Enhancing event stratigraphic correlations in the ultra‐deep Japan Trench using XRF‐CS cluster‐based chemostratigraphy

The Depositional Record, Volume 12, Issue 1, February 2026.
Cluster‐based chemostratigraphy using XRF‐CS enables high‐resolution correlation of event deposits across contrasting depositional settings in the Japan Trench. This approach reveals previously unrecognised events and compositional heterogeneity, offering new insights into sediment provenance and earthquake‐triggered deposition, with implications for ...

Independent statistical validation of the New Zealand Seafloor Community Classification

Aquatic Conservation: Marine and Freshwater Ecosystems
Abstract The New Zealand Seafloor Community Classification (NZSCC) is a national‐scale numerical community classification which depicts compositional turnover of 1716 taxa (demersal fish, reef fish, benthic invertebrates and macroalgae) classified into 75 groups representing seafloor communities.

Differentiating hyperpycnal, hypopycnal and turbidity current deposits in late Quaternary glaciogenic mud

The Depositional Record, Volume 12, Issue 1, February 2026.
X‐ray CT and microscopic analysis of glaciogenic mud provide insight into the deposits of sediment‐laden density flows and reveal that strata comprise two microtextural motifs. The deposits of bottom‐hugging hyperpycnal flows and slope‐failure‐related turbidity currents are characterised by laterally continuous, sharply bounded silt‐rich and clay‐rich ...

Taking machine learning with a grain of sand: Sediment Analysis Neural‐network Data‐engine (SAND‐e) reveals sedimentological differences between turbid and clear‐water reefs

The Depositional Record, Volume 12, Issue 1, February 2026.
Using machine learning, researchers can count and crudely identify sand grains from coral reefs automatically. This will allow us to generate larger datasets to answer sedimentological questions. Abstract Sediment is an important facet of sand cay reefs as it is responsible for reef accretion and island formation, with shifts in the proportions of ...

A bioregional classification of the continental shelf of northeastern North America for conservation analysis and planning based on representation [PDF]

, 2007
Understanding how well National Marine Sanctuaries and other marine protected areas represent the diversity of species present within and among the biogeographic regions where they occur is essential for assessing their conservation value and ...

Tsunami Casualty Risk Assessment Integrating Evacuation Tower Placement, Seismic Road Network Performance Enhancement, and Disaster Education

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 500-520, February 2026.
ABSTRACT Since the 2011 Great East Japan earthquake, tsunami evacuation towers have been constructed in coastal regions based on worst‐case predictions to provide additional safety margins against unprecedented tsunamis. However, the extent to which such assumptions effectively reduce casualty risk remains unclear.

Marine lebensspuren: improving the classification of seafloor traces from underwater imagery and observations

Frontiers in Marine Science
Taxonomy is a dynamic and evolving scientific field in biological and paleontological research, which describes and systematises species and other taxa and thus lays the foundation to solve and structure biological questions.

The influence of multiple stressors on the spatial distribution of corals

People and Nature, Volume 8, Issue 2, Page 342-358, February 2026.
Abstract Coral reef ecosystems are widely threatened by global change, yet the cumulative impacts of multiple interacting stressors remain difficult to quantify over space and time. We evaluate how long‐term artisanal fishing effort, blast fishing, human population density and marine protected areas (MPAs) interact with biophysical and seascape ...
