ODP 1027
Plan map for the Ocean Drilling Program (ODP) 1027 location. (Device IDs in parentheses. Click to enlarge. See the map archive for previous deployments.)
This mid-plate site is on the abyssal plain at a depth of 2,660m. (Click the map to see an enlargement.) Here, NEPTUNE Canada connects to existing Ocean Drilling Program borehole monitoring systems. CORK systems monitor changes in crustal temperature and pressure, particularly as they relate to earthquakes, hydrothermal convection or regional plate strain.
This site also forms part of a plate-wide tsunami detection system that uses highly sensitive bottom pressure recorders to measure tsunami amplitude, propagation direction and speed. Data from this system complements information gathered by other tsunami sensors around the North Pacific.

Putting a CORK in it
NEPTUNE Canada will connect to two Circulation Obviation Retrofit Kits, or 'CORKs' at the ODP 1027 site. These kits, which were installed in Ocean Drilling Program boreholes in 1996 and 2002, allow geoscientists to monitor changes in sub-surface temperatures and pressures caused by earthquakes, hydrothermal convection and regional plate strain. CORK data logging units will be upgraded to enable continuous real-time sampling via NEPTUNE Canada's high-speed network.
