caption_attribution_description: Giant box corer (spade corer); used on research vessels to take undisturbed surface samples (50 x 50 cm, 50 cm deep) from ocean floor sediments. Developed by USNEL (United States Navy Electronics Laboratory) during the nineteen seventies. This image shows the deployment of the corer from the research vessel POLARSTERN in the Southern Ocean off the shelf ice edge.
context_page_description: The Box corer is a marine geological sampling tool for soft sediments in lakes or oceans. It is deployed from a research vessel with a wire and suitable for any water depth. It is designed for a minimum of disturbance of the sediment surface by bow wave effects which is important for quantitative investigations of the benthic micro- to macrofauna, geochemical processes, sampling of bottom water or sedimentology.
