A Warming Hole in North Atlantic Ocean August 4, 2020 This phenomenon, known as a ‘warming hole’, has been partly attributed to a slowdown in the thermohaline circulation or Atlantic meridional overturning circulation (AMOC) – a deep-ocean process that plays a key role in the heat transport in Earth’s climate.

GLANAM (Glaciated North Atlantic Margins) is an Initial Training Network (ITN) funded under the EU Marie Curie Programme. The Atlantic Meridional Overturning Circulation (AMOC) is a key component of the global climate system, and dominates northward ocean heat transport over most of the Atlantic. The Multibeam Bathymetry Database (MBBDB) at NCEI collects and archives multibeam data from the earliest commercial installations (circa 1980) through today's modern high-resolution collections. The principal feature of the bottom bathymetry (terrain) of the Atlantic Ocean is a submarine mountain range called the Mid-Atlantic Ridge. •The study of bathymetry determines ocean depths and ocean floor topography. Note the prominant Mid-Atlantic Ridge running centrally between the continents. The OSNAP array is an observing system between Scotland and Labrador, Canada which provides continuous measurements of heat and freshwater transport in the North Atlantic Subpolar gyre. The North Atlantic Current (NAC) is found at the boundary between the cooler waters closer to Canada and warmer waters east of 50°W to 40°W.

Oversized Plate (PDF, 42x33 inches, 10.8 Mb) Bathymetry datasets identified in the North East Atlantic (NEA) for the integration in the global database. From a few such measurements, the fi rst bathymetric map was produced and published by Maury in the 1853 Wind and Current Charts of the North Atlantic Ocean (Fig. 1A). Although this particular map was not very accurate, many important seafl oor features were dis- covered from such measurements. The developed digital elevation models (DEMs) represent a high-detailed bathymetry of the Canary Basin and the Kane Gap. Thus bathymetric measurements can determine the topography of the ocean floor, and have shown that the sea floor is varied, complex, and ever-changing, containing plains, canyons, active and extinct volcanoes, mountain ranges, and hot springs. Bathymetry is the study of the "beds" or "floors" of water bodies, including the ocean, rivers, streams, and lakes. Information and data for those studies is on the USGS Maps of America's Submerged Lands website.

( Click the thumbnail to play the animation. The Northern Sea Route is a similar route that connects the Atlantic Ocean to the Pacific Ocean across the northern coast of the Eurasian Continent. At the Mid Atlantic Ridge, and in particular around the islands of the Azores, currents, water masses and species of different biogeographic origin meet and mix - shallow seamounts often acting as stepping stones for cross-Atlantic dispersal of species, including wide-ranging migratory species. 15 oceanexplorer.noaa.gov Learning Ocean Science through Ocean Exploration Section 2: Mapping the Ocean Floor: Bathymetry 15 • An Ocean of Weather in Islands in the Stream 2002 • Finding the Way from Deep East 2001 • At the Edge of the Continent in Islands in the Stream 2002 • Mapping Seamounts in the Gulf of Alaska from Exploring Alaska’s Seamounts 2002 The North Atlantic Hurricane Models have been well-validated by over 20,000 wind and storm surge observations, over $300 billion in industry loss data, and more than $20 billion of location-level claims and exposure data (including Hurricanes Katrina, Ike, and Sandy) spanning more than 25 years.

Up to date, bottom topography of the abyssal ocean plains and deep-sea channels and passages controlling the deep water exchange between the ocean basins in the East Atlantic is still poorly studied. The term "bathymetry" originally referred to the ocean's depth relative to sea level, although it has come to mean “submarine topography,” or the depths and shapes of underwater terrain. Imaging of the U.S. Atlantic East Coast was completed in 1987. The Norwegian trench was formed during the Pleistocene by fluvial erosion and by glaciers and ice sheets moving toward the Atlantic Ocean. Would the floor of the North Atlantic's be better described as mostly an "innie" or an "outie"?
