Circalittoral faunal turfs are animal-dominated shelf assemblages that are found on hard substrata between the lower limit of the infralittoral zone and the shelf edge. Benthic organisms generally form dense intricate mixes that may include tall alcyonarians, sponges, hydroids, scleractinians and gorgonians, as well as less prominent fauna such as encrusting sponges, bryozoans, ascidians, bivalves, solitary cup corals, serpulid worms and vermetid gastropods.

Rhodoliths is a general term used to designate non-geniculate coralline red algae (Rhodophyta) that live unattached (Riosmena-Rodríguez, 2017). The term is used here to encompass (i) branched free-living coralline algae devoid of an evident nucleus, but also (ii) nucleated nodules where the biogenic calcium carbonate deposit around the core represents >50%, as well as (iii) “coated grains” where the core is larger than the algal carbonate component.

Black corals are antipatharian corals that occur from sublittoral to abyssal depths on hard, mixed and soft substrates. Under favourable conditions, some black coral species form dense stands known as black coral gardens which create habitat for a variety of associated species.

<p>Plankton observations along the South Brazilian Shelf, with a focus on the Cabo Frio Upwelling System. The sampling was done using images generated by an in-situ imaging device, the Lightframe On-Sight Key Species Investigation (LOKI): An underwater camera system designed for vertical hauls for continuous, in-situ imaging of zooplankton. It is equipped with an environmental sensor (CTD) that measured the density of the water column, salinity, oxygen concentration and temperature.</p>

The European plaice (Pleuronectes platessa) nursery grounds dataset is derived from the existing (Trimoreau et al, 2013) nursery ground map available in the Sextant Ifremer data catalogue. (Trimoreau et al, 2013) nursery ground dataset has been modified in order to comply with the standard format developed by the EMODnet Seabed Habitats Lot. In that EMODnet format, the map key classifies areas as ‘high’, ‘medium’, and 'low' suitability. The juvenile density values provided in (Trimoreau et al, 2013) dataset have been used to classify areas as ‘high’, ‘medium’, and 'low' suitability.

The common sole (Solea solea) nursery grounds dataset is derived from the existing (Trimoreau et al, 2013) nursery ground map available in the Sextant Ifremer data catalogue.
