A Time-Series View of Changing Ocean Chemistry Due to Ocean Uptake of Anthropogenic CO2 and Ocean Acidification
Time-Series View Changing Ocean Chemistry Due Ocean Uptake Anthropogenic CO2 Ocean Acidification
2015/7/17
Sustained observations provide critically needed data and understanding not only about ocean warming and water cycle reorganization (e.g., salinity changes), ocean eutrophication, and ocean deoxygenat...
Nitrate uptake by foraminifera and use in conjunction with endobionts under anoxic conditions
Nitrate uptake foraminifera endobionts anoxic conditions
2014/10/16
Among eukaryotes, some benthic foraminiferal species have been reported to be capable of nitrate respiration, although little is known about their denitrification processes. In this study, we incubate...
A discrepancy between predictions of saturating nutrient uptake models and nitrogen-to-phosphorus stoichiometry in the surface ocean
saturating nutrient uptake models nitrogen-to-phosphorus stoichiometry the surface ocean
2014/4/17
We derive a simple prediction about euphotic zone N : P stoichiometry from a large class of models that use saturating nutrient uptake functions to characterize N and P acquisition by phytoplankton. T...
Stream denitrification and total nitrate uptake rates measured using a field 15N tracer addition approach
Stream denitrification total nitrate uptake rates field 15N tracer addition approach
2014/5/14
We measured denitrification and total nitrate uptake rates in a small stream (East Fork of Walker Branch in eastern Tennessee) using a new field 15N tracer addition and modeling approach that quantifi...
The uptake of silica during the spring bloom in the Northeast Atlantic Ocean
silica spring bloom Northeast Atlantic Ocean
2014/5/21
A full understanding of the biogeochemical cycling of silica in the North Atlantic is hampered by a lack of estimates of silica uptake by phytoplankton. We applied the 32Si radiotracer incubation tech...
Uptake and efflux of 64 Cu by the marine cyanobacterium Synechococcus (WH7803)
the marine cyanobacterium Synechococcus Uptake
2014/5/20
The uptake and efflux of
64
Cu was studied in the marine cyanobacterium Synechoccous strain WH7803 (DC2).
Uptake followed classical Michaelis-Menten type kinetics in metal-buffered seawater. ...
Peptide hydrolysis, amino acid oxidation, and nitrogen uptake in communities seasonally dominated by Aureococcus anophagefferens
Peptide hydrolysis amino acid oxidation nitrogen uptake communities seasonally Aureococcus anophagefferens
2014/5/27
Elevated levels of dissolved organic nitrogen (DON) and dissolved inorganic nitrogen (DIN) are among the factors implicated in the initiation of algal blooms. However, the degree to which phytoplankto...
