GSA s dynamic online journal, Geosphere, posts articles online regularly. Locations and topics studied this month include the Moine thrust zone in northwestern Scotland; the Eastern California shear zone; implementation of OpenTopography ; the finite evolution of mole tracks ; the southern central Andes; the work of International Ocean Discovery Program (IODP) Expedition 351; and the Fairweather fault, Alaska, USA.

Kaimei (in the image immediately below) positioned the ship above the drilling site. Drill operators then lowered into the ocean a 131-foot-long “Giant Piston Corer” via a winch. The corer then proceeded to drill into the ground, ultimately capturing sediment from 124 feet down.

In a blog post, IODP scientists said that the ultra-deep coring operation was very challenging. But it was clearly worthwhile. The IODP team now has plenty of core samples to study, and they’ll likely find loads of rare-earth elements.

Norwegian offshore vessel operator Siem Offshore has hired Oslo-based TMC Compressors (TMC) to deliver a new marine compressed air system to be retrofitted onboard the JOIDES Resolution research vessel.
Former drillship JOIDES Resolution is a research vessel that drills into the ocean floor to collect and study core samples, to help scientists better understand climate change, geology, and Earth’s history.
For this research vessel, TMC will supply a complete marine compressed air system that consists of three large screw compressors plus refrigerant air dryers and filters to provide a constant supply of dry, clean air. TMC has not disclosed the value of the contract.
