Résumé:
This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. Because river flows are s...
