Welcome to the offsite website for the Ecosystems and Oceanography Division.

Presently residing here are some analyses of ROMS3 physical variables and other older material:

• Comparison of 1990-1998 to 1999-2004 mean fields at depth for temperature, silicate, u, v, w, and salinity from Fei Chai ROMS3 data in the equatorial region.
  
• EOFs of w from Fei Chai ROMS3 model data, 50m, 100m, and 0-100m.
  
• Frequency histograms of Fei Chai ROMS3 w (vertical component of current) over all months of data (1990-2004). Box 1 is Equatorial -20S to 20N, 120E to 80W. Box 2 is California Current 20N to 60N, 140W to 105W.
  
• Time series monthly pixel count of low 25% and high 25% w, temperature, u, and v from Fei Chai ROMS3 data. Box 1 is Equatorial -20S to 20N, 120E to 80W. Box 2 is California Current 20N to 60N, 140W to 105W.
  
• Time series of SUMMED pixel counts, both low and high together.
