Project LOLEM:
LOLEM is an acronym for "Logatchev Longterm Environmental
Monitoring".
The overall goal of the project is to monitor environmental parameters (temperature, pressure,
seismicity) at the Logatchev Hydrothermal Field over a longer period of time (1 year or longer) to
provide a basic data set for all long-term investigations of biological communities and for all studies
of the hydrothermal plume, its sources and its development over time. One focus of temperature
monitoring effort will be to assess the low temperature diffuse outflow from fissures and fractures.
In addition a probe will be developed to measure temperatures at selected locations and transmit
them in real-time to guide ROV operational decisions. The deployment and recovery of all
instruments (with exception of the water column profiling loggers) depends entirely on the
availability of a deep sea ROV or submersible, which avoids the need for expensive release
systems. The proposed technical development will provide the basic instrumentation for
monitoring other submarine hydrothermal fields for all members of the research focus Schwerpunkprogramm 1144.
Several research cruises on FS Meteor and the ROV Quest
of MARUM are plane in the central
Atlantic, i.e. M 62/2 scheduled
8-August-2004 - 31-August-2004 and M 63/X 6-May-2005 - 7-June-2005.
