Today’s Image of the Day comes thanks to the NASA Earth Observatory and features a look at a spring phytoplankton bloom in the Gulf of Alaska.
This photo was taken on April 12, 2017 by the Moderate Resolution Spectroradiometer (MODIS) onboard NASA’s Aqua satellite.
This phenomenon occurs when bedrock that has been ground into dust by glaciers seeps into the water and turns it a turquoise color. It also promotes the growth of phytoplankton that feed off its iron.
“We generally expect the blooms to start inshore and then propagate out to deeper water as stratification takes place,” said Scott Pegau, researcher at the Prince William Sound Science Center.
