Journal ArticleDOI
TL;DR: This paper examined the influence of temperature on the timing of the spawning and migrations of North Sea mackerel using data from larvae CPR surveys, egg surveys and commercial landings from Danish coastal fisheries in the North Sea, Skagerrak, Kattegat, and inner Danish waters.

Journal ArticleDOI
TL;DR: In this article, upwelling conditions have been simultaneously analyzed along the western and northern coast of the Iberian Peninsula in terms of wind forcing and water temperature response, and it was found that the season under more favorable conditions corresponds to spring-summer (April-September) along the west coast and only to summer (June-to-August) on the northern one.

Journal ArticleDOI
TL;DR: In this paper, the authors evaluated the composition, abundance, distribution, and temporal variability of floating objects along the continental coast of central-southern Chile and the Patagonian fjords using ship surveys conducted in austral winter (July/August) and spring (November) of the years 2002-2005 and 2008.

Journal ArticleDOI
TL;DR: In this paper, a large number of sediment cores collected during 2005-2010 from the Taiwan Strait were analyzed for radionuclides ( 210 Pb, 137 Cs and 7 Be) to elucidate sedimentation dynamics in this all-important gateway linking two largest marginal seas in the western Pacific (namely, the South China Sea and the East China Sea).

Journal ArticleDOI
TL;DR: In this article, two research cruises were conducted in the N-S oriented macrobasin of the Moraleda Channel (42-47°S), which includes the E-W oriented Puyuhuapi Channel and Aysen Fjord, during two contrasting productive seasons: austral winter (27 July-7 August 2007) and spring (2-12 November 2007).

Journal ArticleDOI
TL;DR: In this article, the authors studied the water column properties (primary production, nutrients, and surface sediment characteristics) of the Chilean Patagonian fjords between 41°S and 55°S.

Journal ArticleDOI
TL;DR: In this article, a comprehensive 32 kHz multibeam bathymetry and backscatter survey of Cook Strait, New Zealand (∼8500 km2) is used to generate a regional substrate classification map over a wide range of water depths, seafloor substrates and geological landforms using an automated mapping method based on the textural image analysis of Backscatter data.

Journal ArticleDOI
TL;DR: In this paper, the potential sources and composition of organic matter across fjord ecosystems were evaluated using stable isotope (δ13C) and lipid (fatty acid composition) biomarker analyses.

Journal ArticleDOI
TL;DR: In this paper, the relative distribution of allochthonous (i.e., terrigenous) organic matter in the complex, continuous, river-fjord-sound-channel-gulf system of Chile's North Patagonia (41.5-46.5°S) was investigated to establish whether this organic matter can reach the open ocean or whether it is largely retained near its fluvial sources.

Journal ArticleDOI
TL;DR: In this article, the authors summarize the hydrographical features with an emphasis on upwelling, which is the key driver of biogeochemical processes and ecosystem dynamics in the Taiwan Strait.

Journal ArticleDOI
TL;DR: In this article, concentrations of five heavy metals (Hg, Cd, Pb, Cu and Zn) were determined in tissues of wild mussels (Mytilus galloprovincialis ) collected at 41 stations located on the Spanish Atlantic and Northern coasts to assess the levels and spatial distribution of metals in the environment.
