The Universidad del Caribe responds to the demand for technical support for the elaboration of specific bathymetric charts for a polygon of 458 Ha that is located between the Isla Contoy National Park and Cayo Alcatraz. The objective was to make a bathymetric map of the polygon and point out the main characteristics or morphological features. Likewise, CTD cast were carried out to have a database with future application to mariculture, with the purpose of contributing to the economic development of communities in Quintana Roo through economic diversification and regional cultural identity and promoting fair trade and solidarity that favor the production and consumption of original products.This activities of the Node for the Promotion of the Social and Solidarity Economy (NODESS) called Selva, Mar y Comunidad Pre Registration Folio SINCA_PNSS_20_00009_INAES, made up of the Universidad del Caribe, Directorate of Economic Promotion of the H.

The Slocum G2 Glider MIA was deployed in the Gulf of Finland, Baltic Sea, in May-June 2018. The glider sampled an 18 km long section (S–N direction). This data set is the processed delayed time CTD data from that mission. Processing included applying standard quality control and considering response times and thermal lag. The data were binned, and half YOS were arranged as profiles, meaning the variables in the data set are presented as 2D fields.

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.

This dataset contains the controled temperature data in °C from the two temperature sensor (Bottom and Top) inside the CISICS colonizer deployed between September 2016 and February 2017 (n=24924) inside the Aisics Chimney. (data acquired every 15 min.)

The principal aim of the Tyrrhenian Eddy Multi-Platform Observations (TEMPO) experiment  (1989-1993) was to study the signature of a mesoscale oceanographic eddy in the north Tyrrhenian Sea, between Italy, Corsica and Sardinia, using space-borne and airborne remote sensing and ship-based measuring techniques, but an effort was made to extend the observations in the southern part of the Tyrrhenian sea and throughout the water column.  The data contained in this dataset concerns the cruises TEMPO-3 (from 25 October to 8 November 1991, 44 stations), TEMPO-4 (from 23 April to 4 May 1992, 41 stations), and TEMPO-5 (from 8 to 13 March 1993, 71 stations). CTD profiles were collected using a Neil-Brown MK III CTD probe with a sampling time of 33 ms and a CTD fall speed of about 1 m/s. The temperature, conductivity and pressure sensors were calibrated at the SACLANT Centre in La Spezia before the cruise and again checked after its conclusion. Water samples were collected for the on-board calibration of the probe values. The final accuracies for the temperature and salinity were0.005 °C and 0.005, respectively. Successively the data were interpolated over 1 dbar interval. The data set is provided per cruise as ODV Spreadsheet files in TXT format, containing: Cruise name Station number Type of acquisition (here C) Date in mon/day/yr and Time in hh:mm:ss Coordinates in Longitude [degrees_east] and Latitude [degrees_north] Bottom depth [m] Depth [m] Temperature_IPTS-68 [deg C] Conductivity [S/m] Temperature_ITS-90 [deg C] Salinity_PSS-78 (Practical Salinity) Dissolved Oxygen [ml/l]   Important Note: This submission has been initially submitted to SEA scieNtific Open data Edition (SEANOE) publication service and received the recorded DOI.
