TL;DR: In this paper, the impacts of anthropogenic climate change on marine ecosystems are evaluated in the context of the "normal" climate cycles and variability which have caused fluctuations in fisheries throughout human history.

TL;DR: In this paper, the authors review how exploitation, by altering the structure of populations and ecosystems, can modify their ability to respond to climate and show that demographic effects of fishing (removal of large-old individuals) can have substantial consequences on the capacity of populations to buffer climate variability through various pathways (direct demographic effects, effects on migration, parental effects).

TL;DR: There are still many challenges facing the end-to-end modelling field, particularly when long simulation periods are called for, but perhaps the greatest ones are: non-stationarity introduced by shifting climate, biodiversity and evolution; representing human responses; and handling uncertainty.

TL;DR: In this paper, the authors discuss how fishing and climate forcing interact on individual fish, marine populations, marine communities, and ecosystems to bring these levels into states that are more sensitive to (i.e. more strongly related with) climate forcing.

TL;DR: In this paper, the authors review some of the ecosystem responses to climate variability and discuss the possible mechanisms through which climate acts, such as temperature, sea ice, turbulence, and advection.

TL;DR: In this article, the authors identify quantitative relationships between nutrient input and proliferation of specific algal species and develop forecasts and predictions, both on the short term and on the long term, to enable strategic planning to prevent HAB events, mitigate their impacts, or estimate the interactive effects of anthropogenic activities and climate change.

TL;DR: In this paper, the authors summarize the apparent within and between ocean basin teleconnection patterns in a comparative framework using particularly suggestive examples and unravel physical-biological linkage mechanisms between a climate signal and fish populations.

TL;DR: In this paper, two regional data sets for greenhouse gas emission scenarios, A1B and B1, for the period 1960 to 2100, were used to force transient simulations with a 3D ecosystem model of the Baltic Sea.

TL;DR: A review of the current knowledge made available through the rapidly increasing literature on the topic, with particular emphasis on the work within the Global Ocean Ecosystems Dynamics (GLOBEC) program is presented in this paper.

TL;DR: In this article, the authors discuss large-scale climate variability for several marine ecosystems and suggest types of ecosystem responses to climate change. And they conclude that most climate variability is accounted for by the combination of intermittent 1-2-year duration events, e.g. the cumulative effect of monthly weather anomalies or the more organized El Nino/La Nina, plus broadband “red noise” intrinsic variability operating at decadal and longer timescales.

TL;DR: Based on the analysis of the changes of the coastlines, multi-temporal Landsat images and a SPOT scene have been used, in combination with topographical and nautical data as discussed by the authors, it can be concluded that the largest variations in the position of the coastline over time occurred in the Nansha Development Zone, situated in the Northern part of Lingdingyang bay.

TL;DR: In this paper, four short sediment cores (45 60 cm long) recovered within the PECAI project from the Pearl River Estuary have been analyzed for grain size and geochemistry to reveal geochemical source and deposition environment and to assess enrichment and pollution of heavy metals in the sediments.

TL;DR: A review of recent within-and between-region analyses of zooplankton time series can be found in this paper, where the authors suggest some priorities for future work.

TL;DR: The results from a workshop of the OSPAR Intersessional Correspondence Group on Eutrophication Modelling (ICG-EMO) held in Lowestoft in 2007 are presented in this article.

TL;DR: The efficacy of two optimisation techniques, a variational adjoint (VA) and a micro genetic algorithm (μGA), was studied with respect to the calibration of two simple one-dimensional models for Arabian Sea data and it is argued that the first approach is unrealistically precise as it ignores any uncertainty in the unconstrained parameters, while solutions from the second approach may be unnecessarily broad.

TL;DR: This article evaluated the 20th century hindcasts of selected variables relevant to several large marine ecosystems and examined 21st century projections by a subset of these models under the A1B (middle range) emission scenario.

TL;DR: In this paper, a high-resolution global coupled ice-ocean model is used to identify two mode waters in the Barents Sea branch: a halocline water produced by surface cooling at shallow convective sites in the northern Bars Sea, and bottom water formed from NAW in the southeastern Barshes Sea via full-depth convection and mixing.

TL;DR: In this paper, water level variations were used to calculate cold-front-induced water exchange fluxes for three Louisiana bays and five largest flushing events were all associated with migrating extra-tropical cyclones with frontal orientations perpendicular to the coastline, suggesting that wind direction is an important component in determining the flushing rate.

TL;DR: In this article, Chen et al. studied Hurricane Ike's storm surge along the Texas-Louisiana coast using the fully nonlinear Finite-Volume Coastal Ocean Model (FVCOM) with a high-resolution unstructured mesh.

TL;DR: In this paper, the authors proposed a community-focused approach to predict community responses to climate change, based on knowledge of the processes that determine the size-structure of communities, using metabolic scaling, predator-prey interactions and energy transfer in size-based food webs.

TL;DR: In this paper, a three-dimensional water quality model was developed to study the dissolved oxygen (DO) budget of the Pearl River Estuary (PRE) in summer and to identify the roles that various physical and biochemical processes played in DO dynamics.

TL;DR: In this article, the authors used the data base MEDATLAS and data from more recent monitoring programs to construct the longest temperature and salinity time series ever analyzed in the Western Mediterranean (1900 to 2008).

TL;DR: In this paper, a seasonal sediment plume is attributed to sediment resuspension due to the strong vertical mixing and convection driven by the cooling of the upper ocean and enhanced surface winds during the winter season.

TL;DR: These spatio-temporal foraging patterns seem to relatively closely match the main features of the integrated meso-zooplankton distribution in the North Atlantic.

TL;DR: In this paper, the authors describe the development of empirical models for the potentially domoic acid-producing Pseudo-nitzschia species complex present in the Chesapeake Bay, developed from a 22-year time series of cell abundance and concurrent measurements of hydrographic and chemical properties.

TL;DR: F fuzzy logic was applied to simulate observed Phaeocystis bloom dynamics in coastal waters of the North Sea and foam formation on adjacent beaches to communicate current understanding of foam formation, enhances the predictability of these events, and provides a basis for more detailed modelling efforts.

TL;DR: Lara, Ruben, and Jose as mentioned in this paper presented a paper on tropical marine ecology and its application in the field of marine ecology, which is published by the Consejo Nacional de Investigación Cientificas Cientícias y Tecnicas (CICTE).

TL;DR: In this article, the authors analyzed factors regulating phytoplankton variability in the Arabian (Persian) Gulf were analyzed on the basis of satellite observations and meteorological data (1997-2009), including remotely-sensed chlorophyll a concentration (CHL), sea surface temperature, wind, solar radiation, precipitation, and aerosols.

TL;DR: An argument is offered for the potential utility of such widely recognizable schematic concepts in offering relatively well-understood, fairly well-defined frameworks for comparative identification and elaboration of important mechanistic linkages between climate variability and fishery dynamics, as well as in easing effective communication among scientists from different regions and disciplinary backgrounds.

TL;DR: In this article, the distributions of total CO2 and total alkalinity were determined in the Baltic Sea in summer 2008 and winter 2009, respectively, and the cruises covered all major basins between the Kattegat, the north of the Gulf of Bothnia and the east of the south of Finland.
