Animated Data!

Our presentation at the 2016 Alaska Marine Science Symposium included ananimated stripchart recorder visualization of a number of the mooring fields. The data are intriguing, with plenty of features that require some investigation.

Real-time Data Float Release

On November 8th, Peter Winsor issued the "Release Float" command and sent the freeze-up surface buoy floating away from the advancing ice edge. SAR satellite imagry indicated that the main ice pack was less than a day from over-riding the mooring and that a few individual ice floes may have already been in the vicinity. At the time the release was triggered, the water column was isohaline and isothermal, with the temperature about 0.3 degrees C above the freezing point. We were thrilled to see the mooring work as designed: real-time data right from the surface to the seafloor right to the moment of release.

2015 Mooring Turn-around

Our August and September 2015 recovery and deployment operations were successful; the deployment was accomplished by partnering with the Arctic Marine Biodiversity Observation Network (AMBON) program's summer 2015 survey cruise. The observatory re-deployment consisted of three moorings: (A) currents, waves, temperature, salinity, pressure and marine mammal recordings; (B) Active acoustics, temperature, salinity, pressure, fluorescence, colored dissolved organic matter, optical backscatter, dissolved oxygen, nitrate, PAR, and sediment trap; (C) real-time water column stratification (temperature and salinity) from the surface to the bottom and water column photography. We documented our activities and the AMBON trawls collected near the mooring site with lots of photographs.
