Overview map of the ODP 889 node and instrument locations. (Device IDs in parentheses. Click to enlarge. See the map archive for previous deployments.)
This site on the mid-continental slope (1260m deep) off south-central Vancouver Island is rich in shallowly buried gas hydrates. (Click the maps to see enlargements.)
Research objectives
NEPTUNE Canada will help scientists monitor changes in hydrate distribution, depth, structure, properties and venting, particularly related to earthquakes, slope failures and regional plate motions. To learn more, visit the Bullseye Vent Gas Hydrates experiment.

Borehole at ODP 889
Crabs patrol the margins of a borehole drilled at site 889 (1315 m) in October 1992. This is one of 1797 boreholes drilled by the Ocean Drilling Program (ODP), a Joint Oceanographic Institutions for Deep Earth Sampling (JOIDES) project that gathered seafloor core samples around the world between 1985 and 2003. The ODP furthered basic research into the history of the ocean basins and the overall nature of the crust beneath the ocean floor.
NEPTUNE Canada's ODP 889 node and instruments are located adjacent to this borehole site.
