Shown here are objective maps of the Scanfish data
obtained from the average profiles, which were generated
by averaging each complete dive cycle of the undulating
Scanfish path into one profile with 2m vertical bins. 
The average position of the profiles is indicated by
asterisks in the map. The shorter dive cycle on the shallower
shelf produced denser profile spacing.

The objective map grid spacing is 0.02 degrees in longitude
and latitude, between -73.3 and -72.6 degrees longitude and
38.8 and 39.4 degrees longitude, respectivly. Two-dimensional
maps were generated over 2m intervals between between 2m and 120m.

The correlation scale was assumed to be 10km in both longitude
and latitude.

The "error_level" in generating the map was set to 0.1
(variable "err_lvl"); for the plots, a blanking based on the
error map excludes areas exceeding 0.4.
