RV Atlantic Twin in Staten Island, New York during mobilization for coring cruise AT-84-1. RV Atlantic Twin in Staten Island, New York during mobilization for coring cruise AT-84-1. Thirty-foot "Alpine Geophysical Pneumatic Vibracorer" in travel position (lower leg folded up) along the starboard side of the RV Atlantic Twin. Lower leg folds down into water before deployment (also at Staten Island, New York, AT-84-1).
Nancy Friedrich Neff, representing the University of Rhode Island (URI), and Captain Wally Van Horn (Alpine Ocean Seismic Survey, Inc.) with "Alpine" crewman in the wheelhouse of RV Atlantic Twin during cruise AT-84-1. From left to right, Larry Redling (Mate), Archie McCabe (Cook), Chuck Dill (Contractor's Representative) and Captain Van Horn (left rear) with four of the "Alpine" crew on the aft deck of the RV Atlantic Twin during cruise AT- 84-1. "Alpine" deck crew for cruise AT-88-1 with a view of the sound source for the ORE "Geopulse" seismic-profiling system that was used to verify targets before coring.
Seismic record being used to verify a target during coring cruise AT-88-1. Vibracorer in horizontal position prior to deployment. Once deployed the vibrating head rides down the aluminum I beam, and the core is taken through the hole in the base plate to the left. Pictures below show the core cutter protruding through the base plate. The vibrating head and the air hoses that deliver air from the compressor to power the corer.
Compressor that supplies pressurized air to the corer. Close-up of unused core liner with a core cutter attached and ready for use. Vibracorer with lower legs in position for coring.
Vibracorer in vertical position, ready to be lowered to sea floor. corer image Vibracorer taking a core in shallow water.
Vibracorer back in horizontal position in preparation for core retrieval. Large wrench holds core barrel so the core cutter can be unscrewed. Jack in use to support steel core barrel as the core cutter and plastic core liner are removed. Close up of full core cutter ready for removal.
Full core cutter and liner on deck after being pulled from the core barrel. Labeling, sectioning, and capping of the cores is underway. Cores (in plastic liners) stored on the forward deck after being labeled, cut into sections and capped. Core preparation at Woods Hole Oceanographic Institution (WHOI), Woods Hole, Mass. This machine was used to draw a knife blade through opposite sides of the plastic core liner before splitting.
An unidentified technician uses the core-splitting machine to draw a knife blade through opposite sides of the plastic core liner at Woods Hole Oceanographic Institution (WHOI). An unidentified technician slices the sediment lengthwise with a wire after the plastic core liner has been slit at the Woods Hole Oceanographic Institution (WHOI). Dr. Paul Gayes (right, Coastal Carolina College) and an unidentified technician use a wire to slice the cores lengthwise along the slits cut in the core liner. This process results in the core halves shown in a picture below.
Sally Needell (USGS) packaging and labeling the "working" and "archive" halves of each core in preparation for photographing and storage at the WHOI core lab. Nancy Friedrich Neff (URI) packaging and labeling the "working" and "archive" halves of each core in preparation for photographing and storage at the WHOI core lab. Core ready to be photographed at the WHOI core lab.
