Anchoring Impacts to Resources (Updated 5/1/2010)
Maritime heritage resources of Thunder Bay National Marine Sanctuary (TBNMS or Sanctuary) are being damaged by recreational boat anchoring.
Boundary Expansion (Updated 5/1/2010)
The Thunder Bay National Marine Sanctuary (TBNMS or Sanctuary) is considering expanding from 448 square-miles to over 4,085 square miles. The expansion area is a nine fold size increase and expands the Sanctuary from one county to three.
Impacts of On-water Recreation (Updated 5/1/2010)
The Thunder Bay National Marine Sanctuary (TBNMS or Sanctuary) does not have data on the quantity and distribution of recreational diving, snorkeling and kayaking in the sanctuary. This data is essential for determining both positive and negative impacts on sanctuary resources, as well as positive impacts on the local and regional economy.
Socioeconomics - Visitor Centers (Updated 5/1/2010)
The Thunder Bay NMS (TBNMS) operates NOAA's Great Lakes Maritime Heritage Center (GLMHC) and hosts a wide range of visiting researchers. The economic effects of these activities on the local and regional community need to be studied, quantified and used to inform future management decisions. Further, should sanctuary expansion occur, this analysis will help the sanctuary determine what kind of interpretive presence it should maintain in communities outlying Alpena.
