Super-long Corer for Study Sampling

 
OSIL's (Ocean Scientific International Ltd.) range of Multiple Corers are the only way of collecting a truly undisturbed sediment sample from the seabed. Each of the four corers, Mega, Maxi, Midi and Mini, provide a simple and reliable way of collecting the most accurate sample possible. The corers use a unique hydrostatically damped coring mechanism (penetration rate ~1 cm/s) to attain the undisturbed sample. The hydrostatically damped head allows a true representative sample that has not been disturbed by the bow waves seen in front of traditional corers.

The rugged frame of the corers is made of 316 stainless steel and the core tubing itself of acrylic. 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, BP and The University of Aberdeen for sampling in applications related to environmental impact assessment, geochemical analysis, interstitial waters and biological survey.
