March 29, 2016 – WASHINGTON (Saving Seafood) – This morning, the “Protect New England’s Ocean Treasures Coalition” released an analysis of Northeast ocean areas under consideration for designation as marine National Monuments. The analysis was conducted by Dr. Peter Auster of Mystic Aquarium and Dr. Scott Kraus of the New England Aquarium, and was presented in a press webinar organized by the Pew Charitable Trusts.
Dr. Auster and Dr. Kraus concluded, among other findings, that the proposed monument areas possess high habitat diversity and an abundance of species, function as a source of habitats including for commercial species, and contain species sensitive to disturbance. However, they noted that they do not have adequate data to address what the economic and human effects of area closures to fisheries might be. Presenters also acknowledged that the areas under consideration are already protected, but expressed concern about the future possibility of drilling and mining.
A monument designation would likely affect the fisheries for Atlantic red crab, offshore lobster, squid, mackerel, butterfish, tilefish, albacore wahoo, dolphinfish (mahi mahi), and others. Pelagic longline, rod and reel, and greenstick fisheries including yellowfin tuna, bluefin tuna, bigeye tuna, and swordfish may also be affected. During the webinar, the presenters conceded that they do not have enough data to analyze how a monument designation would affect many of these fisheries.
The analysis addressed both Cashes Ledge and the Northeast Seamounts and Canyons. White House officials stated last week that Cashes Ledge is “not under consideration for a [national monument] designation at this time.” However, representatives of the Northeast Seafood Coalition and Associated Fisheries of Maine, who attended meetings with White House officials, said in a joint statement that offshore canyon areas east of Cape Cod remain under consideration and “affected fishermen should remain vigilant in assuring that any concerns they may have are addressed.”

Proposed Marine National Monument in Northeastern Waters of the U.S.
These maps illustrate that while whale and dolphin species are distributed throughout the whole Cashes Ledge region, the deep water toward the center of the proposed monument area is a hot spot for both the total numbers of species (left) and the total numbers of animals (right).

This map illustrates the pattern of species richness (number of species) of bottom-dwelling animals in the Cashes Ledge area. Warmer colors indicate more species. The largest red diversity hot spot is the peak of Cashes Ledge, where the largest continuous kelp forest on Cashes Ledge is located. Note that this map displays number of species, not numbers of individuals or density of animals. Courtesy of Peter Auster and Michel McKee, Mystic Aquarium
Topographic roughness – essentially, small-scale bumpiness of the seafloor – is linked to the distribution and diversity of microhabitats that in turn support a diversity of species. Warmer colors indicate greater “roughness” and are linked to locations of species-rich communities. For example, the area of high roughness on the top of Cashes Ledge (right inside the proposed monument boundary) is where the kelp forest is located and a species diversity hotspot.

These maps illustrate patterns in the richness of species (left) and total numbers of whales and dolphins (right) observed during surveys in the Northeast Canyons and Seamounts region. Warmer colors indicate greater richness or abundance. Note how species concentrate on the eastern Georges Bank, where the shelf descends into the deep ocean, and hot spots for concentrations of whales and dolphins dot the shelf-edge.

This map shows hot and cold spots for species of bottom-dwelling animals in the New England Canyons and Seamounts areas. Species are especially diverse along the edge of Georges Bank, where the shelf descends into the deep ocean. Hot spots are also visible on Bear, Physalia, Retriever and Mytilus Seamounts.

Warmer colors indicate greater “roughness” and are linked to locations of species-rich communities. A high topographic roughness value suggests where especially rich communities may be found. The entire shelf-edge, where Georges Bank descends into the deep ocean, is topographically rough, and Bear, Physalia, Retriever and Mytilus Seamounts stand out.
