Sound velocity casts on Cape Cod Bay

Sometimes the fog can be as thick as pea soup! The captains use radar and keen eyesight to navigate in such conditions. Woods Hole Coastal and Marine Science Center staff,  Alex Nichols and Wayne Baldwin,  take a sound velocity cast off the back of the boat.

Subbottom profiler deployment on Cape Cod Bay, 2019

 Before deploying the subbottom profiler for leg 2 of the seafloor mapping cruise, Wayne Baldwin, Alex Nichols, and Chuck Worley made sure the floats were sufficiently inflated. In the relatively shallow waters of Cape Cod Bay, they want the instrument towed at water's surface for the resolution of the sub seafloor geology.

Wayne Baldwin, Alex Nichols, and Brian Andrews get the 512i chirp subbottom profiler back on deck! The instrument weights ~500lbs. and requires the ships A-frame to lift it! We only take the chirp out of the water when we need to perform maintenance, transit rapidly, or for weather. We always try to get the chirp back in the water ASAP so we can get back to data collection
