Peggy's Cove Lighthouse south of Halifax
Friday 11 to 16 May
David Hydes travelled out to Halifax in Canada to work with Doug Wallace’s group in the Oceanography Department at Dalhousie University. The task is to assess the performance of the SNOMS tank under-laboratory conditions, and the performance of old and new designs of sensors. The Wallace group are keen to develop the SNOMS flow through tank concept for use on three new routes working with merchant ships in the North Atlantic, starting later this year. Daniela Turk is leading the work in Doug's Halifax group.
The tests
are being carried out in the University’s Aquatron facility (http://aquatron.dal.ca/)
a world leading laboratory space with extensive wet laboratories for carrying
out testing and experiments with large volumes of seawater pumped directly from
the sea.
Working
with the Aquatron engineering team a laboratory space was converted for the
experiments which will run for the next few months. This will enable the
relative accuracy and precision of the instruments to be assessed over the kind
of time scales they will deployed on ships or data buoys.
New
instruments will be tested from ProOceanus (http://www.pro-oceanus.com/),
Satalantic (http://www.satlantic.com/ph-sensors) and
RBR (http://www.rbr-global.com/products)
along with the ProOceanus and Aanderaa units (www.aadi.no/)
already used in the SNOMS system.

Many thanks are due to Jim and his team Steve, Lee and Craig for getting everything set up so quickly and efficiently in the lab.
Some thing extra.
The ACL ship the Atlantic Companion docked in Halifax on Tuesday.
She carries the Kiel CO2 system which now includes a cavity ring down detector
