mounting the VTLC on the multi-core.
The multi-core is a specialized device that lands on the bottom and then lowers an array of eight collection tubes into the sediment. When the multi-core is lifted off the bottom so it can be raised back to the surface, lids snap shut on the tops of the core tubes and feet swing down to trap the sample in each tube for recovery. It doesn’t always work, however, particularly when the weather gets rough and the water depth increases. When a multi-core fails, the sample-tubes come up empty, often with a bit of mud on the feet. The coring team members sigh and curse and the multi-core down again. Sometimes, nothing seems to work.
