| Summary: | <!--!introduction!--> The exposure of New Zealand’s snow and ice fields to significant inputs of aerosols from Australian bushfires makes NZ an ideal site to study albedo's physical and biological controls. Under projected scenarios of increased frequency and severity of Australian droughts and bushfires, snow tainted by Australian aerosols will become increasingly common in NZ. Likewise, snow/ice algae are expected to respond to climate warming by increasing abundance, biomass, and distribution. Because the bushfire season coincides with the melt period, when snow algae undertake vegetative growth with the availability of liquid water, establishing the effect of bushfire aerosols and algae, and their interactions, on the melting of glacial systems is urgently needed. We present albedo measurements from two controlled field experiments. The experiments at Tasman Saddle used treatments applied to plots with a full factorial experimental design to determine the effects of aerosols on albedo and the ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ... |
