At 11:44 (lowest tide=0.6m), we counted the number of barnicles on a rock face that was not completely verticle. Therefore, we counted in a line from the surface of the water at low tide to the surface of the water at high tide. We used 10 10x10 transicts. The total area measured was 2900 centimetres squared.
The data was as follows:
Transect1- 70-75
Transect2- 156-160
Transect3- 180-185
Transect4- 67-72
Transect5- 70
Transect6- 249
Transect7- 150
Transect8- 289
Transect9- 70
Transect10-30
Total number of transicts= 1340 (+/- 13)
Temperature of water= 11.8 vs 11.2-11.4 (at 2 am) Celsius degrees
