Due to the lapse in federal government funding, NASA is not updating this website. We sincerely regret this inconvenience.
A sphere with three ocean waves in differing shades of blue. Next to the sphere, there is the bolded text "Ocean Color". Under that, there are two acronyms, separated by a vertical pipe: OB.DAAC (Ocean Biology Distributed Active Archive Center) and OBPG (Ocean Biology Processing Group). Lorem ipsum dolor sit amet
