The Photochemical Evolution Of Dissolved Black Carbon In Snow: A Case Study From The North Cascades, Molly Peek

Black carbon (BC) is partially combusted organic material from natural and anthropogenic sources, and is a highly effective driver of melt in the cryosphere. BC has been found in both populated and remote areas around the globe. This study follows the evolution of UV-exposed dissolved BC (DBC) in the cryosphere using the Benzenepolycarboxylic Acid (BPCA) markers B4CA, B5CA, and B6CA. Samples were collected from Mount Baker, Washington, and from both an in situ field study and a controlled photodegradation study, both using natural and anthropogenic BC standards. Both natural and experimental samples had a dominance of B5CA relative to other …

The stability of our cryosphere relies on highly reflective snow surfaces that reflect solar radiation, thereby maintaining the energy balance of the earth. The advances in Uncrewed Aerial Vehicle (UAV) technology allow for researchers to assess snow surfaces in remote terrain at unprecedented scales. With this thesis, we demonstrate the range of UAV applications to assess glacier ablation and map snow algae in the North Cascades. The first chapter employs a low-cost, light-weight UAV to measure ablation of the Sholes Glacier using Structure-from-Motion technology and validates the measurements with outlet stream discharge data collected by the Nooksack Indian Tribe. We …
