Data Processing

Survey campaigns

We attend and/or organize survey campaigns to

  • acquire and post-process multibeam echosounding data (bathymetry)
  • operate oceanographic and hydroacoustic instruments like CTDs or echosounders,
  • process, manage and visualize scientific datasets.

Polarstern’s PS101: Seamounts and their data

Three colleagues of ours supported a science team around Prof. Dr. Antje Boetius on Polarstern's campaign PS101 to Karasik Seamount in the Arctic. They were responsible for the ship's IT infrastructure, the operation of the echosounders ATLAS Hydrosweep and Parasound as well as analysis, processing and documentation of acquired datasets e. g. from underwater navigation systems. Additionally to all that they found a new sea mount close to the Gakkel Ridge. Read more

Data and charting service on Meteor’s M126 BIGMAR cruise

Finding and exploring hydrothermal vents at the Mid-Atlantic Ridge was the objective of a scientific crew sailing on RV "Meteor" in April 2016 which had kindly asked FIELAX to support. A colleague of us attend the cruise, mapped wide areas of the deep sea ridge structures with the ship's multibeam echosounder and processed the data to maps. He also processed and managed acquired photography and navigation data from the MARUM's ROV "Quest" in order to quickly get overview maps and results to support cruise planning and documentation. The contractor was Prof. Dr. Nicole Dubilier from Max Planck Institute for Marine Microbiology in Bremen. Read more

Navigation data processing “Master Track”

On behalf of Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung we post-processed navigation data from former campaigns of the research vessels Polarstern and Heincke. The job was about data validation, filtering, interpolation, generalization and documentation of all applied processes. The objective was to achieve a valid "master track" for each campaign which will be used for georeferencing scientific data and for visualization in data portals. Read more
