Yesterday (27/3/12) I went and got my second set of samples.
Point A's water was pretty similar in condition to the first time, a bit of sea weed, no pollution, but the only real difference was that it was low tide.
Point A's soil was a lot different to what condition it was before. The soil was very clay like, thick, compared to last time when it was not clay like at all and it was very easy to dig up.

Point B's water  was similar to last time very sea weedy, although this time there seemed to be a little bit more sea weed but there was a big difference. POLLUTION- there was pollution all along the shore line (rubbish, wrappers, string, and even a back piece of a bikini top that was very eroded).
Point B's Soil had basically no difference at all.

WHY WAS IT DIFFERENT AND IT'S EFFECT ON RESULTS

Point A's soil- IM guessing dure to the rain and then activity on it straight after, which can effect the results majorly.

Point B's water- Pollution has obviously came through recently which also means that the water could have been polluted aswell, I guess I will just have to way until I do my testing.
