Designing exploratory robots that collect data for marine scientists


Massachusetts Institute of Technology
As the Chemistry-Kayak (affectionately known as the ChemYak) swept over the Arctic estuary waters, Victoria Preston was glued to a monitor in a boat nearby, watching as the robot’s sensors captured new data. She and her team had spent weeks preparing for this deployment. With only a week to work on-site, they were making use of the long summer days to collect thousands of observations of a hypothesized chemical anomaly associated with the annual ice-cover retreat.
The robot moved up and down the stream, using its chemical sensors to detect the composition of the flowing water. Its many measurements revealed a short-lived but massive influx of greenhouse gases in the water during the annual “flushing” of the estuary as ice thawed and receded. For Preston, the experiment’s success was a heartening affirmation of how robotic platforms can be leveraged to help scientists understand the environment in fundamentally new ways. ....

Silent sea: UC Santa Barbara scientist locates thousands of DDT-filled barrels in Catalina Channel


Dr. David Valentine poses with the Sally Ride research vessel during a trip in 2017 helping responders respond to the Thomas Fire, which impacted Ventura and Santa Barbara counties.
Reports in old ship logs of thousands of barrels of DDT being dumped into the Catalina Channel during the 1950s were confirmed in 2011 by photographs taken by UC Santa Barbara marine scientist Dr. David Valentine

Peninsula residents have grown up seeing “Do Not Eat Contaminated Fish” signs at local piers and beaches. The signs warn against catching and eating White Croaker, Black Croaker, Barred Sand Bass, Topsmelt and Barracuda.  ....
