OSIL (Ocean Scientific International Ltd.) recently supplied a Mega Corer destined for use in monitoring the benthic layer associated with the Gulf of Mexico spill site.
The unique hydrostatically damped coring method of the Multiple Corers (penetration rate ~1 cm/s) allows for the collection of a truly undisturbed sediment sample from the seabed, including the sediment/water interface and overlying supernatant water. Each of the four corers, Mega, Maxi, Midi and Mini, provide a simple and reliable way of collecting the most accurate sample possible by eliminating the bow wave generated by traditional corers. This is of great help when assessing the extent of oil dispersal either from cuttings piles or spill sites.
The rugged frame of the corer is made of 316 stainless steel and the core tubing itself can be manufactured from acrylic, poly carbonate or stainless steel, depending on the requirements of the customer. With a deployment rate of approximately 1 metre per second on the descent coupled with a retrieval rate at winch speed the corers are ideal for rapid assessment work.
OSIL’s corers are currently used worldwide by companies such as IAEA, Petrobras, Altima, NOC and The University of Aberdeen for sampling in applications related to environmental impact assessment, geochemical analysis, interstitial waters and biological survey.
