Latest Sea level Stories
A higher-than-normal 2010 melting season sped up the melting of ice in southern Greenland, causing sizable portions of the island's bedrock to rise somewhere about a quarter of an inch more than usual.
The Greenland ice sheet can experience extreme melting even when temperatures don’t hit record highs, according to a new analysis.
New evidence of sea-level oscillations during a warm period that started about 125,000 years ago raises the possibility of a similar scenario if the planet continues its more recent warming trend.
Like mercury in a thermometer, ocean waters expand as they warm.
WASHINGTON, Aug. 18, 2011 /PRNewswire-USNewswire/ -- NASA-funded researchers have created the first complete map of the speed and direction of ice flow in Antarctica.
An analysis of prehistoric "Heinrich events" that happened many thousands of years ago, creating mass discharges of icebergs into the North Atlantic Ocean, make it clear that very small amounts of subsurface warming of water can trigger a rapid collapse of ice shelves.
During the last prolonged warm spell on Earth, the oceans were at least 20 feet higher than they are now.
GREENBELT, Md., July 25, 2011 /PRNewswire-USNewswire/ -- An international team of researchers has combined data from multiple sources to provide the clearest account yet of how much glacial ice surges into the sea following the collapse of Antarctic ice shelves.

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found.
Study on Jakobshavn Isbrae supports growing evidence that calving glaciers are particularly sensitive to climate change.
The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...
A radar altimeter measures altitude above the terrain beneath an aircraft as opposed to a barometric altimeter which provides the distance above a pre-determined datum, usually sea level. Radar is the underpinning principle of the system. Radio waves that are reflected back from the ground are timed in order to calculate speed, distance, and time which are related to the each other and can be used to calculate the distance from one point to another. Lloyd Espenschied invented the radar...
