Description

On behalf of Mowi Seawater ASA has Aqua Kompetanse AS conducted a survey of vulnerable species and habitats in shallow waters (0–50 m) and deep waters (>50 m). The purpose of the survey is to identify the presence and observed density of vulnerable species that may form habitats listed on the Norwegian Red List for Ecosystems and Habitat Types (Artsdatabanken, 2018), on OSPAR’s list of threatened and/or declining habitats (OSPAR 2008-06, revised in 2021), and among the proposed management-relevant habitat types for fisheries and aquaculture (Institute of Marine Research Report, 2024-16). At depths greater than 50 meters, the focus is mainly on corals, sponges, and sea pens. However, other red-listed and/or vulnerable species that live in close interaction with the three-dimensional habitats formed by the aforementioned groups will also be described when relevant. At depths shallower than 50 meters, the survey includes kelp forests, soft-bottom shoreline areas, coarse substrate bottoms, marine seagrass beds, exposed blue mussel beds, oysters, scallop populations, corals, sponges, sea pens, and any other red-listed shallow-water species. The investigation is based on the Institute of Marine Research’s proposed methodology for surveying vulnerable species and habitats in deep water (>50 meters depth) in connection with applications for marine aquaculture (Kutti and Husa 2021) or on the recommended methodology from the fishing and environmental directories (2022).

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 2,263 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Method step description:

  1. Equipment: Aqua Kompetanse AS normally uses an Aegir 50 ROV from Ocean Robotics, equipped with a minimum of 3 x 3500 lumen LED lights, an HD camera with zoom, and Advanced Navigation underwater positioning with an accuracy of 1.5 meters per 100 meters. The positioning system is connected to a GNSS antenna from Advanced Navigation. The size of observed objects is measured using a mounted laser with two fixed beams spaced 50 mm apart. The type of ROV used is selected based on the survey area, depth, and logistical considerations. All equipment used meets, at a minimum, the baseline requirements specified by Kutti and Husa (2021 and 2022).
