Effect of U.V. Light on Bacterial Growth Rates in Lakes and Ponds in the Canadian High Arctic
Principal Investigator: Howard, Susan
Licenced Year(s): 1993 1992
Summary: The researcher will relate a survey of the absorbence characteristics of DOC in lakes and ponds at two latitudes in the NWT to bacterial growth rates. Water samples will be collected and bacterial growth rates estimated using the tritiated thymidine method. Samples will be incubated in quartz tubes at various depths in the water column to determine the effect of in situ exposure to U.V. radiation...
