We analyzed long-term (5–8 yr) hourly time series of chlorophyll (Chl) converted from fluorescence measurements in relation to discharge and light in three medium- to large-size rivers, where plankton...
Eddy growth and mixing in mesoscale oceanographic flows
Eddy growth and mixing mesoscale oceanographic flows
font style='font-size:12px;'>
2009/11/13
We study the relation between changes in the Eulerian topology of a two dimensional flow and the mixing of fluid particles between qualitatively different regions of the flow. In general time dependen...
Detecting unstable structures and controlling error growth by assimilation of standard and adaptive observations in a primitive equation ocean model

Oceanic and atmospheric prediction is based on cyclic analysis-forecast systems that assimilate new observations as they become available. In such observationally forced systems, errors amplify depend...
A Model for the Thermodynamic Growth of Sea Ice in Numerical Investigations of Climate
Thermodynamic Growth Numerical Investigations of Climate Sea Ice
font style='font-size:12px;'>
2009/3/7
A model is presented whereby the thickness and extent of sea ice may be predicted in climate simulations. A basic one-dimensional diffusion process is taken to act in the ice, with modifications due t...

2009/2/16
Immediately following the passage of polar fronts that produced strong winds blowing away from Galveston Island and into the Gulf of Mexico, we used scattered LORAN-A radio waves, together with observ...
Temporal Rates of Growth and Decay of Microscopic and Macroscopic Surface Structures in a Wind-Wave Tank
Temporal Rates Macroscopic Surface Structures Wind-Wave Tank
font style='font-size:12px;'>
2009/2/13
The distributions of water-surface slopes and wave heights were measured under suddenly started and stopped winds. The root-mean-square slopes and average wave heights are found to grow and decay expo...
A Study of the Growth of the Wave Spectrum with Fetch
Wave Spectrum fetch consecutive wave buoys
font style='font-size:12px;'>
2009/2/10
The development of the wave spectrum with fetch in a steady wind has been studied with a line of consecutive wave buoys in the Bothnian Sea in 1976 and 1979. The relationship that was found between di...
