Arctic Heat Open Science Experiment

Summary:
This project aims to bridge the upper ocean observation gap in the Arctic marginal seas through the deployment of innovative new autonomous platforms like Marine Robotic Vehicles (MRV) Air-Launched Autonomous Micro-Observer (ALAMO) float, in combination with a more traditional suite of weather and ocean-sensing instrumentation carried aboard a specially-modified NOAA Twin Otter aircraft.

An ALAMO float begins an observation cycle at the surface, descends to a parking depth, remains there for a designated period of time, optionally descends deeper, ascends to the shallowest depth it can reach, remains there to transmit data and get a position fix if at the surface, and then begins the next cycle.  Only ascent data are presented here.
