Science Objectives | |
To carry out geophysical surveying (seismic and tow-camera imagery) across the shelf-break southeast of Martha's Vineyard over areas of potential fluid seepage and seafloor failure. recovery of 5 seafloor instruments. Deploy a wave-glider and collect a profile of towed magnetics data. deployment and recovery of a shielded ocean bottom seismometer | |
Science Activities | |
-deploy LDEO seismometer -collect an across-shelf magnetics profile -recover 5 WHOI seafloor MT instruments -deploy waveglider while MT instruments are being recovered -tow a series of seismic lines with sparker source and streamer -carry out a series of deep-tow camera profiles | |
