Grazing and Zooplankton Production as Key Controls of Phytoplankton Production in the Open Ocean
Coast phytoplankton pigment waters physical oceanography
2015/8/17
Thanks to NASA's Coastal Zone Color Scanner (CZCS, 1978-1986), nearly ocean-wide coverage of the distribution of phytoplankton pigment in the upper part of the euphotic zone and, in effect, in the mix...
Oxygen Concentrations and Biological Fluxes in the Open Ocean
Oxygen Concentrations Biological Fluxes Open Ocean
2015/7/17
The oxygen concentration in the ocean is controlled by a delicate balance between the source from atmosphere-ocean interaction and net respiration of organic matter after the water leaves the surface ...
An open ocean record of the Toarcian oceanic anoxic event
ocean record Toarcian oceanic anoxic event
2014/12/31
Oceanic anoxic events were time intervals in the Mesozoic characterized by widespread distribution of marine organic matter-rich sediments (black shales) and significant perturbations in the global ca...
At different times of the year, prevailing winds blow into Bermuda from open ocean to the south or from the continental United States — an ideal laboratory for studying pollution generated by human ac...
Environmental control of open-ocean phytoplankton groups: Now and in the future
Environmental control open-ocean phytoplankton groups Now and in the future
2014/4/17
Climate change will alter concurrently many environmental factors that exert control over oceanic phytoplankton. Recent laboratory culture work, shipboard experiments, and field surveys reveal many re...
On the representativeness of coastal aerosol studies to open ocean studies: Mace Head – a case study

Measurements of Momentum and Sensible Heat Fluxes Over the Open Ocean
Floating Instrument Platform Sensible Heat Fluxes Barbados Oceanographic and Meteorological Experiment
2009/4/2
Vertical fluxes of momentum and sensible heat have been measured above the sea surface by the direct dissipation method. Measurements were made over the open ocean from the Scripps Floating Instrument...
Baroclinic instability is examined in a two-layer, quasi-geostrophic model for linearized mesoscale waves (i.e., with periods of a few months and length scales near the internal deformation radius). T...
Open ocean DMS air/sea fluxes over the eastern South Pacific Ocean
Open ocean DMS air/sea eastern South Pacific Ocean
