Objectives	This science program onboard the CCGS Louis S St-Laurent took place between July 17 and August 21 in the Canada Basin from the Beaufort Shelf north to 83°N. Full depth CTD casts with water samples were conducted, measuring biological, geochemical and physical properties of the seawater. The deployment of expendable temperature, salinity and current meter probes increased the spatial resolution of measurements. Moorings and ice-buoys were both serviced and deployed in the deep basin for daily time-series. Hourly ice observations were taken and on-ice surveys conducted. Zooplankton net tows, phytoplankton and bacteria measurements were collected to examine lower trophic level distributions. Underway measurements were made of the surface water. For outreach, a middle school teacher from Durham Academy, NC brought in by WHOI from an organization called PolarTREC, sent out daily dispatches for the WHOI and PolarTREC's websites, as well as responding to students' questions regarding the program.
