THELMA real-time data

ATTENTION: THELMA is  back on the lake and broadcasting live again.  If you're interested,  please check out some pictures of the retrieval and redeployment...

The Harp Environmental Lake Monitoring Ark (aka THELMA for short) was deployed in the summer of 2010 to gather high resolution water quality and meteorology data for investigations of lake metabolism, climate change, and water, nutrient, and energy budgets (among other things) on Harp Lake. The most recent data (10 minute averages before the hour) are available in the table and plots below. We thank the Harp Lake Association for their input into THELMA's design and for their support over the first years of operation. Please note that these data are provided "as is" as we have not yet verified their accuracy.
