Inproceedings Reference Food web structure of fouling communities along a depth gradient: a North Sea case study
Man-made structures offer habitat for sessile macrofauna and thus alter the natural biodiversity. This alteration has an impact not only on ecosystem structure, but also on ecological functioning, e.g. food web interactions. Trophic linkages among organisms are a fundamental requirement to explaining energy flow from primary carbon fixation to higher trophic level consumers and hence to explaining how man-made structures impact ecosystem functioning. The aim of this study is to disentangle trophic interactions within fouling communities at different depths of artificial hard substrates that are present in the Belgian part of the North Sea. Fouling organisms were collected along the entire depth gradient (from the intertidal zone down to the erosion protection layer) of a gravity-based windmill. Additionally, food sources, such as plankton, and mobile predators were sampled from the surrounding water column. All organisms were identified to the lowest possible taxonomic level and were processed for stable isotope analysis (δ15Ν and δ13C) to explore their trophic niche. This study reveals differences in food web structure to be aligned with the species richness turn across depths. The anticipated results will divulge the unique trophic linkages among hard substrate organisms opposed to the natural trophic interactions of soft substrate species in the North Sea. Disentangling trophic linkages between species, providing an idealized picture of the trophic patterns in the ecosystem is crucial to the understanding of marine food webs. This study hence provides fundamental insights into the functional effects of proliferating artificial hard substrates in marine ecosystems.

Inproceedings Reference PRELIMINARY STUDY OF THE WATER GRADIENT WITHIN A BELGIAN OFFSHORE WINDFARM
The FaCE-It project aims to examine the effects of sediment fining and hardening on benthic ecosystem functioning caused by anthropogenic impacts. Human activities, e.g. the construction of offshore windfarms, add artificial hard substrate to naturally soft sediments, altering the existing seabed habitats. The input of hard substrates leads to partial or entire replacement of the native benthic communities by fouling communities. The organisms comprising a fouling community act as active “biofilters” consuming organic compounds from the water column and releasing inorganic and organic materials, in the forms of faeces and pseudofaeces, to the surrounding environment – a procedure known as biodeposition. It is known that some fouling organisms, such as the amphipod Jassa herdmani and the hydroid Tubularia indivisa, build tube-like structures that absorb suspended particulate matter (SPM). These activities result in the alteration of the biogeochemical processes and could also lead to the SPM plumes that have been reported to occur in the Belgian offshore windfarms. The aim of the present study is to identify the alterations caused by fouling communities to the water characteristics and analyze the water gradient – flow of the water compounds according to the currents - around an offshore windfarm (C-Power) in the Belgian Part of the North Sea. The initial hypothesis is that organic and inorganic materials will flow according to the currents and will appear in different concentrations in front, within and behind the entire windfarm structure. For this purpose, a sampling campaign was organized in order to collect water samples from different areas of the windfarm and analyze them for a variety of water characteristics, such as chlorophyll a, suspended particulate matter, particulate organic carbon and nitrogen and dissolved organic carbon. The results of this study will present the concentrations of the water gradient occurring in the offshore windfarms due to the presence of the fouling community.

Inproceedings Reference Investigating geological processes and their links with geological structures through geomanifestations
GeoConnect³d introduced the concept of geomanifestations to define any distinct local expression of ongoing or past geological processes. These manifestations, or anomalies, often point to specific geologic conditions and, therefore, can be important sources of information to improve geological understanding of an area. Examples include seismicity, gas seeps, local compositional differences in groundwater and springs, thermal anomalies, mineral occurrences, jumps in hydraulic head, overpressured zones and geomorphological features. Geomanifestations are an addition to the structural framework model also being developed in GeoConnect³d, aiming to show where and how processes and structures may be linked. Data on geomanifestations are being collected in three areas: the Roer-to-Rhine area of interest in northwest Europe, and the Mura-Zala Basin and Battonya High within the Pannonian Basin area of interest in Eastern Europe. A first assessment of available data showed that groundwater-related geomanifestations in the form of anomalies in chemical composition (enrichment in elements such as Fe, or hydrocarbon gases and CO2,) or temperature (thermal water springs, geothermal anomaly in wells) are mappable in all areas. These geomanifestations point to special geological features in each area, such as proximity to magmatic reservoirs, presence of deep-rooted faults and considerable differences in the subsurface relief (trough–high system of the basement) among others. These anomalies at times define spatial patterns, which might or not be represented in the structural framework model, thus demonstrating whether they can be explained by the current geological understanding embedded in the structural framework. With this first test, we conclude that data on groundwater-related geomanifestations add to the robustness of the structural framework model. Further investigations with other types of geomanifestations are foreseen. This project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 731166.
