Own Experience

Our working group uses the saw to open sediment cores containing a high content of cold-water coral fragments. A special procedure is needed to avoid any disturbance of the hard coral fragment/soft sediment mixture. Before opening, the cores are frozen at -20°C for 24 hours. The core sections (length: 1m) are cutted lengthwise into two halves (archive and work halves). The surface of the core halves is rinsed with clean water to remove any cutting remnants. Afterwards, the cores need again 24 hours for defreezing before they can be further described and sub-sampled.
