Merry Christmas and a Happy New Year!

We wish a Merry Christmas and a Happy New Year to all our clients, partners and friends!

We are glad we could support the following projects in 2016:

Programmable converter box for serial data (RS232/RS422)

The German research icebreaker RV “Polarstern” now operates with programmable converter boxes by FIELAX. This box can read incoming serial data (interfaces RS232/RS422), convert/transform it by a programmable micro controller and output it serially. Multiple boxes have been installed on “Polarstern” to convert NMEA and binary data from a motion sensor to feed devices requiring specialised input telegram formats. Contractor was Reederei F. Laeisz GmbH.

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.

Review article about sediment temperatures and 2K-criterion available online

A team of scientists from FIELAX has submitted a manuscript about the variability of sediment temperatures and the so-called 2K-criterion to the Elsevier journal ‘Applied Thermal Engineering’. The manuscript: /Temperatures in shallow marine sediments: Influence of thermal properties, seasonal forcing, and man-made heat sources/ was accepted today and is available under the following link:

Highlights of this article are:

  • Sediment thermal properties are highly variable.
  • Seasonal forcing causes large spatial and temporal sediment temperature variations.
  • Power cable temperatures strongly depend on thermal properties of a given site.
  • The 2K-criterion is not suitable to detect man-made heat injection.

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.
