An open ocean record of the Toarcian oceanic anoxic event     ocean record  Toarcian oceanic anoxic event       font style='font-size:12px;'> 2014/12/31
Oceanic anoxic events were time intervals in the Mesozoic characterized by widespread distribution of marine organic matter-rich sediments (black shales) and significant perturbations in the global ca...
Lake St. Croix is a natural impoundment located at the southern end of the St. Croix River. Land use changes since European settlement (c. 1850) have resulted in nutrient runoff, eutrophication, and p...
The Lower Mystic Lake (Medford/Arlington, MA) is a 24 m deep, ectogenically meromictic, low elevation (1 m a.s.l.), coastal lake directly connected to Boston Harbor by the Mystic River. About 1,000 ye...
The Cenomanian/Turonian (C/T) boundary marine strata of the Late Cretaceous Western Interior Sea (WIS) exhibit a positive carbon isotopic excursion in the bulk-carbonate and organic carbon. This marks...
The temperature-sensitive lipids, long chain alkenones (LCAs), are considered to be a powerful paleothermometer in deciphering the variability of sea surface temperature (SST) through time. Recent stu...
This thesis presents a multi-proxy paleoenvironmental reconstruction from the sedimentary archives of Lilandsvatnet, a small arctic lake on Vestvågøy, in the Lofoten Islands, Norway. Lofoten...
Arctic climate variability over the Holocene has been both extensive and, at times, abrupt. Current understanding of these changes is still quite limited with few highresolution paleoclimate records a...
Lake St. Croix is a natural impoundment located at the southern end of the St. Croix River. Land use changes since European settlement (c. 1850) have resulted in nutrient runoff, eutrophication, and p...

The following is part sixteen in a series on the National Science Foundation's Long-Term Ecological Research (LTER) Network. Visit parts one, two, three, four, five, six, seven, eight, nine, ten, elev...
RENO – A team of scientists led by Michael Sigl and Joe McConnell of Nevada’s Desert Research Institute (DRI) have completed the most accurate and precise reconstruction to date of historic volcanic s...
Sedimentary rocks are the archives of environmental conditions and ancient planetary surface processes that led to their formation. Reconstructions of Earth’s past surface behaviour from the physical ...
Congratulations! In arriving at the Mineralogical Record website you have made a connection with people who love minerals as much as you do, whether you are a beginner or an advanced mineral collector...
When it comes to amphibian and reptile biodiversity, the eastern slopes of the Andes Mountains in South America stand out. A new survey of "herps" in and around Manu National Park in Peru by the Unive...
Soil production breaks geologic speed record(图)     Soil production  rock       font style='font-size:12px;'> 2014/3/17
Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand shows that rock can transform into soil more than twice as fast as previously believed possible. ...
The Earth's atmospheric concentration of carbon dioxide (CO2) is about to rise to 400 parts per million (ppm) for the first time in five million years, a scientist at The University of Queensland warn...
