Vmes on the Corner Seamounts] NAFO
Vulnerable Marine Ecosystems Database Newfoundland Seamounts Geographical reference Northwest Atlantic Management Body/Authority Northwest Atlantic Fisheries Organization (NAFO) Area Type Seamount closure (NAFO) Closed since 2007-01-01 until 2021-12-31 Habitat and Biology General Biology Seamounts are uniquely complex habitats that rise into bathyal and epi-pelagic depths. In general seamounts, owing to their isolation tend to support endemic populations and unique faunal assemblages. Physical description of the environment: Seamounts Newfoundland Seamounts consist of 6 peaks with summits all deeper than 2400 m, with most of the area being deeper than 3500m. The Newfoundland seamounts were volcanically active in the late Cretaceous period. Named seamounts include Shredder and Scruntion.

360. How Many Hours in a Day? 24
With this in mind we can discuss how one can finds one longitude. How many degrees are there in a circle? 360. How many hours in a day? 24. So how many degrees are there in an hour? (divide 360 by 24 and the answer is 15). So for every hour away from the p rime meridian you are 15 degrees away from it. Ships would take a chronometer or a clock on the ship set at the time at the Prime Meridian. When the sun was directly overhead on the ship, the navigator would know it was “noon” and look at the clock which might say 1300 hours (1 p.m.) So there is an hour difference in time between the ship and London. This would mean that the ship is 15 degrees west of the prime meridian. Charles Darwin Darwin traveled on a ship called “The Beagle” captained by Robert Fitzroy. The ship was to undertake a journey that would last nearly 5 years. The ship left on 27 Dec, 1831. Charles Darwin as naturalist whose job, basically was to disprove the idea of evolution which was growing in popularity at the time. Darwin made two significant hypotheses on the trip. One had to do with his theory of reef formation, The other had to do with the idea of biological evolution. We deal here with the first of the two – reef formation First. What is a reef made of? Largely coral. What is coral? Coral is an animal belonging to a phylum called Cnidaria. This phylum contains animals which are sessile (don’t move) like sea anemones and corals and well as some organisms which are motile (can move) like jelly fish. -
Review of the Impact Assessment Agency's Draft Regional
Canadian Science Advisory Secretariat Newfoundland and Labrador Region Science Response 2020/033 REVIEW OF THE IMPACT ASSESSMENT AGENCY’S DRAFT REGIONAL ASSESSMENT OF OFFSHORE OIL AND GAS EXPLORATORY DRILLING EAST OF NEWFOUNDLAND AND LABRADOR Context The Impact Assessment Agency (IAA), in collaboration with Natural Resources Canada and the Newfoundland and Labrador (NL) Department of Natural Resources, and guided by a Committee appointed by the Minister of Environment and Climate Change Canada (ECCC), is developing a Regional Assessment (RA) pertaining to offshore oil and gas exploratory drilling east of Newfoundland and Labrador. The final Agreement to Conduct a Regional Assessment of Offshore Oil and Gas Exploratory Drilling East of Newfoundland and Labrador (hereafter referred to as “the Agreement”) was signed on April 15, 2019 between Her Majesty the Queen in Right of Canada as represented by the federal Ministers of the Environment and Natural Resources and Her Majesty the Queen in Right of Newfoundland and Labrador, as represented by the provincial Ministers of Natural Resources and Intergovernmental and Indigenous Affairs. On the same date, a joint committee was established between the Governments of Canada and Newfoundland and Labrador. The roles of the Committee, as well as the Task Team and the Technical Advisory Group are described in the Agreement. The RA is intended as a Regional Study pursuant to the Canadian Environmental Assessment Act (CEAA 2012) and will assess the potential effects of existing or future physical activities carried out in the Study Area (see Figure 1) which contains multiple current and proposed oil and gas exploration and production activities. The focus of the RA is to bring together existing and available data on the environmental setting of the Study Area, in order to provide a general, regional-scale description of key environmental components at a level of detail that is considered useful and appropriate for the purposes of the RA. -

