Healy - Coring Systems

Healy is equipped with a JPC coring system for taking deep sediment cores up to 25 meters. The JPC core is deployed from the Starboard A-Frame using the 9/16" wire. The pivoting core bucket is bolted to the deck under the A-Frame (this can only be done in port). CTD operations can be carried out when the core bucket is installed, however the CTD must be lifted over the core bucket. Healy provides 4” core barrels and science users provide core liner. Healy typically has at least one 4,000 lb core head and one 5,000 lb core head in inventory.

video, which shows JPC operations on Healy, is available. Please contact the Healy Marine Science Coordinator to receive a loaner copy.

Healy also maintains a Gravity core system on board.

Other coring operations on Healy have included multicore and vibricore.
