Paleoceanography of the eastern equatorial Pacific during the Neogene: Synthesis of Leg 138 drilling results
The primary objective of Leg 138 was to provide detailed information about the ocean's response to global climate change during the Neogene. Two north-south transects were drilled (95° and 110°W) within the region of equatorial divergence-driven upwelling (and thus high accumulation rates and resolution) and spanning the major equatorial ocean current boundaries (and thus recording a high-ampli...

متن کاملTerrestrial biome distribution in the Late Neogene inferred from a black carbon record in the northeastern equatorial Pacific
The appearance and expansion of C4 plants in the Late Cenozoic was a dramatic example of terrestrial ecological change. The fire hypothesis, which suggests fire as a major cause of C4 grassland is gaining support, yet a more detailed relationship between fire and vegetation-type change remains unresolved. We report the content and stable carbon isotope record of black carbon (BC) in a sediment ...
متن کامل16. Late Neogene Paleoceanography in the Western North Pacific
Late Neogene paleoceanographic history in the western North Pacific is discussed on the basis of: (1) Td (diatom temperature) values, (2) species composition, and (3) the structure of diatom assemblages at Sites 579 and 580. These factors provide a record of fluctuations of the past position of the subarctic-subtropic front because these sites lie within the transition zone between the modern d...
متن کاملResponse of the Equatorial Pacific Seasonal Cycle to Orbital Forcing
The response of the equatorial Pacific Ocean’s seasonal cycle to orbital forcing is explored using idealized simulations with a coupled atmosphere–ocean GCM in which eccentricity, obliquity, and the longitude of perihelion are altered while other boundary conditions are maintained at preindustrial levels. The importance of ocean dynamics in the climate response is investigated using additional ...
