Atlantis II Core Sampling
In order to gather a thorough understanding of the geological history of deposits in the
Edmund vent system, we plan to run shallow core samples (10m depth) in the sediment
plain. These tests will provide substantial data about how each part of the vent field and
plain formed up until modern times.
Procedure
Identify semi-regular randomized positions in geological areas of interest
Using a 10m core sampler on AUVs and transportation vehicles collect core
samples, plugging holes with an environmentally safe plugging compound
Perform x-ray diffraction on cores to identify marine minerals and clays
Core logging
Textural analysis with laser probe
Grain size analyses using a settling column
Test for particle size, shape, and porosity
X-ray core photography
Send cores to surface for any additional testing needed
