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 ...

Ocean’s largest chlorophyll-rich tongue is extending westward (2002–2022) [PDF]
Nature CommunicationsUpwelling in the Equatorial Pacific nurtures an expansive, westward-stretching chlorophyll-rich tongue (CRT), supporting 18% of the annual global new production. Surrounding the CRT are the oligotrophic subtropical gyres to the north and south, which are

Genomic and metabolic diversity of Marine Group I Thaumarchaeota in the mesopelagic of two subtropical gyres. [PDF]
PLoS ONE, 2014 Marine Group I (MGI) Thaumarchaeota are one of the most abundant and cosmopolitan chemoautotrophs within the global dark ocean. To date, no representatives of this archaeal group retrieved from the dark ocean have been successfully cultured.

Enhanced ventilation of Eastern North Atlantic Oxygen Minimum Zone with deglacial slowdown of Meridional Overturning [PDF]
Nature CommunicationsThe eastern Tropical North Atlantic Oxygen Minimum Zone (ETNA OMZ) plays a critical role in marine ecosystems off northwestern Africa. One of the key controls of the ETNA OMZ is ventilation driven by the subsurface ocean circulation of the Atlantic ...

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.

Global Drivers of Phytoplankton Phenology Trends. [PDF]
Glob Chang BiolObservations and a global biogeochemical model were used to examine recent shifts in phytoplankton phenology at the global scale. Sea surface temperature trends emerge as the strongest predictor of these changes, relative to the other drivers considered, and are associated with earlier initiation, later termination, and longer growing periods ...

Atmospheric wind energization of ocean weather [PDF]
Nature CommunicationsOcean weather comprises vortical and straining mesoscale motions, which play fundamentally different roles in the ocean circulation and climate system. Vorticity determines the movement of major ocean currents and gyres.
