North Atlantic Tracks for the westbound crossing of February 24, 2017, with the new RLAT Tracks shown in blue. The North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), are a structured set of transatlantic flight routes that stretch from eastern North America to western Europe across the Atlantic Ocean, within the North Atlantic airspace region.
Major fractures zones of the Atlantic can be seen on this ocean depth map Active Atlantic Ocean fracture zones are perpendicular to the mid-ocean ridges (black lines) in orange shaded region In the Atlantic Ocean most fracture zones originate from the Mid-Atlantic Ridge , which runs from north to south, and are therefore west to east oriented ...
Mid-Atlantic Ridge. The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian Plate and the African Plate, north and south of the ...
North Atlantic Track Agreement. The North Atlantic Track Agreement was an agreement in November 1898 [1] among thirteen passenger steamship companies to use a set series of trans-Atlantic routes that stretched from the northeast of North America to western Europe for the Atlantic crossing. Following the tracks was recommended but not compulsory.
The Atlantic Seaboard Fall Line, or Fall Zone, is a 900-mile (1,400 km) escarpment where the Piedmont and Atlantic coastal plain meet in the eastern United States. [2] Much of the Atlantic Seaboard fall line passes through areas where no evidence of faulting is present. The fall line marks the geologic boundary of hard metamorphosed terrain ...
Midcontinent Rift System. The Midcontinent Rift System (MRS) or Keweenawan Rift is a 2,000 km (1,200 mi) long geological rift in the center of the North American continent and south-central part of the North American Plate. It formed when the continent's core, the North American craton, began to split apart during the Mesoproterozoic era of the ...
The pass starts from just northeast of the island of Newfoundland over the North Atlantic Ocean to central Africa, over South Sudan. The Atlantic Ocean is the second-largest of the world's five oceanic divisions, with an area of about 85,133,000 km 2 (32,870,000 sq mi). [2] It covers approximately 17% of Earth's surface and about 24% of its ...
the north line; the arc line; the 39°43′ N parallel; The most difficult task was fixing the tangent line, as they had to confirm the accuracy of the transpeninsular line midpoint and the 12-mile circle, determine the tangent point along the circle, and then actually survey and monument the border. They then surveyed the north and arc lines.
