Information on Low Profile Groundline Workshops

NOAA' National Marine Fisheries Service (NMFS) conducted a series of fact finding/scoping workshops from Maine to North Carolina during the last two weeks of September 2005 to help assess the feasibility of requiring low profile groundline for fisheries regulated by the Atlantic Large Whale Take Reduction Plan (ALWTRP). Low profile groundline is considered to be any groundline that is not sinking or neutrally buoyant but which maintains a “low profile” in the water column as compared to traditional floating groundline. These workshops were information gathering whereby information, ideas or recommendations from individual participants and the public were collected.

  Goals and Objective
 

NOAA Fisheries Service conducted a series of fact finding/scoping workshops along the East Coast to identify:

  1. Areas where low profile groundline should be considered;
  2. Appropriate height above the ocean bottom (based primarily on bottom type, but will include the limited information available on whale behavior);
  3. Techniques to modify groundline;
  4. Gear marking options for low profile areas; and
  5. Contingency plan ideas in the event of an entanglement occurs in low profile groundline.

The current knowledge of large whale (right, humpback and fin) ecology (including foraging and diving behavior), prey, habitat and oceanography in various areas were discussed in the context of low profile groundline. A proxy height for specific areas were discussed until large whale ecology information is available to further refine the concept of low profile groundline. These workshops were information gathering whereby information, ideas or recommendations from individual participants and the public were provided. Summaries from these meetings were provided to the Atlantic Large Whale Take Reduction Team (ALWTRT) and discussed during the December 2006 ALWTRT meeting.
