Expedition 330: Louisville Seamount Trail
December 2010 – February 2011
In December 2010, an international team of scientists set sail on the scientific drilling vessel JOIDES Resolution for an eight-week IODP expedition to the Louisville Seamount chain.
The expedition set out to examine the:
- possible motion of the Louisville hotspot and its geodynamical implications
- eruptive cycle and geochemical evolution of the seamount trail
Two scientists from the University of Leicester sailed on Expedition 330, Dr Rebecca Williams (Petrologist) and Dr Louise Anderson (Logging Staff Scientist). Over the course of 8 weeks the expedition drilled 1114 m of sediment and igneous basement across eight holes at six sites located on five different seamounts. In total 806 metres of core was recovered, corresponding to 72% recovery. Two holes were logged during the Expedition, U1374A and U1376A. U1374A was logged with the Triple-combo (Density - Neutron Porosity – Resistivity & Gamma Ray sondes), Formation MicroScanner-Sonic string, Goettingen Borehole Magnetometer (GBM) and Ultrasonic Borehole Imager (UBI). U1376A was logged with all the previously listed tools excluding the UBI.
Excellent downhole data were acquired including borehole imagery, which will aid in the calculation of the number of massive igneous units drilled and fill in gaps where no core was recovered.
