Enhanced ventilation of Eastern North Atlantic Oxygen Minimum Zone with deglacial slowdown of Meridional Overturning

Nature Communications
The 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 ...

Biogeography of Cyanobacterial isiA Genes and Their Link to Iron Availability in the Ocean

Frontiers in Microbiology, 2019
The cyanobacterial iron-stress-inducible isiA gene encodes a chlorophyll-binding protein that provides flexibility in photosynthetic strategy enabling cells to acclimate to low iron availability.

Northwestern Pacific Oceanic circulation shaped by ENSO

Scientific Reports
The intricate currents of the Northwest Pacific Ocean, with strong manifestations along the westside rim, connect tropical and subtropical gyres and significantly influence East Asian and global climates.

Efficient biological carbon export to the mesopelagic ocean induced by submesoscale fronts

Nature Communications
Oceanic submesoscale processes are ubiquitous in the North Pacific Subtropical Gyre (NPSG), where the biological carbon pump is generally ineffective.

Atmospheric wind energization of ocean weather

Nature Communications
Ocean 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.

The Milankovitch Theory Revisited to Explain the Mid-Pleistocene and Early Quaternary Transitions

Atmosphere
The theory of orbital forcing as formulated by Milankovitch involves the mediation by the advance (retreat) of ice sheets and the resulting variations in terrestrial albedo. This approach poses a major problem: that of the period of glacial cycles, which

Nature of Plastic Marine Pollution in the Subtropical Gyres

, 2016
The abundance and distribution of plastic debris in the marine environment show patterns of near- and offshore generation, migration toward and accumulation in the subtropical gyres, fragmentation, and redistribution globally. Ecological impacts in the subtropical gyres include invasive species transport and rampant ingestion and entanglement; yet ...

Impact of Increased Horizontal Resolution of an Ocean Model on Carbon Circulation in the North Pacific Ocean

Journal of Advances in Modeling Earth Systems
The impact of resolving western boundary currents and mesoscale eddies on a carbon circulation simulation for the North Pacific Ocean is investigated to evaluate the merits of using high‐resolution ocean biogeochemical models for climate projections ...
