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 ...
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...

Pelagic food webs drive a flux of .10 31012
kg C yr21
that exits surface waters, mostly via sinking particles
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...
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 with a Barotropic Open Ocean Model
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 Momentum Flux Measurements in Moderate to Strong Winds
Ocean Momentum Flux Measurements Strong Winds
2009/2/9
Measurements of the momentum flux were made by the Reynolds flux and dissipation methods on a deep water stable tower operated by the Bedford Institute of Oceanography, A modified Gill propeller-vane ...
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...
Estimation of Low-Frequency Wind Stress Fluctuations over the Open Ocean
Low-Frequency Wind Stress Fluctuations Open Ocean
2009/2/5
A simple, approximate formula for mean wind stress is given in terms of the mean and variance of the wind fluctuations over the averaging period. The formula is nonlinear with respect to the mean wind...
Pressure Fluctuations on the Open-Ocean Floor off the Gulf of California：Tides, Earthquakes, Tsunamis
Pressure Fluctuations Tides Earthquakes Tsunamis Open-Ocean Floor
2009/2/5
This paper supplements an initial article on sea-floor pressure observations conducted with a sensitive though not “perfectly” stable transducer. A variety of examples are used to demonstrate that a w...
Steady wind-drift currents in a deep viscous rotating ocean are studied theoretically. The analysis is based on the Lagrangian description of motion.
A mean wind-stress at the surface yields the tr...
