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...
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 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...
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...
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...
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...
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 (N2) fixation activity were investigated in the western North Pacific in winter (Nov to Dec 2004) and summer (May to Jun 2005) along meridion...
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...
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...
The North Pacific subarcticsubtropical boundary region is an important sink for atmospheric CO2 , with high annual influx relative to surrounding waters and large seasonal variability. The location...
Alkaline phosphatase (AP) activity (APA) was measured at several stations in the North Pacific Subtropical Gyre in July 2008, and in a series of nutrient addition experiments: nitrate plus ammonium (+...
The composition and production of carbohydrates (mannose, rhamnose, fucose, galactose, glucose, and xylose) and their transfer among sediment compartments (microphytobenthos [MPB], bacteria, and detri...
The effect of oceanic eddies on microbial processes, with emphasis on bacterial losses due to protists and phages, was examined in the Canary Current region (subtropical northeast Atlantic) through t...
We used high-frequency in situ measurements of nitrate (NO{ 3 ) and dissolved oxygen (DO) from the springfed Ichetucknee River, Florida, to derive multiple independent estimates of assimilatory nitr...
