Objective(s): To obtain preliminary data on bacterial growth rates in lakes and ponds at two different latitudes in the High Arctic; to relate bacterial growth rates in the water column to the dissolved organic carbon (DOC) concentration; to determine whether bacterial growth rates are adversely affected by increased exposure to U.V. radiation;
Project Description: 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. Sub-samples will be preserved for later bacterial counts.
