Megafauna (and microfauna) sampling!

Fishing!
Last night was the final chance for uninterrupted sleep and it was a marvelous sleep! The rocking of the ship lulls me to sleep before my head even hits the pillow. This morning I woke up bright-eyed and bushy-tailed, ready for what the day would hold. Why was I so excited this morning (besides the fact that I am usually excited about all things nautical)? Because this morning we were going to be sampling the megafauna, i.e. fishing!!! We set up the rigs, cast out the lines, and waited for the unsuspecting fish to take a bite of the colorful lures. On the last cruise aboard the Kilo Moana, the deck became a hive of activity as we pulled in multiple Big Eye Tunas. This time however, (almost) all our hopes were dashed. Ming was the only one to successfully haul a fish onto the deck. The rest of us waited around to no avail. I guess the fish just weren’t biting. Long after everyone else had given up, I sat at the stern with my legs dangling over the edge and watching for fish to pull on the lines. After 3 hours of trolling, we finally decided to call it a day. No more fishing. My guess is that the fish heard rumors that the crazy girl with no mercy (when it comes to fish) was back in the neighborhood and decided to lay low for the day. My reputation precedes me!

 After that rather lack-luster morning, we deployed our noon cast and worked on our experiments. This time my workload has more than doubled because there are fewer scientists on this trip than the last one. I am still establishing the chlorophyll depth profiles but now I am also working on the temperature-shift experiments (using chlorophyll abundance as an indicator) as well as preparing the sterivex filters. The sterivex filters are frozen and analyzed at a later date, but all the chlorophyll data is available day by day. I’m able to see the results within 24 hours. This makes everything so much more exciting!


All the scientists gather around the CTD
like piglets hungry for milk!
