal algal variability along an upstream to downstream river gradient

Published: December 2015

AbstractModeling to accurately predict river phytoplankton distribution and abundance is important in water quality and resource management. Nevertheless, the complex nature of eutrophication processes in highly connected river systems makes the task challenging. To model dynamics of river phytoplankton, represented by chlorophylla(Chla) concentration, we propose a Bayesian hierarchical model that explicitly accommodates seasonality and upstream‐downstream spatial gradient in the structure. The utility of our model is demonstrated with an application to the Nakdong River (South Korea), which is a eutrophic, intensively regulated river, but functions as an irreplaceable water source for more than 13 million people. Chlais modeled with two manageable factors, river flow, and total phosphorus (TP) concentration. Our model results highlight the importance of taking seasonal and spatial context into account when describing flow regimes and phosphorus delivery in rivers. A contrasting positive Chla‐flow relationship across stations versus negative Chla‐flow slopes that arose when Chlawas modeled on a station‐month basis is an illustration of Simpson's paradox, which necessitates modeling Chla‐flow relationships decomposed into seasonal and spatial components. Similar Chla‐TP slopes among stations and months suggest that, with the flow effect removed, positive TP effects on Chlaare uniform regardless of the season and station in the river. Our model prediction successfully captured the shift in the spatial and monthly patterns of Chla.

AbstractTopological persistence is a powerful and general technique for characterizing the geometry and topology of data. Its theoretical foundations are over 15 years old and efficient computational algorithms are now available for the analysis of large digital images. We explain here how quantities derived from topological persistence relate to other measurements on porous materials such as grain and pore‐size distributions, connectivity numbers, and the critical radius of a percolating sphere. The connections between percolation and topological persistence are explored in detail using data obtained from micro‐CT images of spherical bead packings, unconsolidated sand packing, a variety of sandstones, and a limestone. We demonstrate how persistence information can be used to estimate the percolating sphere radius and to characterize the connectivity of the percolating cluster.

Published: December 2015

AbstractPeatland drainage has been an important component of forestry management in the boreal zone and the resulting ditch networks are maintained regularly to sustain forest productivity. In Finland, this is recognized as the most detrimental forestry practice increasing diffuse loads of suspended solids. Alongside forestry management on peatlands, interest in peatland restoration has grown lately. Distributed hydrological modeling has the potential to address these matters by recognizing relevant physical mechanisms and identifying most suitable strategies for mitigating undesired outcomes. This study investigates the utility of such a modeling approach in a drained peatland forest environment. To provide a suitable tool for this purpose, we coupled channel network flow to the three‐dimensional distributed hydrological model FLUSH. The resulting model was applied to a 5.2 ha drained peatland forest catchment in Eastern Finland. The model was calibrated and validated using field measurements obtained over frost‐free periods of five months. The application showed that distributed modeling can disentangle the importance of spatial factors on local soil moisture conditions, which is significant as peatland drainage aims to control these conditions. In our application, we limited the spatial aspect to the topography and the drainage network, and found that the drainage configuration had a clear effect on the spatial soil moisture patterns but that the effect was less pronounced during the wetter summer. Future applications of distributed modeling in this field comprises investigating the impacts of other spatial factors, modeling channel erosion and solid transport to address strategies for their mitigation, and evaluating restoration schemes.
