TL;DR: In this article, the results show that global trends have significant effects on local hydrographical and biological conditions in the coastal marine environments of Western Antarctica, and that the Southern Annular Mode (SAM) climate signal was apparent in fluctuating interannual pattcern of the hydrographic variables in the outer Potter Cove and bottom waters whereas surface hydroggraphy was strongly governed by the local forcing of glacier melt.

TL;DR: High priority should be given to developing research programs that not only construct and apply IBMs but also that measure the aspects of larval behavior and physiology as well as aspects of the larval environment needed to parameterize them to strengthen confidence in IBM-derived estimates of mortality and the processes responsible for death of larvae in the sea.

TL;DR: In this article, a coupled model called POLCOMS-ERSEM has been implemented in the North Western European shelf with a new parameterization for alkalinity explicitly accounting for riverine inputs and the influence of biological processes.

TL;DR: In this article, the origin and composition of sediment organic matter (SOM) were investigated together with its spatial distribution in the Arcachon Bay - a macrotidal lagoon that shelters the largest Zostera noltii meadow in Europe.

TL;DR: In this paper, the authors present results on phytoplankton and bacterial production and related hydrographic properties collected on nine annual summer cruises along the western Antarctic Peninsula.

TL;DR: In this paper, a three-dimensional hydrodynamic model is applied to the Mobile Bay system to study water and salt exchange with the northern Gulf of Mexico via Main Pass (MP) and eastern Mississippi Sound via Passaux-Herons (PaH).

TL;DR: In this paper, the spatial patterns of assemblages during late summer, 2007, and late spring-early summer, 2008 in the Amundsen and Ross Seas were investigated.

TL;DR: In this paper, the redoxclines of two anoxic deeps from the Baltic Sea (Landsort Deep and Gotland Basin) and two seasonally anoxic freshwater lakes (Lake Dagow and Fuchskuhle, Germany) were determined.

TL;DR: In this paper, the authors use a statistical emulator technique, polynomial chaos expansion, to estimate time-dependent values for two parameters of a 3D biological ocean model, and derive (hindcast) state estimates in two distinct ways: (1) by using the emulator-based interpolation and (2) by performing model runs with timedependent parameters.

TL;DR: In this article, the authors used the concepts of the Constituent-oriented Age and Residence time Theory (CART) to compute timescales related to the water renewal in the Scheldt Estuary (The Netherlands/Belgium).

TL;DR: In this paper, the authors examined various fishing management options to recover exploited marine resources and ecosystems of the Northern-Central Adriatic Sea and concluded that current fishing management does not have clear beneficial impacts for the recovery of exploited resources.

TL;DR: In this paper, a multivariate sequential data assimilation approach, Localized Ensemble Kalman Filter (LEnKF), was used to assimilate daily satellite observations of ocean chlorophyll into a three-dimensional physical-biological model of the Middle Atlantic Bight (MAB) for the year 2006.

TL;DR: In this paper, the vertical thermohaline structure along the western boundary of the Bay of Bengal revealed many undulations during April-May 2003, and a prominent feature noticed was a dome in the northwestern boundary, which was found to be a cyclonic eddy (NCE), which altered the ambient temperature by 6°C and salinity by 0.8psu.

TL;DR: In this paper, the authors consider the problem of combined state-parameter estimations in biased nonlinear models with non-Gaussian extensions of the Deterministic Ensemble Kalman Filter (DEnKF).

TL;DR: In this paper, the authors applied multivariate analysis to geochemical data for soft-bottom sediments from the Portuguese continental shelf to determine their provenance and to identify the main factors governing the sediment distribution patterns.

TL;DR: In this article, the authors apply the model ERGOM to simulate the consequences of climate change as well as the combination of Climate Change with nutrient load reductions according to the Baltic Sea Action Plan (BSAP).

TL;DR: In this paper, the authors examined the long-term variability in the abundance of yellowtail Seriola quinqueradiata and its relationship with sea water temperature in the Japan Sea, which is one of the most rapidly warming large marine ecosystems in the world ocean.

TL;DR: In this paper, a comparison was made between various ways of analysing benthic macrofaunal datasets using both taxon names as well as functional traits, showing that taxon richness and overall faunal biomass were highest at the shallowest stations, and lowest in the depressions and ice-influenced areas.

TL;DR: A climatology for the mixed layer depth (MLD) in the East/Japan Sea was produced using temperature profile data collected from 1931 to 2005 as mentioned in this paper, which is defined as the depth at which the temperature differs from that at 10m depth by 0.2°C.

TL;DR: In this article, hydrographic data obtained in late winter in 2010 after severe storms in the Western Mediterranean (WMED) were analyzed. And they showed that, under severe winter conditions, the formation area of WIW is larger than previously thought and the salinity and temperature ranges for this water mass are also wider than those traditionally accepted in the literature.

TL;DR: In this article, the authors show that nutrient loading of aquatic ecosystems results in more food for benthic macrofaunal communities but also increases the risk of hypoxia.

TL;DR: In this paper, the authors used MODIS-Aqua visible and near-infrared wavelengths to study and quantify the extreme sea ice event in the 2009-2010 winter and the interannual variability of the regional sea ice properties, as well as the relationship between sea ice and the climate variability in the Bohai Sea.

TL;DR: Overall, spatial patterns of mesozooplankton and food availability matched weakly, suggesting a poor coupling between consumers and their prey communities at the time, and significant correlations were found particularly with large autotrophs and heterotrophS.

TL;DR: Starvation rate, edge of death, and time to death are viable proxies for the physiological processes under food deprivation of individual fish pre-recruits in the laboratory and provide useful metrics for research on the role of starvation in the sea.

TL;DR: The shifts in mortality schedules and the causes through the early life history are investigated in relation to concepts such as ‘nursery ground carrying capacity’ and ‘self-thinning’.

TL;DR: In this paper, the storage rate of anthropogenic CO 2 (Cant) in the South Atlantic basin was estimated to be 0.92 −0.13 −1.0 Pg C y −1 or 0.055 −0.02 Pg c y − 1, which is 13% −35% higher than previous estimates in this area.

TL;DR: Based on spectral features of the sea ice reflectance, a regionally optimized ice-detection algorithm is proposed in this article, which shows considerable improvements in detecting sea ice over the Bohai Sea region, compared with a previous MODIS global sea ice detection algorithm.

TL;DR: In this article, the authors examined the footprint of moorings that underpin the Australian Integrated Marine Observing System (IMOS) based on sea surface height, temperature, and velocity from a 17-year model run.

TL;DR: In this paper, a combination of natural isotope tracers, elemental composition and physico-chemical variables allowed distinguishing two sources of organic matter within the eddy dipole, where cyclonic water promoted new production by upwelling nutrient-rich deep waters into the euphotic zone, and anti-cyclonic surface POM containing coastal POM was downwelled into deeper layers where decomposition greatly affected its composition.

TL;DR: In this paper, the authors estimate annual source apportioned nitrogen (N) and phosphorus (P) emissions into the Vistula and Oder basins in 1995-2008, thus, during the transition period in Poland, characterized by changes in both agricultural sector and handling of point source pollution.
