Sulphur And Iron Haunts The Ghost Wreck
2014-03-05 11:01:04

Carina Eliasson, University of Gothenburg Sulphur and iron accumulation has once again been found in wood samples from old shipwrecks in the Baltic Sea. This time the samples are from the merchant vessel Ghost wreck and the warships Sword and the Crown. Wood samples from the ships have been analyzed by a group of scientists from the University of Gothenburg, Stockholm University and University of Calgary. The results are published in the latest issue of Scientific Reports. Scientists...

Researchers Have Developed New Quantitative Method Of Identifying Pollen Grains
2013-10-07 13:10:51

University of Illinois Since the invention of the earliest light microscopes, the classification and identification of pollen and spores has been a highly subjective venture for those who use these tiny particles to study vegetation in their field, palynology. However, according to the lead author of the study, Luke Mander, a former postdoctoral researcher in the laboratory of Illinois professor of plant biology Surangi Punyasena, the limitations imposed by these descriptive rather than...

Researchers Use Poop To Track Prehistoric Humans
2012-11-27 11:55:50

April Flowers for redOrbit.com - Your Universe Online Disentangling the effects of climate change from those related to human activities is a major challenge for scientists who study the Earth's environmental history. Researchers from the University of Massachusetts, Amherst have recently gotten creative with poop, using a special biomarker found in human feces to establish the first human presence, the appearance of grazing animals and human population dynamics in a landscape. "We are...

Tree Rings Tell The Tale Of Drought History
2012-07-03 11:58:11

Pitt scientists also discover unexpected complexity to the US West's patterns of drought during the Middle Ages Through an exploration of tree rings and oxygen isotopes, researchers at the University of Pittsburgh are now able to better pinpoint the history of droughts in the arid and semiarid areas of the American West. A paper published in the online July 2 issue of the Proceedings of the National Academy of Sciences explores the Medieval Climate Anomaly, a particularly warm period...

The National Science Foundation has funded a study to determine past climates by studying tree rings. Environmental students from Arizona studied bristlecone pine trees to determine aspects about the Earth´s climates during the Paleo age. The study of tree growth rings to understand Earth´s past climate is called dendrochronology. As each year passes, trees add growth rings around their trunks. These dendrochronologists study these rings to gain all sorts of information not only...

WASHINGTON, Oct. 31, 2011 /PRNewswire-USNewswire/ -- To mark the 100th anniversary of Titanic, international experts will explore the challenges facing the world's underwater cultural heritage during a November 3 conference at the National Trust for Historic Preservation in Washington, DC. "Keeping the Lid on Davy Jones' Locker: The Protection of Underwater Cultural Heritage from Titanic to Today" will give the public an unprecedented opportunity to interact with the...

Nibbling by herbivores can have a greater impact on the width of tree rings than climate, new research has found. The study, published this week in the British Ecological Society's journal Functional Ecology, could help increase the accuracy of the tree ring record as a way of estimating past climatic conditions. Many factors in addition to climate are known to affect the tree ring record, including attack from parasites and herbivores, but determining how important these other factors have...

Analysis of direct climate record shows Antarctic tundra persisted until 12 million years ago A painstaking examination of the first direct and detailed climate record from the continental shelves surrounding Antarctica reveals that the last remnant of Antarctic vegetation existed in a tundra landscape on the continent's northern peninsula about 12 million years ago. The research, which was led by researchers at Rice University and Louisiana State University, appears online this week and will...

A group of researchers have studied the history of drought in the Pacific Northwest during the last 6,000 years, a time that spans the mid-Holocene geological epoch to the present. The goal of the research was to improve the understanding of drought history because the instrumental record of drought only goes back a few hundred years and at relatively few locations. Their work extended the drought history of the Pacific Northwest back much longer than the tree ring record, which provides...

A team of researchers conducting an extensive study of growth rings in trees say there could be a link between the rise and fall of ancient civilizations and sudden shifts in Europe's climate. They based their findings on data from more than 9,000 wooden artifacts that have come from civilizations from over the past 2,500 years, BBC News reports. In the study, published online in the journal Science, the researchers found that periods of warm, wet summers coincided with prosperity,...

Zooarchaeology
2013-09-30 13:29:48

Zooarchaeology is the study of animal remains including shells, bones, hides, scales, DNA, chitin, and hair. Shells and bones are most frequently studied because these do not decay at a fast rate, but most remains do not survive because they break or decompose. In eastern areas of North America, Zooarchaeology developed over three periods. The first, known as the Formative period, occurred in the 1860s and was not a specific area of study at that time. The second period, known as the...
