9 June 1998 Level 2

Level-2 SeaWiFS Image from day 160 (9 June 1998) processed from Level-1A data obtained from the GSFC DAAC courtesy Bedford Institute of Oceanography. This image covers approximately 40-50N and 25-50W.

9 June 1998 Level 3

Level-3 SeaWiFS Image also from day 160 extracted and cropped from the level-3 binned data. This image covers approximately 35-55N and 20-55W.

Slide 7

Comparison of semivariograms for high resolution (level 2) and low resolution (level 3) satellite ocean chlorophyll for the region 30-35W, 45-50N for June 1998 in the north-south and east-west directions to demonstrate anisotropy. Spherical model parameters were estimated using non-linear least squares.

Slide 8

Semivariograms displaying non-stationarity for June 1998. Each panel shows the semivariogram values versus distance in the north-south direction in a region located 30-35W, the latitude changes from panel to panel.
