Two of the USVs were equipped with Gen1 ASVCO2 sensors and two were equipped with Gen2 ASVCO2 sensors. The objectives of this mission include mapping contours within the Arctic for uncharted or minimally charted parts of the sea, and performing intercomparisons between the Gen1 and Gen2 ASVCO2 systems in the Arctic environment. If pCO2 is calculated, the TEMP_DEPTH_HALFMETER sensor should be used as the primary sea surface temperature when calculating pCO2.";
