Acoustic backscatter from sites in McMurdo Sound from 2014-2015 (McMurdo Predator Prey project)
<p>Krill and fish were sampled acoustically and visually beneath the fast ice using the tethered SCINI ROV, which was deployed and operated through a 25 cm diameter hole drilled through the sea ice. SCINI contained cameras and thrusters, and towed a sensor package consisting of a WET Labs fluo...
