To investigate this, the USGS participated in cruises in the West Florida Shelf and northern Gulf of Mexico regions aboard the R/V Weatherbird II, a ship of opportunity lead by Dr. Kendra Daly, of the University of South Florida (USF). This cruise occurred May 03 - 09, 2011, leaving from and returned to Saint Petersburg, Florida. The USGS collected data pertaining to pH, dissolved inorganic carbon (DIC), and total alkalinity in discrete samples. Thirty-four underway discrete samples were collected approximately hourly over a span of 1632 kilometer (km) track line, additionally 44 discrete samples were taken at four stations, these were taken at various depths. Flow-through conductivity-temperature-depth (CTD) data were collected, which includes temperature, salinity, and pH. Corroborating the USGS data are the vertical CTD profiles collected by USF, using the following sensors: CTD, oxygen, chlorophyll fluorescence, optical backscatter, and transmissometer. Additionally, discrete depth samples for nutrients, chlorophyll, and particulate organic carbon/nitrogen were collected. Purpose: The purpose is to study the effects of climate change on ocean acidification within the Gulf of Mexico. Supplemental_Information: The USGS Saint Petersburg Coastal and Marine Science Center (SPCMSC) - St. Petersburg, FL, assigns a unique identifier to each cruise or field activity. For example, 11BHM01 tells us the data were collected in 2011 for Benthic Habitat Mapping and the data were collected during the first field activity for that project in that calendar year. Refer to http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html for a detailed description of the method used to assign the cruise ID.

Completeness_Report: These data are collected along tracklines (2-D) and therefore are inherently incomplete. There are no data collected between tracklines. Lineage: Process_Step: Process_Description: A YSI 6600 conductivity-temperature-depth (CTD) sonde coupled with a YSI 650 Multi-Parameter Display System (MDS) was deployed to provide temperature and salinity values for water chemistry calculations during the cruise. Seawater scale pH values were also recorded. The sonde was located in the wet lab of the R/V Weatherbird II. The sonde was attached to a seawater flowthrough system that siphoned water from approximately 4 feet below the water surface. The flow rate varied somewhat with weather condition and turned off in 6 foot and higher waves. Data values were logged at 5 minute intervals. The ships cruising speed was 9 knots. Process_Date: 20110503 Process_Step: Process_Description: Data exported from YSI 650 MDS and converted to comma deliminated file (CDF) within EcoWatch software. These data were imported into Microsoft Excel and formatted into a single spreadsheet. Data from GPS with latitude/longitude were joined to water parameters using time and date stamps.

Additionally, the GPS data was taken from the Weatherbird II's navigation logs and was matched with the time logs on the sonde. These data have not been QA/QC yet, and as such could have data errors due to tubes clogging, or flowthrough shutdown for inclement weather.
