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...
Studies on the Indo-Pacific Tridacnidae (Tridacna maxima) from the Northern Red Sea, Egypt
Tridacna Maxima Studies Red Sea Egypt
2012/11/29
In Egypt, Tridacna Maxima are found in Gulf of Suez, Gulf of Aqaba and Red Sea. Tridacna Maxima are very important ecological species as seafood source and as a substrate for reef-associated organisms...
Changes in Tropical Cyclone Number in the Western North Pacific in a Warming Environment as Implied by Classical Thermodynamics
Second Law of Thermodynamics Global Warming Thermal Wind Relation Sea Surface Temperature
2011/2/24
Observational analyses show that the equatorial trough in the western North Pacific (WNP) is a well-known origin for tropical cyclones (TC) which have tended to weaken in intensity and decrease in num...
Increase in water column denitrification during the last deglaciation: the influence of oxygen demand in the eastern equatorial Pacific
water column denitrification the last deglaciation oxygen demand the eastern equatorial Pacific
2010/1/4
Here we present organic export production and nitrogen isotope results spanning the last 30 000 years from a core recovered off Costa Rica (Ocean Drilling Program (ODP) Site 1242) on the leading edge ...

Nitrogen uptake and regeneration pathways in the equatorial Pacific:a basin scale modeling study
Nitrogen uptake regeneration pathways equatorial Pacific basin scale modeling
2009/11/24
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 ...
Oxygen penetration deep into the sediment of the South Pacific gyre
Oxygen penetration sediment South Pacific gyre
2009/8/7
Sediment oxygen concentration profiles and benthic microbial oxygen consumption rates were investigated during an IODP site survey in the South Pacific Gyre. Primary production, particle fluxes and se...
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
2009/3/17
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 ...
Anthropogenic carbon distribution in the eastern South Pacific Ocean
Anthropogenic carbon distribution eastern South Pacific Ocean
2009/2/6
We present results of the CO2/carbonate system from the BIOSOPE cruise in the Eastern South Pacific Ocean, in an area not sampled previously. In particular, we present estimates of the anthropogenic c...
Spatial and temporal variations in dissolved and particulate organic nitrogen in the equatorial Pacific:biological and physical influences
Spatial and temporal variations organic nitrogen equatorial Pacific
2008/12/11
To quote Libby and Wheeler (1997), "we have only a cursory knowledge of the distributions of dissolved and particulate organic nitrogen" in the equatorial Pacific. A decade later, we are still in need...
North Pacific-wide spreading of isotopically heavy nitrogen during the last deglaciation:Evidence from the western Pacific
North Pacific-wide spreading isotopically heavy nitrogen Pacific
2008/12/6
Sedimentary δ15 N records in two IMAGES cores (MD012404 and MD012403) retrieved from the Okinawa Trough (OT) in the western North Pacific reveal deglacial increases with two peaks occurring during the...
Distribution and fluxes of aggregates >100 μm in the upper kilometer of the South-Eastern Pacific
Distribution fluxes aggregates >100 μm upper kilometer South-Eastern Pacific
2008/9/29
Large sinking particles transport organic and inorganic matter into the deeper layers of the oceans. Between 70 and 90% of the aggregates exported from the surface mixed layer are disaggregated within...
Effects of storms on primary productivity and air-sea CO2 exchange in the subarctic western North Pacific:a modeling study
storms primary productivity air-sea CO2 exchange North Pacific
2008/8/27
Biogeochemical responses of the open ocean to storms and their feedback to climate are still poorly understood. Using a marine ecosystem model, we examined biogeochemical responses to the storms in th...
