Particle Flux in the Deep Sargasso Sea:The 35-Year Oceanic Flux Program Time Series
Particle Flux Deep Sargasso Sea 35-Year Oceanic Flux Program Time Series
2015/7/17
The Oceanic Flux Program (OFP) sediment trap time series, the longest running time series of its kind, has continuously measured particle fluxes in the deep Sargasso Sea since 1978. OFP results provid...
Floating tar balls are a product of weathering of crude oil in the marine environment. They have been found to be prevalent in the world ocean, particularly in the 1960s and 1970s before stricter cont...
Dispersal pathways of American eel larvae from the Sargasso Sea
merican eel larvae Sargasso Sea
2014/10/16
At the end of their life cycle, American eel (Anguilla rostrata) migrate to the Sargasso Sea from freshwater
habitats along the east coast of North America in order to spawn planktonic eggs. The eggs...
Dissolved inorganic and organic phosphorus uptake inTrichodesmiumand the microbial community: The importance of phosphorus ester in the Sargasso Sea
Dissolved inorganic organic phosphorus uptake Trichodes mium microbial community phosphorus ester the Sargasso Sea
2014/4/17
The dynamics and relative importance of inorganic phosphate (Pi) and dissolved organic phosphorus (DOP) uptake were examined inTrichodesmiumand the microbial community.Trichodesmium DOP and Pi uptake ...
Polyphosphate inTrichodesmiumfrom the low-phosphorus Sargasso Sea
Polyphosphate Trichodesmium the low-phosphorus Sargasso Sea
2014/4/16
Polyphosphate (polyP) is often considered to be the product of luxury uptake in areas of excess phosphorus(P), but can also accumulate in P-depleted cells in response to P resupply. To test the hypoth...
Production, dissolution, accumulation, and potential export of biogenic silica in a Sargasso Sea mode-water eddy
Production dissolution accumulation
2014/4/16
Rates of biogenic silica (bSiO2) production, dissolution, accumulation, and potential bSiO2 export were
determined in a Sargasso Sea mode-water eddy (MWE) during two occupations in April 2007. Standi...
Diel carbon monoxide cycling in the upper Sargasso Sea near Bermuda at the onset of spring and in midsummer
Diel carbon monoxide cycling the upper Sargasso Sea Bermuda spring in midsummer
2014/4/21
Rapid bio-oxidation of carbon monoxide (CO), a photoproduct of dissolvedorganic matter, results in diel cycles reflecting photochemical–biogeochemical–physical interactions. These cycles were characte...
Biological CO oxidation in the Sargasso Sea and in Vineyard Sound, Massachusetts
Biological CO oxidation Sargasso Sea Vineyard Sound Massachusetts
2014/5/9
In situ dissolved carbon monoxide (CO) in oligotrophic waters follows a diel cycle varying from 0.3 to 0.5 nmol L-1 before dawn to 2.5 to 3 nmol L-1 in early afternoon, when photo-production of CO exc...
Taxonomic variability of phosphorus stress in Sargasso Sea phytoplankton
Taxonomic variability phosphorus stressLSargasso Sea phytoplankton
2014/5/19
Low inorganic phosphorus (SRP) concentrations and high inorganic nitrogen to phosphorus ratios suggest that phytoplankton production in the northwestern Sargasso Sea may be controlled to some extent b...
Interactions between DOC, microbial processes, and community structure in the mesopelagic zone of the northwestern Sargasso Sea
DOC microbial processes community structure mesopelagic zone the northwestern Sargasso Sea
2014/5/19
At the Bermuda Atlantic Time-Series Study (BATS) site, the field observations of dissolved organic carbon (DOC) dynamics indicate that seasonally produced ‘‘semilabile’’ DOC is res...
Sources and cycling of carbonyl sulfide in the Sargasso Sea
Sources and cycling carbonyl sulfide Sargasso Sea
2014/5/14
The cycling of the radiatively important gas carbonyl sulfide (OCS) was studied in surface waters of the Sargasso Sea. In August 1999, surface OCS concentrations averaged 8.6 pmol L-1, showed minor di...

Photolysis dimethyl sulfide summer paradox Sargasso Sea
2014/5/20
Apparent quantum yields and rates of dimethylsulfide (DMS) photolysis were determined from Sargasso Sea seawater with the goal of assessing the extent to which photoreactions affect the unusually elev...

Copper toxicity cyanobacteria ecology Sargasso Sea
2014/5/27
The closely related cyanobacteria Synechococcus and Prochlorococcus have different distributions in stratified water columns in the northern Sargasso Sea. The abundance of Synechococcus is relatively ...
