John Hall received his PhD from Lamont in 1970. His thesis involved geophysical mapping of the Arctic Ocean from Ice Island T-3 (Fletcher's Ice Island). Upon graduation he moved to Israel, and spent 35 years with the Geological Survey of Israel. In 2003-2004 he was a Visiting Scholar at CCOM. During this time he became reacquainted with the Arctic, participating in CCOM's UNCLOS cruises in 2003, 2004, 2008, and 2009. While at CCOM in 2004 he partnered with Prof. Yngve Kristoffersen of the University of Bergen and CCOM in the building and equipping of a research hovercraft to carry out oceanographic, geological, and geophysical investigations. This platform offers a relatively inexpensive way to carry out research in the most inaccessible parts of the Arctic Ocean. The particular target is the study of a possible asteroid impact zone on the Alpha Ridge north of Ellesmere Island, site of the oldest cores thus far raised in the Arctic.
