Summary of Activity and Data Gathered: SEABOSS operations were conducted in Long Island Sound aboard the R/V Connecticut from May 8-15, 2018 as part of an agreement with LISMaRC project, partnered with scientists at UConn and Univ of New Haven. A total of 117 sampling sites were occupied during the survey where videos, still photographs and sediment samples were collected using the Interocean version of the SEABOSS. Navigation was determined using a WAAS-enabled Garmin GPSMAP 76C GPS receiver that was located approximately 3 meters away from the SEABOSS deployment point.

Notes: SEABOSS operations will be conducted in Long Island Sound aboard the R/V Connecticut as part of an agreement with Univ of Connecticut (LISMaRC project) to map the geology and biota of Long Island Sound. This work is in conjunction with additional collaborators from University of New Haven and Lamont Doherty Earth Observatory (Columbia University).
