Many-ribbed Hydromedusas

So how often are you able to use the term many-ribbed hydromedusas in casual conversation! Margie from Cocoa Beach writes that these small, clear, thick jelly disks washing up on shore by the hundreds today are harmless. We'll be up that direction Saturday for the Sea Turtle Lighting Extravaganza, so perhaps we'll find some and get pictures.

Margie also tells us that they've had some upwellings in Cocoa Beach. "Recently, the water temp at North Lori Wilson dipped to 74 degrees, from mid-80s the week before. It happens in isolated spots, no telling where on any given day." According to Wikipedia, an upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water.
