Geology is a publication of the Geological Society of America (GSA). The GSA claims that it is the most widely read scientific journal in the field of earth science. It is published monthly, with each issue containing 20 or more articles, and an annual total of 1166 pages. One of the goals of the journal is to provide a forum for shorter articles and less focus on pure academic research type articles.
New source of methane discovered in the Arctic Ocean
Methane, a highly effective greenhouse gas, is usually produced by decomposition of organic material, a complex process involving bacteria and microbes.
Did volcanic cataclysm 40,000 years ago trigger final demise of Neanderthals?
The Campanian Ignimbrite (CI) eruption in Italy 40,000 years ago was one of the largest volcanic cataclysms in Europe and injected a significant amount of sulfur-dioxide (SO2) into the stratosphere. Scientists have long debated ...
Radiocarbon dating reveals past fall in sea level
When carbonate samples from One Tree Reef in southern Great Barrier Reef arrived at ANSTO for radiocarbon dating, Principle Research Scientist Quan Hua was confident they could accurately determine the age of the marine material.
Humans erode soil 100 times faster than nature
A new study shows that removing native forest and starting intensive agriculture can accelerate erosion so dramatically that in a few decades as much soil is lost as would naturally occur over thousands of years.
Breakup of ancient supercontinent Pangea hints at future fate of Atlantic Ocean
Pangea, the supercontinent that contained most of the Earth's landmass until about 180 million years ago, endured an apocalyptic undoing during the Jurassic period, when the Atlantic Ocean opened up. This is well understood. ...
Large Landslides lie low: Himalaya-Karakoram ranges
Large landslides are an important process of erosion in the Himalaya-Karakoram ranges (HKR). These high-relief landscapes are characterized by steep slopes that are prone to frequent landsliding. By mapping nearly 500 large ...
Preserved tracks in Alaska park suggest duck-billed dinosaurs lived in Arctic year-round
Massive geographic change may have triggered explosion of animal life
A new analysis of geologic history may help solve the riddle of the "Cambrian explosion," the rapid diversification of animal life in the fossil record 530 million years ago that has puzzled scientists since the time of Charles ...
Revealing the real risks of a recently active volcano in southern Chile
A study by a Victoria University earth scientist has revealed the frightening potential risk posed by a recently active volcano in southern Chile, and provides insight into what could happen in New Zealand.
Engineering a better future for the Mississippi Delta
River deltas, low-lying landforms that host critical and diverse ecosystems as well as high concentrations of human population, face an uncertain future. Even as some deltas experience decreased sediment supply from damming, ...
