One year seawater temperature recording inside a breakwater area in the Northern and Central Adriatic Sea.

Temperature is considered to be one of the main driving factors for faunal composition and seems to play an important role in several species, mostly evident in juveniles phases. In order to outline the thermal characteristics of an area protected by a breakwater system, the Mini-Log STAR ODDI® Data Storage Tag DST centi-TD temperature depth recorder was placed in the middle of that sea stretch. Sampling site was located at 43.6200014 latitude N, 13.426419 longitude E, at 30 cm depth. This instrument is capable of recording water temperature and pressure at 1-hour intervals. To prevent data loss due to theft/loss or depletion of the charge reserve, the instrument has been replaced at intervals and promptly replaced with an identical model. Water temperatures were recorded in the area for about one year, from 10 May 2013 to 3 April 2014, with a replacement of the DST centi-TD temperature depth recorder at 19 June 2013, 24 September 2013 and 4 December 2013. The selection of sampling site has been selected not only taking into account logistic needs but also based on the proximity with an open sea water monitoring station. In fact, the temperature data were also collected in a very close site at the 1.2 nautical miles offshore Senigallia harbor (43° 44.21'N, 13° 13.13'E) at the observation station TeleSenigallia pylon owned by the CNR-ISMAR of Ancona. This detection station is equipped with various types of multiparameter probes, including the Campbell Scientific ©, Inc. CS450 Submersible Pressure Temperature Transducer, fixed -2 m underwater and Campbell Scientific ©, Inc. CS109 Temperature Probe, fixed above sea level. All the data collected on this site have been automatically real time transmitted.
