***************************************************************** Journal for accession number: 0069074 Created on: 2011-06-01 21:45:24 UTC By: Christopher Paver,OC1,SSMC3 4637,7133272 x118 Source: Original data were collected as part of the response to the MC252 Deepwater Horizon oil spill event. Data may have been provided by the Subsurface Monitoring Unit (SMU), BP, EPA, DFO Canada (Department of Fisheries and Oceans), or various labs that completed sample analysis. Actions: The original data were copied into the data/0-data/ directory. Subsequent processing was performed on the CTD data set at the National Coastal Data Development Center using Sea-Bird SEASOFT software (http://www.seabird.com/software/softrev.htm) as documented below: - Steps to Process CTD data - Steps to Reprocess CTD data for upcasts and bottles - Steps to Reprocess CTD data including the wild-edit option Processed data (bin-averaged ASCII files) were transformed into NetCDF format. All transformed data were then copied into the data/1-data/ directory. Files: about/ This directory contains files generated by NODC with ancillary information about the data submission. DWH_JF_Cruise_03.xml - Metadata record for the archived data, in Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (FGDC-STD-001-1998) XML format with remote sensing extensions. DWH_JF_Cruise03_processedCTD_NODC.xml - Instrument level metadata record for the archived CTD data, in Federal Geographic Data Committee (FGDC) Content Standard for Digital Geospatial Metadata (FGDC-STD-001-1998) XML format with remote sensing extensions. CTD_Process_CTD_Data.pdf - This document describes the steps used by NCDDC personnel to process the data in the ctd/ directory. 0069074_lonlat.txt - Contains sample locations for these data. Each row contains the geographical position where these data were collected (longitude in the left column and latitude in the right column, both in decimal degrees). NODC may have corrected geographic positions that seemed to be in error when generating this file. However, NODC did not change the original data files under the directory data/0-data/. 0069074_map.jpg - Sample location map for these data. dirinfo.txt - A text file, which contains the ship's call sign and cruise ID of data collection, to facilitate NODC's online dissemination of this data set. plugin-SMU+Data+Management+Guidance+v4_04.pdf - These documents provide guidance to research vessel data managers to fulfill Area Commands data management requirements and data specifications including deliverables, data flow, information management and data specifications. By ensuring consistency between vessels, cruises and samples of recorded datasets, post sampling processing and analysis can be accelerated. The data management guidance evolved over time and was not typically submitted with the daily deliverables, therefore archived data management documents don't necessarily reflect the exact guidance followed on that cruise. data/0-data/ This directory contains the data files as submitted to NOAA by various ships in accordance with SMU Guidance. Various levels of compliance with SMU guidance were achieved, with increased compliance over time. Some data may be in Sea-Bird proprietary formats (e.g., hexadecimal files). There is little or no precise documentation as to shipboard processing steps. The column labeled Analyte in the analytical chemistry data file may contain values similar to 0.1mm. These values are typically associated with sediment sampling, however, samples taken at the water/seafloor interface may have been tagged as a water matrix but included sediment results as well. The column labeled Analyte in the analytical chemistry data file may contain one or more instances of the variable Tentatively Identified Compound. Tentatively Identified Compound (TIC) is assigned when compounds don't meet the complete identification requirements. These are specific EPA requirements that the labs use in their analysis and reporting. Using a GC/MS, when the library is searched for the unknown compound, can frequently give a tentative identification to the unknown; hence the name Tentatively Identified Compound. In some cases the TIC is identified as a class of compounds (e.g., alkane). data/1-data This directory contains the data files processed at NODC/NCDDC in accordance with documented standards. Sea-Bird hexadecimal files processed with SEASOFT software and transformed to NetCDF are in this directory. Documentation or processing specifications is provided in the about/ directory for reference. ***************************************************************** NODC accession number: 0069074 Version: 4.5 Updated on: 2012-03-26 16:57:45 UTC By: Christopher Paver,OC5,SSMC3 4637,7133272 x118 Updates were received for this data set.
