Radiocarbon constraints on the extent and evolution of the South Pacific glacial carbon pool

open access: yesNature Communications, 2016
On glacial/interglacial timescales CO2 might have been sequestered from the atmosphere and stored within the deep ocean. Here, the authors show that an old and CO2-rich water mass occupied the glacial South Pacific between ∼2,000 and 4,300 m water depth ...

Seismic stratigraphy and history of deep circulation and sediment drift development in Baffin Bay and the Labrador Sea [PDF]

open access: yes, 1989
Drilling results and seismic-reflection records at and across Ocean Drilling Program (ODP) Sites 645 (western Baffin Bay), 646, and 647 (Labrador Sea) provide important constraints on the history of deep-water circulation and sedimentation in response to

Hydrothermal Discharge During Submarine Eruptions: The Importance of Detection, Response, and New Technology [PDF]

open access: yesOceanography, 2012
Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to ...

Evidence for a reducing Archean ambient mantle and its effects on the carbon cycle [PDF]

open access: yes, 2016
Chemical reduction-oxidation mechanisms within mantle rocks link to the terrestrial carbon cycle by influencing the depth at which magmas can form, their composition, and ultimately the chemistry of gases released into the atmosphere.

Connectivity and divergence of symbiotic bacteria of deep-sea hydrothermal vent mussels in relation to the structure and dynamics of mid-ocean ridges

open access: yesFrontiers in Marine Science, 2022
The population divergence process of deep-sea vent invertebrates is driven by both biotic (e.g., dispersal during the larval stage) and abiotic factors such as deep-ocean currents, depth, and the geological setting of vents.

Multilingual lexicon of undersea features [PDF]

open access: yes, 2005
The department prepares a multilingual lexicon of undersea feature types with the purpose to make information on configuration of the seafloor and undersea feature types available for the general public interested in geographical sciences.

Petrological systematics of mid-ocean ridge basalts: Constraints on melt generation beneath ocean ridges [PDF]

open access: yes, 1992
Mid-ocean ridge basalts (MORB) are a consequence of pressure-release melting beneath ocean ridges, and contain much information concerning melt formation, melt migration and heterogeneity within the upper mantle.

Deformation-related volcanism in the Pacific Ocean linked to the Hawaiian-Emperor bend [PDF]

open access: yes, 2015
Ocean islands, seamounts and volcanic ridges are thought to form above mantle plumes. Yet, this mechanism cannot explain many volcanic features on the Pacific Ocean floor and some might instead be caused by cracks in the oceanic crust linked to the ...

Application of PXRF in sediment analysis for geochemical prospecting in Dragon Horn area on the southwestern Indian Ridge

open access: yes地质科技通报, 2022
Polymetallic sulfides associated with hydrothermal activity near the mid-ocean ridges are importantpotential replacement resources in the future, while their exploration techniques and methods are relatively scarce at present.
