The pool
The deep test pool at McLane "You haven't seen our pool before, have you?" Tim asked. Clad in a hard hat and steel-toe shoes, he had just moved a crane to lift a 60-kg pump into the water. The pump hung suspended just below the surface, while a rubber duck floated alongside. I peered over the edge, expecting to find the bottom just below the pump's frame - but I didn't. It was 50 m below, down a long, clear column. A few minutes passed, and the pump came to life, sucking water through an inlet at 30 L per minute. The small plastic ball that normally blocks the inlet disappeared into its chamber, and small bubbles revealed the level of turbulence. I was excited to see this evidence of the pump working - since I had set it up. Earlier this week, I had the opportunity to visit McLane Research Labs in Falmouth, MA and get trained on a new piece of equipment: high-volume underwater pumps. WHOI scientists, including my old postdoc lab, have used McLane pumps to colle
