SeaHorse™ Data #1

- Data Collected by SeaHorse

The Canadian Department of Fisheries and Oceans are collecting bi-weekly measurements 30 kilometers offshore from Halifax (Station 2, Halifax Line) as part of their "Atlantic Zonal Monitoring Program". SeaHorse is being integrated into this program as a means of reducing the ship time requirement for this periodic monitoring, and also to acquire, over extended periods, the high profiling frequency and vertical resolution needed to resolve sporadic or high-frequency events. This particular deployment captures an upwelling event that peaks around Oct 15. Evidence of vertical mixing can be seen in both the temperature and salinity records. There is also a coinciding increase in chlorophyll concentration in the surface layer indicating a phytoplankton bloom that has likely been triggered by a supply of nutrients mixed up from deeper waters.

Jim Hamilton is a physical oceanographer whose interests include the development of new oceanographic instrumentation and measurement techniques. He has worked extensively in the development of instrumented moorings. Current projects include an Arctic Ocean climate study and coastal monitoring work.
