SUBJECT: #19 Improving Fish Monitoring
SYNOPSIS: Monitoring water quality downstream of pulp mills is supposed to protect the aquatic environment and its inhabitants. However, the testing done on fish to analyze contaminants kills far more fish than any effluent ever has. Expanding on his graduate work looking at sentinel species of fish as environmental indicators, aquatic biologist Mark Spafford is championing an alternative form of monitoring that focuses on the entire fish community, rather than one or two "sentinel" species, which does not require the massive killing of fish to gather pertinent data

SUBJECT: #19 Mars Trip
SYNOPSIS: Dr. Andrew Yau has designed a Thermal Plasma Analyzer, an instrument the size of a coffee cup, which is presently on its way to Mars on the Nuzomi satellite launched by the Japanese in 1998. It originally was to orbit Mars in 1999, but went off course. And now is expected to arrive in January 2004. Dr. Yau is interested in process by which Mars lost its water. A previous "successful" Mars mission by the Americans showed to everyone's surprise that Mars is losing its magnetic field, with the force varying wildly around the planet. Unlike Earth's strong and relatively even magnetosphere which protects the planet from plasma particles in the solar wind, Mars is bombarded and these penetrate the atmosphere, gradually ripping away the atmosphere, and along with it, its water. So the theory goes. Check out the Nuzomi animation at www.phys.ucalgary.ca.

SUBJECT: #19 The Life and Work of Dr. William Rowan
SYNOPSIS: As curator of the zoology museum at the University of Alberta, Wayne Roberts owes his present day position to a pioneer zoologist, Dr. William Rowan. Rowan came to Alberta in 1908 and set up the Zoology Department at the U of A in 1920, and soon after established the beginnings of a museum with specimens he collected himself. Rowan was a man of many talents, an artist, musician, and scientist. His love of birds in particular made him famous around the world in the 1920's and 1930's with his groundbreaking research on the factors that cause bird migration. He illustrated his scientific publications with his own lifelike drawings of the wildlife he studied.
