James Cook returns to the Pacific

James Cook returns to the PacificAmongst fireworks and ships' sirens heralding the stroke of New Year RRS James Cook released its tethers from the rail-tugs that had guided her through the Panama Canal and exited the lowest basin of the Miraflores Locks to enter its spiritual home - the Pacific Ocean.

Captain James Cook was the greatest European explorer of the Pacific. He led three voyages aboard HMS Endeavour, Resolution and Discovery (1768-1779) to observe the transit of Venus; chart New Zealand, the east coast of Australia, Alaska to Kamchatka, and many of the Pacific Islands; and make the first circumnavigation of Antarctic. Cook and the names of his ships are indelibly linked to the island nations of the Pacific.

Following a two cruise campaign undertaking geochemical and geophysical studies of the Caribbean island volcano Montserrat, RRS James Cook has now embarked on JC021 - a Cardiff and Southampton-led cruise to survey exposures of lower ocean crustal rocks exposed at Hess Deep.

This unique, >5000 m deep, tectonic window developed the junction between the East Pacific Rise and the western tip of the Cocos-Nazca plate boundary will be subjected to detailed bathymetric survey using the Remotely Operated Vehicle Isis and sampling with the wire-line BRIDGE drill. JC021, funded by the UK-Integrated Ocean Drilling Program, will be used to locate sites for future deep coring using the re-fitted IODP drillship JOIDES Resolution, aptly named after one of Cook's ships.

Such holes will complement the on-going programme of drilling an intact section of ocean crust being undertaken at the nearby IODP Site 1256 with major involvement of NOC scientists.
