OBS-Thermo

Projektleitung:Dr. rer. nat. Jörg Bialas
Beteiligte:Dr. rer. nat. Sven Petersen, Dr. Thomas Feseker
Förderer:Cluster of Excellence "Future Ocean"
Stichwörter:hydrothermal fields;OBS;temperature sensor;ROV;micro-seismicity;vent fluid
Laufzeit:1.11.2008 - 31.12.2009
Inhalt und Ziele:OBS-Thermo sets out to overcome the mismatch in observation times of different sensors and to build a first base of combined and co-registered measurements at hydrothermal fields. For this purpose an OBS shall be extended with a temperature sensor and be deployed at 5°S on the southern Mid-Atlantic Ridge in 2009. With the ROV controlled deployment of the thermal sensor in the chimney of a black smoker the OBS-Thermo will co-record local seismicity and vent fluid exit temperature and hence correlate thermal events with increased fluid flow, which should be recorded as increased micro-seismicity. This system will be the base of a new local network of sensors independent from external power supply to be used in future seafloor hydrothermal research.
