In the first study of its kind, the American Geosciences Institute (AGI) Workforce Program has published the results of the National Geoscience Student Exit Survey, which documents the experiences of graduating geosciences majors. Initial findings support that these new graduates, at all levels, shared some common traits such as the importance of field experiences and exposure to Earth science at the K-12 level. The need for continued growth in the geoscience workforce is well documented...

2013-09-23 07:44:57

[ Watch The Video: 2013 Arctic Sea Ice Minimum Animation ] NASA After an unusually cold summer in the northernmost latitudes, Arctic sea ice appears to have reached its annual minimum summer extent for 2013 on Sept. 13, the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado in Boulder has reported. Analysis of satellite data by NSIDC and NASA showed that the sea ice extent shrunk to 1.97 million square miles (5.10 million square kilometers). This...

No Single Factor Behind Cambrian Explosion Of Animal Life
2013-09-20 07:58:01

April Flowers for redOrbit.com - Your Universe Online A new study from the UK reveals that the explosion of animal life on Earth that occurred around 520 million years ago was the result of a combination of interlinked factors, rather than a single underlying cause. Over the past few decades, dozens of individual theories have been put forth for the rapid diversification of animal species in the early Cambrian period. The new study, published in Science, suggests a more holistic...

Lee Rannals for redOrbit.com - Your Universe Online Scientists publishing a study in the journal African Invertebrate say they have discovered a 350-million-year-old fossilized scorpion. The specimen, discovered in rocks from the Devonian Witteberg Group near Grahamstown, is a new species of scorpion called Gondwanascorpio emzantsiensis. Dr Robert Gess, from the Evolutionary Studies Institute at Wits University, discovered the specimen, which is said to be the oldest known land-living...

Land Life Earlier Than Thought
2013-07-22 14:37:42

Brett Smith for redOrbit.com - Your Universe Online Conventional theories have placed life on land for the last 500 million years, but a new study from a team of American and Australian researchers might push that back to 2.2 billion years. To support their claim, the scientists presented evidence in the form of tiny newly discovered fossils the size of a match head called Diskagma buttonii that were discovered in ancient soil samples. "They certainly were...

Community colleges provide a strong foundation for the nation's graduating STEM (Science Technology Engineering and Mathematics) workforce. In its latest Geoscience Currents, the American Geosciences Institute documents the flow of geoscience students from 2–year to 4-year institutions in Texas, adding to an earlier report on similar data from California released in 2012. In 2012, 70 percent of geoscience students in Texas public universities had transferred from...

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...

Earth science (or geoscience) is the science of the planet Earth. Earth science can be broken down into four major disciplines, which are: geography, geology, geophysics, and geodesy. These disciplines use physics, chemistry, biology, chronology and mathematics to arrive to a greater understanding of the principal areas of the Earth system. Since Earth is the only known life-bearing planet, Earth science is solely dedicated to the geophysical makeup of our own planet. One discipline,...
