Enhancing macrophyte sub-classification through neighborhood-independent full-waveform LiDAR

ISPRS Open Journal of Photogrammetry and Remote Sensing
In the clear, shallow waters of the littoral zone, bathymetric LiDAR, SONAR, and photogrammetry have proven suitable for mapping both the underwater landscape and vegetation. In the past, all three methods have been used to map underwater vegetation, but

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Satellite‐Derived Volume Budget of Antarctic Sea Ice

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In recent years, the Antarctic has seen a notable shift in sea ice trends: Where sea ice extent and volume were increasing on average, they have shown an unprecedented decline since 2016. Understanding the drivers of this shift is crucial to determining the impacts of climate change on sea ice and improving modeling of Antarctic sea ice ...
