Dive thru the Portal

Marvels lie under the sea

Right here on the ocean floor
Such wonderful things surround you

     –The Little Mermaid: Under the Sea

Thousands of photos and videos of the seafloor, its creatures and the coastline — most areas never seen before — are now just a mouse-click away, thanks to the U.S. Geological Survey Coastal and Marine Geology Video and Photograph Portal.
    The Portal is a treat for you and me and a great help for coastal managers faced with decisions from protecting habitats to understanding hazards and managing land use.
    The largest database of its kind, it delivers detailed, fine-scale representations of the coast plus maps of the exact location of each recording.
    A work in progress, the Portal so far covers the seafloor off California and Massachusetts with aerial images of the Gulf of Mexico and Mid-Atlantic coastlines.
    Some 100,000 photographs have been collected along with 1,000 hours of trackline video covering 2,000 miles of coastline.
    Upcoming are Washington State’s Puget Sound, Hawaii and the Arctic.
