Images: Seafloor Reconnaissance Reveals Hidden Dangers Off Antarctica

Greg Packard, in an inflatable boat, prepares to launch an autonomous underwater vehicle called REMUS (Remote Environmental Monitoring UnitS), to measure ocean- bottom depths in a pre-determined area and pattern around Palmer Station, part of a 5-week survey resulting in a new chart of the area.

Several inflatable boats were used during the seafloor survey and needed to be taken out of the water almost daily to avoid ice damage. The Laurence Gould is in the background. (Photo by Keith von der Heydt, WHOI)

A computer generated map of the seafloor around Palmer Station shows deep troughs scoured by receding glaciers. The map is based on more than 180,000 soundings taken from the inflatables. (Map generated by Scott Gallager, WHOI)
