Description and geochemistry of DSDP Leg 55 Holes
One of the objectives of Leg 55 was to investigate the Tertiary history of sedimentation and environment on the Emperor Seamounts after their volcanic activity. For the three... -
Geochemistry at DSDP Leg 55 Holes
The tops of the Emperor chain guyots, which were drilled during Leg 55, lie above the carbonate compensation depth (CCD), as well as above the foraminiferal dissolution level,... -
Occurrence of hiatuses PH and NH 1 through NH 7 in DSDP holes
Miocene paleoceanographic evolution exhibits major changes resulting from the opening and closing of passages, the subsequent changes in oceanic circulation, and development of... -
New calibration of Neogene radiolarian events in the North Pacific
New age models for twelve Deep Sea Drilling Project sites in the North Pacific have been produced, based on (in order of importance in our dataset) a recompilation of previously... -
