Catching Crabs in a Suffocating Sea


Frances Chan, a researcher at Oregon State University first came across hypoxia or dangerously low-levels of oxygen in the ocean in Oregon back in 2002. To better understand the issue and empower crab fishers whose livelihoods suffered as a result, he helped develop "small, low-cost oxygen sensors" that fit into their crab pots and read the levels of oxygen in water in real time as they fish. This year, 38 instruments were sent out on eight boats, and with time, the information could help fishers adapt.
