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...

Alkaline phosphatase activity regulation the North Pacific Subtropical Gyre
2014/4/17
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 (+...
Quantification of zooplankton trophic position in the North Pacific Subtropical Gyre using stable nitrogen isotopes
zooplankton trophic position North Pacific Subtropical Gyre
2014/4/17
We quantify the trophic positions of subtropical open-ocean zooplankton species using amino acid–specific
(AA) stable nitrogen isotopic compositions. We model animal trophic position by computing tro...
Low-Frequency Eddy Variability at 28°N, 152°W in the Eastern North Pacific Subtropical Gyre
