Benthic Pod

A unique combination of technologies that enable investigators to more effectively collect, manage and analyze very large data sets from deployed moorings.

Satlantic manufactures a range of mooring management and controller solutions designed to overcome the traditional challenges associated with mooring management systems, such as power constraints, communications bandwidth, and complex data formats. Our systems employ a unique combination of technologies that enable investigators to more effectively collect, manage and analyze very large data sets from deployed moorings. As a result, information will be more readily available for multidisciplinary scientific models and for commercial and recreational users of aquatic environments.

Satlantic has worked closely with Dalhousie University to design and manufacturer the Benthic Pod, a sophisticated system to monitor and report key oceanographic parameters as part of the Ocean Tracking Network (OTN). The OTN program, headquartered at Dalhousie University in Halifax, Nova Scotia, is conducting the world's most comprehensive and revolutionary examination of marine life and ocean conditions and how they are changing as the earth warms.

The Benthic Pod consists of an array of sensors controlled by the Satlantic STOR-X data logging, power and control system that will measure depth, salinity, density, water temperature and dissolved oxygen at regular intervals near the sea bottom. These important parameters, collected in biologically sensitive areas, provide long term, high-resolution data required to develop and enhance physical and chemical ocean models. Data is archived on board the STOR-X system with sub samples delivered via acoustic modem through a fish-tracking receiver to passing ships at the surface.
