Box core

One of the many things we want to study is the oxygen profile in the very top sediment. For this we use a “box core”, or as the crew has named it “Brutalis” (see picture below), as it is quite dangerous at big swells, as it swings heavily to the side of the ship.

So far we have tried to take box cores 3 times without any luck. The sediment is so hard that “Brutalis” cannot close around it, and therefore the core tilts inside (picture below). A perfect sample would be horizontal and having water on top.
