Target status assessment of the macrozoobenthos and fishes at the sites "Schwarztonnensander Nebenelbe", "Barnkruger Loch" and "Uferschlenze at Asseler Sand" within the period 2022–2023
Project start

Within the framework of compensation procedures for the fairway adjustments in the lower and outer river Elbe, the Wasserstraßen und Schifffahrtsamt Elbe-Nordsee (Elbe-North Sea Waterway and Shipping Authority) as the executing body is responsible for the preservation of evidence and monitoring of compensation success. MariLim GmbH conducts the required laboratory work for the survey of target condition regarding macrozoobenthic organisms and evaluates the assembled data via the method “Aestuar-Typie-Index” (Aestuary-typing-index) according to KRIEG (2005).

WSA Ostsee
Expert report on benthos as part of preservation of evidence during the expansion of the seaward access to the Rostock seaport
Project start

The Federal authority for waterways and shipping in the Baltic Sea (WSA Ostsee), location Stralsund is planning the expansion of the sea channel Rostock up to Sea level (German: Normalhöhennull, NHN) -16.10 m to -16.80 m aiming to allow bulk carriers with 15 m draught access to the harbour and support a better capacity for the ships already present.

To describe the current state of the macrozoobenthos grab samples were taken at two transects in spring 2021. At the same transects three consecutive monitorings (directly after excavation, first and third year after dredging) will be performed to determine possible shifts in the macrozoobenthos due to construction related turbidity plume and to record the temporal development.

Expert report on benthos (according to the national standard operational procedure StUK4) for the impact assessment of the offshore wind mill farm “Cluster westlich Adlergrund” – operation monitoring 3rd year for "Arkona-Becken Südost" and 5th year for "Wikinger"
Project start

The wind farms „Wikinger“ and „Arkona-Becken Südost“ are part of the wind farm Cluster “westlich Adlergrund” and are operated since 2017 and 2019, respectively. The wind farm „Wikinger“ is operated by Iberdrola Renovables Offshore Deutschland GmbH, „Arkona-Becken Südost“ by RWE Renewables GmbH. The wind farms are situated in the southern Baltic Sea, approx. 35 km north east of the island of Rügen.

According to the specifications of the Federal Maritime and Hydrographic Agency, the operating phase has to be biologically monitored. This monitoring and the assessment reveal and evaluate the possible impacts of the operating wind farms on benthic organisms.

The biological monitoring is perfomed by the MariLim GmbH and includes surveys with a Van-Veen-grab for infauna, and dredge lines and video surveys for epifauna within the area of the wind farms as well as within an adequate reference area. Additionally, scientific divers take scratching samples at the underwater structures of the wind farms “Wikinger” and “Arkona-Becken Südost” according to the specifications of the Federal Maritime and Hydrographic Agency. All sample will be fixed and processed in the laboratories of the MariLim GmbH. Resulting data will be saved in a database and form the basis for the analyses of the assessment report.

Plausibility check of the biotope mapping regarding the marine gravel-sand deposit "Warnemünde Ost" of 2015

In 2015, the company MariLim GmbH carried out a macrozoobenthos and biotope mapping in the planned gravel mining area "Warnemünde Ost" on behalf of INROS LACKNER SE for the company André Voss Erdbau & Transport GmbH Rostock (Kuhlmann & Meyer 2015). In 2019 this gravel sand deposit was taken over by the company Kiese und Sande Ostsee GmbH. Since the mapping in 2020 was five years ago, it is necessary to check that the database is up to date. Against this background, the company Kiese und Sande Ostsee GmbH commissioned a plausibility check of the database for "Warnemünde Ost".
As part of the plausibility check, two sub-areas (approval fields BW I and BW II) are considered. For the company Kiese und Sande Ostsee GmbH, the sub-area BW I is particularly relevant. The sub-area BW II was abandoned due to the results from 2015 and should not be considered further. In the summary of the biotope mapping 2015, the sub-area BW II is included for the sake of completeness, but not included in the plausibility check. When assessing the sub-area BW I, only data from the literature are used.

Water and Shipping Authority Stralsund
Expert report on benthos for the impact assessment of the expansion/deepening of the waterway to port Rostock
Project start 2016

The Waterways and Shipping Office Stralsund is planning the expansion of the sea channel Rostock up to Sea level (German: Normalhöhennull, NHN) -16.xx m. The aim is to allow bilk carriers with 15 m draught access to the harbour and support a better capacity for the ships already present.

As basis for the environmental impact study (German: Umweltverträglichkeitsuntersuchung, UVU) and to check for regulations related to preservation of species ecological, accompanying investigations for recording the macrozoobenthos community shall be performed.

For this grab samples were taken at 28 stations (Seekanal, Breitling, Klappstellen-Erweiterung) in spring and autumn 2016. With the resulting data the actual state of the macrozoobenthos in the relevant area and the direct active sphere are supposed to be surveyed and described.

Mapping of benthic biotopes at a proposed sand and gravel extraction site "Warnemünde East"
Project start 2013

The company Firma Andre’ Voß Erdbau und Transport GmbH is planning to build a gravel extraction site northeast of Warnemünde. The company MariLim GmbH performs investigations on the benthos, an object of legal protection, according to the specifications of the Federal Maritime and Hydrographic Agency (Bundesamt für Seeschifffahrt und Hydrographie, BSH) within the approval procedure. These investigations serve as basis for the required environmental and nature conversational documents such as environmental impact assessment, landscape conservation plan and expert contribution on species protection.

Thereby, several ecological parameters of the macrozoobenthos (e.g. population density, biomass, diversity) and macrophytobenthos in the area of the gravel extraction site are identified and analysed. By these parameters the benthic communities are characterized.

Expert report on benthos and fish (according to the national standard operational procedure) for the impact assessment of the offshore wind mill farm “Nordsee-Ost”

In autumn 2012, the company RWE Innogy GmbH started to build the offshore wind farm “Nordsee One” with 48 turbines in the German North Sea, north of Helgoland. On the basis of the Standards for Environmental Impact Assessments (German: Standarduntersuchungskonzepts, StuK3) a construction phase monitoring is required, which covers the time period from the beginning of the construction until its ending. The investigations serve as supervision of the construction phase or rather for the medium and small scale recording of relevant effects by the construction works on the benthos, an object of legal protection, and its seasonal development. To that, in autumn 2012, i.e. immediately after starting the construction works, and in spring 2013 samples of in- and epifauna, as well as samples of sediment were taken and analysed.

Project start 2010

In August 2013, the company EWE Netz GmbH laid a submarine cable between the East Frisian island of Borkum and the mainland at Mansgalt, i.e. through the National Park “Niedersächsiches Wattenmeer”. The National Park “Niedersächsiches Wattenmeer” has been confirmed as FFH area 2306-301 (German: FFH-Gebiet) and therefore includes a majority of protected FFH habitat types. Within the plant license by the local authority (Niedersächsischer Landesbetrieb für Wasserwirtschaft, Küsten- und Naturschutz, NLWKN) of 4. April 2012 it has been set, that under the construction phase a monitoring has to be performed, with respect to the protected fauna of the benthos. According to this, once a year samples were taken along the alignment from 2010 to 2014.
