Description

This dataset provides species occurrence records from a biodiversity survey of low-trophic aquaculture sites cultivating blue mussels (Mytilus edulis), carried out within the COOL BLUE project. Records were obtained using two complementary monitoring approaches: eDNA metabarcoding, based on water samples and Autonomous Reef Monitoring Structures (ARMS) bulk samples, and baited remote underwater video (BRUV).For the BRUV approach, the associated video data were also used to train a machine learning model to identify the recorded taxa. Further information on the methodology and procedure is available here.

Data Records

The data in this sampling event 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 20 records.

1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Project Data

Cool Blue Future promotes community-led regenerative ocean farming in the Baltic and North Seas through projects like COOL BLUE and COOL BLUE BALTIC. These initiatives focus on low-trophic cultivation, ecosystem restoration, and local job creation. By emphasising education, community activism and business development, they aim to transform ocean farming into a regenerative, community-driven industry.
