Continuous temperature observations in surface sediment within BEFmate artificial islands and saltmarsh control plots at different elevation levels, Spiekeroog, Germany, 2014-09 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 local installed temperature logger within the experimental islands as well as in the saltmarsh control plots at different elevation levels. Temperature logger used here are DEFI-T Miniature Temperature Recorder (JFE Advantech Co., Ltd., Tokyo). The temperature recorders were pre-calibrated by the manufacturer. Recorded data were internal logged till readout with the DEFI Series software (V1.02) and processed using MATLAB (R2012b). Data were visually checked and outliers removed.The position was derived from a portable DGPS-system. Date and Time is given in UTC.
