Byrne Xuewu Liu 2012 HLY1001_Averaged vector digital data Data Series 748 St. Petersburg, FL U.S. Geological Survey http://pubs.usgs.gov/ds/748/pubs748/index.html Models project the Arctic Ocean will become undersaturated with respect to carbonate minerals in the next decade. Recent field results indicate parts may already be undersaturated in late summer months when ice melt is at its greatest extent. However, few comprehensive data sets of carbonate system parameters in the Arctic Ocean exist. Researchers from the U.S. Geological Survey (USGS) and University of South Florida (USF) collected high-resolution measurements of pCO2, pH, total dissolved inorganic carbon (DIC), total alkalinity (TA), and carbonate (CO3-2) from the Canada Basin that fill critical information gaps concerning Arctic carbon variability. A Multiparameter Inorganic Carbon Analyzer (MICA) was used to collect approximately 9,000 measurements of air and sea pCO2, pH, and DIC along a 11,447-km trackline in August and September 2011. In addition, over 500 discrete surface water samples were taken. These data are being used to characterize and model regional pCO2, pH, and carbonate mineral saturation state. A high-resolution, three-dimensional map of these results will be presented. Data collected on the August 2011 Arctic Cruise will be used to create regional maps of seawater carbonate parameters, including pCO2 flux/change maps, and derivative maps on saturation state. Maps depicting pCO2 and carbonate saturation states over large latitudinal and nearshore to offshore gradients are needed for the Arctic, where significant decline of carbonate ecosystems, habitats, and calcifying organisms are predicted over the next decade. The data will allow the USGS to map variations in ocean chemistry along designated tracks and will be used in models to predict future Arctic Ocean saturation states. 20110801 ground condition Complete None planned -179.99 -179.99 88.46 56.14 USGS Metadata Identifier USGS:2d738e27-d796-42e6-8319-b1fac7e9ca6f Ocean Chemistry Ocean Acidification pCO2 total carbon carbon flux pH Salinity Temperature Data Categories for Marine Planning assessments water column features Marine Realms Information Bank (MRIB) Keywords chemical analysis chemical oceanography ocean acidification USGS Thesaurus chemical analysis marine chemistry ocean acidification Geography Arctic Ocean Canada Basin Alaska Canada Water seawater ocean surface Year 2011 none Please acknowledge the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center as a data source in products developed from these data, and such acknowledgment as is standard for citation and legal practices for data source is expected by users of this data set.
