Dispatches from the Arctic

Engineering Assistants Jim Ryder and Jeff Pietro assemble the tether of an Ice-Tethered Profiler (ITP). ITPs operate autonomously to acquire temperature and salinity measurements from the upper ocean under sea ice while drifting with the ice floes, and transmit information back in near-real time. Eight ITPs will be deployed throughout the Arctic this summer to augment those already in the field. Four will be deployed on a Beaufort Gyre Observing System cruise on the Canadian Coast Guard icebreaker Louis S. St. Laurent. Follow live daily dispatches throughout the duration of the cruise.
