Acoustic evidence for topographic blocking on a steep submarine canyon wall

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Diel vertical migration (DVM) is the largest mass‐movement of animals on Earth, with profound ecological and biogeochemical consequences. DVM has mostly been studied in the open ocean; however, at steep slopes, pelagic animals including vertical migrators must contend with the seafloor, emphasizing the importance of understanding DVM in these ...

Performance of a glider‐mounted multifrequency echosounder for measuring the vertical distribution and abundance of large pelagic copepods

Limnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

River Research and Applications, Volume 42, Issue 5, Page 1054-1068, June 2026.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.

Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

Surface and Interface Analysis, Volume 58, Issue 6, Page 387-399, June 2026.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...
