All the scientists on the JR are here to describe the rocks and sediments we are drilling. While most of the geologists are describing the cores by using their eyeballs and their brains (and maybe a hand lens and a microscope), Physical Properties Specialist Patrick Fulton is able to describe them by using instruments with cool names like Pycnometer and Whole-Round Multisensor Logger.
Louise and Sebastian (and Kerry!) are loggers, but not the kind that carry chainsaws and eat lots of pancakes. They are logging scientists. They have an important job on the JOIDES Resolution. They send scientific instruments down the holes the JR drilled in the seamounts and the instruments then fill in the holes in the scientists’ data.
Natural gamma-ray (NGR) spectrometry allows estimation of the elemental concentrations of K, U, and Th, which can be used to help interpret sediment composition, provenance, and diagenesis.
Petit tour d'horizon des différents labos à bord.
Lorsque les carottes arrivent sur le pont (toutes les 20 mn à 60 mn selon la profondeur d'eau et la profondeur du puits), elles sont découpées en sections d'1,5 m puis elles subissent toute une série de mesures.
