Enhanced ventilation of Eastern North Atlantic Oxygen Minimum Zone with deglacial slowdown of Meridional Overturning [PDF]
The eastern Tropical North Atlantic Oxygen Minimum Zone (ETNA OMZ) plays a critical role in marine ecosystems off northwestern Africa. One of the key controls of the ETNA OMZ is ventilation driven by the subsurface ocean circulation of the Atlantic ...

Mass exchange between geophysical flows and beds: Idealised computational modelling using a Herschel-Bulkley rheology [PDF]
A key mechanism by which geophysical flows evolve is mass exchange with the underlying bed, either by entraining material from the bed, or by depositing material.

Sediment export in marly badland catchments modulated by frost-cracking intensity, Draix–Bléone Critical Zone Observatory, SE France [PDF]
At the interface between the lithosphere and the atmosphere, the critical zone records the complex interactions between erosion, climate, geologic substrate, and life and can be directly monitored.

Elevation-dependent trends in extreme snowfall in the French Alps from 1959 to 2019 [PDF]
Climate change projections indicate that extreme snowfall is expected to increase in cold areas, i.e., at high latitudes and/or high elevation, and to decrease in warmer areas, i.e., at mid-latitudes and low elevation.

A non-stationary extreme-value approach for climate projection ensembles: application to snow loads in the French Alps [PDF]
Anticipating risks related to climate extremes often relies on the quantification of large return levels (values exceeded with small probability) from climate projection ensembles. Current approaches based on multi-model ensembles (MMEs) usually estimate

Triggering and propagation of exogenous sediment pulses in mountain channels: insights from flume experiments with seismic monitoring [PDF]
In the upper part of mountain river catchments, large amounts of loose debris produced by mass-wasting processes can accumulate at the base of slopes and cliffs.

Keynote lecture. Defining Protection Works Against Debris-Flow Hazards: Industrial Standard, Tailor-made or Haute-couture? [PDF]
Despite centuries of forestry and empirical soil conservation works as well as decades of research on debris flow processes, defining protection strategies against debris flows remains complicated.

Space techniques based on GPS and SAR interferometry allow measuring millimetric ground deformations. Achieving such accuracy means removing atmospheric anomalies that frequently affect volcanic areas by modeling the tropospheric delays.

Non-stationary extreme value analysis of ground snow loads in the French Alps: a comparison with building standards [PDF]
In a context of climate change, trends in extreme snow loads need to be determined to minimize the risk of structure collapse. We study trends in 50-year return levels of ground snow load (GSL) using non-stationary extreme value models.

Open check dams and large wood: head losses and release conditions [PDF]
Open check dams are strategic structures to control sediment and large-wood transport during extreme flood events in steep streams and piedmont rivers.
