  • In April 2017, two Ice Atmosphere Arctic Ocean Observing System platforms (IAOOS 23 and IAOOS 24) were deployed near the North Pole. Over the next 8 months, they meandered southwards with the ice in the Transpolar Drift, collecting measurements in the upper 250 m of Amundsen Basin, Nansen Basin and Fram Strait. The ocean profilers are PROVOR SPI (from French manufacturer NKE), which includes a Seabird SBE41 CTD (Conductivity, Temperature, Depth) and a dissolved oxygen (DO) Aandera 4330 optode. IAOOS 23 also featured a bio-optics sensor suite and a submersible ultraviolet nitrate analyzer (SUNA, Satlantic-Seabird Inc.). The bio-optics sensor suite (called Pack Rem A) combines a three-optical-sensor instrument (ECO Triplet, WET Labs Inc.) and a multispectral radiometer (OCR-504, Satlantic Inc.). The present dataset is composed of chlorophyll-a fluorescence, backscatter, irradiances (at 412, 490 and 555 nm), photosynthetically active radiation (PAR), nitrate and colored-dissolved organic matter data from the IAOOS 23 platform, as well as composites of absolute salinity, conservative temperature and apparent oxygen utilization data from both profilers. The profilers were set to perform two upward profiles a day from 250 m starting at approximately 6 am and 6 pm. In this dataset, chlorophyll-a, PAR and irradiances were corrected with a shift to set dark values to zero. Nitrate was interpolated vertically every 5 m, and all other parameters were interpolated vertically every 0.5 m.

    The dataset on freshwater aquaculture in the European countries was created in 2017 by AND-International for the European Marine Observation and Data Network (EMODnet). The dataset provides information about the location of freshwater finfish farms in the EU and partner countries where data are available. It is available for viewing and download on EMODnet web portal (Human Activities, https://emodnet.ec.europa.eu/en/human-activities). For EU MSs, it relies mainly on data collected under the Regulation (EU) 2016/429 (the ‘Animal Health Law’). As far as partner countries are concerned, data have been collected in Norway and in the UK (Scotland only), where detailed data are provided online. Data provided here cover Austria, Belgium, Bulgaria, Czechia, Denmark, Estonia, France, Greece, Ireland, Lithuania, Norway, Poland, Slovenia, Spain, and the UK (Scotland only). Each point has the following attributes (where available): status (Active, Expired, Inactive, Renewal), country, owner name, farm type (Carp, Diversified pond fish, Eel, Other diversified, Other specialised, Salmonids, Sturgeon, Trout), production method (Closed systems - recirculation, Ponds, Tanks/Raceways, Cages/Enclosures/Pens, Quarantine facility, Research facility, Other), production stage (Grow out for human consumption, Hatchery, Nursery, Brood stock, Put and take fisheries, Restoration of wild stock, Processing facility, Other), purpose (Commercial, Restocking, Other), Species from Source (English translation of the information provided on species grown in the source), point information (Polygon centroid, Original) depending on how the information is provided in the source (polygons or points), site_id and source_id (id from the source where available). The farm type relies on a typology established by AND-International, based on available information on species grown. A relational table provides harmonised information about species grown using Eurostat nomenclature for the Species Group (Carps, barbels and other cyprinids; Miscellaneous freshwater fishes; River eels; Salmons, trouts, smelts; Sturgeons, paddlefishes; Tilapias and other cichlids), the species name (commercial and scientific) and the code. Data have been updated for Austria, Czechia, Denmark, Estonia, Ireland, Lithuania, Norway, Poland, Slovenia, and the United Kingdom. Data from Spain have been added.

  • Here we provide data from the Ross Ice Shelf ocean cavity.  Location  -  The HWD2 Camp was established in October of 2017 at 80o 39.497’S, 174o 27.678’E where the ice is moving seaward at around ~600 m a-1 and is sourced from the Transantarctic Mountains.  Profiling Instruments -  Profiling was primarily conducted with an RBR Concerto CTD (conductivity-temperature depth) profiling instrument, and this was cross-calibrated against irregular profiles with an RBR Duet (pressure and temperature only), a SBE37 MicroCat CTD as well as moored SBE37 MicroCat CTDs.  The RBR unit is small and has suitable sensor capability (temperature and conductivity accuracies of ±0.002°C and ±0.003 mS cm-1).  Its conductivity cell design is not prone to fouling by ice crystals, making it ideal for work in the sometimes crystal-laden borehole conditions.   We were inconsistent in how we mounted the CTD on its protective frame and this appeared to make small difference in the conductivity signal (resulting in an ~0.03 psu variation).  This was post-corrected based on the essentially invariant mooring data from the lower water column as well as SBE37 cross-calibration profile data. Because of the potential for sediment contamination of the sensors, the profiles were mostly conservative in their proximity to the sea floor. On several occasions, profiles were conducted all the way to the sea floor. The temperature and salinity are presented in EOS-80 in order to compare with available data.  Eighty three profiles are provided here (ctd_HWD2_*.dat). In addition, limited microstructure profiling was conducted to provide insight into some of the mixing details. The profiles were conducted by lowering the instrument to the ice base then commencing a sequence of three up-down “yo-yos” before returning to the surface and downloading. A data segment is included here (VMP_HWD2.dat). There were some challenges registering the vertical coordinate for the profiles.  The melting of the borehole generates a trapped pool of relatively fresh water.  The interface between this and the ocean should be near the base of the hole or a little higher – with seawater intrusion.  However, there were some instances where the interface was at a higher pressure (i.e. apparently in the open water column). The best explanation for this is that the water in the borehole is not at static equilibrium for some period after initial melting. We use 34.3 psu as a cut-off, in addition to a pressure criterion to identify the top of the useful oceanic profile.  It is also not inconceivable that water was being ejected from the hole, but it is unlikely that this would have impacted in the consistent observed pattern.  Instrumented Mooring - The mooring instruments at HWD2-A comprised 5 Nortek Aquadopp single point current meters in titanium housings reporting to the surface (30-minute interval, Table SI-Three) via an inductive modem to a Sound-9 data logger and Iridium transmitter. The current meter measurements were corrected to account for the 138o magnetic declination offset (i.e. the south magnetic pole is to the north-west of the field site).  Five files are provided here (HWD2_Init_rcm*.dat4).  Details in: Stevens C, Hulbe C, Brewer M, Stewart C, Robinson N, Ohneiser C and Jendersie J, 2020.

  • Physical data associated with the ABRACO2 cruise. The ABRACOS2 cruise's main objective was to draw up a 3D characterisation of the abiotic and biotic compartments and their interactions. The cruise had 3 specific objectives: 1) Characterisation of water masses and their dynamics. Data collected (ADCP, CTD, rosette, etc.) will be used to study the physical connections between (i) ocean islands and coastal ecosystems and (ii) tropical/subtropical coastal regions to the South and equatorial coastal regions to the North. In-situ measurements will also make it possible to validate the regional high-resolution hydrodynamic models. 2) Ecosystem acoustics. Collecting multifrequency acoustic data in order to create the first 3D characterisation of island and coastal ecosystems in the Northeast Region of Brazil. Acoustic observations will be combined with sampling with pelagic trawl (Legs 1 and 2), bottom trawl (Leg 1), and with sampling of zooplankton and video images. 3) Biodiversity and food web structure. In-situ sampling will provide information about the distribution, biodiversity, trophic ecology (use of stable isotopes) and the contamination (methylmercury) of organisms. The related projects are ABRAÇOS and 'Planning in a liquid world: Marine spatial planning and network dynamics' (PADDLE), (H2020 RISE), (PI: M. Bonnin, 2017-2020).
