A sub-bottom profile of CHIRP seismic data is draped over swath bathymetry showing the Gulf of Maine pockmark field stratigraphy common to the area. Seafloor mapping combined with sub-bottom geologic profiles shows that Holocene mud ranges in thickness between 5 and 10 meters but pockmarks in Belfast Bay do not penetrate below the geologic unconformity. Th

The Native communities’ in-ground food storage facilities are being lost as a result of eroding bluffs and thawing permafrost.

Looking astern, the airgun sled is in its cradle in the center of the photo.  The crew are manually recovering the multichannel streamer and beginning the large figure-8 shape of coiling it on deck. Work at sea occurs 24 hours a day.  In late September, there is ~12 hours of night, resulting in gear recovery at night.

Science crew ran the multichannel seismic equipment, sonobuoy refraction equipment, navigation, marine mammal observations program, and incidental science studies.  Dr. Deborah Hutchinson (USGS liaison aboard the Canadian icebreaker) is 7^th from the right.  Dr. David Mosher, Chief Scientist aboard Louis is 10^th from the right.
