Variability of subsurface denitrification and surface productivity in the coastal eastern Arabian Sea over the past seven centuries

Ocean–Atmosphere Covariability in the Western Arabian Sea*

The western Arabian Sea exhibits strong spatial variability in sea surface temperature (SST) during the southwest monsoon, with changes in SST that can exceed 58C over 200 km. Exploration of satellite-based and in situ data shows a strong connection between mesoscale SST features and changes in the atmospheric boundary layer. The fundamental relationship is that of weak (strong) wind velocities...

Denitrification effects on air-sea CO2 flux in the coastal ocean: Simulations for the northwest North Atlantic

[1] The contribution of coastal oceans to the global air-sea CO2 flux is poorly quantified due to insufficient availability of observations and inherent variability of physical, biological and chemical processes. We present simulated air-sea CO2 fluxes from a high-resolution biogeochemical model for the North American east coast continental shelves, a region characterized by significant sedimen...

Phytoplankton responses to atmospheric metal deposition in the coastal and open-ocean Sargasso Sea

This study investigated the impact of atmospheric metal deposition on natural phytoplankton communities at open-ocean and coastal sites in the Sargasso Sea during the spring bloom. Locally collected aerosols with different metal contents were added to natural phytoplankton assemblages from each site, and changes in nitrate, dissolved metal concentration, and phytoplankton abundance and carbon c...
