Due to changing temperature regimes in the North- and the Wadden Sea, a fish survey in the Sylt Rømø bight (SRB) was established in 2007 for at least ten years. The aim is to investigate the Wadden Sea fish fauna with special interest in changes of migration behavior, species composition and feeding habits. Since 2021 an assessment of the epibenthic species in the net hauls was included. Seven stations are sampled monthly inside the SRB. Two additional stations, one outside the bight, one close to the Danish border are sampled as references four times a year. For sampling a mini bottom trawl, total length 17 m, trawl opening 7 m, height 3 m with a mesh size of 36 mm in the wings, 16 mm in the mid part and 6 mm in the cod end is used. At every station one haul in the water column and another at the bottom are sampled, for 15 minutes at a speed of approximately 2 knots. The data will help to give a more detailed picture of food chains and energy flows inside the Wadden Sea.
In order to monitor long-term variability in or eventual change of the planktonic community a quantitative analysis of meroplankton is ongoing since 1996 in the Sylt-Rømø Bight, a region of high ecological importance within the Marine Protect Area National Park Schleswig Holsteinisches Wattenmeer. Since 2014 the sampling is tightly linked to the LTER Sylt Roads time series thus enabling the coupling of species occurrence to the respective hydrochemical and physical conditions in the water column.

In order to monitor long-term variability in or eventual change of the planktonic community a semi-quantitative analysis of gelatinous zooplankton has been ongoing since 2009 in the Sylt-Rømø Bight, a region of high ecological importance within the Marine Protected Area National Park Schleswig Holsteinisches Wattenmeer. The sampling is tightly linked to the LTER Sylt Roads time series thus enabling the coupling of species occurrence to the respective hydrochemical and physical conditions in the water column.

In order to monitor long-term variability in or eventual change of the planktonic community a semiquantitative analysis of microplankton based on net sampling is ongoing since 1987 in the Sylt-Rømø Bight, a region of high ecological importance within the Marine Protect Area National Park Schleswig Holsteinisches Wattenmeer. The sampling is tightly linked to the LTER Sylt Roads time series thus enabling the coupling of species occurrence to the respective hydrochemical and physical conditions in the water column. These long-term data allow to quantify realized niches of frequently occurring micro-plankton species and to pinpoint rarely occurring species which cannot be detected in the quantitative plankton analysis.

The data help to get more detailed insight of food chains and energy flows in the Wadden Sea area. This compilation gives an overview of all datasets from the SRB fish survey for the period 2007 to 2020.
