To what extent can decommissioning options for marine artificial structures move us toward environmental targets?
-
Switching from fossil fuels to renewable energy is key to international energy transition efforts and the move toward net zero. For many nations, this requires decommissioning of hundreds of oil and gas infrastructure in the marine environment. Current international, regional and national legislation largely dictates that structures must be completely removed at end-of-life although, increasingly, alternative decommissioning options are being promoted and implemented. Yet, a paucity of real-world case studies describing the impacts of decommissioning on the environment make decision-making with respect to which option(s) might be optimal for meeting in- ternational and regional strategic environmental targets challenging. To address this gap, we draw together international expertise and judgment from marine environmental scientists on marine artificial structures as an alternative source of evidence that explores how different decommissioning options might ameliorate pressures that drive environmental status toward (or away) from environmental objectives. Synthesis reveals that for 37 United Nations and Oslo-Paris Commissions (OSPAR) global and regional environmental targets, experts consider repurposing or abandoning individual structures, or abandoning multiple structures across a region, as the op- tions that would most strongly contribute toward targets. This collective view suggests complete removal may not be best for the environment or society. However, different decommissioning options act in different ways and make variable contributions toward environmental targets, such that policy makers and managers would likely need to prioritise some targets over others considering political, social, economic, and ecological contexts. Current policy may not result in optimal outcomes for the environment or society.

A wind of change for soft-sediment infauna within operational offshore windfarms
-
In this study, “ artificial reef ” (AR) impacts of offshore windfarms (OWFs) on the surrounding soft-sediments were investigated. Benthic grab samples were collected at nearby (37.5 m) and distant (500 or 350 m) positions from turbines of two Belgian OWFs (Belwind: monopiles and C-Power: jackets). Higher macrobenthos abundance and species richness were found nearby jacket foundations of C-Power compared to distant positions and differences were most pronounced within deeper sediments (i.e., gullies between sandbanks) at intermediate levels of fine sand fractions (10 – 20%) and total organic matter (0.5 – 0.9%). Strong benthic enrichment ( > 1000 ind. m 2, > 20 spp. sample 1) was also linked with higher fine sand fractions ( > 20%) near the jackets. Moreover, nearby sediments showed higher occurrences of coastal species and habitat diversification was promoted by Mytilus edulis shell debris and alive organisms ( “ biofouling drop-offs ” ). The lack of similar results around monopiles (Belwind) confirms that the extent of detectable AR-effects depends on site- and turbine specific factors.

European plaice movements show evidence of high residency , site fidelity , and feeding around hard substrates within an offshore wind f ar m
-
Offshore wind farms (OWFs) are expanding rapidly in the North Sea, often creating spatial conflicts with fisheries. Managing such conflicts requires knowledge on the impact of OWFs on the spatial distribution and mo v ement beha viour of fished species. Ho w e v er, such kno wledge is still lacking, especially for soft sediment fish such as flatfish, which are vital fisheries resources in the region. T heref ore, w e used acoustic telemetry to examine the spatial behaviour of European plaice in relation to an OWF and its str uct ures. In a small study area (1.37 km 2 ), we observed high residency for plaice around the turbines and scour protection la y er (SPL), which consists of large rocks around the turbine foun- dation. The fish primarily resided on sandy sediments near the hard substrates, but sho w ed a diurnal pattern of proximity to the turbine, being closer during the day. Considering their trophic ecology, these findings suggest that plaice mo v es to w ards the SPL f or feeding opportunities on the hard substrate, potentially leading to increased ecological fish production within OWFs. Although most plaice mo v ed a w a y from the OWF in winter, lik ely to w ards spa wning grounds, man y e xhibited high site fidelity returning to the study area after the winter migration. OWFs thus offer protection from fishing mort alit y as “closed” feeding grounds in spring and summer, but not during winter spawning migrations, which may result in spillo v er effects. These insights should inform local fisheries management in relation to plaice movement within and around OWFs.

Northern Europe's suitability for offshore European flat oyster (Ostrea edulis) habitat restoration: A mechanistic niche modelling approach
-
1. After centuries of overexploitation, European flat oyster (Ostrea edulis) habitats are increasingly being protected and large-scale oyster habitat restoration projects have been initiated in the North Sea, the English Channel, the Irish Sea and the north-eastern Atlantic. 2. Understanding the habitat requirements of flat oysters is key in the selection process of restoration sites. 3. In this study, a theoretical niche for all life stages of the flat oyster is determined using a dynamic energy budget model forced with temperature, chlorophyll a and salinity in combination with sediment composition. The suitability of Northern Europe's marine environment for flat oysters is evaluated by applying the proposed niche model on a spatial scale and evaluating spatio-temporal variability in life history traits and metabolic characteristics, such as fitness, reproductive output, settlement success and growth. 4. Results show that habitat suitability is limited by low maximum summer temperature and low food availability at higher latitudes and in areas under strong influence of the Atlantic Ocean. Restoration efforts in Ireland and Scotland should be confined to protected and shallow coastal environments. Suitability in the southern North Sea is patchy and mainly depends on seabed substrate. The nearshore areas of the English Channel are highly suitable. 5. The georeferenced dataset shared in this study will be useful for restoration practitioners.
