Spaceborne Ocean Intelligence Network (SOIN)
SOIN Project Goals
a) To advance Canada's ability to produce meteorology and oceanography products in support of maritime defence and civilian-security operations;
b) to monitor mesoscale oceanographic fronts and eddies with spaceborne synthetic aperture radar sensors;
c) To provide Canadian Forces MetOc Halifax with the operational tools to distribute resulting METOC products to civilian security-related operations.
