The Effects Of Warming Temperatures, Fire, And Landscape Change On Lake Production In Mountain Lakes, Alberta, Canada, Amber Elizabeth Gall
The Effects Of Warming Temperatures, Fire, And Landscape Change On Lake Production In Mountain Lakes, Alberta, Canada, Amber Elizabeth Gall
Electronic Thesis and Dissertation Repository
Many factors could be causing the widespread eutrophication being observed globally, including natural and human factors. In the mountainous regions of Alberta, Canada, warming temperatures, increased fire occurrence, and greater landscape disturbance could increase lake production. To determine the effects of these factors, proxies of lake production preserved in lake sediment records that span the last 1000 years were measured. These records are from two lakes that have not been affected by direct nutrient inputs from human activities; one in Jasper National Park and one from the Hinton area (Alberta). The results highlight that there is little effect of fire …
Evaluation Of Temperature Anomalies And Ocean Productivity During The 2004 Sumatra-Andaman Earthquake, Cora Byers, Brenna Mcnabb
Evaluation Of Temperature Anomalies And Ocean Productivity During The 2004 Sumatra-Andaman Earthquake, Cora Byers, Brenna Mcnabb
Student Scholar Symposium Abstracts and Posters
The oceanic productivity of the Indian Ocean and temperature anomalies prior to the Sumatra-Andaman earthquake (MW =9.3) and tsunami (December 26th 2004) were studied. Data was obtained via NASA’s Giovanni program to determine the effect on phytoplankton (primary producers) and temperature changes over the region of the earthquake. Seasonal trends were visible in the concentrations of chlorophyll a, coccolithophores, cyanobacteria, chlorophytes, diatoms and absorption coefficient, in addition to storm trends.
