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 metadata elements have been further processed (refined) in EMODnet Ingestion Service in order to conform with the Data Submission Service specifications.

iodysséus ((https://www.iodysseus.org)-[https://www.iodysseus.org/]) is an offshore sailing ship equiped as an oceanographic platform. Data have been collected  during 3 legs (around 3500 nautical miles in total) during the spring 2019. The navigation zones are on biological phenomena, corresponding to the zones where the CO2 varies widely, thus measurements taken provide extra information to help restrict seasonal variability and the seasonal CO2 cycle (and help to calculate the rate of ocean acidification). (During the spring, the partial pressure of CO2 decreases during bloom phenomenon because planktonic microorganisms pump CO2 for their growth). The physico-chemical parameters of the surface water have been continuously measured thanks to an Ocean Pack : temperature, salinity, dissolved oxygen, chlorophyll-a concentration, and partial CO2 pressure (pCO2). (This device was developed and adapted for racing yachts. Both compact and light, it consumes very little energy. One of its many advantages is that it can still operate at speeds above 15 knots. It shows that modern oceanography is evolving towards more flexible models). leg 1: from 19-04-21 to 19-04-24 leg 2: from 19-05-13 to 19-05-21 leg 3: from 30-05 to mid june Three maps below: partiel pressure of CO2 (ppm) Image Reference: https://www.seanoe.org/data/00612/72407/illustrations/illustration-80.gif.

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.

This dataset contains monitoring data along the swedish coast for chlorophyll concentrations in the surface water. Usually a hose is lowered from the surface down to 10 or 20m and then enclosed, the water is then mixed and analysed for chlorophyll-a concentration.

The objective of COCOA is to identify mayor partways of nutrients and organic material in various coastal ecosystems around the Baltic Sea. Nutrients and organic matter are transformed and retained along the land-sea continuum, and COCOA will quantify how physical and chemical conditions as well as the boilogical components.
