To access the sounds of Twin Lakes, go the the REAL website (http://www.real.msu.edu) and access a project using the Projects tab. Scroll down to Twin Lakes Soundscape. You will find a series of tabs that will provide access the information on the project including an overview of the project (Overview), the location of the sensor platforms (Sensor Locations), access to the digital acoustic library (Access Data), metadata associated with the sensor platforms (Sensor Catalog), a utility to plot the results of the acoustic analysis (Analysis), reports associated with the project (Reports), and photographs of the sites and location (Photos).
If there is further need for explanation or other information required, please contact Stuart Gage (gages@msu.edu).
Stuart Gage, Johnathan Hodge and Peter Grace designed a workshop entitled “Terrestrial Acoustic Sensor Applications Workshop”. The workshop was held at Queensland University of Technology in the Institute for Sustainable Resources. The workshop included members from Queensland Environmental Protection Agency, Victorian Dept of Primary Industries and Fisheries, CSIRO, the Australian Rainforest Conservation Society and QUT faculty. This workshop focused on application of acoustics to monitor ecosystem health. Participants discussed an array of ongoing research projects, the methods they use for ecosystem assessment, the types and successful implementation of automated species recognition technologies, the development and operation of automated monitoring technologies, as well as conducting demonstrations of acoustic signal analysis methodologies. A discussion and planning of future initiatives with EPA and other organizations provided a future direction. The participated were slotted into four major research components to facilitate future funding development. These were: Sensor Technologies; Soundscape Interpretation; Ecosystem Assessment and Data Stewardship. Jonathon Hodge, Peter Grace and Stuart Gage met to summarize workshop outcomes and to plan a long term strategy.
Digital Library Access
We have enabled access to a subset of our digital acoustic library. To access the library, use the Archives tab (above) and read the description of the types of acoustics that we maintain in the library. Log into the Library access system using guest (as the id) and guest (as the password). You will then be able to access several of the data sets available. For example, to access GH (GageHome) select GH from the list of available data sets and enter the query arena by selecting the Download button. In the Query arena you specify the Location (already done), Sensor at location, Year, Month, Day of Month, Time of Day, Hour (0) or half-hour (30). At each step in the query, you will notice that the number of files (and size of selection) will be displayed (reason for page refresh). Be carefil to limit your selection as I have been recording at this site for 8 years and 48 times per day.
Click Analysis Name and provide a label for your analysis. You will then be able to see ocillograms, sonograms and a bar chart of sound frequencies. You will also be able to hear the sound using the embedded player (top of chart).
Please let me have some feedback about the library access system.

Stuart Gage and Eric Kasten attended an Animal Behavior Workshop at the James Reserve in California sponsored by the the National Science Foundation. This two day workshop (October 16-17, 2008), entitled Bioacoustic Monitoring in the Terrestrial Environment, focused on needs, abilities and demonstrations.

The animation depicts the changing soundscape in a rural residential site in Okemos Michigan in April 2004 from 6 AM to 8 AM. Recordings are made automatically at half hourly intervals beginning in 2002. This 2 hour time is representative of the dawn chorus at this time of year.
