Article Reference Turbid wakes associated with offshore wind turbines observed with Landsat 8

Techreport Reference Turbine size impacts the number of seabird collisions per installed megawatt and offers possibilities for mitigation.
As the offshore wind energy technology is rapidly progressing and because wind turbines at sea have a relatively short life span, repowering scenarios are already being discussed for the oldest wind farms. Ongoing developments result in larger wind turbines and an increased open airspace between turbines. Despite taller towers having larger rotor swept zones and therefore a higher collision risk area compared to smaller-sized turbines, there is increasing evidence that fewer but larger, more power-efficient turbines may have a lower collision rate per installed megawatt. As such, turbine size can offer an opportunity to mitigate seabird fatalities by increasing the clearance below the lower rotor tip. We assessed the seabird collision risk for a hypothetical repowering scenario of the first offshore wind farm zone in Belgian waters with larger turbines and the effect of an additional increase in hub height on that theoretical collision risk. For all species included in this exercise, the estimated collision risk decreased in a repowering scenario with 15 MW turbines (40.4% reduction on average) because of higher clearance between the lower tip of the turbine rotor and the sea level, and the need for a lower number of turbines per km². Increasing the hub height of those 15 MW turbines with 10 m, further decreases the expected number of seabird collisions with another 37% on average. However, terrestrial birds and bats also migrate at sea and the effect of larger turbines on these taxa is less clear. Possibly even more terrestrial birds and bats are at risk of collision compared to the current turbines. So, while larger turbines and increasing the hub height can be beneficial for seabirds, this likely needs to be applied in combination with curtailment strategies, which stop the turbines during heavy migration events, to reduce the impact on other species groups.

Article Reference Two celebrations and the Sustainable Development Goals
This year 2023, we have two milestones to celebrate for Hydrobiologia. Firstly, as Hydrobiologia was launched in March 1948, our journal is now 75 years young. Secondly, this is the first issue of volume 850. The second celebration requires a little nuance. Up to and including 2019, each of the 21 issues of Hydrobiologia was considered a separate volume and we ended 2019 with volume 846. Since 2020, Springer Nature standardized its journal portfolio in that one volume now covers a full year. For Hydrobiologia this means that we now have one volume and 21 issues annually. If the publication schedule would have remained unchanged, we would have started 2023 with volume 910 and we would have celebrated volume 1000 in 2027! Now we will have to wait 150 years to celebrate that event, in 2183 no less!

Article Reference Two new non-marine species of the subfamily Cypridopsinae Kaufmann, 1900 (Crustacea, Ostracoda) from sourthern Africa
Two new Cypridopsinae ostracods, Potamocypris meissneri sp. nov. and Sarscypridopsis harundineti sp. nov. are described. Both were found only as asexual (all-female) populations in temporary waters of southern Africa. Potamocypris meissneri was collected from a small pan in the North-West Province of South Africa. It is approximately 0.5 mm long and belongs to the species group with long swimming setae on the second antennae. However, the species has a somewhat isolated position in the genus owing to the conspicuously reticulated carapace, which is furthermore densely covered by prominent conuli with normal pores carrying long sensilla, as well as to the wide anterior and posterior flanges on the left valve. To allow identification of the new species in relation to its closest congeners, a key to the species of the genus Potamocypris Brady, 1870 from southern Africa is provided. The genus Sarscypridopsis McKenzie, 1977 mostly has an Afrotropical distribution with only few species occurring in other regions. Sarscypridopsis harundineti was collected from floodplains of the outskirts of the Okavango Delta in Botswana. It is approximately 0.4 mm long and can be distinguished from congeners mainly by the smaller and more oval-shaped valves. We conclude that southern African Cypridopsinae urgently need integrated taxonomic revision, by means of both morphological characters and DNA-sequence data.
