Fugro strengthens presence in Norway’s 2024 MAREANO programme for seabed mapping
Fugro has completed the survey work for the 2024 MAREANO seabed mapping programme, introducing an innovative environmental DNA (eDNA) service as part of a hydrographic survey contract from the Norwegian Hydrographic Service (NHS). Supported by the Norwegian central government, MAREANO is a multidisciplinary effort focused on mapping the seabed to provide crucial scientific insights for the sustainable management and conservation of Norway’s marine resources.
This year’s survey encompassed a vast 2,823km² area in the North Sea, with depths ranging from 146 to 337 metres. Using the Fugro Discovery, equipped with high-resolution multibeam echosounders and sub-bottom data acquisition systems, the objective was to gather a seamless dataset, integrating bathymetry, water column and acoustic backscatter data.
Fugro employed cutting-edge sensors and advanced calibration techniques tailored to these challenging conditions. The survey was completed in September and work is now progressing on the final reports and data that will be available via VirGeo, Fugro’s web-based geodata platform.
Need for marine knowledge
In a first for the programme, Fugro included environmental DNA (eDNA) sampling as part of the survey datasets. This approach provides valuable insights into biodiversity and community composition, which are essential for projects aiming for net biodiversity gain and for monitoring endangered and invasive species. eDNA enhances existing environmental sampling programmes to gain deeper ecological insights, complementing other survey activities such as metocean, geophysical and geotechnical surveys.
Furthermore, Fugro collected transit data for NHS to share with the European Marine Observation and Data Network (EMODnet). This data will contribute to The Nippon Foundation-GEBCO Seabed 2030 Project, which aims to map the world’s entire ocean floor by 2030.
“The last few years, the MAREANO programme has placed emphasis on the North Sea. There is a need for marine knowledge in areas considered as particularly valuable and vulnerable. This marine knowledge is also relevant for the new marine industries – such as offshore wind and offshore aquaculture,” said Nicolien Haasbroek, project engineer for MAREANO in the Norwegian Mapping Authority.
Marc Kebbel, Fugro’s service line director hydrography for Europe and Africa, stated: “MAREANO is the largest multidisciplinary mapping programme of its kind in Norway and we are excited to continue our support for the project. Our knowledge of the marine environment and innovative techniques allow us to collect high-quality geodata that deepens our understanding of the seafloor and supports scientific discoveries; to keep our oceans healthy and help manage them sustainably.”
Fugro has a track record of conducting successful surveys for the programme since 2006. To date, Fugro has acquired over 140,000km2 of data under the programme, which has helped Norway improve its understanding of its marine environment and resources.
