This dataset consists of surface measurements of partial pressure of CO2 (pCO2), pH on total scale, water temperature, salinity, and other variables in the Casco Bay, Gulf of Maine from 2015-04-23 to 2020-06-12. The central goal of this project was to install continuous monitoring sensors in Casco Bay to measure ocean and coastal acidification parameters at high temporal resolution. The system was installed at the Southern Maine Community College (SMCC) pier in South Portland, Maine. The pier is located in the Portland Channel, an important southern outlet of Casco Bay, and near outlets of the Fore and Presumpscot rivers in a relatively urban area of Casco Bay. This location was selected because it is nearshore, accessible, and has historic nutrient data collected by the Friends of Casco Bay. Sensors for temperature/conductivity/salinity, dissolved oxygen, pH and pCO2 were mounted to a ‘lander’ frame, which was lowered via davit to the bottom. Sensor data were thus collected approximately 1m from the bottom, and at varying depth depending on the tide.

This dataset includes Surface underway, chemical and physical data collected from ARMORIQUE in the English Channel from 2012-04-25 to 2013-01-03. These data include DISSOLVED INORGANIC CARBON (DIC), Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and TOTAL ALKALINITY (TA). The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer. These data were collected by Yann Bozec of Centre National de la Recherche Scientifique (CNRS) and Pierre Marrec of Roscoff Biological Station as part of the Coastal_FerryBox_Roscoff_Plymouth_35AQ20120425 dataset. CDIAC associated the following cruise ID(s) with this dataset: 35AQ20120425

Measurements from the Pelican research vessel made off the southern coast of Louisiana in the Gulf of Mexico from 2006.

This dataset consists of hourly continuous measurements of pH, partial pressure of carbon dioxide (pCO2), salinity and temperature were collected at the University of Texas Marine Science Institute Research Pier, Aransas Ship Channel, TX, Gulf of Mexico from 2016-11-08 to 2017-08-23 using a SeaFET (pH), SAMI-CO2 (pCO2), and YSI (temperature and salinity) sensors. To reduce the maintenance cost and effort for sensors deployed in warm water that experiences intense biofouling, the sensors were set up to measure in situ seawater from an ex situ position. Water was pumped from approximately 1 m below the sea surface into the bottom spigot of a cooler that housed the sensors. To allow water outflow, a 1-inch hole was drilled at the opposite side of the spigot near the top of the cooler rim. The pump was programmed to turn on 20 minutes before each hour, pumping more than enough water to fully flush the cooler, and sensors recorded measurements on the hour. The YSI sonde was deployed directly into the Aransas Ship Channel inside a 2-inch PVC pipe at approximately 1 m below the sea surface. Funding for sensors and sensor deployment came from United States Environmental Protection Agency's National Estuary Program via the Coastal Bend Bays and Estuaries Program Contract No. 1605.
