The dataset contains the selected physical properties and chemical constituents that were measured at Caño Boquerón, Cabo Rojo, and Puerto Mosquito, Isla de Vieques, Puerto Rico during a diurnal cycle. Two diel studies were conducted per lagoon to determine the community primary productivity. Photosynthesis creates oxygen which enhances microbiological activity and results in the production of organic matter. Primary productivity is important for supporting the food web in aquatic ecosystems. The field data collection included the measurement of temperature, dissolved oxygen, and percent of oxygen saturation. Measurements were obtained at about 1 hour intervals. Diel studies were conducted on October 29, 2015 and March 2, 2016 at Caño Boquerón, Cabo Rojo, Puerto Rico, and on November 17, 2015 and March 9, 2016 at Puerto Mosquito, Isla de Vieques, Puerto Rico.

This dataset contains the selected physical properties and chemical constituents that were measured at Puerto Mosquito, Isla de Vieques on June 22, 2017. A cross-sectional profile was conducted by measuring a total of ten selected site throughout the lagoon during the morning. Field water-quality measurements included the parameters of specific conductance, and dissolved oxygen.

This dataset includes discrete profile measurements of delta carbon-13, delta oxygen-18, temperature, salinity and dissolved oxygen collected during the R/V Garcia del Cid cruise EUROFLEETS_Iberia-Forams (EXPOCODE 29GD20120910) in the North Atlantic Ocean from 2012-09-10 to 2012-09-15.

The fourth Gulf of Mexico Ecosystems and Carbon Cycle (GOMECC-4) Cruise took place on board the NOAA Ship Ronald H. Brown, from September 13–October 21, 2021. The cruise departed from Key West, FL into the Gulf of Mexico and then around the coastal waters of the Gulf of Mexico in a counter-clockwise direction, ending in St. Petersburg, FL. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, biogeochemical and biological parameters as they relate to ocean acidification (OA) in the coastal realm. This was the fourth occupation of the Gulf of Mexico as part of OAP’s monitoring efforts in the region, with the previous ones occurring in 2007, 2012, and 2017. The cruise included a series of 15 transects approximately orthogonal to coast of the Gulf of Mexico and a 16th partial transect along the 27°N line, between Florida and the Bahamas, as well as a comprehensive set of underway measurements. This dataset includes the processed, 1db-binned CTD profile data collected in the 141 stations.

The second Gulf of Mexico and East Coast Carbon (GOMECC-2) Cruise on board NOAA Ship Ronald H. Brown from Miami, took place in the Gulf of Mexico and then along the East US coast to Boston. The effort was in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP). The cruise was designed to obtain a snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. This was the second occupation, with the first occurring in 2007, and complemented mooring time series and other regional OA activities. The cruise included a series of 8 transects approximately orthogonal to the Gulf of Mexico and Atlantic coasts and a comprehensive set of underway measurements along the entire transect.

The NOAA Hypoxia Watch project provides near-real-time, web-based maps of dissolved oxygen near the sea floor over the Texas-Louisiana continental shelf during a period that extends from mid-June to mid-July. The NOAA National Marine Fisheries Service Mississippi Laboratories at Pascagoula and Stennis Space Center and the NOAA's National Centers for Environmental Information (NCEI) began the Hypoxia Watch project in 2001. Scientists aboard the NOAA Research Vessel Oregon II measure seawater properties, such as water temperature, salinity, chlorophyll, and dissolved oxygen, as the Oregon II cruises the waters south of Pascagoula, MS and then makes its way from Brownsville, Texas, to the mouth of the Mississippi River. A scientist aboard the ship processes the measurements from electronic dissolved oxygen sensors, checks the measurements periodically with chemical analyses of the seawater, then sends the data by FTP to the NCEI approximately every three to four days. Physical Scientists at NCEI transform the dissolved oxygen measurements into contour maps, which identify areas of low oxygen, or hypoxia. During the cruise, as the data is received from the ship, NCEI generates new maps and publishes them on the web. The first map will usually cover an area off the Mississippi coast, successive maps will add areas of the continental shelf from Brownsville to Corpus Christi, and the final map will usually cover the entire Texas-Louisiana-Mississippi coast. Maps are published every three to four days from approximately June 22 to July 20.

This dataset contains the surface underway biological oxygen saturation data of the third dedicated East Coast Ocean Acidification cruise (GOMECC2021). The cruise took place September from 2021-09-14 to 2021-10-20 aboard the NOAA Ship Ronald H. Brown in the Gulf of Mexico. The cruise was designed to obtain a synoptic snapshot of key carbon, physical, and biogeochemical parameters as they relate to ocean acidification (OA) in the coastal realm. This effort was conducted in support of the coastal monitoring and research objectives of the NOAA Ocean Acidification Program (OAP).
