Scientists from the National Oceanic and Atmospheric Administration (NOAA) are returning to Alaska´s Kachemak Bay in August to continue part two of a large-scale project called Hydropalooza to map Kachemak Bay´s seafloor and coastline. Teams will be working from ships, aircraft, and land, to bring Alaskans accurate data used to support safe maritime transportation, protect coastal communities, assess fisheries and critical marine habitats, and better understand the Bay. Learn about the ocean and coastal operations taking place on the land, in the sea, and above the horizon ­ and how mapping data can be used by so many people for so many different purposes here.
