Methods
~2 minute grid, smoothed version of the USGS 15 second bathymetric grid (from K.
Smith, WHOI)
Objective analysis for 12 months (calculated for the 15th of each month)
nine z-layers (1m-10m-20m-30m-40m-50m-100m-150m-200m)
calculated as z ±5 (0-5, 5-15, 15-25, 25-35, 35-45, 45-55, 95-105, 145-155, 195-205)
Computed based on relative weightings of x, y, z, date, Temperature, Salinity, and
log(bathymetry) to retain some separation across frontal zones and along the
shallower contours
Gaussian weighting function for all parameters; standard deviations for each
x,y=50km,
z=10m,
date=30 days
Temperature=2.5°C,
Salinity=.5 psu,
Log bathymetry=.5,
