While global-warming-induced coastal flooding moves populations inland, the changes in sea level will affect the salinity of estuaries, which influences aquatic life, fishing and recreation.Researchers from Penn State and the University of Maryland Center for Environmental Science are studying the Chesapeake Bay to see how changes in sea level may have affected the salinity of various parts of the estuary."Many have hypothesized that sea-level rise will lead to an increase in estuarine...

Observations from satellites now allow scientists to monitor changes to water levels in the sea, in rivers and lakes, in ice sheets and even under the ground. As the climate changes, this information will be crucial for monitoring its effects and predicting future impacts in different regions. Sea level rise in one of the major consequences of global warming, but it is much more difficult to model and predict than temperature. It involves the oceans and their interaction with the atmosphere,...

A NASA-led research team has used satellite data to make the most precise measurements to date of changes in the mass of mountain glaciers in the Gulf of Alaska, a region expected to be a significant contributor to global sea level rise over the next 50-100 years. Geophysicist Scott Luthcke of NASA's Goddard Space Flight Center, Greenbelt, Md., and colleagues knew from well-documented research that changes in the cryosphere -- glaciers, ice caps, and other parts of the globe covered...

The Greenland ice cap has been a focal point of recent climate change research because it is much more exposed to immediate global warming than the larger Antarctic ice sheet. Yet while the southern Greenland ice cap has been melting, it is still not clear how much this is contributing to rising sea levels, and much further research is needed. A framework for such research was defined at a recent workshop organized by the European Science Foundation (ESF). "The main objectives were to...

As the world looks for more energy, the oil industry will need more refined tools for discoveries in places where searches have never before taken place, geologists say. One such tool is a new sediment curve (which shows where sediment-on-the-move is deposited), derived from sediments of the Paleozoic Era 542 to 251 million years ago, scientists report in this week's issue of the journal Science. The sediment curve covers the entire Paleozoic Era. "The new Paleozoic sea-level sediment curve...

Researchers from TU Delft joined forces with the Center for Space Research (CSR) in Austin, Texas, USA, to develop a method for creating an accurate picture of Greenland's shrinking ice cap. On the strength of this method, it is now estimated that Greenland is accountable for a half millimeter-rise in the global sea level per year. These findings will be published in the scientific journal Geophysical Research Letters in early October. The research was based on data from the German-American...

By Richard Sadler New research by the Met Office has revealed that official predictions for sea level rise are out of date because they do not include the effects of melt water from the massive Greenland ice sheet.The situation is so serious that the Environment Agency is being forced to review its flood defence plans for London. Contingency plans for other major low-lying cities Hull, Newcastle, Glasgow and Norwich will also have to be re-evaluated.The extent of the problem was revealed...

By Mark Summers The Farne Islands have been identified as being among ten coastal landmarks owned by the National Trust which could suffer because of erosion and rising sea levels. The 30 islands, which are two miles off the coast of Northumberland, are a popular tourist attraction and are internationally important for wildlife. Twenty species of seabirds breed there, including 55,674 pairs of puffins, and a colony of grey seals uses the islands as pupping grounds. But a report for the...

Less than a month after launch, the NASA-French space agency Ocean Surface Topography Mission (OSTM)/Jason 2 oceanography satellite has produced its first complete maps of global ocean surface topography, surface wave height and wind speed. The new data will help scientists monitor changes in global sea level and the distribution of heat in the ocean. This information is used to monitor climate change and ocean circulation, and to enable more accurate weather, ocean and climate forecasts. The...

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...
