WebGRAVITY CORES (GC) - A Gravity Corer is a very simple design: an empty core barrel with weights on top and a 'core catcher' in the bottom. It is lowered from a ship and allowed to free-fall into soft sediments; the weights on top driving the barrel into the "mud".

Webgravity: [noun] dignity or sobriety of bearing. a serious situation or problem. WebA box corer was used for sample collection to investigate nodule abundance, sediment characteristics, and meiobenthos. The exploration work involved bathymetric mapping with a swath bathymetric system and seabed sampling with giant box corer. Only one box corer was successful and so was not used for comparison. WebSo, if gravity pulls everything down, then why don't things on the bottom of the Earth get pulled down into space? In this episode of Crash Course Kids, Sabr... ra 7649
