Philippine Sea - Engineering Tests
Leg 124E gave ODP engineers the opportunity to evaluate new and modified drilling systems and
techniques in adverse operational conditions of high winds and seas, specifically to determine the
capabilities of the diamond coring system (DCS), the modified navidrill core barrel (NCB) system,
a prototype of the pressure core sampler (PCS), the redesigned extended core barrel (XCB), as
well as performance evaluations of ODPÍs coring techniques in deep-water chert sequences,
logging technology developed at Lamont-Doherty Geological Observatory, and the deep-water
dynamic-positioning capabilities of JOIDES Resolution. Six sites were investiagted during Leg
124E (Site 772 to Site 777).
