Notes

We decided to record the time of the lower tide for 24 hours and will attempt to be consistent. Not sure which of the low tides other groups record?

There were occasional flecks of white foam coming from under the pier.  Around six anglers were on the pier and one had a cray pot with chicken carcass in it so that may have had something to do with the foam.

Two of the folders are falling apart.

Can the large plastic container in the cupboard be labelled? We assume that it is distilled water, not KCl. Please confirm.
