Fluxes of particulate pelagic material were measured in the Pontevedra Ría (northwest Spain) using sediment traps moored at the base of the photic zone, deployed for 24 h periods from February to June 1998. Measurements of water column hydrography, chlorophyll, primary production and phytoplankton were taken. Samples were divided into low, moderate and high productivity periods, according to ph...

In the Gulf of Maine (GoM), a network of buoy hydrography measurements collected since 2001 provide a subsurface salinity time series showing a strong seasonal cycle and interannual variations that are both consistent with remote forcing of Gulf hydrography by upstream advection. These long-term mooring data are combined with satellite altimeter estimates of upper ocean current anomaly on the a...

[1] The surface water hydrography along the western Iberian margin, as part of the North Atlantic’s eastern boundary upwelling system, consists of a complex, seasonally variable system of equatorward and poleward surface and subsurface currents and seasonal upwelling. Not much information exists to ascertain if the modern current and productivity patterns subsisted under glacial climate conditi...

Understanding of the processes affecting recruitment of commercially important fish species is one of the major challenges in fisheries science. Towards this aim, we investigated the relation between North Sea hydrography (temperature and salinity) and fish stock variables (recruitment, spawning stock biomass and pre-recruitment survival index) for 9 commercially important fishes using spatiall...

Summertime oxygen depletion has been more and frequently observed in the bottom water of Bohai Sea last decade. Based on comprehensive hydrography microstructure measurements summer Sea, physical structure dissolved (DO) dynamics were investigated. The study area is characterized by strong tidal currents obvious horizontal temperature DO gradients boundary layer. forcing induces large near-bott...

Watershed delineation is a process for defining a land area that contributes surface water flow to a single outlet point. It is a commonly used in water resources analysis to define the domain in which hydrologic process calculations are applied. There has been a growing effort over the past decade to improve surface elevation measurements in the U.S., which has had a significant impact on the ...
