SURFACE CHLOROPHYLL-A TIME SERIES IN CENTRAL PRINCE WILLIAM SOUND. DATA ARE DAILY MEAN AND STANDARD DEVIATION WITHIN NON-CLOUD-MASKED PIXELS. THE SEAWIFS AND MODIS DATA WERE EXAMINED FOR AN OFFSET BETWEEN THE TWO DURING YEARS WHEN THE TWO TIME SERIES OVERLAPPED (2003-2010). SEAWIFS CHLOROPHYLL ESTIMATES TENDED TO BE SLIGHTLY LOWER THAN MODIS ESTIMATES AND WERE ADJUSTED TO MAKE THE ESTIMATES COMPARABLE. DATA WERE DOWNLOADED FROM THE NOAA COASTWATCH PROGRAM/NASA’S GODDARD SPACE FLIGHT CENTER OCEANCOLOR WEB (HTTPS://COASTWATCH.PFEG.NOAA.GOV/ERDDAP/GRIDDAP/INDEX.HTML; DATA PRODUCTS ERDMBCHLA1DAY AND ERDSW2018CHLA1DAY).
