This dataset contains turbidity (NTU) data acquired between April 2015 and September 2016 using a Wetlabs turbidimeter (ECO-BBRTD, serial # 215R) installed horizontally at 1.5 m height at the top of the SeaMoN East frame. The sensor was not calibrated as the sizes of the natural particles are unknown. Data was acquired every 15 minutes. The instrument is part of the SeaMoN East ecological monitoring node. Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI. The metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

This dataset contains dissolved iron concentrations ((Fe(II) + Fe(III); µmol/l) acquired between July 2017 and March 2018 (n=168) using the CHEMINI Fe, a CHEmical MINIaturized analyser (samples taken every 12 hours, with daily in situ calibration using a 20 µmol/l iron standard, Vuillemin et al., 2009). The sample inlet was positioned on the mussel bed at the base of the Tour Eiffel edifice of the Lucky Strike hydrothermal vent (1695 depth).CHEMINI Fe (CF2) was mounted on the TEMPO module which was itself connected to the SeaMON East node of the EMSO-Azores observatory.

This dataset contains real-time total dissolved iron concentrations ((Fe(II) + Fe(III); µmol/l) acquired from the EMSO-Azores seafloor observatory from September 2013 to February 2014 (n=332). Data are purchased by the CHEMINI Fe (CF1), a CHEmical MINIaturized analyser dedicated to in situ determination of iron concentrations (every 24 hours, with in situ calibration using a 25 µmol/l iron standard, Vuillemin et al., 2009). The instrument is deployed on TEMPO part of Seamon East environmental monitoring node. The sample inlet is located on a mussel bed at the base of the Eiffel Edifice at 1695m depth.

This dataset contains temperature (°C) and dissolved oxygen concentrations (µmol/l) acquired between April 2015 and September 2016 using an Aanderaa optode (model 3830, sensor head # 1180-520, salinity setting 3.5%, uncorrected for pressure) The sensor. The sensor was positioned on a mussel bed at the base of the Tour Eiffel edifice (1695m depth). Data was acquired every 15 minutes. A two-point calibration at 0% and 100% saturation levels is performed at each maintenance cruise. The optode connected to the TEMPO ecological module is part of the SeaMoN East monitoring node.
