Mapping benthic habitats in Greenland (MapHab) (39574)

Project Details

Description

In the DANCEA funded MapHab project, a research consortium consisting of four scientific institutions was established: Greenland Institute of Natural Resources (GINR, Greenland), Geological Survey of Denmark and Greenland (GEUS, Denmark), National Institute of Aquatic Resources (DTU Aqua, Denmark) and Institute of Zoology (IoZ, United Kingdom) in order to take the very necessary step towards developing a best practice protocol for detailed seabed habitat mapping in Greenland.

The GINR’s survey ship R/V Sanna has recently been equipped with multi-beam echo sounder (Reson SeaBat T50-ER) and ground-truth gear (video sled, drop camera and grab). This framework allows an effective sampling program combining both acoustic survey with on-board processing and ground-truth sampling. The post-cruise mapping analysis forms then the basis for identifying locations for in situ sampling, which again is used to verify the mapping analysis.

The projected ‘best practice’ protocol was designed as a cost-effective and time-efficient mapping program of the strategically important areas of the Greenland shelf. The priority of this protocol is ‘mapping for discovery’, i.e. a single survey usually carried out for the first time in order to explore the seafloor and collect data on geological features, facies distribution and species habitats (Lurton and Lamarche, 2015).

As a result of the MapHab project, the successfully developed ‘best practice’ protocol describes the necessary steps from preparation through mapping activities to processing and interpretation of a benthic habitat map from central Disko Bay.

This project is coordinated by Greenland Institute of Natural Resources (GINR) and is funded by GINR, Miljøstøtte til Arktis (Dancea), Aage V. Jensens Fonde and the Ministry of Research in Greenland (IKIIN).
