The Astan-Roscoff time-series data characterize the temperature and salinity of the Western English Channel. Between 1952 and 1982 the sampling station was located to the north-west of Batz Island. Since 1983, the sampling station is located at the current (https://www.somlit.fr/)-[https://www.somlit.fr]), accredited by the CNRS as a national Earth Science Observatory (Service National d’Observation: SNO), aiming at assessing their long-term evolution including both natural and anthropogenic forcings. Samples were collected with a Niskin bottle at high tide slack during neap tides at 2m-depth and at 60m-depth for the 1983-1999 period. Until 1970 the exact date of sampling is unknown, hence in the data set, the 1st of the month is present. Water samples where analysed for Salinity with a Salinometer Guidline Autocal and Temperature was measured during sampling with a reversing mercury thermometer (Richet and Wiese). Starting in 2000, this time series has been integrated in the SOMLIT ASTAN time-series, which is part of the( SOMLIT National Observation Service)-[https://www.somlit.fr/].

This data set contains the CTD data collected by the Stazione Oceanografica of CNR (Italy) from RV URANIA during eight oceanographic campaigns (Table 1). These cruises were part of an intensive field program in the Sicily Channel and in the southern Tyrrhenian basin conducted within the MATER project, funded under FP4-MAS3 (Grant agreement ID: MAS3960051). Data have been used in several studies (see Related documents).

The probes were calibrated in temperature and conductivity at the SACLANT Center of La Spezia, before and after each cruise, and at sea in salinity, against water samples. Declared instrumental precisions were 0.002 °C for temperature and 0.005 for salinity (PSS-78). The data set is provided per cruise as ODV Spreadsheet files in TXT format, containing: Cruise name Station number Type of acquisition (here C for CTD) Date in mon/day/yr and Time in hh:mm:ss Coordinates in Longitude [degrees_east] and Latitude [degrees_north] Bottom depth [m] Depth, salt water [m] Temperature, IPTS-68 [degC] Temperature, ITS-90 [degC] Salinity, PSS-78 (Practical Salinity)   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

The Central Adriatic Sea is characterized by three depressions collectively known as Pomo (or Jabuka in Croatian) Pits, with a maximum depth of about 270 m ((Marini et al 2016)-[https://doi.org/10.1016/j.margeo.2015.08.015]). A spring survey, aimed at assessing the N. norvegicus population inhabiting the Pomo Pits (Central Adriatic Sea, Mediterranean basin) by means of a towed underwater camera (UWTV), is carried out since 2009 by the Ancona section of CNR-IRBIM (formerly part of CNR-Institute of Marine Science; Italy) on board R/V Dallaporta ((ICES 2014)-[https://www.ices.dk/sites/pub/Publication%20Reports/Expert%20Group%20Report/SSGESST/2014/WGNEPS14.pdf]). A calibrated SBE 19plus V2 probe (SeaBird Electronics,USA) was therefore embedded in the UWTV system in order to obtain CTD profiles all along the sledge operations: deployment at seas, sledge dragged on the seabed and hauling ((Martinelli et al. 2016)-[https://dx.doi.org/10.1016/j.oceaneng.2015.10.037]). The multi-parameter probe was also equipped with a SBE 43 dissolved oxygen (concentration and saturation) sensor. A SBE 5T pump ensures a constant flow over time inside the sensors. The dataset here presented contains also classic CTD casts carried out in the area in spring 2021. In total this spring dataset consists of 250 CTD and oxygen averaged profiles (0.5 db pressure interval) collected in springtime (from 2012 to 2021) within the Pomo Pits and in the surrounding area by means of multi parametric probes embedded on an UWTV system. All the profiles were subjected to quality control. Data are flagged according the (L20 (SEADATANET MEASURAND QUALIFIER FLAGS))-[http://seadatanet.maris2.nl/v_bodc_vocab_v2/search.asp?lib=L20].   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.

From 2003 to 2013, the Ancona section of CNR-IRBIM (formerly part of CNR-Institute of Marine Science) runned the “Fishery Observing System” (FOS) program aimed at using Italian fishing vessels as Vessels Of Opportunity (VOOs) for the collection of scientifically useful datasets ((Lucchetti et al. 2018)-[http://doi.org/10.1016/j.marpol.2018.09.031]). In 2012, thanks to the participation to some national and international projects (e.g. SSD-Pesca, EU-FP7 JERICO etc.), CNR started the development of a new modular “Fishery & Oceanography Observing System” (FOOS; (Patti et al. 2016)-[http://dx.doi.org/10.1080/1755876X.2015.1120961]). CNR-IRBIM implemented the “AdriFOOS” observational system, by installing the FOOS on some commercial fishing boats operating in the Adriatic Sea. Since then the datacenter based in Ancona receives daily data sets of environmental parameters collected along the water column and close to the sea bottom (eg. temperature, salinity, etc.), together with GPS haul tracks, catch amounts per haul, target species sizes and weather information. Some temperature and salinity measurements acquired by the FOOS in the Adriatic Sea from January 2014 to March 2015 were published within the (NEXOS project)-[http://nexos.demo.52north.org/demo-client/#/profiles/selection]. The dataset here presented contains 14810 depth (pressure)/temperature profiles collected by 10 vessels of the AdriFOOS fleet in the period 2012-2020. All the profiles were subjected to quality control.Data are flagged according the (L20 (SEADATANET MEASURAND QUALIFIER FLAGS))-[http://seadatanet.maris2.nl/v_bodc_vocab_v2/search.asp?lib=L20].

The Central Adriatic Sea is characterized by three depressions collectively known as Pomo (or Jabuka in Croatian) Pits, with a maximum depth of about 270 m ((Marini et al 2016)-[https://doi.org/10.1016/j.margeo.2015.08.015]). In addition to being characterized by a very peculiar bathymetry and oceanographic characteristics, this area hosts one of the main nursery for the European hake Merluccius merluccius within the Northern and Central Adriatic Sea ((GFCM 2021)-[https://www.fao.org/gfcm/statutory-meetings/detail/en/c/1457591/]).  In the framework of an agreement with the Italian Ministry of Agriculture and Forestry (MIPAAF), CNR-IRBIM carries out since 2015, on board R/V Dallaporta, an autumn trawl survey in the western side of the Pomo Pits area; the survey aims to evaluate the effects of the management measures enforced in the area on the most commercially and ecologically important species (ScamPo survey; Martinelli et al. 2021). Furthremore, to understand possible effects of environmental changes on the species abundance and distribution, before or after each trawl haul, CTD (Conductivity Temperature Depth) data are collected with a SeaBird Electronic SBE 911plus (years 2015-2019) and SeaBird Electronic SBE 19plusV2 (years 2020 and 2021). The multi-parameter probes are also equipped with a SBE43 dissolved oxygen (concentration and saturation) sensor. A SBE 5T pump ensures a constant flow over time inside the sensors. The dataset here presented contains 61 CTD and Oxygen averaged profiles (0.5 db pressure interval) collected in autumn (from 2015 to 2021) within the Pomo Pits and in the surrounding area by means of multi parametric probes.  All the profiles were subjected to quality control.
