The SeaFET sensor is a deployable pH sensor developed by Prof. Todd Martz at UCSD-Scripps. We are excited to be deploying the first one (of hopefully several?) in McMurdo Sound under the sea ice this season. We will be measuring environmental pH with the logger, and sampling water with a Niskin bottle throughout the season to assess the carbonate chemistry at our fish hut field site.
With our very own hole in the ice we had the McMurdo divers Rob Robbins (right) and Steve Rupp (left) deploy our custom SeaFET sensor at a location near Cinder Cones. This site will hopefully be exposed to some Ross Sea current activity, and is also in the vicinity of one of the long term field sites originally used by Prof. Paul Dayton and now being surveyed by Prof. John Oliver and his dive + ROV team.
