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...
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 and regulation in the North Pacific Subtropical Gyre
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...
Four Views of a Portion of the North Atlantic Subtropical Gyre
North Atlantic Subtropical Gyre β-triangle
2009/2/5
Data from four cruises to the “β-triangle” centered at 27°N, 32°30′W were smoothed by fitting second-degree polynomials at each of about 30 different density surfaces. The density intervals were Δσp=0...
Cross-Gyre Ventilation of the Subtropical Gyre：An Internal Mode in the Ventilated Thermocline
Cross-Gyre Ventilation Ventilated Thermocline Subtropical Gyre
2009/1/20
A model of cross-gyre geostrophic flow is presented. It is a two-layer model of the (Northern Hemisphere) subtropical thermocline above a resting lower ocean. The northern boundary of the gyre is take...
A Synoptic and Statistical Description of the Gulf Stream and Subtropical Gyre Using SOFAR Floats
Gulf Stream Subtropical Gyre SOFAR Floats
2009/1/19
Trajectories of 17 SOFAR floats ballasted to nominal depth of 700 and 2000 m and tracked for 15 months have been analyzed to produce synoptic and statistical descriptions of the Gulf Stream and subtro...
On the Role of Heat Flux in the Gulf Stream-Sargasso Sea Subtropical Gyre System
potential vorticity Heat Flux Gulf Stream-Sargasso Sea Subtropical Gyre System
2009/1/9
In contrast with the traditional view of midlatitude circulation driven by winds in the ocean interior and regulated by friction along the western boundary, it is hypothesized that some control can be...
Low-Frequency Eddy Variability at 28°N, 152°W in the Eastern North Pacific Subtropical Gyre
Low-Frequency Eastern North Pacific Subtropical Gyre Eddy Variability
2009/1/6
A current meter mooring maintained for over three years at 28°N, 152°W, in the eastern North Pacific has yielded velocity and temperature data throughout the water column, with particularly good therm...
An Isopycnic Model Study of the North Atlantic. Part II：Interdecadal Variability of the Subtropical Gyre
Isopycnic Model Study Interdecadal Variability North Atlantic Subtropical Gyre
2008/12/12
In a companion paper, a spinup integration of the North Atlantic Ocean with the Miami isopycnic-coordinate model was presented. The wintertime mixed layer in the central North Atlantic was subject to ...
Observations of Variability in the South Pacific Subtropical Gyre
South Pacific Subtropical Gyre Variability surface transport
2008/12/11
Variability of the subtropical gyre in the South Pacific Ocean was investigated using high-resolution expendable bathythermograph sections along a repeated track between New Zealand and Hawaii. The so...
An Intercomparison of a Bryan-Cox-Type Ocean Model and an Isopycnic Ocean Model. Part II：The Subtropical Gyre and Meridional Heat Transport
Atlantic Isopycnic Model Bryan-Cox-Type Ocean Model Isopycnic Ocean Model
2008/12/10
In a companion paper, two ocean general circulation models were implemented in order to simulate and intercompare the main features of the North Atlantic circulation: the Atlantic Isopycnic Model (AIM...
