This morning at 11 30 am, we divided ourselves into 2 groups. Zahida and me collected data from the spiritual centre spot, while Yuri and Ghazi did that on the other spot.
I used classical triangle method to measeure that the tide change (relative to the standard we set yesterday) was -1.8 metres. Therefore the calculated tide height is 2.3 - 1.8 = 0.5 m, this matches our predicted tide height, which should be 0.4 to 0.5 metre.
The temperature is 11.3 /11.4 ºC.
Then we measured the numbers of barnacles in each square (10 inches · 10 inches) of area.
The data of barnacles will be posted later in form of excel.
Zijian and Zahida.
