Southwest USA field trip 1997

Earth sciences students take part in a major field trip at the beginning of their final year. They have a choice of a field trip to Quebec or some more exotic location. Last year, 14 students opted for a two week tour of Nevada, Utah, Colorado and Arizona. Students planned each day's itinerary, contacting local experts to assist with interpretation, they were also responsible for a guidebook and an after trip presentation.

Return to Vestmannaeyjar - part II

This is the third section of a four-part article dealing with the volcanic eruptions in the Westman Islands, south of Iceland in the decade from 1963 to 1973. Part one covered the eruption of the volcano Surtsey in 1963, and my visit to the island in 1970 (WAT ON EARTH, Spring Issue 1997). Part two covered the early days of the eruption of Eldfell on Heimaey in 1973 (WAT ON EARTH, Fall issue, 1997). In this issue I will describe the continuing eruption until the cessation of activity in 1973.

Research on computer modeling of groundwater contamination

By: Dr. Edward Sudicky,
Chair, Waterloo Earth Sciences Department.

One of the difficulties in evaluating or quantifying groundwater contamination is that it is underground . . . hence, difficult and costly to get at. One way to minimize the cost would be to develop a reliable computer model that would serve as a guide, indicating what is taking place.
