Specific activities for this field season include the following:
(1) Resolution of the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta (year 3 of PhD thesis project of S. Tank). This information is needed to ultimately understand the relative role of bacterial (fueled by DOC) versus photosynthetic organisms and their importance in ultimately sup...
