We spent the last 3 days trying to dodge the wind and dive within narrow windows of opportunity.

The good news is that the water has warmed up to 57 degrees, and the phytoplankton bloom seems to be deteriorating.

The light bulb tunicate, Clavelina huntsmani, is reproducing right now. Like other colonial tunicates, it broods its embryos. These light bulbs have a cluster of yellow eggs at the base of their pharynx.
