Nancy Steinberg writes about a high-tech advance in commercial crabbing for Oregon Stater, the Oregon State University alumni magazine. The crab pots that local fishing crews crank into the sea have a small oxygen sensor attached to the side, to locate areas of hypoxia. Nancy (@NDSteinberg) explains how the real-time, hyperlocalized, wirelessly transmitted data about areas of low oxygen benefits both scientists and crabbers. image: Pat Kemmish
