The start of the Cape Cod Bay 2019 Survey. Eric, Wayne, and Dave are made sure the streamer was ready for when they reach the study area.

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.
 

 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.

USGS scientists installed a thermal imaging camera on a current USGS streamgage on the Neversink River near Claryville, New York. This equipment will help monitor surface water temperatures and can help understand the amount of groundwater contributing to surface runoff.
