Ancient Antarctic Ice Melt 66 Feet
2013-07-22 08:50:47

Brett Smith for redOrbit.com - Your Universe Online A large team of international researchers has looked millions of years into the Antarctic past and found evidence that massive sections of the continent's eastern ice sheet once melted to raise sea levels by around 66 feet. "Scientists previously considered the East Antarctic ice sheet to be more stable than the much smaller ice sheets in West Antarctica and Greenland, even though very few studies of East Antarctic ice...

Rising Sea Levels Will Require Adaptation For Generations To Come
2013-07-17 05:46:24

Susan Bowen for redOrbit.com - Your Universe Online Current levels of greenhouse gas emissions will have far-reaching effects, even if the levels decrease in the near future. According to a new study published in the Proceedings of the National Academy of Sciences, the greenhouse gases emitted today will cause the sea level to rise for centuries to come. It is estimated each degree of global warming will raise sea levels by more than two meters. Anders Levermann, lead author of the...

Satellite Data Not Enough Predict Ice Cap Melt
2013-07-15 09:38:00

Brett Smith for redOrbit.com - Your Universe Online New research from a team of European scientists has found there is not enough satellite data to determine the rate of polar ice cap melt very far into the future and warned against using current trends to predict sea level rise that might result from melting glaciers. The ice sheets on Greenland and Antarctica represent the biggest potential contributor to sea level rise. According to a study published last year including data from...

Surface Melt Will Continue To Dominate Greenland Ice-Loss
2013-07-10 15:13:45

Lee Rannals for redOrbit.com - Your Universe Online According to research published in the Journal of Glaciology, surface ice melt will be the dominant process controlling ice-loss from Greenland. Greenland's ice sheet is considered an important potential contributor to future global sea-level rise over the next century or longer. It contains an amount of ice that could lead to a rise of global sea-level by more than 22 feet if it completely melted. Changes in its total mass are caused...

Upwellings In Earth's Mantle Have Remained Stable Over Geologic Time
2013-06-27 08:33:06

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Hawaii - Manoa's School of Ocean and Earth Science and Technology (SOEST) reveals that the large-scale upwelling within Earth's mantle mostly occur in only two locations: beneath Africa and the Central Pacific. Clinton Conrad, associate professor of geology at SOEST, led the team of researchers who found, despite dramatic reconfigurations of tectonic plate motions and continental locations on the...

New Report Says Sea Level Along Maryland's Shorelines Could Rise Two Feet By 2050
2013-06-26 14:47:56

University of Maryland Center for Environmental Science A new report on sea level rise recommends that the State of Maryland should plan for a rise in sea level of as much as 2 feet by 2050. Led by the University of Maryland Center for Environmental Science, the report was prepared by a panel of scientific experts in response to Governor Martin O'Malley's Executive Order on Climate Change and "Coast Smart" Construction. The projections are based on an assessment of the latest climate...

Researchers Map New Jersey Sea-Level Changes Over Last 10,000 Years
2013-05-29 09:07:40

April Flowers for redOrbit.com - Your Universe Online The public and policymakers alike were caught off guard when Hurricane Sandy hit the east coast of the US last fall. The majority of the destruction came from the storm surge and flooding that followed the storm, leading researchers to pay attention to how climate change and sea-level rise may have played a role in the disaster, and how those same factors may impact the shoreline in the future. Benjamin P. Horton, an associate...

Alaska´s melting glaciers remain one of the largest contributors to the world´s rising sea levels, say two University of Alaska Fairbanks geophysicists. UAF Geophysical Institute researchers Anthony Arendt and Regine Hock joined 14 scientists from 10 countries who combined data from field measurements and satellites to get the most complete global picture to date of glacier mass losses and their contribution to rising sea levels. “Sea level change is a pressing societal...

Earth’s Ice Sheets More Stable Than Once Thought
2013-05-17 10:44:21

April Flowers for redOrbit.com - Your Universe Online For decades, researchers have used ancient shorelines to predict the stability of today´s largest ice sheets in Greenland and Antarctica. High shoreline markings from three million years ago as Earth was going through a warm period were thought to be evidence of a high sea level due to ice sheet collapse at the time — an assumption that has led many scientists to believe that if the world´s largest ice sheets collapsed...

Current Sea Level Rise
2013-04-01 10:39:21

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
