The interplay between bacterial community composition and the environment determining function of inland water bacteria
bacterial community composition the environment determining function inland water bacteria
2014/4/16
We hypothesized that habitats differing in water flow regime would differ in bacterial function either because of differences in the local environment, in bacterial community composition (BCC), or in ...
Determining the Ocean Circulation and Improving the Geoid from Satellite Altimetry
Ocean Circulation Satellite Altimetry
2009/1/15
The combined problem of determining the ocean circulation and improving the geoid from satellite altimetry is formulated and studied. Minimum variance estimation is used to form optimum estimates of t...
A Bernoulli Inverse Method for Determining the Ocean Circulation
Bernoulli Inverse Method Ocean Circulation
2009/1/13
A new inverse method for finding the large-scale ocean circulation is described. Unlike most previous methods it uses no horizontal gradient information, and is designed for widely spaced data. The me...

Interior Mixing Stratification Circulation Air-Sea Fluxes
2009/1/12
The problem of determining the (eastern boundary) basic stratification and the buoyancy-driven circulation of the oceans is addressed. A global integral constraint relating the interior stratification...
Determining the Strength of the Deep Western Boundary Current Using the Chlorofluoromethane Ratio
chloro fluoro methanes Deep Western Boundary Current
2009/1/4
The dilution of a passive tracer during deep water formation and the subsequent advection/mixing in a deep boundary current is modeled with application to chlorofluoromethanes (CFMs) in the North Atla...
Determining Velocities and Mixing Coefficients from Tracers
