Database development and support for aquatics research. Development of web delivery tools to promote the sharing of data and current research results.Development of database management and analysis tools.Development of protocols for sampling stream temperatures using digital dataloggers.Development of stream temperature macros for import, QA/QC, and summary of data collected with digital temperature recorders.
My research interests focus on the development of models that can be used to help explain the current and future conditions of the stream system and the ultimate challenges climate change may bring. I hope to learn more about the modeling process and also would like to bring in the biological component to the stream temperature network we are now working on.
Research is important simply because the world around us is in constant change. Temperature data is easy and relatively inexpensive to collect but combersum to organize and analyze in a timely manner. Therefore on the stream temperature front we are data rich and information poor. Development of tools for managers and other researchers to use to expedite and organize stream temperature data on a temporal and spatial scale will allow us to utilize the data already available. This will give those on the management side the ability to make more informed decisions. Those in research will be able to use this information to better formulate questions and ultimately bring in the biological data. Tools that allow us to standardize the way the data is stored also opens up data sharing on a much larger scale.
Why This Research is Important
Development of a regional stream temperature database for use in model development.Assisted in development of a database that will be used to model food web changes in an Idaho reservoir.Writing of computer macros to import and summarize stream temperatures.
