Hello! We are here to update again! This is our second post with regards to our trip down to Labrador Park on 7th July. It was our third trip down to the beach and our first data collection.
First, we decided on the 2 areas to be monitored. One is where Jocelyne’s group had plucked out the sea grasses which are currently growing back, and the other patch is chosen by us for comparison and further succession. Each area has a dimension of 25X25 cm. We hammered tent poles around the selected areas with a rock. It was an amusing moment because there were rocks beneath some of the areas where we wanted to hammer the tent poles. The rocks were muddy too so when were hammering like there will not be a tomorrow, mud flew everywhere, ha ha!
Then, we analyzed the 2 plots of sea grasses with the quadrate for future comparison and spent the rest of the time squatting around the patch of Thalassia that we have chosen and poking needles through the blades of it. (The holes, which are at the end of Thalassia, will be used to measure its growth rate.) Poking holes through sea grasses may sound easy but it was very tiring (and dangerous- Mr. Lim poked his finger and it bled. ><). We could not really see the bottom of the sea grass and had to feel around with our fingers. Although it was only a 25X25cm patch, there were many Thalassia and it was impossible to keep track of the ones that had been poked, so we had to estimate.
Also, we did some coastal cleanup on the beach while waiting for the other group and this was what we collected! 😀
Not to forget our findings!
Mr. Lim was thoroughly excited when he lifted the brick that Jocelyne’s group had placed as a marker the last time, and found that this little guy (as Mr. Lim calls it) was hiding underneath it. Indeed, marine creatures are professionals at camouflaging, none of us realized this crab was a crab when the brick was lifted!
We had planned to insert a video here, however, we do not know how to upload a video; adding media onto wordpress and youtube backfired on us! 😦
And last but not least, a crab of unknown identity!
Mr. Lim was yet again very excited about this as he and Jocelyne examined it closely. They took many many pictures and a video!
Again, we wanted to upload a video here, but D: So sorry!! Maybe, next time?
Here is a group shot with Jocelyne, our senior. 🙂
All in all, although the trip ate up our youth day holiday, we aren’t complaining! The day ensured much laughter and joy, as well as a deeper understanding toward our marine environment. We cannot wait for our next trip. Our bootees are ready! 🙂
