Lab Park again!

21 02 2008

We left for Labrador Park on Tuesday during school, and reached there while the tide was still quite high.

The first thing we noticed when we reached was that the whole beach was covered in the green algae (Bryopsis).

We heard from Mr Lim and later, Ms Yang Shu Fen and Ms Siti, that these were seasonal though, so we weren’t particularly worried, although it did make the whole shore look dirty, unwelcoming and the water really turbid.

We also noticed that the construction works has been completed, as the barrier has been taken down. Another thing that our group is interested in is how the construction works could have affected the water quality at Labrador Park, so perhaps after the next group takes over us, they would notice a new trend!

As the tide was still quite high and Ms Siti and Ms Shu Fen hadn’t arrived, we started exploring the shore. We saw a small Moon crab

and some Fiddler crabs, as well as a little catfish.

Once the tide was reasonably low, the 6 of us (Si Hui, Si Ling, Mr Lim, Ms Siti, Ms Shu Fen and I) started our monitoring. Due to the excess Bryopsis floating about all over the place, it was really difficult for us to estimate the percentage cover of seagrasses. (Almost everything was covered under seaweed!) However, we still managed to complete our 33 random quadrats, and Ms Shu Fen and Ms Siti even spotted the Thalassia flower, which we heard was really rare!

It was also the flowering season for Enhalus, and Mr Lim spotted their flowers, although it hadn’t bloomed yet.

The Enhalus is the only species of seagrasses whose flowers have to be fertilised out of water; all other seagrasses complete their entire life cycle under water. “Seagrasses are so cool yeah!”

After monitoring, we punched holes in a little plot of Thalassia. This time, as we neglected to bring raffia and tent pegs, we improvised with chopsticks and bricks! With everyone except Mr Lim helping, the job was soon done, and as we left for the shore, we saw this huge catfish!

It was stranded by the receding tide and was hiding, when we ungraciously intruded into its presence and started snapping shots of it. It probably felt like a celebrity xP

We also saw markings in the sand which Ms Siti says looks like those made by Brittle Stars, although we didn’t see any 😦

Thus concludes our group’s last monitoring session at Labrador Park 😦 We will still continue coming down whenever we are free though, we are too attached to Lab Park! We will be going down again today during our RS block, just to look see and as Mr Lim says, picnic! (:

Special thanks to Ms Siti and Ms Shu Fen for coming down to help us!

Try looking closer at the Bryopsis. They can contain many small and tiny animals that look like part of the algae or dusty specks until you look closer. There’s slugs, amphipods and skeleton shrimp…

It has the just like you examine my head! A person looks to recognise a lot about this, just like you authored a e-book in it or something like that. I believe that you can do with just a few delaware. g. to help strength the content home a little, on the other hand in addition to that, that is wonderful blog. A wonderful study. I’ll absolutely come back.
