Event Deposits Recorded Over the Past 800 kyr in IODP Hole U1433A (South China Sea): Implications of a Revised Methodology for Chronology and Paleoclimate Reconstruction

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract Instantaneous event deposits such as turbidites, debrites, and slumps are common and frequently occur in marginal seas. These instantaneous deposits represent seconds to days in duration, and can therefore significantly impact age‐depth models and interpretation of paleoclimate history based on thick sedimentary sequences recovered in deep ...

Seismic Characteristics of the Gas Hydrate System in the Mackenzie Trough of the Canadian Beaufort Sea, Arctic Ocean

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract We present a comprehensive seismic characterization of the gas hydrate system in the outer continental shelf of the Mackenzie Trough, Canadian Beaufort Sea, based on recently acquired multichannel seismic (MCS) data, P‐wave velocity modeling, and 3D thermal modeling. We identified high‐amplitude, reverse‐polarity Bottom‐Simulating Reflections (

Assessment of Short-Term Sediment Deposition Patterns Along the Palamós Submarine Canyon (NW Mediterranean) Using ²³⁴Th

Journal of Marine Science and Engineering
Sedimentary dynamics in the Palamós Canyon are influenced by river inputs and storm resuspension, as well as by bottom trawling on the canyon flanks. In this study, we estimate recent sediment deposition patterns along the canyon axis using the excess ...

Effectiveness of conservation lands in Mexico for safeguarding terrestrial endemic species from the human‐induced extinction crisis

Conservation Science and Practice, Volume 8, Issue 8, August 2026.
Across 1639 endemic Mexican species, we show that most species' ranges coincide with moderate to high human pressure, while existing conservation lands cover only a small fraction of their distributions. This spatial mismatch indicates that current conservation–land networks are insufficient to prevent future biodiversity loss. Substantial expansion of

Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

Journal of Anatomy, Volume 249, Issue 2, Page 264-291, August 2026.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.

Evidence of a local BCC‐type coordination of cobalt in FCC taenite of iron meteorites

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1861-1874, August 2026.
Abstract Ni, Co, and Fe K‐edge X‐ray absorption fine structure (XAFS) measurements were performed, revealing an unexpected local structure around Co in well‐known iron and stony‐iron meteorites. Cobalt is enriched in kamacite but remains in taenite at concentrations of at least 0.3 atom%.

Cascades in Mediterranean submarine grand canyons

Oceanography, 2009
Continuous monitoring of water-column and near-bottom hydrosedimentary processes in the Mediterranean Sea over the last 15 years has resulted in a novel view of the functioning of this land-locked sea. Destratification of the water column and fast, dense, organic-matter-rich, and sediment-laden near-bottom currents occurring in late winter to early ...

Channeling Action: How Civic Recreation Organizations Shape Civic Capacity and Engagement

Politics &Policy, Volume 54, Issue 4, August 2026.
ABSTRACT In this paper, we examine the individual‐level and organizational‐level implications of participation in a particular type of civic association—a civic recreation organization. We deploy a small‐n comparison group design, comparing data within and across members of a civic recreation organization with varying degrees of involvement to ...

Sediment transport and depositional hydrodynamics on the eastern Korean continental margin revealed by surface sediment granulometry

Sedimentology, Volume 73, Issue 5, Page 1469-1487, August 2026.
ABSTRACT Terrigenous sediments are transported from coastal areas and shelves to deeper continental margins by multiple processes. Understanding these processes is critical for evaluating the ecological impacts of fine‐grained sediment deposition and predicting future changes in sediment dispersal under rapid climate change.
