Legend Dartmouth to Resolute July 2 – July 10 Resolute to Kugluktuk July 10 – July 17

LSSL July 2 – Embark Dartmouth, NS July 2-10 – Science Leg From Dartmouth to Resolute Bay to Kugluktuk –Labrador Sea, Davis Strait, Baffin Bay, Lancaster Sound, Bellot Strait and Arctic Archipelego Box coring operations. Vertical net tows. CTD/rosette casts and concurrent deployment of ADCP during casts. Plan for rosette casts is for twice daily stations along track and additional sections, one as the ship enters the Labrador Sea and the second across northern Davis Strait. The eastern part of this latter section is in Greenland waters. Deployment of 3 moorings at the eastern end of Bellot Strait. Deployment of drift bottles at intervals along the track. A 6- hour stop at Resolute to exchange science personnel and hold meeting/tour aboard for invited guests from the community

LSSL Opportunities: –Dartmouth to Resolute: 17 people –Plus media

LSSL Kugluktuk to Canada Basin program and return to Kugluktuk –July 17 to August 21 Recover 4 moorings and deploy 4 moorings Recover 1 ITP (Ice Tethered Profiler) buoy if easily accessible Deploy 4 ITP drifting buoys and several arrays of 6 ice-tracking buoys Deploy XCTDs (approx 140) Conduct CTD/rosette profiling and sampling program at science stations. Conduct net casts at approx science stations Deployment of drift bottles at intervals along the track. Collection of near-ship CTD profiles, water and ice samples Underway measurements, including: –Underway CTD or XCTDs deployed from stern –Seawater loop Possibility of sediment box cores – hour casts with sediment pumping equipment to 3000+m.
