In a mooring deployment, the 3800 lb anchor goes down first; the acoustic releases are located above the anchor.  And the canister to the left contains a bottom pressure recorder. (Peter Lourie)
Fifty yellow flotation glass balls in 4 m segments are attached near the anchor as a back-up recovery system in case the large yellow float at the top end does not appear, or perhaps gets stuck under the ice when it is released from the anchor. (Peter Lourie)

The MMP profiler is kept warm in a small shack until it is time to attach it to the line.  (Peter Lourie)
Jeff O’Brien programs it and is helped by Cory Beatty and Rick Krishfield in attaching it to the line before it is lowered into the sea. (Peter Lourie)
Will Ostrom and Bill Galliot make sure the delicate profiler is lowered carefully over the side while Kirby Vatcher in the crane moves everything very slowly.  If an instrument sticking out of the profiler is nicked, there’s a chance the device won’t record the valuable data. (Peter Lourie)
The profiler hits the water. (Peter Lourie)
The syntactic floatation sphere at the top of the mooring is positioned into place and lowered into the water as the final stage of the mooring deployment. (Peter Lourie)
The instruments hanging from the float are an acoustic transponder, Microcat CTD recorder, and SAMI CO2 and pH samplers. (Peter Lourie)
