Pro Regione GmbH
Mapping and survey of marine growth by underwater video and benthos sampling in the area of the planned pier at Meierwik (Glücksburg)

A new pier is planned in the area of Meierwik near Glücksburg. A disturbance of the marine communities cannot be excluded by such a construction measure. MariLim GmbH was commissioned by Pro Regione GmbH to map the sublitoral area of Meierwik. Occurring macrophytes were mapped using underwater video footage. Benthic communities were sampled by divers. Analysis of the samples taken provides an overview of the existing species composition.

Muncipality of Scharbeutz
Survey (mapping) in the area of the piers at Scharbeutz and Haffkrug

The muncipality of Scharbeutz is planning to build two piers. MariLim GmbH is commissioned to investigate the sublittoral habitat around these piers at the beaches of Scharbeutz and Haffkrug. Divers collected samples of the macrozoo- and macrophytobenthos which were analyzed in our lab. Additionally, underwater videos were recorded, which provided the basis for the landscape management plan.

SWUP GmbH
Survey of marine growth and biotope mapping within the coastal area of Heiligenhafen by using underwater video technique

In the offshore sediment area off the sandspit “Steinwarder” near Heiligenhafen, the removal of stone groynes is planned once more within coastal protection measures. The project may affect the submarine area, which is part of the FFH area “Meeresgebiet der östlichen Kieler Bucht“ (FFH DE 1631-392). Therefore, an investigation of the planning area is required with respect to protected biotopes according to the Federal Act for the Protection of Nature (§ 30 BNatSchG) and the FFH habitat types.

Trüper Gondesen Partner mbB
Follow-up survey of marine growth and biotope mapping within the coastal area of Niendorf by using underwater video and fotography technique

In the offshore sediment area off Niendorf, sand fillings and removals as well as a renovation of the groynes were conducted within coastal protection measures. The old groynes were partly covered with bladder wrack (Fucus vesiculosus), which had to be preserved. The stones were thus put together to an area of hard substrate within the research area. One year after the completion of construction, the research area was investigated again via underwater videography and scuba diving to identify or exclude negative effects by the construction work, especially on the bladder wrack vegetation and eelgrass meadows.

ARSU GmbH
Survey of macrozoobenthos northwest of the island Juist to assess possible impacts due to working measures in the coastal area

In the offshore sediment area northwest off the island Juist, structures of the Norpipe pipeline owned by the company Gassco have been observed to be exposed. Since the island Juist is part of the Wadden Sea National Park, it has been necessary to record possible effects of the works on the macrozoobenthos, which may result e.g. from sediment flushing and a dryfall of working vessels.

Survey on potential areas of appearance of habitat type 1140 (LRT 1140) "vegetation free mud, sand and mixed mud flats" along the Baltic Sea coast in Schleswig-Holstein

A GIS-supported evaluation using the coastal line, the geomorphology and the position, plus a comparison with relevant technical bases was made for the identification of potential occurrences of the habitat type 1140 (LRT 1140) "vegetation free mud flats and sand flats", which naturally occur as windwatts (sea bed not covered by seawater due to wind action) on the coast of Schleswig-Holstein. In all fjords, deep inlets of the coast and inland lakes all the expanses of water were considered, which extend up to a water depth of 1 m and are large enough to be counted as a tidal area according to the habitat type LRT 1140.

State Agency for Agriculture, Environment and Rural Areas (LLUR)
As complement to the WFD monitoring in Schleswig-Holstein the makrophyte flora and fauna resident in the Schlei fjord are to be assessed, to discuss potential measures regarding improvement of the conditions

In addition to the monitoring program for macrophytes in Schleswig-Holstein 2017 (based on the requirements of the EU Water Framework Directive), the macrophyte-flora and fauna of the Schlei shall be investigated. Furthermore, the distribution and thickness of the Schlei’s digested sludge have to be assessed by means of geological analyses. Both data sets will be evaluated jointly to deduce possible measures for the improvement of the ecological status of the Schlei. MariLim GmbH will analyse sediment and macrozoobenthos from different transects throughout the Schlei by the use of a small bottom grab. The macrophytobenthos will be assessed at selected sampling stations via rake samples and an observation box which allows to observe the water body from boat. All samples will be analysed in the firm’s laboratory. The resulting data will be populated and processed in the MariLim data base and converted into GIS maps, which will be presented and evaluated in an advisory report.
