Continuous wave and tide observations at BEFmate artificial islands in the back-barrier tidal flat, Spiekeroog, Germany, 2014-10 to 2017-04

Data presented here were collected between October 2014 to April 2017 within the BEFmate project (Biodiversity - Ecosystem Functioning across marine and terrestrial ecosystems; https://www.icbm.de/verbundprojekte/befmate/ ) of the Universities of Oldenburg and Göttingen and the Nationalparkverwaltung Niedersächsisches Wattenmeer. Experimental islands and saltmarsh control plots were created in the back barrier tidal flat and in the saltmarsh zone of Spiekeroog island. Data were measured with a local installed wave logger next to the experimental islands in a tidal creek (0.71 m NHN). The wave logger used here is a RBRduo T.D / wave (RBR Ltd., Ontario/Canada). The sensor were pre-calibrated by the manufacturer. Sampling rate was 3Hz with 1024 samples per burst at a sample interval of 10 minutes. Recorded data were internal logged till readout with the Ruskin (V1.13.10) software and processed using MATLAB (R2012b). Data were visually checked and outliers removed. For depth calculations pressure data were manually corrected by atmospheric pressure. Low tide data is not removed. The position was derived from a portable DGPS-system. Date and Time is given in UTC.
