| 英文简介 | ABSTRACT The primary goal of the proposal is to collect and quantify black carbon colloids (BC) in water samples from Lake Tahoe and Fallen Leaf Lake in the wake of the Lake Tahoe basin Angora fire. The sampling program will collect near-shore, mid-lake and outlet river samples from Fallen Leaf Lake and Lake Tahoe. In addition to sampling conducted by the project, we will leverage pre-existing sampling programs such as the UC-Davis Mid-Lake Tahoe Profile (MLTP), which collects depth profiles from the lake every 30 days. A proposal will be submitted in December to the NSF Hydrologic Sciences to interpret the data resulting from the SGER. Scientific merit Little is known regarding black carbon colloids, produced by incomplete combustion, in aquatic systems. However these nano-particles are now believed to be an important component of the global carbon cycle, the hydrologic cycle, global warming, accelerated snow pack and glacier melt, fresh water and marine chemistry and sediment geochemistry. Recent studies of BC in seawater and marine sediments suggest that BC may have a very long residence time in the ocean and fresh water bodies. These particles may also determine the partitioning of many toxic organic compounds in aquatic ecosystems. To our knowledge there have been no studies of BC colloids in a lake system following a major fire in its basin. Objectives . Collect and analyze BC in water samples from Lake Tahoe and Fallen Leaf Lake over a two year period after the Angora Fire. Broader impacts The project represents a rare opportunity to study the impact of a fire on BC colloids and determine how these colloids impact the aquatic environment. The results of the project may have wide ranging impacts on the global Earth Science Community as well as the Lake Tahoe community. For example, if the study can establish the residence time of BC in the lake, we will be able to determine the impact of BC on the lakes optical properties and chemistry over time. The results from the study may then be applied to other lakes and rivers. The data will be used by Federal and State policymakers and local planners to evaluate and implement environmental policy in the Lake Tahoe area. The project will communicate the results to the Lake Tahoe stakeholders and scientific community through journal publications and public meetings. |
