Hello,
Winogradsky column by A. Kavalarakis and P. Kapaniaris
Our samples were taken by Anauros (local beach of Volos, Greece) during our university field trip. We already had prepared the necessary tools:
ü  One plastic bottle of 1.5l
ü  One plastic bottle of 0.5l
ü  One egg
ü  Some small paper pieces

We went there and we followed specific steps:
Gather sea sediment  and make a hole in the middle
Put the paper and the egg inside, make a mixture
Put it inside the bottle (2/3 parts of the big bottle)
Finally, filled up with water


Then we left it in a light place and took some photos during the days of the experiment.

Day 1,
 At the first day of our experiment we placed our column in a bright spot and sealed

 Day 10,
 We can see the water bluring and changing color and becoming yellow. This is a result of the photosynthesis of  the phutoplankton.

 Day 27,
We can see the color changed in to red. Due to FeO which can found it in sea sediment.

  1. So you mean that the pink colour is due to the Ca from the egg shell? Really? How?
