Sampling of the organsims

The acidification experiment will last for 3 months. In order to study the progress of the acidification impact on the organisms 3 replicates of each organsim/tank will be sampled in a twenty days basis . During this period additional samplings of Hexaplex and Nassarius are planned (every 10 days).

First we measure the length of the studied organisms to record their growth.

Then we choose randomly three samples from every organism and store them in a prelabelled bag.

Selection of Nassarius

Then we put them in liquid nitrogen in order to preserve their biofilm and structure intact. Finally we store them at a -80oC freezer.
