Channelized melt flow in downwelling mantle: Implications for 226Ra-210Pb disequilibria in arc magmas [PDF]
, 2008 We present the results of an analytical model of porous flow of viscous melt into a steadily dilating ‘‘channel’’ (defined as a cluster of smaller veins) in downwelling subarc mantle.

Active Long-Lived Faults Emerging Along Slow-Spreading Mid-Ocean Ridges [PDF]
Oceanography, 2012 In the classic mid-ocean ridge model, new seafloor is generated through a combination of magmatic diking feeding lava flows at the spreading axis, and the formation of short-offset, high-angle normal faults that dip toward the axis.

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

A Common Origin for Ridge-and-Trough Terrain on Icy Satellites by Sluggish Lid Convection [PDF]
, 2015 Ridge-and-trough terrain is a common landform on outer Solar System icy satellites. Examples include Ganymede's grooved terrain, Europa's gray bands, Miranda's coronae, and several terrains on Enceladus.

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

The northern sector of the last British ice sheet : maximum extent and demise [PDF]
, 2008 Strongly divided opinion has led to competing, apparently contradictory, views on the timing, extent, flow configuration and decay mechanism of the last British Ice Sheet.

The Agulhas Ridge, South Atlantic: the peculiar structure of a fracture zone [PDF]
, 2005 The Agulhas Ridge is a prominent topographic feature that parallels the Agulhas-Falkland Fracture Zone (AFFZ). Seismic reflection and wide angle/refraction data have led to the classification of this feature as a transverse ridge.

Frontiers 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]
, 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.

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