TRT measurements Off-/Near-/Inshore Holland – cooperation with MSH

This autumn, FIELAX has gathered data for two cable route projects with Marine Sampling Holland ( We have measured a total of more than 100 profiles of temperature and TRT (thermal resistivity) data offshore Holland as well as in the Ijsselmeer. As the requirement was high resulotion profiling to a sub-bottom-depth of >6m, special coiled sensor tubes with a total length of 8m were manufactured. Read more

TRT measurements in tidal seas

Since spring this year, FIELAX performs TRT measurements in tidal seas down to 6m below sea floor. The picture shows the installation of a 3,5m sensor string. The whole equipment can be transported 'per pedes' through the Wadden Sea.
