Quantitative measurements of rainfall, snowfall, the rate at which water penetrates into and moves through soil, streamflow, the rise and fall of LAKE and GROUNDWATER levels, and the evapotranspiration of water into the atmosphere are vital.
Geomatics Canada, along with the Geological Survey of Canada and the Polar Continental Shelf Project, became part of the Earth Sciences Sector of the Department of Natural Resources in the mid-1990s. It was formerly known as the Surveys, Mapping and Remote Sensing Sector.
Most modern meteorologists attempt to cope with physical processes by expressing them mathematically, ie, by creating mathematical models of the atmosphere. Powerful computers are then used to solve problems.
British ColumbiaIn BC, most work has been carried out by the Underwater Archaeological Society of British Columbia (UASBC), a large, successful and mostly avocational group that was formed in 1975. The UASBC's has published seven regional shipwreck inventories.
British Columbia's Dinosaur Excavations
In the summer of 2007 P.R.P.R.C. palaeontologists discovered a second concentration of dinosaur bones along 10 metres of exposed outcrop not far from the town of Tumbler Ridge.
Sweat lodges are heated, dome-shaped structures used by Indigenous peoples during certain purification rites and as a way to promote healthy living.
In recent years genetic diseases have become better understood since they are dependent on a fault in the normal gene sequence that controls body activities.
Bacteria are microscopic single-celled organisms capable of rapid growth and division.
In 1950, one of Canada’s greatest medical innovations was developed at the University of Toronto’s Banting Institute. Cardiac surgeon, Dr. Wilfred Bigelow and research fellow, Dr. John Carter Callaghan were trying to understand how hypothermia (see Cold-Weather Injuries) could slow the beating of an animal’s heart before surgery. They were also looking for a way to stimulate the heart when it faltered as it cooled. This largely unknown area of research could have tremendous applications for humans. The doctors partnered with Dr. Jack Hopps from the National Research Council of Canada, who created a portable artificial external pacemaker. It was designed to send electric pulses to the heart, which caused the heart to contract and pump blood to the body. The device was successfully tested on a dog in 1950. This landmark discovery paved the way for the use of implantable pacemakers in humans.
Medicare's Condition Critical
With mounting concern, Dr. Joel Carter studied the situation in the Winnipeg Health Sciences Centre emergency ward. In one resuscitation bed, an elderly heart patient lay dying, the family gathered around her.
Biochemistry, encompasses the study of the chemical nature of living material and of the chemical transformations that occur within it.
About a third of the world's estimated 400 000 species of higher or vascular plants have probably been used for medicinal purposes by indigenous societies, generally in a raw or minimally processed form.
Health Officials Divided over Avian Flu
FOR MONTHS now the warnings have been relentless: the avian flu, rampaging through Southeast Asia, could morph into some sort of monstrous microbe. Tens of millions of people could die, say the experts at no less esteemed institutions than the World Health Organization and the U.S.
Pointe-du-Buisson Archaeological Sites
Pointe-du-Buisson is a small point of land (21 ha) extending into the waters of Lake St Louis (a widening of the St-Lawrence River) at the convergence of the Ottawa River.
Canadian Aviation Disasters
There have been many tragic events in Canada’s aviation history. Some of these have involved Canadian aircraft, commercial as well as non-commercial. In other cases, many Canadians have died in the crash of a non-Canadian aircraft. Crashes that occurred over Canadian soil, or search and rescue efforts in which Canadians have played a large part, are also part of this history.

Media convergence refers to the merging of previously distinct media technologies and platforms through digitization and computer networking. This is also known as technological convergence. Media convergence is also a business strategy whereby communications companies integrate their ownership of different media properties. This is also called media consolidation, media concentration or economic convergence. (See also Media Ownership.)
One of the easiest ways to understand bitumen is to compare it to its cousin, conventional crude oil. Whereas conventional crude oil flows freely, bitumen does not. At room temperature it looks like cold molasses, and must be either heated or diluted before it flows.
