Abstract:

This dataset consists of Pb-210 activity measurements from sediment cores taken throughout the northern Gulf of Mexico with relation to the Deepwater Horizon. Short-lived radioisotope measurements and geochronological model calculations follow those presented in Brooks GR, et al. (2015) Sedimentation Pulse in the NE Gulf of Mexico following the 2010 DWH Blowout. PLoS ONE 10(7): e0132341. doi:10.1371/journal.pone.0132341. Samples were analyzed by gamma spectrometry on Canberra HPGe (High-Purity Germanium) Coaxial Planar Photon Detectors for total 210Pb (46.5Kev), 214Pb (295 Kev and 351 Kev), and 214Bi (609Kev) activities. Data were corrected for counting time and detector efficiency, as well as for the fraction of the total radioisotope measured yielding activity in dpm g-1 (disintegrations per minute per gram).

Purpose:

This dataset was developed to determine the Pb-210 activity from 1900-2013 as a sedimentary tracer of Marine Oil Snow Sedimentation and Flocculent Accumulation (MOSSFA) related to subsurface petroleum releases in the Gulf of Mexico. It was also created to determine the spatial extent of MOSSFA processes in the northern Gulf of Mexico following the Deepwater Horizon event.

The data in the Excel spreadsheet titled "CIMAGE NGOM Pb-210 Inventory Data" are organized by core sample, with each tab in the spreadsheet representing an individual core used in the analysis. The names of the tabs and cores are a combination of the cruise name and the name of the site where the core was collected. For example, a tab labeled “1114DSH08” indicates that the core is from Cruise 1114 and Station DSH08. Please note that not all cruise names correspond with the date of the cruise. Below is a list of cruise names and the dates when they occurred:
          
1109 (November 2010); 1110 (December 2010); 1114 (February 2011); 1125 (June 2011); 0911 (September 2011); 0412 (April 2012); 0812 (August 2012); 1012 (October 2012); 0813 (August 2013);
          
The following are the data parameters reported in each tab:
          
Core No. – Unique Identifier for core sample (ID); Center Pt. Depth – Depth of core sample (cm); Excess Pb-210 Activity +/- (dpm/g); Excess Pb-210 Activity (dpm/g); Dry Bulk Density (g/cm3);
          
The Excel file titled “Site Location and Date of Collection” contains information about the locations where the samples were collected. The following are the data parameters reported in file:
          
Site Name – Name of location were sample was collected (text); Date Collected (month / year); Latitude (DD.DD); Longitude (DD.DD); Water Depth (m); Distance from DWH (km); 210Pbxs Flux, 2010-2013 (dpm cm-2 yr-1); 210Pbxs Flux, 1950-2009 (dpm cm-2 yr-1); 210Pbxs Flux, 1900-1949 (dpm cm-2 yr-1); Total 210Pbxs Inventory (dpm cm-2);|||||
