This data package contains Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown 2021 West Coast Ocean Acidification cruise RBWCOA2021 (EXPOCODE 33RO20210613) in the North Pacific Ocean from 2021-06-14 to 2021-07-20. Data were collected from the ship's underway seawater supply during the NOAA Ocean Acidification Program-funded West Coast Ocean Acidification (WCOA) cruise. This underway TA effort was part of the NOAA Ocean Acidification Program (OAP) grant entitled "Expanding near-shore carbonate measurements along the East-coast and Gulf of Mexico through multiple collaborations". Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML.

This dataset includes profile discrete measurements of temperature, salinity, oxygen, nutrients, chlorofluorocarbons (CFC-11, CFC-12), dissolved inorganic carbon (DIC), total alkalinity, pH on sea-water-scale, dissolved organic carbon (DOC, TDN), and other measurements obtained during NOAA Ship Ronald H. Brown cruise along the GO-SHIP Repeat Hydrography Section P18 (EXPOCODE 33RO20161119) in the Pacific Ocean from 2016-11-19 to 2017-02-03. This data are from the 2016/2017 occupation of the P18 hydrographic section aboard NOAA Ship Ronald H. Brown acting under the auspices of the Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP).

This data package contains Underway total alkalinity, water temperature, salinity and other variables collected from surface seawater during the NOAA Ship Ronald H. Brown 2022 East Coast Ocean Acidification cruises (ECOA2022) (EXPOCODEs 33RO20220806, 33RO20220906) in the North Atlantic Ocean, U.S. East Coast from 2022-08-06 to 2022-09-23. Data were collected from the ship's underway seawater supply. This effort was part of the NOAA Ocean Acidification Program (OAP) grant. Along with total alkalinity, corresponding temperature and salinity measurements are included. Measurements of pCO2 taken on these cruises are available from NOAA's AOML.

JASMINE is the first comprehensive study of the coupled ocean-atmosphere system in the eastern Indian Ocean and the southern Bay of Bengal. Observations made during the field phase of JASMINE sampled both prolonged break and active phases of the monsoon resulting in an unprecedented amount of research quality data defining the atmospheric and oceanic state during intra-seasonal transitions of the monsoon. The design of the JASMINE pilot study was based on the observation that the intra-seasonal variability of the monsoon, as it sways back and forth from active to inactive (or break) phases, is an important component of the monsoon system and one that is poorly sampled and simulated.
