Data from various environmental monitoring stations at the Griffy Woods property can now be collected over the Internet as well as displayed on a Web page thanks to funding from an NSF FSML grant that allowed for purchase of necessary equipment and software. Data from a weather station and from a weir maintained by Indiana Geological Survey (IGS) may be viewed by visiting the appropriate link below. Also available for viewing are data from University Lake sampled by Spencer Hall's (IU Department of Biology) instrumentation on the lake.

	The Griffy Woods micrometeorological station has been collecting data since Fall 2007. Such readings as air and soil temperature, net radiation, wind speed, and relative humidity acquired from the station are critical components for such things as the calculation of local energy budgets used in modeling of plant growth conditions. The continuous collection of such dynamic measurements is important to multiple studies at the IU RTP.

	The broad-crested weir is located in Sycamore Valley on the south fork of Griffy Creek. It allows for the measurement of discharge by knowing the height of the water above the weir. The water height is measured and recorded using a pressure transducer and data logger. The weir will handle a maximum of 235 cubic feet/second (cfs) of water before the water flows around the flood plain. Creek water flow in cubic feet/second (cfs)
	With a grant from the IU Center for Research in Environmental Sciences (CRES), Spencer Hall (IU Department of Biology) was able to set up real-time meteorological and thermal monitoring instrumentation on University Lake to gather data for his research. Lake temperatures from the surface to 8 meters below the surface are displayed on our Web page. Dissolved oxygen amounts and other data are also displayed. University Lake data
