Multiple Corer for Taiwan
Sediment corer manufacturer Ocean Scientific International Ltd (OSIL), UK, has built and equipped a 12-station Multi Corer system for use by the National Taiwan Ocean University (NTOU). The hydrostatically damped Multi Corer is capable of collecting up to 12 high-quality undisturbed 600mm long samples (including the overlying supernatant water). The corer is constructed from stainless steel and features detachable core assemblies, which enables the core tubes (or if necessary the entire core tube assembly) to be detached from the corer for analysis or storage.
The NTOU corer is equipped to handle two different diameters of core tubes: the standard 110mm and the smaller 65mm. The changeover process is swift and easy with one bolt to undo to swap core tube assemblies, allowing a large number of samples to be taken in quick succession in any one mission. The core tubes are sealed top and bottom once the sample has been taken, allowing rapid retrieval of the corer without jeopardising sample integrity.
The corers are easily customisable and delivery times for the corers and spares are low, meaning last-minute cruises can be catered for and systems can be kept in constant use for many years.
