The Green Edge project was designed to investigate the onset, life and fate of a phytoplankton spring bloom (PSB) in the Arctic Ocean. The lengthening of the ice-free period and the warming of seawater, amongst other factors, have induced major changes in arctic ocean biology over the last decades. Because the PSB is at the base of the Arctic Ocean food chain, it is crucial to understand how changes in the arctic environment will affect it. Green Edge was a large multidisciplinary collaborative project bringing researchers and technicians from 28 different institutions in seven countries, together aiming at understanding these changes and their impacts on the future. The fieldwork for the Green Edge project took place over two years (2015 and 2016) and was carried out from both an ice camp and a research vessel in the Baffin Bay, Canadian arctic. Here, we describe the data set obtained during the research cruise, which took place aboard the Canadian Coast Guard Ship (CCGS) Amundsen in spring 2016. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

A geotechnical survey campaign was undertaken within the vicinity of the Westermost Rough Offshore Wind Farm. This was supported by a preliminary review of acoustic data and assessment for the presence of Annex I reefs to minimise the risk of potential damage to protected features. Following the review of existing data, a drop down video survey protocol was developed (EMU, 2011) and approved by the Marine Management Organisation (MMO). Part of this protocol identified that a number of proposed geotechnical sampling sites were likely to be in the vicinity of potential Annex I reefs and therefore warranted field ground-truthing by means of drop down video to verify the presence and status of these features. The video ground-truthing survey has now been completed. Drawing upon the findings of this survey, the 2012 EMU report present within this series provides an update of the assessment of the potential Annex I reefs present at the proposed geotechnical sample locations and fulfils condition 3.1.1 of the Marine Licence (Licence L/2011/001075). The aim of the 2013 Fugro EMU document also present within this series was to satisfy Marine Licence condition 31.22 and to address the responses from the MMO regarding the Annex I reef features (letter ref: REN024, dated 12th April 2013, and 21st June 2013). The objectives were to assess the impacts (direct and indirect) of the construction activities on the potential Annex I features. The objectives of this report were to: 1. Assess the direct impact (loss of habitat) of each of the construction activities; 2. Assess the associated indirect impacts (increase in sediment smothering, and suspended sediment concentrations. 3. Assess the cumulative impacts of all construction activities.

The Institute of Estuarine and Coastal Studies (IECS) was commissioned by Forewind Ltd to carry out a Phase 1 biotope survey of the intertidal zone located between the towns of Redcar and Marske-by-the-Sea, Tees estuary, Teesside. This area has been identified as a preferred landfall location for export cables, with the ultimate aim of connecting offshore wind farms off the Teesside coastline to the National Grid. The intertidal survey was completed as part of the development of the Environmental Impact Assessment (EIA) required from Forewind Ltd to continue with the proposal to use this area as a landfall site.

Lewis Wave Power Ltd. (LWP) (a wholly owned subsidiary of Aquamarine Power Ltd.) was seeking to develop a wave energy demonstration array off the west coast of the Isle of Lewis. As a first stage of the Environmental Impact Assessment (EIA) for the project, LWP commissioned Royal Haskoning Ltd. to produce an Environmental Scoping Report (Lewis Wave Power Ltd., 2011) to facilitate the identification and assessment of the potential environmental impacts associated with the project. The survey reported on here formed this field-based benthic component. Its purpose was to provide site-specific benthic data to inform an assessment of impact of the proposed development. The key objectives were to: Determine the distribution and abundance of marine habitats and communities within the study areas; Determine the substrate type at all locations sampled and Identify habitats or species of conservation importance.

The dataset provides full-coverage maps of the habitats and biotopes in the German Baltic Sea at a resolution of 1 x 1 km for the entire region and at 50 x 50 m resolution in specific areas. We combined geological and biological surveys to map the seabed and collected extensive data to classify different habitats and their associated benthic communities. Using newly established national guidelines and predictive habitat modelling, we produced highly accurate maps. The maps show Broad and Other Habitat Types (including Habitats Directive Annex I habitat types) according to the Marine Strategy Framework Directive (MSFD) as well as HELCOM HUB biotope types.

Coralligenous and Rhodolith beds found in Oceana expeditons between 2006 and 2020

List of macroinvertebrate taxa found in Sacharina latissima and Alaria esculenta cultivated on longlines. Objectives within WP6 of GENIALG: assessing the biodiversity associated with cultivated seaweed. Location of seaweed farm: Ventry Harbour, Ireland. Dataset consists of macroinvertebrate taxa identified and enumerated from 25 cm replicate seaweed samples removed from the longlines. The samples were collected at seven different time points along the growing season in 2018 and 2019. Samples collected as part of the GENIALG project (project ID: 727892, GENIALG - GENetic diversity exploitation for Innovative Macro-ALGal biorefinery, http://genialgproject.eu/). GENIALG was funded by the European Union Horizon2020 programme. The remit of the work was assessing the environmental footprint and ecosystem services provided by seaweed aquaculture in Europe to provide best practice advice to industry.
