  • Students and researchers at the University of the Caribbean together with members of the Cooperative Sea of ??the Antilles, conducted an oceanographic campaign at the site called cayo Alcatraz, where there are two underwater springs also known as “ojos de agua”. These springs are located within the polygon of the protected area of ??the Mexican Caribbean Biosphere Reserve, to the west of Isla Contoy National Park. The purpose of the campaign was to begin studies of the environmental conditions and reconnaissance of the site. The measuring instruments used were; SonTek CastAway-CTD, and a Gopro Black 7 camera.  were made a set of 12 temperature, salinity, and conductivity profiles. Water samples were also taken for subsequent microbiological analysis.

  • As part of the ongoing PHANTOM (Poleward Heat Transport across the ACC) program of LOCEAN/Sorbonne University, we have recently occupied two full-depth Conductivity-Temperature-Depth (CTD) sections in the Udintsev Fracture Zone region during a current-meter mooring deploying cruise in February 2016 and a mooring recovery cruise in December 2017 on board the Korean icebreaker Araon, in collaboration with physical teams of Korea Polar Research Institute (KOPRI) and Korea Institute of Ocean Science and Technology (KIOST). Several hydrographic sections have been made in the upstream and downstream areas of the UFZ especially during the 1990s World Ocean Circulation Experiment (WOCE) period, such as WOCE P16 at 150°W and WOCE P17 at 135°W. However, no high-quality top-to-bottom hydrography has ever been performed in the UFZ itself at 144°W, despite its narrowest circumpolar choke point. Ref: Park et al. (2019), Observations of the Antarctic Circumpolar Current over the Udintsev Fracture Zone, the narrowest choke point in the Southern Ocean, JGR, in review.

  • This dataset was produced during the iMAR cruise “The Integrated assessment of the distribution of Vulnerable Marine Ecosystem along the Mid-Atlantic Ridge (MAR) in the Azores region”, that took place aboard the Research Vessel Pelagia of the Royal Netherlands Institute for Sea Research between May 18th  and June 2nd 2021. The iMAR cruise aimed to evaluate the role of the MAR in shaping latitudinal and trans-Atlantic patterns in deep-sea biogeography, connectivity and assemblages of deep-sea megafauna. This expedition was funded by the SEA OCEANS program of Eurofleets+ and the H2020 European project iAtlantic, and was led by the University of the Azores (Portugal) in collaboration with the Hydrographic Institute and University of Porto (Portugal), the University of Aarhus (Denmark), the National Oceanography Center (United Kingdom), GEOMAR (Germany), the University Museum of Bergen (Norway), the PP Shirshov Institute of Oceanology (Russia), and the University of Vale do Itajaí (Brazil). Nutrient analysis was performed according to Grasshoff et al, adopted for a 5 channel continues flow analyzer (Skalar San Plus, Skalar Analytical B. V., Breda, The Netherlands). Nitrite and nitrate+nitrite was measured using an ammonia buffer and sulfanilamide/alpha-Naphthylethylene diamine dihydrochloride colour reagent in phosphoric acid, with reduction of nitrate to nitrite by cadmium column of at least 80% measured reduction capacity (90-100% achieved), followed by quantification with spectrophotometric determination of the nitrite-azo dye at 540 nm. Nitrate was determined as the difference between nitrate+nitrite and nitrite measurements. Ammonia was measured using a citrate/tartrate buffer and phenol color reagent, catalyzed by hypochlorite and nitroprusside , followed by quantification with spectrophotometric determination of the phenol-ammonia complex at 630 nm. Phosphate samples reacted with antimo nytartrate and ammonium molybdate solution in sulfuric acidified solution, the resulting complex wasreduced by ascorbic acid to a deep blue dye, followed by quantification with spectrophotometric determination of the reduced antimony-phospho-molybdate complex at 880 nm. Silicate samples was acidified with sulfuric acid and reacted with ammonium molybdate solution, reduced by ascorbic acid to a blue dye with oxalic acid to remove phosphate interference , followed by quantification with spectrophotometric determination of the reduced molybdo-silicate complex at 810 nm. Methods used are accredited with expected detection limit of 0,04 µM for nitrite, 0,1 µM for nitrate, 0,3 µM for ammonia, 0,06 µM for Phosphate and 0,2 µM for silicate, with expected RSD between 4 and 7%for the individual nutrients. Certified reference materials (VKI type QC RW1 for ammonia, phosphate and nitrate) and internal reference materials for Nitrite and silicate was spiked at two levels to natural low nutrient seawater sample for quality assurance, recovering 91-109% of the spike for nitrite, nitrate, phosphate and silicate at with RSD% of 1 to 5%, and recovery of 84-91% for ammonia, with RSDs up to 15%. No corrections was performed on data the recoveries. Except for ammonia, all results was within the acceptance limits for accredited analysis. Analysis was performed over two runs, one with triplicates and then a fourth spare sample was included to investigate the ammonia instability, but it could not be determined if this was due to storage/transport or instrument The “.CSV” files of fully processed data contain data collected mainly in the North portion of the MAR in the Exclusive Economic Zone around the Azores.

The “.CNV” files of fully processed data contain data of twenty-two parameters interpolated at 1-meter bins, (Table 2), mainly in the North portion of the MAR in the Exclusive Economic Zone around the Azores.

  • Underwater imagery of Posidonia Oceanica area in Cala Santa Maria, Cabrera, Balearic Islands

  • Gardline Geosurvey Limited was contracted by Forewind Limited to survey the Dogger Bank Wind Farm Area between 04-Apr-2013 and 02-Aug-2013; work was undertaken on the inter project cable route corridors, the Tranche C zonal survey and the Met Mast West. The aim of the surveys was to carry out a geophysical investigation that would broadly assess the entire developable area of the zone and route. Seabed information was required in order to inform the site selection process and enable preliminary foundation design to be undertaken. The geological data acquisition programme was carried out on M.V. Sea Surveyor, which sailed from Hull and returned to Blyth upon completion of survey operations and M.V. Vigilant which sailed from Great Yarmouth and to where they returned upon completion of survey operations. This dataset is MBES (MultiBeamEchoSounder) data obtained using a Simrad EM710. Processed using Caris HIPS and SIPS 7.1 to produce a digital terrain model (dtm) of the bathymetric surface. Available in the following format: 1) xyz - space delimited text file of gridded bathymetry. Data stored as: Column One: Easting Column Two: Northing Column Three: Water Depth 2) Ungridded Soundings - space delimited text file of the 'point cloud' of MBES soundings. Data stored as: Column One: Easting Column Two: Northing Column Three: Water Depth 3) Arc ASCII grid - raster text file of gridded bathymetry.
