On Wind‐Driven Energetics of Subtropical Gyres
Journal of Advances in Modeling Earth Systems, 2021 The flow of energy in the wind‐driven circulation is examined in a combined theoretical and numerical study. Based on a multiple‐scale analysis, we find the mesoscale field in the ocean interior is strongly affected by, but does not feed back onto, the ...

Geophysical Research Letters, 2023 The mechanism that determines the dynamics of subsurface chlorophyll maximum depth (zSCM) has long been debated. Although a coupling between zSCM and the top of nitracline (znit) has been widely observed in the open ocean, a co‐location of zSCM and an ...

Overturning cells in the Southern Ocean and subtropical gyres [PDF]
Ocean Science, 2007 The circulation of the subtropical gyres can be decomposed into a horizontal recirculation along contours of constant Bernoulli potential and an overturning circulation across these contours.

Asynchronous Poleward Migration of the Atlantic Subtropical Gyres Over the Past 22,000 years
Geophysical Research LettersBy exchanging huge amounts of heat between the tropics and high latitudes, subtropical gyres significantly impact Earth's energy balance. Yet, their dynamical changes during the last deglaciation remain poorly understood.

Phytoplankton growth rates in the Atlantic subtropical gyres [PDF]
Limnology and Oceanography, 2005 Reported estimates of phytoplankton growth rate (m) in the subtropical gyres range widely from 0.1-0.2 to 1-2 d 21 . Dividing chlorophyll a (Chl a)-normalized photosynthesis (P B ) and .40 determinations of phytoplankton C : Chl a obtained in surface waters of the eastern North Atlantic Subtropical Gyre (NAST-E), the western NAST (NAST-W), and the ...

The sensitivity of the Eocene–Oligocene Southern Ocean to the strength and position of wind stress [PDF]
Climate of the Past, 2022 The early Cenozoic opening of the Tasmanian Gateway (TG) and Drake Passage (DP), alongside the synergistic action of the westerly winds, led to a Southern Ocean transition from large, subpolar gyres to the onset of the Antarctic Circumpolar Current (ACC).

The downward spiralling nature of the North Atlantic Subtropical Gyre [PDF]
Nature Communications, 2022 AbstractThe Atlantic Meridional Overturning Circulation (AMOC) regulates the heat distribution and climate of Earth. Here we identify a new feature of the circulation within the North Atlantic Subtropical Gyre that is associated with the northward flowing component of the AMOC.

Meridional changes in the South Atlantic Subtropical Gyre during Heinrich Stadials
Scientific Reports, 2021 Subtropical ocean gyres play a key role in modulating the global climate system redistributing energy between low and high latitudes. A poleward displacement of the subtropical gyres has been observed over the last decades, but the lack of long-term ...

Microstructure and composition of marine aggregates as co-determinants for vertical particulate organic carbon transfer in the global ocean [PDF]
Biogeosciences, 2020 Marine aggregates are the vector for biogenically bound carbon and nutrients from the euphotic zone to the interior of the oceans. To improve the representation of this biological carbon pump in the global biogeochemical HAMburg Ocean Carbon Cycle ...
