What a great start! Last weekend we embarked thirty-one scientists and technicians representing ten education and research institutions in preparation for our third of four science missions. The focus of this mission is to service moorings and carry out hydrographic measurements for the yearly assessment of the western Arctic Boundary Current which flows from the Barrow Canyon to the continental slope of the Beaufort Sea.

The three types of moorings that we will be servicing are: passive acoustic, chemical, and physical moorings. Passive acoustic moorings measure marine mammal calls. Chemical moorings quantify air to sea gas exchange, and physical moorings measure water properties and circulation in the Barrow Canyon. Thus far we have successfully recovered three, and deployed two hydrographic moorings. Bravo Zulu to the watch standers, scientists, crewmembers in the small boat and out on deck for demonstrating exceptional teamwork, and for the successful mooring evolutions that we completed thus far.

Until Next Time,
