The Antarctic Circumpolar Current is the planet's most powerful and arguably most important current. It is the only current to flow clear around the globe without being diverted by any landmass.It con...
The strata of hot dry rock (HDR) are usually igneous rocks with high temperature which are challenging for drilling activities. This paper deals with the key technology and research of turbodrills, in...
The theme for this conference is “Building on Today’s Efficiencies for Tomorrow’s Market.” This will be the basis for the technical agenda and discussion topics.Our industry is enduring one of its mo...
The performance of gas-drilling (drilling oil and gas wells with air, nitrogen, or natural gas) is very unpredictable in many areas due to lack of proper design of drilling parameters because of limit...
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...
Certain low-molecular-weight gases, such as methane, ethane, and carbon dioxide, can combine with water to form ice-like substances at high pressure or low temperature. These compounds, commonly calle...
A rich mosaic of disparate crustal types characterizes the Earth beneath the sea. Although "normal" oceanic crust approximately 7-km thick is by far the most prevalent, abnormally thick oceanic-type c...
Since the inception of the Deep Sea Drilling Project (DSDP) and during the Ocean Drilling Program (ODP), scien-tific ocean drilling has been almost wholly confined to outer-shelf water depths or great...
Knowledge of the composition of oceanic crust is critical for calculating the fluxes of mass, heat, and volatiles from Earth's interior to its crust, oceans, and atmosphere. In the great debate over c...
Earth science disciplines focused on investigation of climatic, ecological, or tectonic change as recorded in geological deposits (e.g., paleoceanography, marine micropaleontology, paleoclimatology, p...
The year 1967 was spent preparing for Leg 1 of the Deep Sea Drilling Project (DSDP). Because it was believed that graduate students, instead of professors, would staff the continuous expeditions, I jo...
Exactly one year before man landed on the moon, on July 20, 1968, another scientific undertaking began that was much less publicized but perhaps just as important in its ultimate contribution to scien...
Understanding of Antarctica's climate and ice sheet evolution remains fragmented due to a paucity of outcrops and drill cores that contain deposits from the Neogene (~ 23–2.6 million years ago), when ...
Using a specially designed hot-water drill to cleanly bore through a half mile of ice, a National Science Foundation (NSF)-funded team of researchers has become the first ever to reach and sample the ...
This winter, when many people’s imaginations were fixed on the North Pole, a small group of scientists has been working on the other side of the planet. In round-the-clock daylight and frigid temperat...
