Second Sampling 28/3/2012

This being my second sample I wanted to vary the results and I was lucky enough to go after a hour to two of medium rainfall. This I found really varied the results. The creek at no point was stagnant and was flowing at a fair speed. I hypothesised that this would increase the turbidity of the water and the moisture content of the soil as well as maybe a slight variation in the salinity of the water.

This shows the increased water flow from stagnate in first set of testing.

Start of creek 1

This is the main pipe of which the storm water comes from, to be honest I do not understand how the council can call this a natural creek in anyway after investigation all I could see was that this is directly fed  from storm water drains. You may also notice that on the left of the pipe the sandstone has blown out. Pollution is also very visible in the form of bottles. Other than that it seems to be healthy enough even though the water is so turbid do to the recent downfalls. 

Middle of Creek 2

These images show that the water was flowing but also collecting in large pools. You can also clearly see the stirred up water in the picture on the left. The rotting tree on the rocks was also a common sight, a few smaller trees had been displaced since I was last sampling even from the small amount of rain that we had had. 

Creek hitting harbour (Mangroves)

This i found was most evident where the water had really picked up as there were vast more amounts of water in here than there were as of last time. The mangroves themselves seem more swollen these were both same time (5pm after school) so there would be little or no tidal difference, which therefore had something to do with the amount of water. This water interestingly sort of passes through a channel of sandstone covered in a algae (blue green) where the mangrove only present on the left hand side also has its own water frontage from the sea so it works at that further down which was inaccessible because you would just sink into the mangroves, this channel of fresh/salt water coexists with the completely salt water of the mangroves which sits to the right and sometimes flows into the channel. 

Harbour.

The harbour has no change really as of its mass, the only real change you will get is when you go in the day due to tidal activity. I predicted no change in the results if i conducted them correctly and no unpredictable change occurred such as oil spillage from the Shell Refinery across the cove.
