An abstract of a poster presented in the 2006,
American Geophysical Union Fall Meeting in San
Francisco presented evidence of a possible asteroid
impact in the central Arctic Ocean on Alpha Ridge.

This abstract is;

Hall, J.K., a, Y., Hunkins, K., Ardai, J., Coakley, B.,
Hopper, J., the Healy 2005 seismic team, 2006. Evidence
for an asteroid impact in the central Arctic Ocean.
Poster OS53B-1114, American Geophysical Union Fall
Meeting, San Francisco, Dec. 11–15.

It can be found at:

This possible impact is mentioned in:

Kristoffersen, Y., B. J. Coakley, J. K. Hall and M.
Edwards, 2006, Mass wasting on the submarine Lomonosov
Ridge, central Arctic Ocean. Marine Geology. vol. 243,
no. 1-4, pp. 1-246. (September 2007)

If the proposed impact is related to the mass-wasting
on the submarine Lomonosov Ridge, then it would be
over 600,000 years old and pre-late Pleistocene in age.

Yours,

Paul H.
