Mapping the Impacts of Marine Debris Left in the Wake of Hurricane Katrina
61st Interdepartmental Hurricane Conference7 March, 2007
Brendan M. BrayNOAA Marine Debris Program
Gulf of Mexico Marine Debris Project
Background• Hurricane Katrina impacts• Major shipping channels were surveyed and cleared• Near shore fishing and recreation areas had not
been surveyed• Funding from Congress to NOAA
Gulf of Mexico Marine Debris Project Goals • Support improvement of fishing and recreational conditions• Support efficient and cost-effective debris removal • Public outreach to regional stakeholders
Project GIS and Mapping Products
• Project Web siteo Maps and data
o Photos and graphics
o Links to partner organizations
o Relevant publications and media
• Integrated debris database
• Static maps (PDF format) depicting location of debris found, debris dimension, sounding depth, clearance depth, etc.
• Internet Map Server (IMS)
Static map of entrance to Biloxi Bay, MS
http://gulfofmexico.marinedebris.noaa.gov• Marine debris maps and
data for each survey zone
• Internal /external links to project partners
• Media information, related publications, photos, and video
• Link to interactive internet mapping server (Arc IMS)
Future Applications• Marine Debris Density Model
OBJECTIVE: Increase efficiency of post-incident response to marine debris.
Debris density can be estimated using widely available information: • hurricane track • coastal zone population data • coastal damage polygons• general information on currents and winds • data depicting environmental sensitivity
Model depicts debris density surface derived from actual survey data; 2006 / 2007
Actual survey coverage in pink with identified debris items to date (black)
FEMA damage polygons: Red – catastrophic damage ; Orange – extensive damage; Yellow – moderate to light damage
Debris Impacts and Environmental sensitivity
