AbstractThe expanding development of offshore wind farms brings a growing concern about the human impact on seabirds. To assess this impact a better understanding of offshore bird abundance is needed. The aim of this study was to investigate offshore bird abundance in the breeding season and model the effect of temporally predictable environmental variables. We used a bird radar, situated at the edge of a wind farm (52.427827° N, 4.185345° E), to record hourly aerial bird abundance at the North Sea near the Dutch coast between May 1st and July 15th in 2019 and 2020, of which 1879 h (51.5%) were analysed. The effect of sun azimuth, week in the breeding season, and astronomic tide was evaluated using generalized additive modelling. Sun azimuth and week in the breeding season had a modest and statistically significant (p < 0.001) effect on bird abundance, while astronomic tide did not. Hourly predicted abundance peaked after sunrise and before sunset, and abundance increased throughout the breeding season until the end of June, after which it decreased slightly. Though these effects were significant, a large portion of variance in hourly abundance remained unexplained. The high variability in bird abundance at scales ranging from hours up to weeks emphasizes the need for long-term and continuous data which radar technology can provide.

Abstract Preliminary design and feasibility investigation of a 2-MW wind turbine for offshore wind farm operation are presented in this study. A region in the North Sea, to the west of the West Frisian Islands offshore of Dutch coast is selected as a potential wind farm site due to its high availability of wind resources. Based on the wind data of the selected site and operating requirements of the wind farm, preliminary sizing and conceptual design of wind turbine rotor blades are carried out. Performance of the rotor design is first assessed by classical blade element-momentum theory, followed by state-of-the-art commercial CFD software. Economics and feasibility analysis of this wind turbine operating in an offshore wind farm setting is conducted using DOE/NREL scaling cost model. The feasibility investigation results reveal that the cost of energy (COE) for operating the current wind turbine design at the selected wind farm site is considerably lower than the average COE in the Netherlands, indicating high potential of commercially making profits. Environmental impact studies have also been done.

&lt;p&gt;The production of renewable offshore wind energy in the North Sea increases rapidly, including development in ecologically significant regions. Recent studies identified implications like large-scale wind wake effects and mixing of the water column induced by wind turbines foundations. Depending on atmospheric stability, wind wakes imply changes in momentum flux and increased turbulence up to 70 km downstream, affecting the local conditions (e.g. wind speed, cloud development) near offshore wind farms. Atmospheric wake effects likely translate to the sea-surface boundary layer and hence influence vertical transport in the surface mixing layer. Changes in ocean stratification raise concerns about substantial consequences for local hydrodynamic and biogeochemical processes as well as for the marine ecosystem.&lt;br&gt;Using newly developed wind wake parametrisations together with the unstructured-grid model SCHISM and the biogeochemistry model ECOSMO, this study addresses windfarming impacts in the North Sea for future offshore wind farm scenarios. We focus on wind wake implications on ocean dynamics as well as on changes in tidal mixing fronts near the Dogger Bank and potential ecological consequences. At this, we create important knowledge on how the cross-scale wind farm impacts can be modelled suitably on the system scale.&lt;/p&gt;
