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...
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
representativeness coastal aerosol Mace Head
2009/12/31
A unique opportunity arose during the MAP project to compare open ocean aerosol measurements with those undertaken at the Mace Head Global Atmosphere Watch Station, a station used for decades for aero...

Significant contribution large particles optical backscattering open ocean
2010/1/20
The light scattering properties of oceanic particles have been suggested as an alternative index of phytoplankton biomass than chlorophyll-a concentration (chl-a), with the benefit of being less sensi...

through the ocean’s ‘‘biological pump.’’ Much of this particle flux is remineralized in...
Experimental Determination of the Eddy Diffusion Coefficient Over the Open Ocean from Atmospheric Electric Measurements
Experimental Determination Eddy Diffusion Coefficient Atmospheric Electric Measurements
2009/4/3
The method of determining the eddy diffusivity over the open ocean either from profiles of the average electric filed or from average values of space charge and electric field measured near the sea su...
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
2009/3/12
Air/sea fluxes of dimethylsulfide (DMS) were measured by eddy correlation over the Eastern South Pacific Ocean during January 2006. The cruise track extended from Manzanillo, Mexico, along 110° W, to ...
Pressure Fluctuations on the Open Ocean Floor Over a Broad Frequency Range：New Program and Early Results
Pressure Fluctuations Broad Frequency Range Open Ocean Floor
2009/2/19
A two-month ocean-floor pressure record obtained 330 km to the east of the main island of Hawaii by means of a Bourdon tube-type transducer with optical readout is discussed in detail. An approach to ...

Dynamical Forecast Experiments Barotropic Open Ocean Model
2009/2/19
The initial/boundary value problem for the barotropic version of a quasi-geostrophic open ocean model which requires normal flow everywhere on the boundary and vorticity on the inflow is studied. Para...

Open Ocean Modeling as an Inverse Problem：Tidal Theory
Open Ocean Modeling Inverse Problem Tidal Theory
2009/2/8
Classical models of tides in open coastal regions employ ad hoc conditions on the open boundaries instead of reliable sea level data on the coastline in order to achieve a well-posed problem. A weight...
