The research vessel HEINCKE of the Alfred Wegener Institute is regularly sailing the North Sea and the North Atlantic. Temperature and salinity of the surface seawater is measured continuously during these voyages. FIELAX has been processing these data since 2015. So far, more than 220 voyages (incl. reprocessing of voyages since 2009) could be made available via the data repository Pangaea (https://www.pangaea.de/?q=heincke+tsg+). During Read more
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.
Where have you been, Polarstern?
FIELAX/AWI give an answer in a recently published article in Hydrographische Nachrichten (Hydrographic News). It is about 35 years of navigation data history of the German research ice breaker RV "Polarstern". Read more
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
