Larval Transport and Coastal Upwelling: An Application of HF Radar in Ecological Research
Larval Transport Coastal Upwelling HF Radar Ecological Research
2015/8/10
For many marine fish and invertebrate species, near-surface currents strongly affect the likelihood of surviving as a planktonic larva and arriving at a suitable location, say, a rocky coastline, a ke...

During the lifetime of the National Science Foundation's Coastal Ocean Processes program, four experiments were conducted on the US West Coast in the northern California Current System. Although each ...
Global warming to increase ocean upwelling, but fisheries impact uncertain
Global warming increase ocean upwelling fisheries impact uncertain
2015/3/4
A report to be published Thursday in the journal Nature suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at ...
Nutrient dynamics and biological consumption in a large continental shelf system under the influence of both a river plume and coastal upwelling
Nutrient dynamics biological consumption large continental shelf system influence of both a river plume coastal upwelling
2014/4/4
We examined the dynamics of dissolved inorganic nitrogen (DIN, nitrate + nitrite), dissolved inorganic phosphorus (DIP), and silicate (Si(OH)4) in the northern shelf of the South China Sea in summer, ...

2014/4/17
We investigate a range of indices to quantify upwelling on the central Great Barrier Reef (GBR), Australia, so
that environmental and biological relationships associated with upwelling in this area c...
Upwelling couples chemical and biological dynamics across the littoral and pelagic zones of Lake Tanganyika, East Africa
Upwelling couples chemical biological dynamics littoral and pelagic zones Lake Tanganyika East Africa
2014/4/16
We studied the effects of upwelling on nutrient and phytoplankton dynamics in the pelagic and littoral zones of Lake Tanganyika near Kigoma, Tanzania. During the dry season of 2004, a rise in the ther...
The relative importance of microbial and classical food webs in a highly productive coastal upwelling area
microbial classical food webs highly productive coastal upwelling area
2014/4/22
We present an analysis of seasonal variations in the trophic pathways of carbon in a highly productive coastal upwelling region in the Humboldt current system off Chile. Seasonal changes in phytoplank...
Microbial and photochemical reactivity of fluorescent dissolved organic matter in a coastal upwelling system
Microbial and photochemical reactivity fluorescent dissolved organic matter coastal upwelling system
2014/5/4
We observed significant changes in the dissolved oxygen content and the fluorescence of humic substances and dissolved aromatic amino acids after 24 h light and dark incubations in the coastal upwelli...
Production of cobalt binding ligands in a Synechococcus feature at the Costa Rica upwelling dome
cobalt binding ligands Synechococcus feature Costa Rica upwelling dome
2014/5/8
The Costa Rica upwelling dome (CRD; ~8.67°N and 90.6°W) was characterized chemically for cobalt and nickel abundances and speciation and biologically using cyanobacterial abundances and phylogeny. Tot...
The interplay between upwelling and deep convective mixing in determining the seasonal phytoplankton dynamics in the Gulf of Aqaba: Evidence from SeaWiFS and MODIS
upwelling deep convective mixing seasonal phytoplankton dynamics the Gulf of Aqaba SeaWiFS and MODIS
2014/5/22
In the Gulf of Aqaba, the northeasternmost segment of the Red Sea, phytoplankton blooms are more intense than in other oligotrophic regions (e.g., the Sargasso Sea). In this study, we use multiyear in...
Effects of optically shallow bottoms on upwelling radiances: Bidirectional reflectance distribution function effects
optically shallow bottoms upwelling radiances Bidirectional reflectance distribution function effects
2014/5/19
Radiative transfer simulations were carried out for a variety of measured and modeled benthic bidirectional reflectance distribution functions (BRDFs), incident lighting conditions, bottom depths, and...
Effects of optically shallow bottoms on upwelling radiances: Inhomogeneous and sloping bottoms
optically shallow bottoms upwelling radiances Inhomogeneous and sloping bottoms
2014/5/19
If the benthic boundary in optically shallow waters is spatially inhomogeneous or sloping, the underwater light field is inherently three-dimensional (3D). Numerical simulations of 3D underwater radia...