Template for Submission of Scientific Information to Describe Areas Meeting Scientific Criteria for Ecologically or Biologically Significant Marine Areas Title/Name of the area: Canyons and Seamounts of the Northwest Atlantic Ocean within and beyond national jurisdiction Presented by: Lisa Speer, Director, International Oceans Program, Natural Resources Defense Council Peter Auster, Senior Research Scientist, Sea Research Foundation and Research Professor Emeritus, University of Connecticut. Introduction: Submarine canyons and seamounts off the Atlantic coast of the United States and Canada provide foraging, breeding, and/or nursery habitats for hundreds of fish and crustacean species, including swordfish, tuna, and sharks; marine mammals including endangered sperm whale, beaked whales, and dolphins; and isolated invertebrate communities including those dominated by deep sea corals and sponges. Location: Submarine canyons off the Atlantic coast of the United States and Canada occur mostly within the zones of national jurisdiction. Four of the New England Seamounts are within the jurisdiction of the United States. The remaining New England Seamounts and all of the Corner Rise Seamounts are located in ABNJ. See maps (links below). Feature description of the proposed area The varied seafloor topography and complex oceanographic influences of canyons and seamounts combine to create unique habitat for many species of corals, sponges and other invertebrates on the benthos and fish, marine mammals and birds in the pelagic realm. Deepwater canyons are a striking feature of the continental margin off the east coast of the United States and Canada. There are 15 major canyons in the United States alone, ranging in depth from about 200 meters to about 3,500 meters. -

Comdoc17-16 Revisionneseamountsclosure
Northwest Atlantic Fisheries Organization Serial No. N6741 NAFO/COM Doc. 17-16 [Adopted] 39th ANNUAL MEETING OF NAFO - SEPTEMBER 2017 Revision of New England Seamounts Closure Explanatory memorandum Under the revised NAFO convention, NAFO members have recommitted themselves to applying an ecosystem approach to fisheries management, including conserving the marine biodiversity within NAFO waters. This responsibility to ensure sustainable fisheries and safeguarding the marine environment has been reflected in NAFO’s efforts to protect vulnerable marine ecosystem elements, such as seamounts and their associated fisheries. In 2014, the Scientific Council recommended expansion of the seamount protection zones surrounding the New England and Corner Rise Seamount chains located within the NAFO Regulatory Area (SCS 14/17 REV). With regards to the New England and Corner Rise seamount chains, the SC recommended that the polygons be expanded to include all relevant seamounts. Subsequently, and as directed by the Commission at its 2016 annual meeting, the Joint Commission-Scientific Council Working Group on Ecosystem Approach Framework to Fisheries Management (WG-EAFFM) gave consideration to the boundary of the New England Seamounts at its July 2017 meeting. While no proposal for amendment of the current polygon was developed, there was a general agreement that the peaks shallower than 2000m must be protected. The WG also recognized that the current seamount closures included very large areas that do not contain seamounts. Therefore, and on this basis, the United States and Canada propose refining the boundary of the New England Seamounts closure reducing the overall footprint to 178 535 km2, compared to the original closure area of 275 225 km2. -

Title/Name of the area: Madeira – Tore Presented by Maria Ana Dionísio (PhD in marine sciences), with a grant funded by Instituto da Conservação da Natureza e das Florestas and ISPA - Instituto Universitário de Ciências Psicológicas, Sociais e da Vida, [email protected] Pedro Ivo Arriegas, Instituto da Conservação da Natureza e das Florestas, [email protected] Abstract (in less than 150 words) Madeira-Tore EBSA includes a total of 17 seamounts. Seamounts are hotspots of marine life and in general they represent areas of an enhanced productivity, especially when compared with nearby abyssal areas. This EBSA has a total area of 197431 km2 with depths ranging from 25m (top of Gettysburg seamount) to 4930m (bottom of Tore seamount). The area includes a proposed Site of Community Importance - Gorringe Bank and an OSPAR High Seas Marine Protected Area – Josephine seamount. All structures included in the Madeira-Tore EBSA fulfill four or more out of the seven EBSA scientific criteria. A total of 965 species are present in this EBSA of which 7% are protected under international or regional law. Introduction (To include: feature type(s) presented, geographic description, depth range, oceanography, general information data reported, availability of models) The Madeira-Tore EBSA includes a total of 17 seamounts (Ampere, Ashton, Coral Patch (northern part of), Dragon, Erik, Gago Coutinho, Godzilla, Gorringe Bank (Ormond and Gettysburg seamounts), Hirondelle II, Josephine, Lion, Pico Pia, Tore, Seine, Sponge Bob, and Unicorn). These seamounts present particular features which make this area eligible as an EBSA when assessed against the EBSA scientific criteria. Benthic biological communities on seamounts are highly vulnerable to human activities. -
