The dataset was acquired at the time-series station Boknis Eck (54.5°N and 10.0°E) at six standard depths (1, 5, 10, 15, 20, 25 m). The dataset contains data for ammonium (sampled with a rosette sampler and measured using a QuAAtro Continuous Segmented Flow Analyzer). The data are from 1979 to 2023.
The dataset was acquired at the time-series station Boknis Eck (54.5°N and 10.0°E) at six standard depths (1, 5, 10, 15, 20, 25 m). The dataset contains data for Chlorophyll a (sampled with a rosette sampler, measured using a fluorometer until 2019 and using high performance liquid chromatography from 2019). The data are from 2015 to 2021.
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.
Data from 1997-2018 were logged every 8 minutes in the Inner Kiel Fjord (54°19'46.0"N; 10°08'58.3"E) in shallow waters (Hydrometeorological station: Fa. Driesen und Kern, Bad Bramstedt). Until 2013 the sensor was deployed floating at the surface, but due to settlements on the floating device, the actual depth is not perfectly certain. Therefore, in 2013 the sensor was mounted to a fixed depth of 1.8 m (below sealevel). If a value differed more than 1.0°C from the preceding and following value, the value was interpolated between the two adjacent values. If values were 2) constant for more than 4 hours, 2) missing within ± 8 min, and if 3) changes in values exceeded 0.7°C within 16 min, the values were set to NA. This holds true for the following times: 1999-05-21 21:20 - 1999-06-17 15:00, 2000-11-10 12:00 - 2000-11-18 10:00, 2001-01-06 12:20 - 2001-01-08 07:40, 2014-08-30 18:00 - 2014-09-19 16:20, 2015-01-07 14:40 - 2015-02-23 20:00, 2016-11-09 03:20 - 2016-12-04 03:20 - 2017-01-24 23:25 - 2017-01-25 12:00. Gaps larger than 3 days were filled with data (if available) obtained from sensors very close to the actual measuring site (SeapHOx, Scripps Research Institute San Diego 1m; or Hydrometeorological station, Fa. Driesen und Kern, Bad Bramstedt 1.5m): 2000-11-11 - 2000-11-17 (Hydrometeorological station), 2001-08-03 - 2001-08-28 (Hydrometeorological station), 2005-10-07 - 2005-10-17 (Hydrometeorological station), 2006-02-09 - 2006-02-22 (Hydrometeorological station), 2014-08-29 - 2014-09-18 (Hydrometeorological station), 2015-01-08 - 2015-02-24 (Hydrometeorological station), 2016-03-10 - 2016-03-13 (SeapHOx), 2016-06-03 - 2016-06-15 (SeapHOx), 2016-11-10 - 2016-12-05 (SeapHOx). Data from 1.5 m water depth were corrected by subtracting a systematic deviance of 0.3°C.
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.
