The role of tree traits in explaining throughfall variability in US forests

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Throughfall, precipitation that passes through the plant canopy or drips from canopy surfaces, represents the dominant input of water to most forests and is extremely spatially and temporally variable. Many plant traits can influence throughfall, but because measuring throughfall and a wide variety of plant traits is labor intensive, most ...

Evaluation of the Accuracy of Bathymetry on the Nearshore Coastlines of Western Korea from Satellite Altimetry, Multi-Beam, and Airborne Bathymetric LiDAR

open access: yesSensors, 2018
Bathymetric mapping is traditionally implemented using shipborne single-beam, multi-beam, and side-scan sonar sensors. Procuring bathymetric data near coastlines using shipborne sensors is difficult, however, this type of data is important for maritime ...

Observations of coastal cliff landslide runout in southern California from 21 years of data

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Runout distance from coastal cliff landslides along the coast of northern San Diego County, California USA between 2001 and 2023 were mapped and quantified. Results indicated cliff height influenced runout distance, and that 98% of maximum runout distances were less than half the cliff height.

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

Sensory Morphology of Geodorcus helmsi (Coleoptera: Lucanidae) and its Relevance to the Conservation of New Zealand Stag Beetles

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Insects use sensilla to detect chemical and physical stimuli, mediating behaviours such as mate finding, foraging and mechanosensory responses. The distribution and density of sensilla can be examined using scanning electron microscopy. Investigating these structures can help elucidate rarely observed behaviours (e.g. mate finding and foraging).

Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

On the INS and GPS Data Processing for Airborne Gravity Applications

open access: yes
Airborne gravimetric and altimetric measurements depend heavily on the determination of the instantaneous position and attitude of the aircraft. Here, a methodology to process raw inertial data together with GPS data collected from at least two antennas ...

A comparison of stable platform and strapdown airborne gravity

open access: yes, 2000
To date, operational airborne gravity results have been obtained using either a damped two-axis stable platform gravimeter system such as the LaCoste and Romberg (LCR) S-model marine gravimeter or a strapdown inertial navigation system (INS), showing ...

Aerial and Space‐Borne Seismology on Venus: Viability and Design Implications for Future Missions

open access: yesEarth and Space Science, Volume 13, Issue 6, June 2026.
Abstract Venus' evolution remains a mystery because of the lack of in situ geophysical data to constrain its interior structure. Recently‐selected planetary missions VERITAS (NASA), DAVINCI+ (NASA), and EnVision (ESA) will investigate the planet's interior, surface, and atmospheric chemistry.
