The study, ilnvolving dozens of researchers from Canada' and te United States, my.eaMWird how much methane and carbon dioxide, are released and absor1bed by northem wetlands. It founid that wetland vegetation is neither os big a source of 'greenhouse gases', no as big a 'sink' (removal mechanisft for themn) as scientists originally thought. Greenhouse gases keep te eartb warn by trapping hast radiation in the atinosphere. Scientists are trYing to trace teir source, because concentrations have risen steadîly for more than 100, yeas. If trends continue, average gl obal temperatures could be substmntiâlly higher witin half a century. In the northem wetlands study, scientists from 10 Canadian universities, sevôt'l govemment Walrus near Mon treal (Continueci ftom page 8) Carolina. The Ste-Julienne walrus is not only the first record of that species from the Champlain Sea, but it fils an important gap in the ani- ma's postglacial range. Its age lies between 12,800 year-old remains from the Bay of Fundy and 7,300 year-old remains froin B3athurst Island inthe central Cana- dian Arctic Islands. This helps us to understaid better the northward ,shit of te species since te Lauren- ide ice sheet begyan its retreat.

" C.R. Harington Paleobiology Aeronautics and Space Administration (NASA), and other U. S. institutes converged onithe Hudson Bay Lowlanud, a Ihuge area encompassing mnost of northmem Manitoba and Ontario, as well as part of Quebec. Only one other -wetland area in western SiÏberia) is larger. The investigation centred prirnarily on metfhane, a gas that'sincreasing in the, atmosphere at a rate of one to two per cent a year. Before. the study, scientists had estimated the annual contribution front wetlands vegetation at about 20 per cent of total global mnethane emissions. The idea was to verif y this figure by monitoring wetlands -methane production over a long perioci of time, using a variety of different techniques. Ail the measuremnents were made during the sunimer of 1990. The researchers took readings fromntte ground, from a 20-metre tower, and fromt aircraft. Depending on ground cover, daily methane production ranged fron six to 35 milligranis per square metre. Over the whole region, that translates into between one and two billion kilogramas per year - a tremendous amnount, yet les than half of what the scientists haci expected. If this surprising finding also applies bo Russia's wetlands, then otLher methane sources are more important thani was thought, says Dr. George of land resource science at the University of Guelph. Besides wetlands, methane gas is produced by a numiber of sources related to human activities, including rice- paddies. cattie, landfills, coal nig, and oil and natural gas prodluction. The researchers had Rspected that wetlands play a relatively minor role in remnoving gree-nhouse gases from the atmosphere. According to Thurtell's colleague at Guelph, Dr. Ken King, they found that the average square metre of Lowland vegetation sucks up less than haif a gram of carbon dioxlide (C02) per day. (By comparison. foresis soalc up three grams of C02 per square metre a day, and croplands six grains.) Extrapolated over the whole riortbemn wetlands. the annual C02 uptake by wetlands is only 1/200th of the amount of C02 humnans emtit by burning fossil fuels. This study was coordinated by the Canadian Institute for Research in Aimnospheric Cbemistry. Funding was provided. by Environment Canada, the Natiiral Sciences and Engineering Research Couneil, NASA and other agencies.
