Dr. Christopher Sabine (Professor, University of Hawaii) provides step-wise training and helpful hints for setting up, deploying, and retrieving data from the iSami-pH ocean sensor. The iSami-pH -Submersible Autonomous Moored Instrument – measures and logs pH or pCO2 in marine and freshwater environments over long periods with ultra-low power and reagent consumption, providing valuable time-series data. The sensor was winner of the Wendy Schmidt Ocean Health X-prize in 2016. For details regarding purchasing the sensor, contact Sunburst: sunburstsensors.com
