A mooring, equipped with a CTD sensor (SBE37) at 350 m depth, was deployed in the Yermak Pass on the 24 September 2017 from the R/V Lance. The mooring was recovered in summer 2020 from K/V Svalbard. The present dataset provides 10-day smoothed time series of daily conservative temperature (CT, °C), absolute salinity (SA, g/kg) and pressure (db) recorded by the SBE37 sensor, from the 24 September 2017 to the 31 May 2020. The mooring was located at 80.63°N, 6.88°E.

Memorial University has over the past 15 years been involved in various ocean glider activities with deployments focused primarily on the Newfoundland Shelf and the Labrador Sea. For example, there are four deployments with glider data in the Labrador Sea. Partnerships with Fisheries and Oceans Canada and Ocean Gliders Canada have also resulted in deployments of Memorial's gliders in the Pacific. The data contain 14’663 mission kms, 620 deployment days and 25’108 individual glider profiles. L1 NETCDF files for every deployment archived on the Memorial University’s Glider Data server are made available publicly for scientific research. Deployments vary in duration and region. All files were processed with the SOCIB glider toolbox ((Troupin et al., 2015)-[https://doi.org/10.1016/j.mio.2016.01.001]), modified by Nicolai von Oppeln-Bronikowski, 2019 for MUN glider deployments. Metadata: File creator(s), contact info, institution, applicable funding, responsible researcher(s), deployment region, deployment start, deployment end, longitude min, longitude max, latitude min, latitude max, glider type, glider configuration if known, sensors, sensor serial numbers, science data QC. Glider Data: Minimum Data: Time, Depth, Position, Depth-Averaged Current, CTD.

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.

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.

The datasets contains selected data from the underwater glider missions in Eastern Mediterranean performed in April-May and in August 2023 by Institute of Marine Sciences, Middle East Technical University (METU-IMS). The glider was donated to METU-IMS by Is Bankasi - the national commercial bank in Turkey. The underwater glider SeaExplorer X2 of ALSEAMAR is equipped with the following instruments: 1) RBRlegato³ C.T.D (non-pumped flow) with temperature, conductivity and pressure sensors; 2) JFE Advantech Co. Rinko Fast Optical DO sensor; 3) Wet Labs ECO Puck (fluorescence and turbidity); 4) Sea-Bird Scientific Deep SUNA Ocean Nitrate Sensor; 5) Altimeter. The research area is between mainland and Cyprus bounded by a rectangle with coordinates 35.52°-36.1°N, 33.2°-33.5°E. The first mission with internal number 16 was carried out in period April, 26 – May, 16, 2023, the second mission with internal number 20 was carried out in period August, 2 – August, 27, 2023. The first and last transects from each mission are included in the dataset. The dataset is submitted as zip-archive containing 110 .gz files. Each .gz file contains instrument output acquired within one glider dive cycle.

Repeat hydrography, as organized through the GO-SHIP network, is fundamental for detecting trends and variability also in the Mediterranean Sea. The Mediterranean component of GO-SHIP is MedSHIP, and TAlPro is the western Mediterranean component. The TAlPro2022 cruise consisted of 26 full depth hydrographic stations crossing the Tyrrhenian Sea from north to south, then the Algero-Provencal Basin from south to north. Here the postcalibrated bottle file data are made availiable. Postcalibration has been done by measuring dissolved oxygen and salinity on water samples collected by the rosette. The dataset contains also all chemical variables, measured in the lab.

Apataki Atoll has been instrumented over a period of 3 months (from April 2022 to late July 2022) separated into 2 Legs. Physical process such as water level, currents ciruclation, water exchanges into passes and "hoa" and water column stratification have been measured to characterized the hydrodynamic functioning of this semi-opened pearl farming atoll. Numerous moorings have been deployed into lagoon, passes, hoa and external reef slope stations with common autonomous oceanographic instruments measuring at high sampling frequency. During the sampling period, one major meteorological event occurred, a distant mega swell hit the South-West Islands of French Polynesia including Apataki on 14th July and has significantly impacted its hydrodynamic.

Conductivity-Temperature-Depth (CTD) data and Lowered-Acoustic-Doppler-Current-Profiler (LADCP) data from the 22 casts of the MomarSat 2022 Cruise. The CTD data from a Seabird SBE 25 were processed with Seasave V 7.26.7.121 software. Note that the conductivity/salinity data were NOT calibrated with bottles. Only basic CTD processing was done. The LADCP horizontal currents were measured with a combination of two 300 kHz RDI ADCPs, one uplooker and one downlooker. LADCP data were processed with the LDEO v. IX.12 software with a 10-m vertical resolution.
