#12712 20 Feb 2019 Approved 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.

#12478 1 Nov 2018 Approved Notes:

Tidal outflow too rapid to use van Doorn at side of jetty and water shallow there too, hence, readings taken at south end of jetty where van Doorn functioned satisfactorily despite the flow and where the water was deeper.

NB. The van Loon meter only reached to 1.5m(ie it couldnt reach the bottom) due to the fast ebbing current.

Tide was low and water was running quickly. It was not practical to use the Van Dorn for bottom depth analysis. Early attempts resulted in Van Dorn wrapped around pylon and seaweed at end of pier made alternative site problematic.
