The Folger Pinnacle instrument platform was installed on August 23, 2010 and connected on February 2, 2011 by a combined team of Pelagic Technologies divers, the Bamfield Marine Sciences Centre (BMSC), and Ocean Networks Canada. Since then, a wealth of data has been gathered by instruments affixed to this 23m deep platform. However, in recent months, Dilumie Abeysirigunawardena, one of our data specialists, noticed a drop in the instruments’ data quality and sensitivity. Some stopped working altogether, while signals from others have gradually diminished. (See, for example, the drop-off in irradiance from our light sensor below – you’d normally expect June to be brighter than February!)
