The Air Sea Interaction Lab will keep this space updated with the latest information from the EquatorMix South Pacific research cruise taking place October 4th - October 22nd, 2012 aboard the R/V Revelle. The EquatorMix Data Products Summary Page provides informational links and plots of the latest publically available data (also permanently linked at the top of this page).
October 6th, 2012
Currently we are in route aboard the R/V Revelle at 9° 36.0′ S by 145° 24.0′ W heading toward our final destination of 0° N by 140° W. You can continue to track our real time location through Droopy. All shipboard equipment is installed and operational. Airborne equipment is installed and static engine tests and an EMI check were performed today while under way. First flight is tentatively scheduled for Monday, October 8th. Click the thumbnails below to see full size images.
October 7th, 2012
Transit continued again today aboard the R/V Revelle. Test deployments of the Skyhook ScanEagle recovery system was completed as shown in the pictures below. We are on schedule for turret video payload test flights tomorrow while still underway to the final posit.
October 8th, 2012
Today we had a successful first flight with the turret video payload. Environmental conditions: 16 knot winds, scattered clouds. Scientific payload flights are anticipated to start tomorrow after we reach our station (0° N, 140° W).

A longer followup flight took place today with the flux measuring payload. Below is a look at the supporting shipboard instrumentation which includes a laser doppler wind profiler with 20m-binned readings up to 400m located just above the flight deck (left) and a MET system with 20 hz eddy flux measurements, a 30khz scanning LIDAR, and a single point laser distance meter all packaged on the foremast of the R/V Revelle located approximately 17m above the surface of the water (right). Today's launch video is linked below as well.

Today is a layday for our team in preparation for the forthcoming flux measuring flight which will begin at midnight tonight. We have uploaded a related poster below that we presented in February 2012 at the AGU Ocean Sciences Meeting in Salt Lake City for background reading: "Development of instrumentation for direct observations of air-sea interaction from land- and ship-based UASs".
October 17th, 2012
This afternoon we had another successful flight of the flux measuring payload. Below are pictures from the launch, a low level turn, and a composite image of a recovery sequence (credit San Nguyen).
October 19th, 2012
Today we completed our ScanEagle flight operations with two 11-hour back-to-back flights of the flux measuring payload.
For a few hours during the first flight, the imaging payload was also in the air for vertically-stacked formation flying.
Below are pictures of the final "flux" recovery and a still from the nadir-looking visible camera in the imaging payload during stacked flight.
In total, we logged about 71 hours in the air, with 11 flights in 12 days.
