Variations in the biological pump throughout the Miocene: evidence from organic carbon burial in Pacific Ocean sediments

Autor: M. Lyle, A. Olivarez Lyle

Publikováno v: Climate of the Past, Vol 20, Pp 2685-2700 (2024)

The biological pump, defined as the marine biological production and sedimentation of particulate organic carbon (POC), is a fundamental process for fixing atmospheric carbon dioxide in the oceans, transferring carbon away from the atmosphere to the

Biogenic sedimentation in the equatorial Pacific: Carbon cycling and paleoproduction, 12-24 Ma

Autor: Franco Marcantonio, Christine Piela, Jack G. Baldauf, Mitchell W Lyle, Annette Olivarez Lyle

Publikováno v: Paleoceanography. 27

[1] The equatorial Pacific is an important part of the global carbon cycle and has been affected by climate change through the Cenozoic (65 Ma to present). We present a Miocene (12–24 Ma) biogenic sediment record from Deep Sea Drilling Project (DSD

Data report: raw and normalized elemental data along the Site U1338 splice from X-ray fluorescence scanning

Autor: Katsunori Kimoto, Ed C Hathorne, Ann Holbourn, Thomas Westerhold, Mitchell W Lyle, T J Gorgas, Annett Olivarez Lyle, Shinya Yamamoto

We used X-ray fluorescence (XRF) scanning on Site U1338 sediments from Integrated Ocean Drilling Program Expedition 321 to measure sediment geochemical compositions at 2.5 cm resolution for the 450 m of the Site U1338 spliced sediment column. This sp

Pleistocene water cycle and eastern boundary current processes along the California continental margin

Autor: C. Ravelo, Dyke Andreasen, Annette Olivarez Lyle, Noah S. Diffenbaugh, Linda E. Heusser, Mitchell W Lyle

Publikováno v: Paleoceanography. 25

[1] Coastal marine sediments contain mixtures of terrestrial and marine paleoclimate proxies that record how the coastal water cycle has behaved over long time frames. We explore a 600 kyr marine record from ODP Site 1018, located due west of Santa C

Export productivity and carbonate accumulation in the Pacific Basin at the transition from a greenhouse to icehouse climate (late Eocene to early Oligocene)

Autor: Adina Paytan, Annette Olivarez-Lyle, Kristen Averyt, Michael Calhoun, Elizabeth M. Griffith, Andrea M. Erhardt, Mitch Lyle, Ellen Thomas, Timothy J. Bralower

Publikováno v: Paleoceanography. 25

[1] The late Eocene through earliest Oligocene (40–32 Ma) spans a major transition from greenhouse to icehouse climate, with net cooling and expansion of Antarctic glaciation shortly after the Eocene/Oligocene (E/O) boundary. We investigated the re

Pacific Ocean and Cenozoic evolution of climate

Autor: A. Christina Ravelo, David K. Rea, Timothy J. Bralower, Paul A. Wilson, Mitchell W Lyle, Annette Olivarez Lyle, Matthew Huber, John A. Barron

Publikováno v: Department of Earth, Atmospheric, and Planetary Sciences Faculty Publications

[1] The Pacific Ocean has played a major role in climate evolution throughout the Cenozoic (65–0 Ma). It is a fundamental component of global heat transport and circulation, the dominant locus of primary productivity, and, consequently, the largest

Eocene biogenic silica accumulation rates at the Pacific equatorial divergence zone

Autor: Richard D. Jarrard, Mitch Lyle, Theodore C. Moore, Annette Olivarez Lyle

Publikováno v: Paleoceanography. 23

[2] The Eocene biosiliceous oozes of the tropical Pacific are an easily recognizable sediment type having a reddish brown color and sugary texture. These sediments are dominated by radiolarian tests, with traces of terrigenous debris, hydrothermal ox

Missing organic carbon in Eocene marine sediments: Is metabolism the biological feedback that maintains end-member climates?

Autor: Annette Olivarez Lyle, Mitchell W Lyle

Publikováno v: Paleoceanography. 21

[1] Ocean chemistry is affected by pCO2 in the atmosphere by increasing the dissolution of solid calcium carbonate and elevating the dissolved inorganic carbon concentrations in seawater. Positive feedbacks between the ocean and atmosphere can mainta
