Latest Sea level Stories
The cause of rapid sea level rise in the past has been found by scientists at the University of Bristol using climate and ice sheet models.
First analyses of the longest sediment core ever collected on land in the terrestrial Arctic provide documentation that intense warm intervals, warmer than scientists thought possible, occurred there over the past 2.8 million years
The sea level of the eastern coast of the United States is accelerating at a much faster rate than the country's other coasts due to global warming, claim researchers from the U.S. Geological Survey (USGS).
The sea level of the US West Coast is expected to increase 60 centimeters from Washington to northern California, while waters surrounding the southern half of that state could rise a meter in less than two decades time.
Researchers from Denmark’s University of Copenhagen have gained new insight into the loss of ice mass in Greenland’s glaciers thanks to a chance discovery of 80-year-old photo plates discovered in a Danish basement.
CryoSat was launched in 2010 to measure sea-ice thickness in the Arctic, but data from the Earth-observing satellite have also been exploited for other studies.
It was used to help Apollo astronauts navigate in space, and has since been applied to problems as diverse as economics and weather forecasting, but Harvard scientists are now using a powerful statistical tool to not only track sea level rise over time, but to determine where the water causing the rise is coming from.
As people pump groundwater for irrigation, drinking water, and industrial uses, the water doesn’t just seep back into the ground — it also evaporates into the atmosphere, or runs off into rivers and canals, eventually emptying into the world’s oceans.
Some of Greenland's glaciers are moving approximately 30% faster than they were a decade ago, contributing to the rising sea level but not reaching worst-case speed levels that experts once feared.
An international team of scientists reported in the journal Nature on Thursday that warm ocean currents are the culprit behind recent ice loss in Antarctica.
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...
