This hefty center-pivot sampler
is designed to sample unconsolidated sediments from soft ooze to hard-packed
silts from deep lakes and near offshore. It brings up virtually un-
disturbed, unwashed samples to the surface from any depth. Its specialty
is sampling benthic organisms living at or immediately below the water/bottom
interface and sediment containing a significant population of non-sessile
forms.
The current Shipek® is based upon the patented
design of the late Carl J. Shipek, noted oceanographer, and is manufactured
by Wildco® under license. It consists of two concentric half cylinders,
the outer of which is the sampler body. A cocking wrench, included,
is used for winding the torsion springs. A safety hook prevents their
premature release when held in the safety position. Cast into each
end of the frame are large stabilizing handles which, along with its
weight, hold the sampler upright during descent. |
