Glass Bottom Float (GBF2) collects data from over a dozen different sensors, processes these data through computers, and then combines subjective opinions and concerns, expressed by people based on bodily experiences formulated in language through interviews, to a situated descriptor of the current conditions of 'being in the water'.

When the buoy is deployed, the number displayed below is the current swimming pleasure measure. On a scale from 1 to 10, it summarizes how beach visitors describe the quality of going for a swim today. For more information on water quality, click on the "data" tab.
