Coring

Today we examined our cores that we collected on the 22nd of October. We were split into two groups, and the group that I am in were given Core 2 Drill 1 and Core 2 Drill 2. Core 2 Drill 1 goes from 0cm depth to 64cm depth and Core 2 Drill 2 goes from 50cm depth to 150cm depth, meaning that there is a 14cm overlap.

Our Cores
We then made a log of the characteristics of the cores that we could see without doing anything to them, concentrating on their colour changes, vegetation densities and shell content. The upper part of the cores was densely vegetated, whilst the deepest part of the cores contained some gastropod shells.

After that we cut out 26 samples from the centres of the cores to be heated before we can study them separately to see what they are made of and what their Zinc concentration is. Keep an eye out over the next few weeks for an update on how everything goes.
