Goals of GRACE
GRACE was launched in March 2002 and has a very important mission to deliver. The information gathered from the GRACE mission will reveal the broad features of the Earth’s gravitational field overland and sea. GRACE is sensitive enough to detect small variations and produce detailed maps.
The new gravity measurements will benefit many important applications. These applications include the following:
• understanding atmosphere-ocean mass exchange;
• measuring the changing mass of polar ice caps;
• analyzing changes in water resources on land;
• determining the characteristics of both shallow and deep ocean currents;
• deciphering internal Earth forces that move tectonic plates and result in earthquakes and volcanic;
• grasping the interactions that generate Earth's geomagnetic field; and
• recognizing sea level change resulting from ocean temperature and water mass changes
It will also help to provide more accurate seasonal forecasts for the weather patterns of Earth, an improvement in forecasting of natural hazards, and an ability to track the altering distribution of water resources.
Findings of GRACE
Data from GRACE allowed scientists to conduct the first gravity survey of the entire Antarctic ice sheet. This study found the mass of the ice sheet has decreased significantly from 2002 to 2005.
Canadian and US scientists have been able to use the gravity measurements from GRACE to determine that the ancient ice sheets over Canada were made up of two major ice domes instead of one single massive dome.
Greenland has the largest reservoir of freshwater in the northern hemisphere (second largest on Earth) and any large changes in the mass of the ice sheet will impact ocean circulation, global sea level and climate. The data from GRACE shows that the melting of this ice sheet would add 0.56...
