Okeanus Science and Technology LLC (Okeanus) has added custom-designed, deepwater box cores to its catalog of equipment available for lease.
As part of its suite of equipment, Okeanus offers clients a variety of box cores sizes. The most recent additions to Okeanus’ box core line are the largest class offered for leasing and have openings measuring 50 cm x 50 cm with a depth of approximately 60 cm. Fully laden by weights, the new box core design weighs nearly 1,200 lbs. The design of this box core allows single increments of up to 20, 35-lb weights to be easily added or removed from the frame. This ability to adjust the weights helps manage the penetration depth of the box core and increases the chance of obtaining an acceptable box core sample in a variety of sediment densities.
By combining a box core and a winch spooled with synthetic line, Okeanus can provide clients with a deepwater sediment sampling package. The addition of an Ultra Short Baseline System (USBL) and navigation package allows for exact geographic recording of where the box core makes contact with the seafloor and may be used to steer the box core to a preselected location. For biological sampling efforts, Okeanus carries custom-designed infaunal sieving stations that greatly cut down on the time required to process a sample.
All of these systems and others are available from Okeanus in Houma, Louisiana.
