Description:

Abstract:: These data describe debris items identified via sidescan sonar surveys carried out by contractors to NOAA?s Office of Coast Survey as part of the Gulf of Mexico Marine Debris Project (GOMMDP). These surveys are intended to locate marine debris in nearshore areas of the northeastern Gulf of Mexico deposited by hurricanes Katrina and Rita in 2005.
Purpose:: These data describe debris items and are intended, in conjunction with data describing the boundaries of surveys, to provide users with information regarding the distribution and nature of marine debris in the area.
Supplemental_Information:: During the 2005 hurricane season, hurricanes Katrina and Rita inflicted severe damage on the Gulf of Mexico (GOM) coastal region, and deposited huge amounts of debris over large areas of the Gulf coast. Submerged marine debris poses a hazard to vessel traffic and can adversely affect commercially viable fishing grounds. To address the submerged debris problem, Congress appropriated funds to survey areas potentially affected by submerged marine debris, tasking NOAA?s Office of Coast Survey and Office of Response and Restoration to conduct the surveys, compile and disseminate data in an effective and useable format, and carry out other outreach activities specific to this project.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Attributes included in these data describe item location, dimensions, depth, and type. No formal attribute accuracy assessment has been conducted, but data quality is estimated to be good.

Logical_Consistency_Report:

These data have been assembled from data derived from interpretation of sidescan sonar imagery by contractors to NOAA's Office of Coast Survey.

Completeness_Report:

These data represent the best available composite of debris items available at the time of publication, but users should be aware that survey and analysis progress are irregular. Users should check frequently with the data distributor for updates.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Debris item locations were interpreted from sidescan sonar imagery of unknown provenance. No formal spatial accuracy assessment has been conducted, but data quality is estimated to be good.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:: These data were attributed with height and depth information via heights interpreted from sidescan sonar imagery of unknown provenance, nautical charts, and in some cases, echosounder depths. No formal vertical accuracy assessment has been conducted, but data quality is estimated to be adequate.
