Natural Gas Resources of the Greater Green River and Wind River Basins of Wyoming (Assessing the Technology Needs of Sub-economic Resources, Phase I: Greater Green River and Wind river Basins, Fall 2002)

In 2000, NETL conducted a review of the adequacy of the resource characterization databases used in its Gas Systems Analysis Model (GSAM). This review indicated that the most striking deficiency in GSAM’s databases was the poor representation of the vast resource believed to exist in low-permeability sandstone accumulations in western U.S. basins. The model’s databases, which are built primarily around the United States Geological Survey (USGS) 1995 National Assessment (for undiscovered resources), reflected an estimate of the original-gas-inplace (OGIP) only in accumulations designated “technically-recoverable” by the USGS –roughly 3% to 4% of the total estimated OGIP of the region. As these vast remaining resources are a prime target of NETL programs, NETL immediately launched an effort to upgrade its resource characterizations. Upon review of existing data, NETL concluded that no existing data were appropriate sources for its modeling needs, and a decision was made to conduct new, detailed log-based, gas-in-place assessments

New light on the origins of the Ottawa Field-Naturalists’ Club

The history of the Ottawa Field-Naturalists’ Club (OFNC) is a subject of considerable interest given the organization’s great longevity and significant influence on the evolution of Canadian science and conservation. A probe of 19th-century Ottawa newspapers has led to the proper identification of a little known precursor organization — the “Ottawa Naturalists’ Field Club” — that appears to have significantly strengthened a weak link in the otherwise unbroken chain of natural history investigation in Ottawa reaching back to the pre-Confederation era. This and additional findings suggest that Dr. Edward Van Cortlandt, while duly recognized as an important pioneer naturalist, played an even greater role than generally understood in the emergence of a robust natural history tradition in Canada’s capital and the eventual creation of the OFNC

Cholera, the “sawdust menace,” and the river doctor: How fear of an epidemic triggered Canada’s first “pollution” controversy

A probe of nineteenth-century newspapers and other sources has revealed that it was an effort to prevent a cholera epidemic in the Province of Canada in 1866 that sparked a landmark controversy over sawdust dumping in the Ottawa River, Canada’s first major battle over industrial pollution. Ottawa’s newly appointed medical officer of health, Dr. Edward Van Cortlandt, was a leading figure that year in shaping both the city’s and the colony’s strategies to combat a feared cholera outbreak when he sounded alarms about the harmful impacts on fish, navigation, and human health of sawdust waste emanating from the famous Chaudière Falls lumber mills just upstream from Parliament Hill. This previously unidentified trigger to the “sawdust question”-the only explicitly “environmental” issue raised during the Confederation debates as well as the start of a 40-year struggle over sawmill “offal” in the Ottawa and across the country-represents an important intersection in the early h

How pigs\u27 blood could save lives: Canadian study could end need for human donations

Dr. [Vivian McAlister] agrees that the risk of inter-species infection remains a key obstacle to producing safe pigblood products for people: The most important thing is that the safety of this sort of thing has to be thoroughly assessed before any implementation. We\u27re dealing more with the immunological barriers, not the infectious disease, he says of his research. However, if the infectious risks were overcome, or they were understood, an animal source for blood donation could revolutionize blood-supply services around the world, he says. Currently mired in a depressed pork market that is threatening to put many producers out of business, the industry has recognized the rich humanitarian and economic prospects of animal-to-human transplants: As well as a rich source of nutrition, pigs may soon provide mankind with the most precious gift of all: life, said a recent issue of Pork Producer, the trade journal of the Ontario pork industry, citing Dr. McAlister\u27s research. Research into using animal blood in humans -- including ill- fated tranfusions in earlier times -- has been going on since the 17th century. Blood from any animal besides large primates was always attacked and its red cells destroyed by human antibodies. But in 1988, the major difference between human blood and that of other mammals was learned to be the sugar alpha gal, which Dr. McAlister\u27s team says it can now treat
