1 November 2009
The vessel continued its long voyage to Townsville, Australia. Presently,
the JOIDES Resolution
has sailed 2812 nmi on this transit at an average speed of 11.2
knots. During this week's portion of the voyage, the vessel
crossed the equator, transited the Solomon Sea, and is
presently sailing across the Coral Sea. There are 340 nmi
remaining to the voyage with an expected arrival in Townsville in the
morning of 3 November 2009, which is one day ahead of schedule.
this transit week, all remaining sampling parties were conducted. Cores
recovered from Sites U1347, U1348, U1349 and U1350 were sampled for postcruise
research. All samples were cut and properly prepared for transport.
the beginning of the week, all descriptive lab groups completed their
descriptions of the last thin sections produced from Site U1350 samples.
Likewise, the geochemical lab group completed the ICP-AES analysis of 43 lava
samples from Site U1350. The data were reduced and interpreted, and the
results written up for the site report. The lab group also produced a more
user-friendly data reduction routine for shipboard ICP-AES data.
focus of all lab groups shifted entirely to report writing, finishing database
entries and quality control, as well as coordinating the individual postcruise
research plans. By the end of the week, all lab groups had completed their last
site report and submitted revised methods sections. Also, all individual
scientists have submitted tentative titles of research papers, which they
intend to write based on samples and data from this expedition.
Technical Support and HSE Activities
the week of October 26 the shipboard labs were busy finishing up processing
cores from the last site. Cores from all drill sites were laid out for
postruise sampling in a series of sample parties. A fire and boat drill was
held on October 30 for the entire ship's complement.
