TL;DR: In this paper, a review of recent contributions to second-order turbulence modelling is presented, with an emphasis on models of the coastal ocean, and the model performance is evaluated for a number of idealised entrainment scenarios that are typical for shelf seas: entraining in linearly stratified and two-layer fluids caused by (a) surface wind stress (b) bottom stress due to water motion driven by a barotropic pressure gradient (c) bottom jet.

TL;DR: The key limiting factor for the coastward distribution of Prochlorococcus in the East China Sea were considered to be the movements of the Kuroshio Current and the Taiwan Warm Water Currents year around, temperature in winter and freshwater input in summer.

TL;DR: A dedicated trawling experiment was performed at three sites on the Gulf of Lion continental shelf, with the aim of assessing the resuspension of particulate and dissolved matter triggered by different types of trawls on muddy sediments as discussed by the authors.

TL;DR: In this paper, the coastal upwelled waters of the Guajira coast, the most northerly peninsula of South America, were studied on the basis of historical data bases, remotely sensed data, and three oceanographic cruises.

TL;DR: Water column and hydrodynamic records from coastal observation platforms (WAVCIS network) are combined with seabed sampling 4-7 days after passage of Hurricane Lili, to examine the impact of these events on the Atchafalaya inner shelf as mentioned in this paper.

TL;DR: In this article, microstructure measurements taken on the Monterey Bay continental shelf, within 4 km of the shelf break, reveal a complex mixing environment, including a large, high-aspect-ratio, downslope-propagating nonlinear internal solitary-like waves of elevation.

TL;DR: In this article, a short cruise (SARHYGOL 3; June 13-15, 2000) throughout the Gulf of Lions, NW Mediterranean Sea was used to collect ADCP, thermosalinograph, and meteorological data.

TL;DR: In this article, the authors used the data from the US Geological Survey to estimate sediment accumulation rates (SARs) at prescribed depths (70 and 110m) and distances (0-40-km north and south along-shelf) from each of the major rivers.

TL;DR: The Eulerian-Lagrangian finite difference/finite volume model designed to simulate 3D baroclinic circulation across river-to-ocean scales is described in this article.

TL;DR: In this article, a north-south transect crossing the quasi-permanent upwelling area and the front which usually occupies the north-western part of the Alboran Sea (Western Mediterranean) was sampled 16 times during four cruises, covering an annual cycle in order to study the coupling between hydrodynamics and phytoplankton spatial distribution.

TL;DR: The fine-grained fraction flux is at least 2.5 times larger than the coarser fractions flux as mentioned in this paper, which is consistent with the grain size of material collected in sediment traps.

TL;DR: The circulation and structure of the coastal upper ocean during the relaxation after an upwelling event around Cape Sao Vicente, the southwestern tip of Iberian Peninsula, are described in this paper.

TL;DR: In this article, the influence of the Atchafalaya River on stratigraphic evolution of the inner continental shelf in the northern Gulf of Mexico was examined using geochemical, geochemical and shallow acoustic data.

TL;DR: In this paper, it was shown that atmospheric nitrogen deposition in summer to nutrient depleted, well lit, surface waters in coastal seas stimulates phytoplankton blooms and that reducing the input of nitrogen from the atmosphere will reduce total nitrogen loads to coastal seas and hence may decrease eutrophication problems.

TL;DR: In this article, features extracted from echosounder bottom returns are compared with the ground truth in a North Sea survey area, which consists of 50 grab samples for which the grain size distribution, and the gravel and shell contents were determined.

TL;DR: In this article, four bottom-mounted current profilers were deployed across the Taiwan Strait from September 28 to December 14, 1999 to monitor the current velocity when the northeast monsoon was strong.

TL;DR: In this paper, the authors diagnose the momentum balance over the West Florida Shelf using observations of currents, bottom pressures, temperatures, winds, and coastal sea levels, along with hydrographic data from 32 monthly cruises spanning summer 1998 to winter 2001.

TL;DR: A coupled three-dimensional physical-biogeochemical model was developed in order to simulate the ecological functioning of the Rio de la Plata estuary and plume as discussed by the authors.

TL;DR: In this paper, the effects of bottom trawling on quantity and the biochemical composition of sediment organic matter were assessed, along a gradient of trophic state in a coastal area of the Gulf of Thermaikos (Aegean Sea).

TL;DR: The distribution of phytoplankton taxa and biomass were recorded to assess their association to environmental variables in the Rio de la Plata, a shallow and highly turbid estuary as mentioned in this paper.

TL;DR: Suspended particulate matter (SPM) and sediments were sampled in the Ob and the Yenisei rivers and the adjacent Kara Sea up to 77°N during the ice-free period in August and September 1997 (only sediments), 1999 and 2000 as mentioned in this paper.

TL;DR: In this paper, the authors present a numerical study of the effects of fluid mud upon the tidal flow in the Amazon shelf and demonstrate that the presence of nearbottom fluid mud layers represent an important factor in the dynamics of the Amazon continental shelf, since reducing the bottom stress and, therefore, lowering the energy dissipation, larger tidal amplitudes are allowed to occur.

TL;DR: In this article, the authors studied flushing time and residence time in a small inlet in Cabrera National Park, Western Mediterranean Sea, in order to study the impact of water transport over biological communities.

TL;DR: In this article, the authors examined dissolved and particulate manganese and barium within the Tillamook Bay estuary over seasonal cycles under a range of river discharge conditions from January to December 1999.

TL;DR: In this paper, the authors applied the QTC View/Impact system to investigate a 9- km 2 area at water depths between 6 and 20m in the outer Weser Estuary (German Bight, southeastern North Sea).

TL;DR: In this paper, a BSi analysis was performed on both surface and core sediments from the Ria de Vigo and gravity core samples (core CGPL00-1) from the adjacent continental shelf.

TL;DR: In this article, it is shown that when allowing the flow to adjust to non-hydrostatic pressure, the growth of the flow due to internal pressure errors may be strongly affected.

TL;DR: In this article, a 2.5-month realistic simulation was performed to investigate the processes of dense water formation and cascading in the Gulf of Thermaikos (North Aegean).

TL;DR: In this article, the role of internal tides in sedimentation and re-suspension of biogenic POM on the Namibian shelf and give rise to stable 500-800 km long shore alternating bands of high and low POM concentrations was investigated.

TL;DR: In this paper, the authors report on the first study to explicitly assess the impact of seismic prospecting on shrimp resources, finding that shrimp stocks are resilient to the disturbance by air-guns under their experimental conditions.
