    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: 〈jats:p〉Abstract. Systematic long-term studies on ecosystem dynamics are largely lacking from the East Antarctic Southern Ocean, although it is well recognized that they are indispensable to identify the ecological impacts and risks of environmental change. Here, we present a framework for establishing a long-term cross-disciplinary study on decadal timescales. We argue that the eastern Weddell Sea and the adjacent sea to the east, off Dronning Maud Land, is a particularly well suited area for such a study, since it is based on findings from previous expeditions to this region. Moreover, since climate and environmental change have so far been comparatively muted in this area, as in the eastern Antarctic in general, a systematic long-term study of its environmental and ecological state can provide a baseline of the current situation, which will be important for an assessment of future changes from their very onset, with consistent and comparable time series data underpinning and testing models and their projections. By establishing an Integrated East Antarctic Marine Research (IEAMaR) observatory, long-term changes in ocean dynamics, geochemistry, biodiversity, and ecosystem functions and services will be systematically explored and mapped through regular autonomous and ship-based synoptic surveys. An associated long-term ecological research (LTER) programme, including experimental and modelling work, will allow for studying climate-driven ecosystem changes and interactions with impacts arising from other anthropogenic activities. This integrative approach will provide a level of long-term data availability and ecosystem understanding that are imperative to determine, understand, and project the consequences of climate change and support a sound science-informed management of future conservation efforts in the Southern Ocean. 〈/jats:p〉
