Greetings from the R/V Atlantis! NOPP-GIW is heading for the north Pacific!
The SIO/WHOI IWR array and the WHOI/UDel long line array will both be deployed off the continental shelf and slope in a massive internal tide beam emanating of the Aleutian Island chain. While this is happening, SQUID floats will be launched in coordination with the UW-APL team for a large coordinated NOPP-GIW effort to map these internal waves. In addition to the NOPP-GIW field ops, a crew of scientists and engineers from WHOI have joined the NOPP-GIW cruise in a coordinated science mission to launch an autonomous underwater vehicle (AUV).

We’ll start deploying CPIESs tomorrow morning as we await the perfect weather for the mooring deployment (likely Thursday) and while Masako, Maurice and Sean pour through the survey data for the targeted seamount dive later during the cruise.

Weather has been great. The Atlantis crew is remarkable and our science party is a fun (and competent) bunch. Good cohesion all around.
Your Atlantis AT50-39 Chief Scientist,
