Event Title

Seasonal Optical Properties of Chromophoric Dissolved Organic Matter (CDOM) in Surface Waters of Fresh Water Lake in Pacific Northwest

Research Mentor(s)

Catherine Clark

Description

The water of Lake Louise (a lake neighboring lake Whatcom in Whatcom County, WA) was sampled from January 17, 2018 to November 29, 2018 and absorbance and fluorescence characteristics of the water’s chromophoric dissolved organic matter were analyzed to look for seasonal trends. The majority of the parameters that were examined were determined by t-test to be statistically the same across all seasons. Some parameters, such as dissolved organic carbon (DOC) concentration, were determined by t-test to be statistically different, relative to season (winter, spring, summer, fall), but these differences were not anything abnormal. The trends that were observed logically correlated to their respective season/seasonal change. Lake Louise is a relatively typical and healthy lake, and nothing was found to be amiss.
