Objective(s): To obtain preliminary data on bacterial growth rates in lakes and ponds 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 UV radiation.
Project Description: Ozone depletion in the High Arctic could result in exposure of aquatic organisms (such as bacteria) to higher levels of ultraviolet (UV) radiation from the sun. This increased exposure to radiation may be harmful to bacteria and have an effect on organisms which feed on bacteria. I will collect water samples from lakes and ponds in the Resolute area in order to measure bacterial growth rates as well as the response of bacteria to known levels of UV radiation.
