This dataset includes surface underway, chemical, meteorological and physical data collected from M/S Trans Future 5 in the, North Pacific Ocean, Philippine Sea, Solomon Sea, South Pacific Ocean and Tasman Sea from 2023-01-07 to 2023-11-05. These data include absolute humidity, air temperature, air-sea difference - partial pressure of carbon dioxide (pCO2), pCO2 - atmosphere, pCO2 - water, barometric pressure, relative humidity, sea surface salinity, sea surface temperature, wind direction and speed.

Vertical temperature profiles were collected from January 7th 2020 to January 12th 2020 from the research vessel Laura Bassi during an oceanographic cruise between New Zealand and the Ross Sea in the framework of the Marine Observatory in the Ross Sea (MORSea) project of the Italian National Antarctic Research Programme (PNRA). Sippican T7 Expendable Bathythermograph (XBT) probes with a vertical resolution of 65 cm and a maximum nominal depth of 760 m were used. The mean spatial resolutions ranges between 15 nm and 20 nm, according to the specific part of the cruise.

This dataset consists of gridded monthly data products of surface ocean acidification indicators from 1998 to 2022 and on a 0.25° by 0.25° spatial grid have been developed for eleven U.S. Large Marine Ecosystems (LMEs) using a machine learning algorithm called random forest regression (RFR).

Vertical temperature profiles were collected from February 8th 2019 to February 12th 2019 from the research vessel Araon during an oceanographic cruise between New Zealand and the Ross Sea in the framework of the Marine Observatory in the Ross Sea (MORSea) project of the Italian National Antarctic Research Programme (PNRA). Sippican T7 Expendable Bathythermograph (XBT) probes with a vertical resolution of 65 cm and a maximum nominal depth of 760 m were used. The mean spatial resolutions ranges between 15 nm and 20 nm, according to the specific part of the cruise.

This dataset includes surface underway data collected from R/V Ryofu Maru III cruises in the Pacific Ocean, Japan Sea, East China Sea from 2023-01-25 to 2023-09-16. These data include partial pressure of carbon dioxide in the water, barometric pressure, sea surface salinity and sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.

This dataset includes surface underway data collected from R/V Keifu Maru II in the Pacific Ocean, East China Sea and Sea of Japan, from 2023-01-25 to 2023-09-28. These data include barometric pressure, partial pressure of carbon dioxide - atmosphere, partial pressure of carbon dioxide - water, sea surface salinity and sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.

This dataset includes the discrete profile measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, ammonia, water temperature, salinity, dissolved oxygen and nutrients during the R/V F. G. Walton Smith cruise WS23061 (EXPOCODE 33WA20230302) in the North Atlantic Ocean, Gulf of Mexico from 2023-03-02 to 2023-03-09. Near-shore estuarine and coastal regions are where most recreational fishing and tourism occur, yet they are vastly under-sampled. Their susceptibility to OA is not well understood due to their high biogeochemical variability.

This data package contains 10 global subsurface ocean acidification (OA) indicators at standardized depth levels of 50, 100, and 200 meters. The indicators include fugacity of carbon dioxide, pH on the total scale, total hydrogen ion content, free hydrogen ion content, carbonate ion content, aragonite saturation state, calcite saturation state, Revelle Factor, total dissolved inorganic carbon content, and total alkalinity content.

This NCEI Accession consists of surface underway measurements collected from the M/V Seaspan Royal as it transited the coastal waters of British Columbia, Canada from 2023-01-04 to 2023-11-21. Seawater was drawn from a depth of 2.5 m to a Sunburst SuperCO2 system and ancillary sensors from Sea-Bird Scientific. Measurements of temperature, salinity, dissolved oxygen content, and CO2 partial pressure were made every 2 seconds on seawater flowing through the system and instruments, and these data were logged by the SuperCO2 system.

This dataset consists of surface underway measurements collected during the R/V Algoa cruise Southern Benguela (IEP:SB) (EXPOCODE 91AL20211115) in the coastal waters of South Africa from 2021-11-15 to 2021-11-23. The sea-surface partial pressure of CO2 (pCO2) was measured in the Southern Benguela off the west coast of South Africa as part of the November 2021 Integrated Ecosystem Programme: Southern Benguela (IEP:SB). The IEP is a multi-disciplinary, multi-institutional platform to undertake research and monitoring in the Southern Benguela.
