Zack Klyver, Marine Mammal Scientist, Educator, and Conservationist. Advisor and Consultant, Blue Green Future. President, FLUKES: International Whale Tours will present Cashes Ledge; The Yellowstone of the North Atlantic. In July 2024, Conservation Law Foundation submitted nomination papers to NOAA to create a Cashes Ledge National Marine Sanctuary. The proposed sanctuary is 766 square miles in size with 194 miles being completed protected. It would encompass the underwater mountain range, ledges, ridges, and surrounding deep water basins. This massive range of ledges creates upwellings of cold nutrient-rich water that fuel an explosion of plankton, that feed herring, squid, and mackerel, who in turn are prey for tuna, sharks, seabirds, and a high diversity of marine mammals. Cashes holds the deepest and densest kelp forest on the Eastern Seaboard and an environment abounding in fish including a red-colored cod and exceptional benthic life. Research and Whale tours have observed Basking sharks, ocean sunfish, finback whales, 51 species of birds, a large Leatherback Sea Turtle and an exuberant pod of nearly 100 Common Bottlenose dolphins.
