Ubin Expedition with the Mega Marine Survey: Day 3-4

I'm back for the last days of the Expedition and it's a hive of activity at the work stations when I arrive in the afternoon of the second last day.
There's frenzied work on taking DNA vouchers, with phototaking, sorting and preserving going on all at the same time. And more field trips too!

I skipped the field trip and spent time in workroom activities. When I arrived, everyone was busy delicately removing tiny tiny porcelain crabs and other creatures living on sea pens. There's an amazing variety of marine life on our sea floor!
Another station is busy sucking up tiny tiny creatures found in sponges.
I had a hand helping with the sea pens. After which, Louis and I started on a huge pile of seaweed that was also obtained through a dredge. What can we find here? How exciting!
Wah, I found a strange little crab in a folded leaf!
And Louis found this baby Window pane shell with the animal clearly visible between the thin and transparent shells.
But the most abundant creature we found were brittle stars! There were also tiny sea urchins.
Then we moved on to sorting another batch of dredge which was full of countless tiny clams, many were shaped like a teapot with a little spout. There were also lots of animals with a tusk-like shell. Belonging to Class Scaphopoda and are not gastropods or bivalves, we rarely see these except in a dredge.
Dredge surveys for the day had also turned up a wide variety of echinoderms including some very large sea stars (not in this photo).
Another delightful find from the dredge is a tiny slipper lobster!
Rene and Yen-Ling are hard at work processing all the finds that have been sorted out.
Not everything that we catch is preserved and killed. These horseshoe crabs were carefully removed from the dredge.
And we released them on to the shore.
The next morning, as we waited for departure, we had a brief tutorial on 'pods': amphipods, isopods, copepods, from Kristine White, the expert on these critters. They are found everywhere, but she is particularly interested in those that live in other animals. Wow. There is still so much more to learn about our marine life!
And all too soon, it was the end of the first of a “mini” expedition (5-9 Mar 2012). This first expedition was meant for us to test out techniques, nail down certain issues and basically prepare ourselves for the next expedition. More about the last days at the Expedition on the Mega Marine Survey blog.

The Real Expedition will be in October and also focus on Singapore's Northern shores. The third Expedition will focus on habitats found in the Singapore straits and will be conducted in 2013.

Ordinary people can make a difference in these Expeditions! Come join the Mega Marine Survey to help us learn more about our shores!
