Summary of Activity and Data Gathered: Fifteen lines of data were collected, with approximately 7 in Salt Pond and 8 in the northern half of Nauset Marsh. The cruise was scheduled to take advantage of the unusually high proxigean tide at about 11:30 AM which permitted access to parts of the marsh that would have otherwise not been navigable. Part of the planned survey area (esp. the eastern half of Salt Pond) could not be navigated due to moderately thick ice. The rest of the area was either open water, or was covered by only a thin layer of ice that could be penetrated by the boat. Data were collected with the 50-m streamer by a team on land holding the end of the streamer and stretching the streamer out until the boat could pull it tight and start collecting data. Data processing began on March 1 and incorporated water conductivity measurements and fathometer data into the processing of resistivity lines. Results will be communicated to WRD collaborators to guide modeling efforts. Additional vibracoring and porewater squeezing is also planned for spring/summer 2006 based on results of this survey.
