TL;DR: In this paper, the authors compare and synthesize results from these studies and suggest that water temperature (relatively slowly and smoothly varying in aquatic environments) is also used by zooplankton as a timing cue, much as terrestrial biota uses day-length.

TL;DR: Not only the need to address uncertainty in ecosystem models, but also the feasibility and benefits of doing so are emphasized.

TL;DR: In this paper, the authors demonstrate how a simple parameterization of a zooplankton community response affects simulated community structure, diversity and dynamics, and motivate development of more detailed representations of top-down processes essential for investigating the role of diversity in marine ecosystems.

TL;DR: A comprehensive study of water properties for the Bohai Sea (BS), Yellow Sea (YS), and East China Sea (ECS) has been carried out with 8-year observations between 2002 and 2009 from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the Aqua platform as discussed by the authors.

TL;DR: In this paper, the authors elucidate the climatic background of the return of anchovies and sardines to the northern European shelf seas and the changes in the North Sea fish community in the mid-1990s in response to climate variability.

TL;DR: In this article, the importance of considering spatio-temporal variations in isotopic signatures of consumers when using δ13C and especially δ15N values in open ecosystems with complex food webs, using the Bay of Biscay (North-East Atlantic) as a case study.

TL;DR: In this paper, seasonal variability in satellite chlorophyll a concentrations (SCHL) in the Yellow Sea and the East China Sea (YECS) was investigated using 10-year averages of monthly data collected between September 1997 and October 2006.

TL;DR: The Southern Ocean supports diverse and unique ecosystems that have been impacted by more than two centuries of exploitation and are now experiencing rapid changes in ocean temperature and seasonal ice cover due to climate warming as mentioned in this paper.

TL;DR: A 3-D individual-based model that incorporates temperature-dependent and, for some cases, food-dependent development rates shows that C. finmarchicus and C. marshallae are unable to penetrate, survive, and colonize the Arctic Ocean under present conditions of temperature, food availability, and length of the growth season, mainly due to insufficient time to reach their diapausing stage.

TL;DR: In this paper, a method for predicting coastal surface-water CO2 from remote sensing data, based on self organizing maps (SOMs) and a nonlinear semi-empirical model of surface water carbonate chemistry, was presented.

TL;DR: Analysis of the range of ecosystem states observed interannually and understanding system sensitivity to variability among key trophic groups improves the ability to predict NCC ecosystem response to short- and long-term environmental change.

TL;DR: In this paper, the authors explore the impact of fishery policies on management objectives at different spatial scales, from single Marine Sanctuaries to the entire Northern California Current, using an Atlantis end-to-end model.

TL;DR: In this article, the seasonal variations of the West Florida Continental Shelf (WFS) circulation and sea level are described using observations of velocity from an array of moored acoustic Doppler current profilers and various ancillary data.

TL;DR: One of the first comparative investigations between upwelling and predators, from fish to marine mammals and birds within a geographically restricted area, demonstrates often difficult to establish ‘‘bottomup’’ trophic interactions, and establishes the importance of seasonality of up welling to various trophIC connections and predator demographic traits.

TL;DR: In this paper, a sequential t-test algorithm for analyzing regime shifts (STARS) to physical (wind and upwelling) and biological (rock-lobster catch and growth, Bank Cormorant abundance) data for the southern Benguela inshore region and performed sensitivity tests on each of the variables.

TL;DR: An array of mooring lines deployed between 300 and 1900 m depth along the Lacaze-Duthiers and Cap de Creus canyons and in the adjacent southern open slope was used to study the water and sediment transport on the western Gulf of Lions margin during the 2006 intense cascading period as mentioned in this paper.

TL;DR: In this paper, the authors developed spatially-explicit oceanographic and ecological descriptions of the central California Current region and identified five ecologically important areas based on spatial integration of environmental and biotic features.

TL;DR: The salp Salpa thompsoni has exhibited increased abundance in high latitude portions of the Southern Ocean in recent decades and is now frequently the numerically dominant zooplankton taxon in the Antarctic Peninsula region as mentioned in this paper.

TL;DR: In this paper, a volumetric census is presented, which confirms Circumpolar Deep Water (CDW; 53 −± 3% of the Southern Ocean volume) as the most volumetrically important water mass in the SO; followed by Antarctic Bottom Water (AABW; 17 −± 0.9%) and North Atlantic Deep Waters (NADW; 13 −± −0.8%).

TL;DR: This article examined the trends and variability in temperature of the northwest European shelf seas over the period 1960-2004 using four approaches: a regional model simulation (using the Proudman Oceanographic Laboratory Coastal Ocean Modelling System; POLCOMS), in situ multi-annual timeseries observations, satellite remote sensed (AVHRR) sea surface temperature (SST), and an analysis of data held in an international database at the International Council for the Exploration of the Sea (ICES).

TL;DR: In this paper, the authors evaluated the upper ocean variability at different stages in the evolution of the tropical cyclones Nargis and Laila over the Bay of Bengal (BoB) during May 2008 and May 2010 respectively.

TL;DR: In this article, the authors analyzed and compared Mediterranean mesozooplankton time series spanning 1957-2006 from six coastal stations in the Balearic, Ligurian, Tyrrhenian, North and Middle Adriatic and Aegean Sea.

TL;DR: The overall persistence of the basic community is interpreted as resulting from the flexibility of coastal species to adapt to variation in environmental conditions, even when there was high variability in the environmental parameters.

TL;DR: In this article, two zooplankton time series from the coastal upwelling region off Chile were studied in terms of copepod biomass and abundance in relation with up-welling variation.

TL;DR: In this article, current velocities and vertical sediment fluxes in the Var submarine canyon were assessed at three stations respectively at 800m, 1200m and 1800m depth, using moorings deployed for 4 months during winter 2008-2009.

TL;DR: In this article, an end-to-end ecosystem model was developed to explore the possible scale and mechanisms of interactions between pelagic and demersal fishing in the North Sea.

TL;DR: In this paper, the authors compared the current meter data collected in four selected periods between 1987 and 2008 with a high-resolution coupled ice-ocean circulation model, CECOM (Canadian East Coast Ocean Model) covering the entire area.

TL;DR: In this paper, a glider mission was conducted in August 2008, closely co-located and almost simultaneously launched with a JASON 2 altimetric pass, to fully characterize the currents associated with regional (sub)mesoscale processes regularly observed to the north of Mallorca (Mediterranean Sea).

TL;DR: In this article, the multi-decadal variations of the Multivariate ENSO Index (MEI) and the Pacific Decadal Oscillation (PDO) index were studied to determine their influence on tropical cyclones (TCs) using the empirical mode decomposition (EMD) method and Hilbert spectral analysis.

TL;DR: In situ and modeled spatial distribution of squat lobster larvae over the continental shelf off south central Chile (35-37°S) was analyzed along with currents and hydrography.
