WebOct 30, 2024 · Gravity corers are inserted into the sediment using a hammering method (Fig. 1 b), whereby a ram or hydrostatic motor is used to lift and release a weight to hammer the corer into the sediment (Wang et al. 2011 ). WebThe HTH Gravity Corer The Principal You can vary how far the corer penetrates into the sediment by selecting one or two of the rings furthest down on the corer. The corer is lowered until it is 0.5-1m above the sediment surface, when pause for about 10 seconds to allow the corer to stop oscillating and/or rotating.
