Quantitative Estimates of Younger Dryas Freshening From Lipid δ2H Analysis in the Beaufort Sea

Geophysical Research Letters, Volume 52, Issue 4, 28 February 2025.
Abstract The leading hypothesis attributes the Younger Dryas (YD) event to a disruption in the Atlantic Meridional Overturning Circulation, driven by meltwater input from North America. Determining the origin, timing, and magnitude of YD freshening are crucial for understanding abrupt climate change.

The generation and continued existence of overpressure in the Delaware Basin, Texas [PDF]

, 2007
The Delaware Basin, part of the larger Permian Basin, contains important hydrocarbon plays. Permian strata contain 71% of in-place oil and 53% of in-place gas, with the remainder hosted in the Lower Palaeozoic.

A 14,000‐Year Sediment Record of Mercury Accumulation and Isotopic Signatures From Lake Malaya Chabyda (Siberia)

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 10, October 2024.
Abstract Eurasian permafrost soils contain large amounts of organic carbon (OC) and mercury (Hg), sequestered by vegetation during past and present interglacial periods. Lake sediment archives may help understand past OC and Hg dynamics and how they interact with climate‐related variables.

The Silent VOICE—Searching for Geochemical Markers to Track the Impact of Late Jurassic Rift Tectonics

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 10, October 2024.
Abstract A causal mechanism for the Volgian Isotopic Carbon Excursion (VOICE) remains enigmatic. Elemental geochemical profiles of the Deer Bay Formation, Sverdrup Basin, Arctic Canada that record the VOICE and contemporaneous strata are herein examined to provide insight into depositional environments during Late Jurassic‐Early Cretaceous time.

The Distinct Composition and Transformation of Terrestrial Organic Carbon in the Yukon River Delta and Plume During the Mighty Spring Freshet

Journal of Geophysical Research: Biogeosciences, Volume 129, Issue 6, June 2024.
Abstract Arctic amplification is leading to increased terrestrial organic carbon (terrOC) mobilization with downstream impacts on riverine and marine biogeochemistry. To improve quantification and characterization of terrOC discharged to the Arctic Ocean, Yukon River delta samples were collected during three stages of the annual hydrograph (ascending ...

Hydrological Research Evolution: A Large Language Model‐Based Analysis of 310,000 Studies Published Globally Between 1980 and 2023

Water Resources Research, Volume 60, Issue 6, June 2024.
Abstract Hydrology plays a crucial role in understanding Earth's intricate water system and addressing water‐related problems, including against the backdrop of ongoing climate change. A retrospective review of the evolution of hydrology up to the current state of research is of great importance for understanding this role.

Numerical Reconstruction of Landslide Paleotsunami Using Geological Records in Alpine Lake Aiguebelette

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 5, May 2024.
Abstract Mass movements and delta collapses are significant sources of tsunamis in lacustrine environments, impacting human societies enormously. Paleotsunamis studies play an essential role in understanding historical events and their consequences, along with their return periods.

Depositional architecture and petroleum potential of the Cambro-Ordovician Hawaz Formation, Murzuq Basin, SW Libya. [PDF]

, 2006
The Murzuq Basin, SW Libya, contains a sedimentary fill up to 4000 m thick, comprising a marine Palaeozoic section and a continental Mesozoic section. The primary reservoir target in the basin is the Upper Ordovician Mamuniyat Formation, but where this ...

P- and S- wave velocities of consolidated sediments from a seafloor seismic survey in the North Celtic Sea Basin, offshore Ireland

, 2007
A geophysical survey was conducted over a hydrocarbon prospect in the North Celtic Sea Basin using a small array of ocean-bottom seismographs (OBSs). The purpose of this study was to determine the ratio of (P) compressional- to (S) shear-wave velocity of
