Overview Marine Minerals Program
Non-Energy Marine Minerals Primarily Sediment/Sand for Beach Nourishment and Coastal Restoration Atlantic and Gulf of Mexico National OCS Sand Inventory Marine Mineral Information System (MMIS) Negotiated Noncompetitive Agreements Competitive Leasing
3
Strategic Direction Identify, Assess, and Sustainably Manage OCS Mineral Resources Understand the Uncertainty and Environmental Risk w/ Individual and Cumulative Leasing Areas w/ Limited Resources Conflicts w/ Other Uses (ex., oil and gas infrastructure, telecom cables, fisheries)
4
Strategic Science Questions
How Best Assess Cumulative Effects? What is Effect of Dredging on Habitat or Landscape Alteration and Ecological and Cultural Resources? How Better Use Existing or Emerging Technologies? What are Best Resources, Measures, and Systems for Long-Term Monitoring?
5
Information Needs Effects of Impacting Activities and How to Prevent or Lessen Adverse Impacts Characterize Affected Resources Cumulative Impacts Monitoring Compliance
6
Offshore Dredging
7
Impacts Hopper Dredge Tracks
8
Impacts Fish and Benthic Habitat T&E Species – esp., Sea Turtles
Offshore Sediment Transport Transport Pathways Following Beach Placement
