Jurassic Records Warn Of Risk From Global Warming On Marine Life
2013-02-19 14:08:45

Plymouth University Researchers at Plymouth University, UK, believe that findings from fieldwork along the North Yorkshire coast reveal strong parallels between the Early Jurassic era of 180 million years ago and current climate predictions over the next century. Through geology and palaeontology, they've shown how higher temperatures and lower oxygen levels caused drastic changes to marine communities, and that while the Jurassic seas eventually recovered from the effects of global...

Mapping Forest Biomass To Understand The Global Carbon Cycle
2013-02-05 10:54:59

ESA Satellite radar data are being used to map Earth´s vital resources. The latest advances and applications of the POLinSAR remote sensing technique were highlighted at a conference held last week. Polarimetric InSAR — or POLinSAR — is a remote sensing technique based on polarimetric information in Synthetic Aperture Radar (SAR) images. With this technique, a radar sends polarised pulses towards the target, and the information in the signals backscattered from Earth...

Jurassic Ecosystem
2013-01-09 06:26:57

Rayshell Clapper for redOrbit.com - Your Universe Online According to Southern Methodist University paleontologists Timothy S. Myers, Louis L. Jacobs, and SMU sedimentary geologist Neil J. Tabor, the modern relationship between animals and vegetation is similar to millions of years ago. In their study, the SMU scientists used fossil soils from the Late Jurassic age gathered from locations where animal fossils were previously found to determine the levels of carbon isotopes. The team...

Berkeley Lab research could lead to a better understanding of the Arctic ecosystem´s impact on the planet's climate What does pulling a radar-equipped sled across the Arctic tundra have to do with improving our understanding of climate change? It´s part of a new way to explore the little-known world of permafrost soils, which store almost as much carbon as the rest of the world´s soils and about twice as much as is in the atmosphere. The new approach combines several...

Ediacaran Fossils A 'First-class Scientific Mystery'
2012-12-13 08:50:07

redOrbit Staff & Wire Reports - Your Universe Online Mysterious multicellular fossils believed to be ancient sea creatures may actually be some of the earliest land-dwelling organisms, according to a paper published online on Wednesday in the journal Nature. The controversial hypothesis has been fiercely criticized, with some paleontologists flatly rejecting the idea, but if true, the finding would push back life's transition from sea to land by as much as 100 million years or more....

New Test Helps With Understanding Earth’s History And Resources
2012-12-06 10:18:32

University of Florida A new study co-authored by a University of Florida researcher provides the first direct chronological test of sequence stratigraphy, a powerful tool for exploring Earth´s natural resources. The model allows geologists to better understand how sedimentary rocks are related to one another in time and space and predict what types of rocks are located in different areas. The information may help scientists more reliably interpret various aspects of Earth´s...

Anthropocene Continues To Instigate Scientific Debate
2012-11-01 13:07:36

Geological Society of America GSA Annual Meeting Technical Session: "Geomorphology of the Anthropocene" How have humans influenced Earth? Can geoscientists measure when human impacts began overtaking those of Earth's other inhabitants and that of the natural Earth system? Responding to increasing scientific recognition that humans have become the foremost agent of change at Earth's surface, organizers of this GSA technical session have brought together speakers and poster presentations...

Earth Science Week 2012
2012-10-14 05:13:30

April Flowers for redOrbit.com - Your Universe Online October 14 — 20, 2012 is Earth Science Week, a celebration designed to encourage people everywhere to learn more about the geosciences and explore the natural world. The organizers also hope to foster a feeling of responsibility for Earth stewardship. Earth Science Week was first organized in 1998 by the American Geological Institute (AGI). Every year since then, events are planned by community groups, educators and interested...

April Flowers for redOrbit.com - Your Universe Online October 17, 2012 is National Fossil Day, sponsored by the National Park Service (NPS) and the American Geological Institute (AGI). This year is the third annual event, scheduled in conjunction with Earth Science Week. The mission of National Fossil Day is to promote public awareness and stewardship of fossils. The NPS hopes to foster an appreciation of the scientific and educational value of fossil preservation and study. "Fossils...

Evolution Of Complex Brains
2012-10-11 04:52:39

April Flowers for redOrbit.com - Your Universe Online Anatomically complex brains evolved earlier than previously thought and have changed little over the course of time, according to a new study by University of Arizona neurobiologist Nicholas Strausfeld. The specimen described in the study, which will be published in the October 11 issue of Nature, is the earliest known fossil to show a brain. The three inch long fossil was discovered embedded in mudstones deposited during the...

Environmental Science
2014-01-12 00:00:00

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,...
