EASTERN EQUATORIAL PACIFIC PRODUCTIVITY VIA TWO GEOCHEMICAL PROXIES
geochemistry nutrient cycling phosphorus
2015/1/16
Drivers that influence oceanic productivity are not clearly constrained. However, sea level changes during glacial cycles have been proposed as a potential driver for productivity variations observed ...
PALEOPRODUCTIVITY VARIATIONS IN THE EASTERN CENTRAL EQUATORIAL PACIFIC OCEAN ON GLACIAL TIMESCALES
Nutrients Phosphorus Cycle Glacial-Interglacial Sea Level
2015/1/16
Paleoproductivity records during the late Pleistocene are sparse. The equatorial Pacific and the Southern Ocean are collectively responsible for the majority of the new production in the oceans. The n...
Paleoceanography of the South China Sea and the western equatorial Pacific: Testing linkages between Indonesian Seaway closure and sea level change during the Middle to Late Miocene (～13--5 Ma)
Paleoceanography the equator the equator of the south China sea west Pacific sea level climate change
2014/10/22
The tectonic opening and closing of ocean gateways played a key role in global climate change during the Cenozoic. Although changes in these gateways affected ocean circulation and heat transport, man...
Enrichment of particulate phosphorus in a sea-surface microlayer over the Eastern Equatorial Pacific Ocean
sea-surface microlayer biogeochemical enrichment particulate phosphorus high-nutrient low-chlorophyll ocean
2017/4/11
The significant enrichment of chemical composition associated with enhanced bioactivities and an increased number
of bio-particles in the sea-surface microlayer (SML) were observed in the high-nutrie...
Contribution of picophytoplankton to carbon export in the equatorial Pacific: A reassessment of food web flux inferences from inverse models
Contribution of picophytoplankton equatorial Pacific
2014/4/17
The paradigm that carbon export is derived almost exclusively from the primary production of large
phytoplankton has been challenged by inverse ecosystem modeling studies that suggest that most carbo...
Increase in water column denitrification during the last deglaciation: the influence of oxygen demand in the eastern equatorial Pacific

Nitrogen uptake and regeneration pathways in the equatorial Pacific:a basin scale modeling study
Nitrogen uptake regeneration pathways equatorial Pacific basin scale modeling
2010/1/21
It is well known that most primary production is fueled by regenerated nitrogen in the open ocean. Therefore, studying the nitrogen cycle by focusing on uptake and regeneration pathways would advance ...
El Niño—The Dynamic Response of the Equatorial Pacific Ocean to Atmospheric Forcing
El Niñ o—The Dynamic Response Atmospheric Forcing Equatorial Pacific Ocean
2009/3/24
El Niño is the occasional appearance of warm water off the coast of Peru; its presence results in catastrophic consequences in the fishing industry. A new theory for the occurrence of El Ni&nti...
Regulation of phytoplankton carbon to chlorophyll ratio by light,nutrients and temperature in the Equatorial Pacific Ocean:a basin-scale model
phytoplankton carbon chlorophyll ratio Equatorial Pacific Ocean basin-scale model
2010/1/19
The complex effects of light, nutrients and temperature lead to a variable carbon to chlorophyll (C:Chl) ratio in phytoplankton cells. Using field data collected in the Equatorial Pacific, we derived ...
Changes in Thermal Structure of the Equatorial Pacific during the 1972 El Niño as Revealed by Bathythermograph Observations
Thermal Structure El Niñ o Equatorial Pacific Bathythermograph Observations
2009/2/8
Bathythermograph data from the equatorial Pacific are used to study changes in upper ocean thermal structure during the period 1971–73 using data averaged over 2- or 3-month segments. This gives reaso...
