Regional Variations in Sea Ice and Primary Productivity in the Bering Sea During Marine Isotope Stage 11

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Marine Isotope Stage (MIS) 11 (424–374 ka) has long been an analog for Holocene climate because it is the most recent interglacial period with similar orbital conditions. However, there is global and regional variability in the climate response to MIS 11 warmth.

Characterization of Deep-Water Submarine Fan Reservoir Architecture: AB120 Reservoir in the Campos Basin

open access: yesFrontiers in Earth Science, 2022
The exploration of deep-water submarine fan reservoirs has become a prominent research area for hydrocarbon discovery and recovery. However, the high operational costs render efficient exploration of this type of reservoir crucial, and the pivotal ...

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Laurasian Seaway History During the Early Jurassic From Quantitative Mineralogy and Detrital Zircon Dating

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Laurasian Seaway comprises a N‐S oriented trans‐Pangaean corridor linking Tethys to the Boreal Sea during the Jurassic, and direction of water flow has been the subject of considerable debate. The Llanbedr (Mochras Farm) borehole, Cardigan Bay Basin, Wales, is a uniquely informative record that comprises an expanded deep‐marine silty ...

Paleoceanography and ice sheet variability offshore Wilkes Land, Antarctica – Part 1: Insights from late Oligocene astronomically paced contourite sedimentation [PDF]

open access: yesClimate of the Past, 2018
Antarctic ice sheet and Southern Ocean paleoceanographic configurations during the late Oligocene are not well resolved. They are however important to understand the influence of high-latitude Southern Hemisphere feedbacks on global climate under CO2 ...

Seismic Stratigraphy of the Peruvian Forearc Drifts from 3° to 7°S: Identification and Influence of Lower Layers of the Humboldt Current System

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The seafloor morphology and subsurface geometry of a late Neogene contourite drift located along the Peru margin is documented for the first time using multibeam bathymetry, two‐dimensional and three‐dimensional seismic data. Along the margin several submarine canyons incise the shelf and slope.

Efficient Organic Carbon Burial by Bottom Currents in the Ocean: A Potential Role in Climate Modulation

open access: yesGeophysical Research Letters
Bottom currents play a major role in deep‐sea sedimentation, but their significance in the burial of organic carbon is poorly quantified at a global scale.

An Early Neogene—Early Quaternary Contourite Drift System on the SW Barents Sea Continental Margin, Norwegian Arctic

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The onset and evolution of the middle to late Cenozoic “icehouse” world was influenced by the development of the global ocean circulation linking the Norwegian–Greenland Sea‐Arctic Ocean to the Atlantic Ocean.

Palaeolandscape reconstruction of a shallow coastal embayment in Kattegat, Denmark—influence of sea‐level changes during the latest Pleistocene and Holocene

open access: yesBoreas, Volume 55, Issue 2, Page 560-584, April 2026.
We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

open access: yesSedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.
