This dataset contains real-time total dissolved iron concentrations ((Fe(II) + Fe(III); µmol/l) acquired from the EMSO-Azores seafloor observatory TEMPO from July 2011 to March 2012 (n=1780). Data are purchased by the CHEMINI Fe (CF0), a CHEmical MINIaturized analyser dedicated to in situ determination of iron concentrations (every 12 hours, without in situ calibration, 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. 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 the meteorological parameters (mean wind speed, temperature in °C and atmospheric pressure in mbar) acquired between Jannuary 2012 and December 2012 (n=332) using the Furuno Rowind+, mounted at the top of BOREL superstructure (data acquired every 6 hours).

This dataset contains temperature data acquired between July 2012 and August 2013 using 17 temperature probes (HTW, HTNKE and LTW) installed in smoker orifices or cracks. High-temperature WHOI probes (HTW) are composed of 2 J-type thermistors in the rod tip connected to 2 temperature data-loggers (named A & B), 2 data recordings are available for 1 HTW probe. They are able to record temperatures up to 415°C with an accuracy of ± 1.1°C, a resolution of 0.25°C at 375°C and a clock drift of 1min per month. High-temperature NKE probes (HTNKE) are able to record temperatures up to 450°C, with an accuracy of ±0.5°C, a resolution of 0.1°C and a clock drift of 1min/month. Low-temperature WHOI probes (LTW) are able to record temperatures up to 125°C. with an accuracy of ±0.22°C, a resolution of 0.025°C and a clock drift of ±1min per month. The array is not connected to an energy node. All probes are calibrated in time before deployment, probe time adjusted to UTC time. Temperature of probes is checked after recovery and before deployment. Clock drift after recovery is not implemented in data.
