Tracy’s Way – Exploring the Lab

After several days of travel where the rough weather had us all lurching around a heaving and rolling ship like seasick zombies, we finally arrived at our first drilling location and started drilling rock core. While all of the scientists on board the JR have their own areas of research and individual projects relating to the Expedition goals, as a team we are also responsible for collecting a lot of basic information about the cores…

Exp359.25thOct. Downhole measurements! A small lab in a hole !!!

Drilling operations on the site 1466B ceased around 9am today and logging will start in the evening. Downhole measurements will complete core sample analyses . They will provide continuous records of physical and chemical properties of the sediments or of the rocks in situ: porosity, permeability, density, natural radioactivity, electrical resistivity… Triple combo  (http://rosetta.iodp.tamu.edu/A/TechDoc/8244?encoding=UTF-8<) contains tools measuring these parameters. Others tools contain sensors that can detail characteristics of the borehole wall or generate sound velocity data that…
