A map shows the minimum sea ice extent and glacial loss (2010 to 2020), marked by blue circles. The largest glacial loss is in the Gulf of Alaska, 83.1 gigatons, and the smallest in Iceland, Antarctic, and Subantarctic, 3.5 gigatons.

Loss of glacial ice between 1961 and 2016 measured using satellite imagery and field observations.

A map shows ocean climate zones with different colors indicating Equatorial, Tropical, Subtropical, Temperate, Subpolar, and Polar zones.&nbsp;

Ocean Climate Zones

The map illustrates the various ocean climate zones around the globe:Equatorial Zone: Located around the equator, covering regions like the central Pacific Ocean, the equatorial Atlantic Ocean, and parts of the Indian Ocean near the equator.Tropical Zone: Found just north and south of the equatorial zones, covering areas like the northern Indian Ocean, parts of the Atlantic Ocean near the equator, and the central Pacific Ocean.Subtropical Zone: Located further from the equator, covering areas like the southern parts of the North Atlantic and North Pacific Oceans, northern parts of the South Atlantic and South Pacific Oceans, and parts of the Indian Ocean.Temperate Zone: Found in mid-latitude regions, covering areas like the North Atlantic Ocean off the coast of Europe and North America, the North Pacific Ocean off the coast of North America, and the Southern Ocean surrounding Antarctica.Subpolar Zone: Located in higher latitude regions, covering areas like the North Atlantic Ocean near Greenland, the North Pacific Ocean near Alaska, and parts of the Southern Ocean.Polar Zone: Found in the polar regions, covering areas like the Arctic Ocean and the Antarctic region.Warm Currents: Include currents such as the Gulf Stream in the North Atlantic Ocean, the Kuroshio Current in the North Pacific Ocean, and the Brazil Current in the South Atlantic Ocean.

A map illustrates the different depth zones of the coastal areas. The shallowest areas (light blue), are near the coasts, such as the eastern United States and Europe. The deepest regions (dark blue), are in the Pacific and Atlantic Oceans.

Ocean Bathymetry

Shallow ocean areas near continents' coastlines range from sea level to negative 200 meters and are shaded in light yellow. Continental shelves and upper slopes, shaded in yellow, are found between negative 201 to negative 2,000 meters. Mid-ocean depths, including parts of the abyssal plains, range from negative 2,000 to negative 3,000 meters and are shaded in orange. Deeper ocean areas, extending further into the abyssal plains, range from negative 3,000 to negative 4,000 meters in dark orange. Deep ocean regions, covering significant portions of the ocean floor, range from negative 4,000 to negative 5,000 meters in dark brown. Very deep ocean trenches and basins are found between negative 5,000 to negative 6,000 meters and are shaded in blue. The deepest parts of the ocean, including the Mariana Trench and other deep-sea trenches, are below negative 6,000 meters and are represented in dark blue.
