It's been sunny the past couple days which has made everyone forget all about the fog and rain that had heralded our arrival on KI. Although it's still cold at night and almost impossible to leave one's sleeping bag for 6AM low tides, the days are warm and sunny except for a few foggy hours in the morning meaning lots of electricity and hot water.
While everyone else has been busy working on their respective project, I find myself to be unfortunately without much work to do. As I said in my first post, I am waiting for my invasive Bryozoan to show up hopefully sometime soon, although I have no idea when - a Washington state lab lists settlement as occurring in June, while a paper from Newfoundland lists August. There is also the possibility that since KI lies near a convergence in ocean currents, with one arm heading north up the Bay of Fundy and the other half southwest along the Maine coast, there is no strong dispersal mechanism for the planktonic larvae (cyphonauts) of the Bryozoan. In other words, they won't reach KI and so I will never find them, even if I stay into August. Therefore, there is a lot of uneasy waiting currently. I am spotting kelp-filled pools all over the island, which tells me there is no shortage of substrate for the larvae to settle on. But so far, other than an exciting find of the native Bryozoan Electra pilosa on some Irish Moss, no bryozoan has shown up.
