History/Background:

The observatory, in its current instrumentation, is designed to measure and monitor the effect of earthquakes on subsurface fluid migration. In its first attempt we measure fluid/water escape within an active pockmark directly, then use the local seismicity to calibrate changes in fluid migration to earthquake activity. In its current figuration, the seabed structure has sufficient battery power for almost 8 months.

Parameters measured:
Seismicity and fluid flow (vertical or horizontal)

Method of transmission:
Autonomous (not near real-time)

Instrumentation: 3-component seismometer K/MT210 4.5Hz, OceanLine water current/flow meter (HS-2x series)

Deployment(s): 2 test deployments took place in 2009 on an active, fluid emitting pockmark outside Patras Harbour, Eastern Ionian Sea, Greece

Latitude and Longitude: 38°12.403'N, 19°39.022'E

Depth: 35m (operating depth for trial)

Oceanographic region: E Ionian Sea, Mediterranean
