Yes, we’re in the same place as yesterday. The captain of our ship said that last night, winds of 80 knots (88 mph) were expected, and so he did not want to take the ship out into open water. 88 mph!! That’s hurricane force winds, and indeed during the night the winds howled and the ship was buffeted about.

I got up in the night and went out onto the deck at 3:45 a.m. The deck was illuminated with moonlight, many stars were visible, and the snow glowed on nearby mountains; however, the wind was strong and I held onto the railing to make sure I wouldn’t be blown overboard. Moments like this, alone in the glory of nature, are the moments I treasure above almost everything else. When I came out again at 6:15 a.m., the sun had risen, the winds had died down and the sky was mostly clear. If nothing else, the weather here can change quickly.

By the time we were ready to go into the field, it had started to rain again, but this time only lightly, and the winds, and thus the sea, remained calm. We headed toward what we initially thought was a lake but instead turned out to be a shallow inlet of the sea, accessible by zodiac. We split up and Jim headed toward a large, glacier-fed waterfall because of his special interest in rheophytic bryophytes, those that grow on rocks in moving water. Some rheophytes are only in the water seasonally, following rain patterns, and others are permanently wet. Juan headed up the mountain, toward the snow, because the moss genus he is working on for his dissertation often grows on exposed rocks. Blanka collected along the shore of the small inlet, and I headed for the rocky peaks near the shore and the pockets of forest in more sheltered sites.

No, we’re not bioengineering treat-dispensing shrubbery. It’s just snowing a lot this winter, coating everything in what, on some days, looks like a thick layer of Marshmallow Fluff.
