Sea Surface Salinity Trends over Fifty Years Within the Subtropical North Atlantic
Sea Surface Salinity Trends over Fifty Years Subtropical North Atlantic
2015/7/20
Seawater is a dilute salt solution. The salt or salinity is reduced or elevated as freshwater is added or removed, respectively, through precipitation, evaporation, and sea-ice melting and freezing, a...
Regional Differences in the Role of Eddy Pumping in the North Atlantic Subtropical Gyre: Historical Conundrums Revisited
Eddy Pumping Historical Conundrums Revisited
2015/7/20
The vast subtropical regions of the ocean account for at least 30% of the carbon export to the deep ocean. It is predicted that these regions will get larger as a consequence of global warming. Tradit...
The Wintertime Subtropical Current in the Northwestern Pacific
Northwestern Pacific Wintertime Subtropical Current
2015/7/16
The strong wintertime westward current in the northwestern Pacific between 18°N and 23°N was investigated using data from satellite-tracked drifters. The decadal strengthening of the negative wind str...
Transformation and fate of microphytobenthos carbon in subtropical shallow subtidal sands: A 13C-labeling study
Transformation fate of microphytobenthos carbon subtropical shallow subtidal sands A 13C-labeling study
2014/4/2
Microphytobenthos (MPB) in photic sediments are highly productive but the fate of this production remains uncertain. Over 33 d, tracing of 13C from added bicarbonate in subtropical shallow subtidal sa...
Midwater zooplankton and suspended particle dynamics in the North Pacific Subtropical Gyre: A stable isotope perspective
North Pacific Subtropical Gyre Midwater zooplankton
2014/4/2
We used amino acid (AA) compound-specific isotope analysis (d15NAA and d13
CAA values) of midwater
zooplankton and suspended particles to examine their dynamics in the mesopelagic zone. Suspended pa...

2014/4/4
Microphytobenthos (MPB) in photic sediments are highly productive but the fate of this production remains uncertain. Over 33 d, tracing of 13C from added bicarbonate in subtropical shallow subtidal sa...
Characterization of alkaline phosphatase activity in the North and South Pacific Subtropical Gyres: Implications for phosphorus cycling
alkaline phosphatase activity iin the North South Pacific Subtropical Gyres:phosphorus cycling
2014/4/8
We characterized alkaline phosphatase (AP) activity (APA) and report AP kinetic parameters in the North and South Pacific Subtropical Gyres (NPSG and SPSG, respectively) to evaluate the relative impor...
Latitudinal distribution of diazotrophs and their nitrogen fixation in the tropical and subtropical western North Pacific
Latitudinal distribution diazotrophs nitrogen fixation the tropical subtropical western North Pacific
2014/4/18
Latitudinal distribution of diazotrophs and their nitrogen (N2) fixation activity were investigated in the western North Pacific in winter (Nov to Dec 2004) and summer (May to Jun 2005) along meridion...

2014/4/18
We used longline fishing to determine the effects of distance from the ocean, season, and short-term variation in abiotic conditions on the abundance of juvenile bull sharks (Carcharhinus leucas) in a...
Multidecadal climate oscillations detected in a transparency record from a subtropical Florida lake
Multidecadal climate oscillations transparency record subtropical Florida lake
2014/4/17
Synchronous interannual variability in water transparency observed in neighboring lakes has been linked to regional precipitation and resultant runoff of dissolved organic material, but many climate f...
