2008-2009, Gannet Scientific Services, Research, development, production and evaluation of innovative grab sampling devices with a view to improving the quality and efficiency of sea-bed sediment sampling

Description

Author: Gannet Scientific Services. Report number: Report_08_P18. The current grab sampling devices used rely in an almost vertical angle of cable holding the grab jaws. The upward pull of the cable closes the grab jaws and for high efficiency relies on the vertical angle. Two new methods/devices were explored where the vertical angle was not relied upon and also where more than one sample could be taken at any one time.
