Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Wideband, modular Diver Detection Sonar (DDS) [PDF]

open access: yes, 2010
The complete protection of naval harbours, port approaches and anchorages requires the underwater continuous monitoring and threat detection such as divers, their delivery vehicles or AUVs from safe distances. R&D Marine Technology Centre (CTM) has began

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Multi-Beam Sonar Application on Autonomous Underwater Robot

open access: yes, 2015
Autonomous underwater robots have more outstanding benefits than research ships for benthonic detection. A key problem is how to better use the detection senor on the robot, such as the multi-beam sonar.

Echoes of Intelligence: What AI Could Learn From Bats

open access: yesApplied AI Letters, Volume 8, Issue 1, February 2027.
Bat biosonar offers a promising model for embodied AI: navigating dense vegetation through active perception and learning from sparse echoes suggests robust, parsimonious, autonomous alternatives to conventional vision‐centered, data‐intensive systems.

Evaluation of fine fescue taxa for sod production: Tensile strength, harvest timing, and comparisons to conventional cool‐season species

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Sod is an important specialty crop used to establish turfgrass and to control soil erosion in new construction and roadsides. Most sod farms in the northern U.S. grow Kentucky bluegrass (Poa pratensis L.), but recent research indicates potential for growing various low‐input grasses, such as fine fescue taxa (Festuca L. spp.).

Improving Protection Agains Intruders Using Passive Sonar

open access: yes, 2011
Divers and small vessels are increasingly recognized as a potential threat to high value assets. Harbour and waterside surveillance systems that are used to counter the threat of divers are usually based on active sonar, whose performance can be limited ...
