Measuring water chemistry in Double Keyhole Cave, FL

Detailed Description

Robert Scharping, a post-doctoral fellow jointly appointed by the USGS and the Woods Hole Oceanographic Institution (WHOI) measures water chemistry 40’ underwater and underground in Double Keyhole Cave near the coastline of Tampa Bay Florida. Robert is identifying the microbes and chemical conditions supporting chemosynthetic production of organic matter that is expelled from springs along the coast line and may contribute to recurring harmful algal blooms in that region. Diving in this habitat requires both courage and extensive training.
