Zoobenthos and sediments time series in southern Königshafen, Sylt, Germany, in 2003

In parallel to an ongoing time series in the subtidal of List Reede, 12 fixed sites were sampled in the adjoining intertidal area between September 2003 and June 2012. Analyses comprised abundances and species composition of macrozoobenthos (sieve size 1 mm) and granulometric sediment composition. This dataset contains the results from two sampling dates in 2003.

Zoobenthos and sediments time series in southern Königshafen, Sylt, Germany, in 2005

In parallel to an ongoing time series in the subtidal of List Reede, 12 fixed sites were sampled in the adjoining intertidal area between September 2003 and June 2012. Analyses comprised abundances and species composition of macrozoobenthos (sieve size 1 mm) and granulometric sediment composition. This dataset contains the results from ten sampling dates in 2005.

Zoobenthos and sediments time series in southern Königshafen, Sylt, Germany, in 2007

In parallel to an ongoing time series in the subtidal of List Reede, 12 fixed sites were sampled in the adjoining intertidal area between September 2003 and June 2012. Analyses comprised abundances and species composition of macrozoobenthos (sieve size 1 mm) and granulometric sediment composition. This dataset contains the results from six sampling dates in 2007.

Zoobenthos and sediments time series in southern Königshafen, Sylt, Germany, in 2006

In parallel to an ongoing time series in the subtidal of List Reede, 12 fixed sites were sampled in the adjoining intertidal area between September 2003 and June 2012. Analyses comprised abundances and species composition of macrozoobenthos (sieve size 1 mm) and granulometric sediment composition. This dataset contains the results from seven sampling dates in 2006.

Zoobenthos and sediments time series in southern Königshafen, Sylt, Germany, in 2010

In parallel to an ongoing time series in the subtidal of List Reede, 12 fixed sites were sampled in the adjoining intertidal area between September 2003 and June 2012. Analyses comprised abundances and species composition of macrozoobenthos (sieve size 1 mm) and granulometric sediment composition. This dataset contains the results from three sampling dates in 2010.

Zoobenthos and sediments time series in southern Königshafen, Sylt, Germany, in 2008

In parallel to an ongoing time series in the subtidal of List Reede, 12 fixed sites were sampled in the adjoining intertidal area between September 2003 and June 2012. Analyses comprised abundances and species composition of macrozoobenthos (sieve size 1 mm) and granulometric sediment composition. This dataset contains the results from five sampling dates in 2008.

Zoobenthos and sediments time series at List Reede, Sylt, Germany, in 2018

A shallow subtidal area in the northern Wadden Sea was monitored for sediment parameters and macrobenthic fauna using stratified random sampling of a grid of 33 sampling positions. Samples were collected with a Reineck-type box-corer of 0.02 m² surface area. Granulometric sediment composition was analysed from a sub-sample of each box-core using a diffraction laser particle-size analyser. Macrobenthos (sieved through 1 mm square meshes and fixed in buffered formalin solution) was counted, identified to species level, and the size of hard-shelled individuals measured. The amount of shell detritus was quantified as wet-weight in the benthos samples. This dataset contains the results from the sampling events in 2018.

Zoobenthos and sediments time series at List Reede, Sylt, Germany: pilot samples in 2001

In preparation for a forthcoming monitoring project, a shallow subtidal area in the northern Wadden Sea was studied for macrozoobenthos >1 mm sieve size. Using a Reineck-type box-corer of 0.02 m² surface area, abundance and specific composition were evaluated from a sampling grid of 21 positions with two replicates each. Temporarily, sampling was repeated 9 times. Analyses of spatial and temporal variability revealed that within-site variability was far lower than between-site variability. As a consequence, the later monitoring project was based on a higher number of study sites at the cost of within-site replication.

Zoobenthos and sediments time series in southern Königshafen, Sylt, Germany, in 2011

In parallel to an ongoing time series in the subtidal of List Reede, 12 fixed sites were sampled in the adjoining intertidal area between September 2003 and June 2012. Analyses comprised abundances and species composition of macrozoobenthos (sieve size 1 mm) and granulometric sediment composition. This dataset contains the results from four sampling dates in 2011.
