These raster images are seasonal composites, and were calculated as means or as medians. The seasons were defined as the following: 1) Fall= September, October, November; 2) Winter= December, January, February; 3) Spring= March, April, May; 4) Summer= June, July, August. For example, June '98, July '98, August '98 = Chlorophyll Summer '98. These images were also reprocessed to remove land and no data values (value = 252 and value = 0, 253, 251 respectively), as well as to calculate the real world values for chlorophyll in micrograms per liter. These data were obtained and reprocessed to support the biogeographic assessment of Stellwagen Bank National Marine Sanctuary.

CREATING REMOTELY SENSED IMAGES:An EASI program was run on the daily Chlorophyll geotifs of the SeaWiFS northeast region to create Seasonal Average geotifs for the specified region of the Gulf of Maine. These images were created using the following months: Winter= December, January, February Fall= September, October, November Spring= March, April, May Summer= June, July, August. These seasonal average chlorophyll geotifs were used to make grand seasonal Mean images, which consist of the average of all Mean images for each season in the time series.(ex: spring '98, spring '99, spring 00, spring 01, spring 02, spring 03, spring 04 = SW1998200401_GrdSSN_AvgCHL.tif). The new geotifs were reprojected from their original SIN E019 projection to Albers Conic Equal Area,NAD 83, GRS 80. These images are scaled down from 16 bit data to 8 bit data. 2005-01-01T00:00:00 REPROCESS REMOTELY SENSED IMAGERY:These remotely sensed images were reprocessed to remove land and no data values as well as to calculate the real world values for chlorophyll. To do so, a script was written in VB 6.0 and run as a macro in ArcGIS 9.1, which reclassed the land (8 bit value = 252) and no data values (8 bit value = 0, 253 and 251) as no data. A second macro also written in VB 6.0 calculated the real world value of chlorophyll (in micrograms per liter) using the following algorithm:CHL = 10^(((8bit # -1)*(3/250))-1.3)The resulting ERDAS Imagine files were subsequently imported into personal geodatabases. 2006-05-01T00:00:00
