Geophysical Research Letters is a semi-monthly peer reviewed scientific journal published by the American Geophysical Union that was established in 1974. The editor-in-chief is Eric Calais (Purdue University). The stated purpose of Geophysical Research Letters is rapid publication of conscise research reports that may significantly influence one or more American Geophysical Union disciplines. These particular geoscience disciplines are atmospheric sciences, solid earth, space sciences, ocean sciences, hydrology, land surface processes, and the cryosphere. GRL also publishes twelve invited reviews that cover advances achieved during the past two or three years. The target readership is the earth science community, the broader scientific community, and the general public. This journal is indexed in the following databases: According to the Journal Citation Reports, the journal has a 2010 impact factor of 3.505, ranking it 12th out of 165 journals in the category "Geosciences, Multidisciplinary". Geophysical Research Letters was also the 5th most cited publication on climate change between 1999 and 2009.
Massive amounts of Saharan dust fertilize the Amazon rainforest
The Sahara Desert and the Amazon rainforest seem to inhabit separate worlds. The former is a vast expanse of sand and scrub stretching across the northern third of Africa, while the latter is a dense green mass of humid jungle ...
Evolution of the Antarctic ice sheet
ULB study sheds a new light on the stability of the Antarctic ice sheet. It shows for the first time that ice rises (pinning points that keep the floating parts of ice sheets in place) are formed during the transition between ...
Amazon rainforest losses impact on climate change, study shows
Human activity has removed more than one-tenth of trees and plants from the Amazon rainforest since the 1960s, a study shows.
Bubbles from glacier ice turn up the noise in Alaska fjords
Glaciologist Erin Pettit began a research project to find out what humpback whales heard when a big piece of ice falls from a glacier and crashes into the ocean. But the sound generated by ice drifting in the water turned ...
Seafloor volcano pulses may alter climate
Vast ranges of volcanoes hidden under the oceans are presumed by scientists to be the gentle giants of the planet, oozing lava at slow, steady rates along mid-ocean ridges. But a new study shows that they flare up on strikingly ...
The two faces of Mars
A moon-sized celestial object that crashed into the south pole: ETH researchers use a simulation to demonstrate why Mars consists of two notably different hemispheres.
Rivers might constitute just 20 percent of continental water flowing into oceans
If you think rivers are what send terrestrial rainfall back into the oceans, you don't know the half of it. And that fraction keeps shrinking. According to new research, it might be that only one-fifth of the water flowing ...
Iceland rises as its glaciers melt from climate change
The Earth's crust under Iceland is rebounding as global warming melts the island's great ice caps, a University of Arizona-led team reports in an upcoming issue of Geophysical Research Letters.
Typhoon Haiyan's storm surge may contaminate aquifer for years
In research of significance to the world's expanding coastal populations, scientists have found that geology and infrastructure play key roles in determining whether aquifers that provide drinking water are inundated with ...
Small volcanic eruptions partly explain 'warming hiatus'
The "warming hiatus" that has occurred over the last 15 years has been partly caused by small volcanic eruptions.
