Remote Sensing With Machine Learning to Monitor Seagrass Meadows: Long‐Term Trends in Tauranga Harbour, New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 3, September 2026.
Seagrass meadows play critical roles in coastal ecosystems by stabilising sediments, supporting biodiversity and sequestering carbon, yet monitoring their recovery at scale is often constrained by the lack of scalable and repeatable approaches. This study applies an open‐source remote‐sensing framework to track long‐term changes in Zostera muelleri in ...

Application of geometrical form factor in differential absorption lidar measurement

, 1997
The peak position for a lidar return signal is calculated and measured for the horizontal path with variation of the laser beam divergence angle (theta), and the inclination angle (delta) between the telescope and laser axes.

Exploring the Use and Impact of Composite Materials in Robotics: A Systematic Review

Journal of Field Robotics, Volume 43, Issue 6, Page 4037-4060, September 2026.
ABSTRACT Lightweight and high‐strength materials are important in robotics, as structural design impacts efficiency, payload capacity, and energy consumption. Composite materials, with their superior stiffness‐to‐weight ratios and multifunctional properties, offer clear advantages over conventional metals and polymers.

Characterizing the Distribution of Nepheloid Layers and Their Response to Hydrodynamics in the NE Rockall Trough, NE Atlantic Ocean

Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.
Abstract Suspended and slow‐sinking particles, especially those concentrated within nepheloid layers, can act as pivotal mediators of oceanic carbon transport and benthic‐pelagic coupling. However, identifying nepheloid layers and distinguishing their composition (i.e., inorganic particles, phytoplankton, zooplankton, and fish) using only acoustic ...

Ferric Chloride: The Venusian Unknown UV Absorber?

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.

Hydrodynamic and Sediment Response to Oyster Castles Under Wave Forcing: Insights From Laboratory Flume Experiments

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Nature‐based shoreline protection strategies, such as engineered oyster reefs and living shorelines, offer sustainable alternatives to hard infrastructure. In this controlled laboratory study, we evaluate relative hydrodynamic and sediment‐response differences among interlocking oyster‐castle configurations under monochromatic wave forcing ...

Inside the Fire Plume Chemical Interactions: A Review on Key Processes and Future Directions

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Fire plumes are rising columns of heated air masses, consisting of gaseous and particulate matter generated by combustion, affecting air quality, climate and public health. The chemical species released undergo secondary reactions and participate in chemical and physical interactions, altering the properties of the fire plume.
