Geochemical Signatures of Paleoclimate Changes in the Sediment Cores from the Gloria and Snorri Drifts (Northwest Atlantic) over the Holocene-Mid Pleistocene

open access: yesGeosciences, 2019
A multiproxy study of the sediment cores taken from the Snorri Drift, formed under the influence of the Iceland−Scotland bottom contour current, and from the Gloria Drift, located southward Greenland at the boundary of Irminger and Labrador Seas ...

3‐D Seismic Investigation of a Gas Hydrate and Fluid Flow System on an Active Mid‐Ocean Ridge; Svyatogor Ridge, Fram Strait

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Tectonic settings play a large role in the development of fluid flow pathways for gas migrating through sedimentary strata. Gas hydrate systems worldwide are located on either the slopes of passive continental margins, often in large contourite deposits,

Progress in marine geoconservation in Scotland’s seas : assessment of key interests and their contribution to Marine Protected Area network planning [PDF]

open access: yes, 2016
This study was part-funded by Marine Scotland and was undertaken as part of the Scottish Marine Protected Areas (MPA) Programme, a joint initiative between Marine Scotland, Historic Scotland, Scottish Natural Heritage (SNH) and the Joint Nature ...

Detection and correction of inclination shallowing in deep sea sediments using the anisotropy of anhysteretic remanence [PDF]

open access: yes, 1993
Paleomagnetic data from recent Pleistocene to recent deep sea sediments from the continental rise of eastern North America exhibit a cyclical inclination shallowing, up to 30° with respect to the geocentric axial dipole value. This shallowing is strongly

The role of Internal Solitary Waves on deep-water sedimentary processes. The case of up-slope migrating sediment waves off the Messina Strait [PDF]

open access: yes, 2016
Subaqueous, asymmetric sand waves are typically observed in marine channel/canyon systems, tidal environments, and continental slopes exposed to strong currents, where they are formed by current shear resulting from a dominant unidirectional flow ...

Impact of Tectonic, Glacial and Contour Current Processes on the Late Cenozoic Sedimentary Development of the Southeast Greenland Margin

open access: yesGeosciences, 2019
To understand the geomorphological contrast between the northern and southern parts of the Southeast Greenland margin with its marked differences in sedimentary regime, bathymetric and seismic reflection, data have been compiled and analysed.

Role of tectonic stress in seepage evolution along the gas hydrate‐charged Vestnesa Ridge, Fram Strait [PDF]

open access: yes, 2015
Methane expulsion from the world ocean floor is a broadly observed phenomenon known to be episodic. Yet the processes that modulate seepage remain elusive.

Bolboforma from Leg 105, Labrador Sea and Baffin Bay, and the chronostratigraphy of Bolboforma in the North Atlantic [PDF]

open access: yes, 1989
The genus Bolboforma, first described by Daniels and Spiegler (1974), is a problematic group of calcareous microfossils. Solbaforma is most probably a planktonic cyst (Rogl and Hochuli, 1976) having protozoan or algal affinities (Poag and Karowe, 1986 ...

Bulk Mineralogy of Pleistocene Mediterranean Outflow Water Contourites at IODP Site 1387 [PDF]

open access: yes, 2015
Expedition 339 of the Integrated Ocean Drilling Program collected ocean sediment cores at seven localities in the Gulf of Cadiz and on the West Iberian margin, a contourite deposition system (CDS) influenced by the Mediterranean Outflow Water (MOW).

Recent contourites in the Alboran Sea

open access: yes, 2012
Critical reviews of the available seismic records and analyses of CTD data in the Alboran Sea have changed the previous interpretations about the types of deposits making up the nearsurface sediments of the Alboran Sea. During the last 20 years many studies about sedimentation in the Alboran Sea suggested that turbiditic fans, gravitative deposits and ...
