Data management at the South West Indian Ridge
In heavy seastate we attended Polarstern cruise ANT-29/8 to the southwest-indian ridge for acquiring sub-bottom sonar data as well as creation of data and maps.

Within a project about heating of marine sediments (MoniTherm, co-financed by the 'Europäischer Fonds für regionale Entwicklung'), FIELAX has developed a full model for the temperature field in and around submarine power cables. Read more
Research vessel RV Polarstern
The German research vessel "Polarstern" is an important instrument of the German polar and marine research. The ship has an own data centre, a complex IT infrastructure and hundreds of scientific sensors which were maintained and supervised by seagoing FIELAX personnel throughout the years 2002 to 2013.

In 2012, FIELAX adapted its well-established Heat Flow measuring system to a VKG6 type Vibrocorer in order to measure thermal gradient and conductivity measurements in shear resistant marine sediments. The combined system has been successfully operated on many cable route surveys for the connection of Offshore Windparks to the main land.In cooperation with Marine Sampling Holland, FIELAX has further developed the system to work with a CPT unit used for in-situ geotechnical measurements, in order to overcome possible liquefaction, which may occur in very sandy sediments due to the vibrocoring. Therefore the sensorstring was adapted to fit into a standard coiled CPT-tube of 6 m length i.e. the number of temperature sensors was reduced to 13 temperature sensors at a spacing of 42 cm.A first successful test of this new system was carried out together with Marine Sampling Holland (see also http://www.marinesamplingholland.nl) this September in a geotechnical survey in the North Sea.
