Event description

Description

The back side of the Moon has been mapped in much greater detail than the bottom of Earth’s oceans. Although 71% of the Earth’s surface is covered by oceans, only about 13% of the oceans has been mapped, and less than that in any significant detail.

Norm will present a general and personal history of seafloor mapping, the reasons that the need is important, and the future of creating accurate maps of the seafloor for future generations. In addition to purely scientific or exploration aspects of understanding how oceanic crust forms there is a practical side to seafloor mapping as well.

The lead picture above shows an example what happens when there isn’t a good map of potential collision hazards. The nuclear submarine USS San Francisco struck an unmapped volcanic pinnacle about 350 miles southeast of Guam on 8 January 2005 as it headed to Australia from Guam at a speed in excess of 30 knots at a depth of about 160 m. Fortunately the pressure hull was not breeched. There was, however, loss of one life and several injures.
