    Counts, density and biomass of copepod Harpacticoida found on <i>Cystoseira sp.</i> sampled at Calvi Bay (Corsica) between 02 and 10 September 1982. The data were digitized by VLIZ from the original report: Heip, C.H.R.; Willems, K.; Van hauwermeiren, G. (1983). Een systematisch-ecologische studie van Copepoda Harpacticoida levend op bruinwieren van het genus Cystoseira in de Baai van Calvi (Corsica), in: FKFO Project 2.9007.82. Systematiek en ecologie van mariene organismen: verslag over het tweede werkingsjaar 1983. pp. 43-58.

    Historical landings from the Venice (Italy) fish market for the period 1905-1927 (with some temporal gaps) were retrieved and transformed into workable spreadsheets from statistical bulletins published by the Municipality of Venice, the "Società regionale veneta per la pesca e l'acquicultura" (Veneto regional society for fisheries and aquaculture) and by the historical scientific journal called "Neptunia".

    The dataset was obtained from the original registers of the fish markets of Venice and Chioggia that were available on paper documents from 1945 to 1996, and in electronic spreadsheets from 1997. The data originally included information on landings from aquaculture and sea- and lagoon-fishery merged together.

    What ecological effects does a foreshore suppletion, and a beach suppletion, have on the marine ecosystem in the intertidal and shallow surf zone (<6 m depth)? The foreshore suppletion (400.000m³) was by means of an experimental set-up in the shallow coastal zone (-1 to -2m TAW) of Mariakerke. Beside it, a beach nourishment was conducted at Mariakerke (681243m³) and Middelkerke (968754m³). For the Mariakerke area, we collect biological and sedimentological samples in the impact area and in a control area (Bredene), before as after the suppletion, whereas for Middelkerke only the data after suppletion was part of the study. We monitor the marine ecosystem with a focus on the fauna within the sediment (macrofauna) and on the sediment (hyperbenthos, epi- and demersal fish fauna) in the intertidal zone and subtidal zone. In both studies, the subtidal area is the zone between the low water line and the 6m depth line and the intertdial area is the zone between low and high tide water line.

    Original provider: Duke Marine Robotics and Remote Sensing Lab Dataset credits: Duke Marine Robotics and Remote Sensing Lab Abstract: These RGB mosaics and thermal indices of Atlantic grey seal colonies at Hay and Saddle Island, Nova Scotia, were collected by small unmanned aircraft systems (UAS). The mosaics and thermal indices were assessed by human analysts, who counted the seals in the mosaic and classified individuals as 'young of the year' or 'adult'.

    Original provider: Giuseppe Notarbartolo di Sciara, Tethys Research Institute Dataset credits: Tethys Research Institute Abstract: The giant devil ray &lt;i&gt;Mobula mobular&lt;/i&gt;, the only Mediterranean mobulid, is subject to mortality caused by directed and accidental captures in fisheries throughout the region. Whilst the combination of human impacts, limited range and a low reproductive potential is not inconsistent with its endangered listing, there are insufficient data to enable a quantitative assessment of trends. Without this, it is difficult to assess and prioritise threats and develop effective conservation actions.
