The University of Maine Ocean Observing System (UMOOS), a member of the Northeastern Regional Association of Coastal and Ocean Observing Systems (NERACOOS), has been operated by the University of Maine's Physical Oceanography Group (PhOG) since 2001. UMOOS currently maintains five real-time data buoys in the coastal Gulf of Maine (GoM) and two in the offshore GoM. Since September 2013, PhOG has been intermittently deploying Teledyne Webb Slocum G2 gliders to study spatial variability near, and between, several UMOOS data buoys in two principal branches of the Gulf of Maine Coastal Current, the Eastern Maine Coastal Current (EMCC) that extends along the eastern coast of Maine to Penobscot Bay, and the Western Maine Coastal Current (WMCC) that extends westward from Penobscot Bay toward outer Cape Cod. The gliders are equipped with a standard sensor suite that measures salinity, temperature, pressure, chlorophyll 470/695 nm), turbidity, and a dissolved oxygen optode. This manuscript evaluates two of the most recent sensor packages added to the potential payload of gliders: a Teledyne RDI 600 kHz phased-array ADCP and a wave module developed by PhOG in collaboration with Ocean Science and Technology (OST). |
