این محصول سطح 3 شامل رنگ اقیانوس و داده های زیست شناسی اقیانوس ماهواره ای است که تحت EOSDIS تولید یا جمع آوری شده است.
این مجموعه داده ممکن است برای مطالعه زیست شناسی و هیدرولوژی مناطق ساحلی، تغییرات در تنوع و توزیع جغرافیایی زیستگاه های دریایی ساحلی، شارهای بیوژئوشیمیایی و تأثیر آنها در اقیانوس ها و آب و هوای زمین در طول زمان، و در نهایت تأثیر تغییرات آب و هوایی و محیطی و تغییرات بر اکوسیستم های اقیانوس و تنوع زیستی آنها مورد استفاده قرار گیرد.
