The mooring was deployed on 15 September 2017 from Norwegian Research Vessel Lance at 80.6°N and 7.26°E (depth of 730 m) in the Yermak Pass over the Yermak Plateau north of Svalbard. It comprised 3 instruments: an upward-looking RDI 75kHz, a Long Ranger Acoustic Doppler Current Profiler (ADCP) at 340 m with 16 m vertical resolution (25 bins of 16 m each) and a 2-hour sampling time; a Seabird SBE37 measuring temperature, salinity and pressure at 348 m with 10-minute sampling time; and an Aquadopp current meter at 645 m with a 2-hour sampling time. The mooring was retrieved on the 19 July 2020 by Norwegian Icebreaker K.V. Svalbard. The present dataset features: The ADCP 50-hour high pass filtered velocities and  the Aquadopp 50-hour high pass filtered velocities.

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]). 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.

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.

This dataset includes data of plastic litter collected by citizens and students during 12 campaigns that were organised in Crete (Greece) during the period May 2022 – May 2023. The campaigns were organized within the framework of the NAUTILOS Horizon 2020 project. More specifically the number of plastic litter items per category (using the J code List of the EMODnet Chemistry Thematic Lot n°4) was recorded together with information about the location, date, surface area covered, data contributor and some environmental characteristics (sediment, weather, surroundings).
