Description: Driven by climate change, marine biodiversity is undergoing a phase of rapid change that has proven to be even faster than changes observed in terrestrial ecosystems. Understanding how these changes in species composition will affect future marine life is crucial for conservation management, especially due to increasing demands for marine natural resources. Here, we analyse predictions of a multiparameter habitat suitability model covering the global projected ranges of 〉33,500 marine species from climate model projections under three CO2 emission scenarios (RCP2.6, RCP4.5, RCP8.5) up to the year 2100. Our results show that the core habitat area will decline for many species, resulting in a net loss of 50% of the core habitat area for almost half of all marine species in 2100 under the high-emission scenario RCP8.5. As an additional consequence of the continuing distributional reorganization of marine life, gaps around the equator will appear for 8% (RCP2.6), 24% (RCP4.5), and 88% (RCP8.5) of marine species with cross-equatorial ranges. For many more species, continuous distributional ranges will be disrupted, thus reducing effective population size. In addition, high invasion rates in higher latitudes and polar regions will lead to substantial changes in the ecosystem and food web structure, particularly regarding the introduction of new predators. Overall, our study highlights that the degree of spatial and structural reorganization of marine life with ensued consequences for ecosystem functionality and conservation efforts will critically depend on the realized greenhouse gas emission pathway.

Semi-quantitative records of benthic taxa from trawl samples taken in the wider Weddell Sea (Antarctica) during POLARSTERN cruises ANT VII/4, ANT IX/3, ANT XIII/3, ANT XV/3 and ANT XXI/2 between 1989 and 2004 (2020)

Description: The dataset comprises a total of 9,540 records of semi-quantitative data for 53 benthic invertebrate taxa and fish from 180 trawl samples (Agassiz trawl, bottom trawl, Rauschert dredge, benthopelagic trawl). The semi-quantitative data represent four categories regarding the frequency of occurrence of the benthic taxa (i.e. 0 = absent, 1 = rare, 2 = common and 3 = very common). The dataset was collected on the shelf and slope of the eastern Weddell Sea and Lazarev Sea, near Bouvet Island and the region at the north western tip of the Antarctic Peninsula (depth range: 64 - 2334 m) between 1989 and 2004 onboard "Polarstern". Cruises ANT VII/4 (1989), ANT IX/3 (1990/91), ANT XIII/3 (1996), ANT XV/3 (1998) and ANT XXI/2 (2003/2004) contributed to the data collection.

Description: Makrozoobenthos of soft-bottom benthic communiy was collected by van-Veen grabs and beam trawls to sample the infauna and epifauna. Samples were collected between 2003 and 2004 in spring, summer and autumn each year. Benthic data were collected in the North Sea, German Bight off the East Frisian Coast. Benthic community was evaluated for potential changes after cessation of bottom trawling. In July 2003, the research platform FINO 1 was built as a pilot project for future offshore wind farms. The platform is located at 28 m water depth in the German Bight, 45 km off the Island Borkum. The surroundings of the platform (500 m radius) are closed for all shipping activities (except scientific activities) and are thus protected from trawling activities. Two zones beyond the 500 m radius, 9 km apart from the protected area in north-western and eastern direction were chosen as reference sites. Sampling follwed a BACI-design (before-after-control-impact), i.e. comparing the protected area to the further trawled areas. In both areas, protected and trawled area, sampling of the benthic community was carried out with “RV Heincke” during 2 periods. The first sampling period, defined as “pre-closure”, includes two sampling campaigns: one campaign 3 months before and one campaign 2 weeks after fishery closure of protected area (March/April and July/August 2003). “Post-closure” sampling was also carried out in two campaigns: one campaign in July/August and one campaign in September/October 2004, i.e. 12-14 months after fishery closure of protected area. Data for each campaign comprise different stations in the area, sampled by grab samples (infauna) and beam trawl samples (epifauna). Biodiversity data of species include abundance (count data) and biomass (wet mass, g) per sample, as well as sediment grain sizes, organic carbon, total carbon, nitrogen and sulfur content as accompanying environmental data.

Description: Concentrations of scavengers attracted by bait in the deep sea are documented by time-lapse photography and results of baited traps. During a remotely operated vehicle deployment in the Molloy Deep, the deepest depression of the Fram Strait, the carcass of a natant decapod, Pasiphaea tarda Krøyer, 1845, was discovered at 79°08.4'N and 002°49.85'E in a depth of 5,551 m. The carcass was covered by hundreds of individuals of Uristes sp., a scavenging lysianassoid amphipod. After documentation of this event, both the carcass and the majority of amphipods were collected. This is the first reported observation and sampling of an ongoing feeding process of scavengers on a natural food fall in the deep sea.

Description: The PAN-Arctic data collection of benthic BIOtas (PANABIO) contains records of benthic fauna identified at genus-level or species-level in field samples taken at point-referenced locations (stations) by means of grabs, towed gear, or seabed imaging. The data are from all major marine Arctic areas, i.e., central Arctic Ocean, Chukchi Sea, East Siberian Sea, Laptev Sea, Kara Sea, Barents Sea (incl. White Sea), Svalbard waters, Greenland Sea, Norwegian Sea, Canadian Archipelago, Beaufort Sea, and Bering Sea, as well as some adjacent sub-Arctic regions (Sea of Japan, Gulf of Okhotsk). Currently (14 December 2023), the collection includes 27 datasets with a total of 126,388 records (ranging from presence to counts, abundances or biomass) of 2,978 taxa, identified in 11,555 samples taken at 10,596 stations during 1,095 cruises between 1800 and 2014. It is also available in a PostgreSQL-based data warehouse that can be accessed and queried through an open-access frontend web service at https://critterbase.awi.de/panabio.
