Tributary‐scale oyster reef restoration in Harris Creek, Maryland: lessons from a decade of planning, implementing, and monitoring

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction In response to the decline of eastern oyster (Crassostrea virginica) populations in Chesapeake Bay, a large‐scale restoration initiative was launched in Harris Creek, Maryland, in 2011. This effort marked a shift from fragmented projects toward a coordinated, sanctuary‐based approach to oyster restoration.

Acoustic evidence of hydrocarbon release associated with the Spitsbergen Transform Fault, north of the Molloy Ridge, Fram Strait

open access: yesFrontiers in Earth Science
Hydrocarbon gases formed from biotic and abiotic processes are released through the seafloor at different locations around the world. They have been widely observed directly in video and photo data, and indirectly on echosounder data.

An Active Beam‐Reconfigurable Retrodirective Array

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
The proposed beam‐reconfigurable retrodirective array not only enables retroreflection toward the signal source but also achieves flexible beam steering via a tunable reflection plate, offering a viable solution for real‐time multipoint communication and multitarget wireless power transfer.

Multibeam Characteristics of a Negative Refractive Index Shaped Lens

open access: yesSensors, 2020
Narrow beam width, higher gain and multibeam characteristics are demanded in 5G technology. Array antennas that are utilized in the existing mobile base stations have many drawbacks when operating at upper 5G frequency bands. For example, due to the high

Variability of Natural Methane Bubble Release at Southern Hydrate Ridge

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Current estimations of seabed methane release into the ocean (0.4–48 Tg yr−1) are based on short‐term observations and implicitly assume that fluxes are constant over time.

Generative Semantic Communication for Efficient Utilization of Satellite Resources in 6G

open access: yesInternational Journal of Satellite Communications and Networking, Volume 44, Issue 4, Page 368-377, July/August 2026.
ABSTRACT In this paper, a two‐stage resource allocation framework is proposed for generative semantic communication (GSC)–enabled multibeam satellite systems. By integrating semantic compression and generative artificial intelligence, GSC enables efficient downlink transmission by allowing users to reconstruct content from compressed semantic prompts ...

Reconstructing Multibeam Echosounder Bathymetry with Generative Adversarial Networks: Toward Efficient Use of Survey Resources [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The spatial accuracy and resolution of Multibeam Echosounder data are inherently lower than those of high-resolution underwater LiDAR measurements. However, while Multibeam Echosounder provides wide coverage and extensive historical availability, LiDAR ...

Harmonizing Multi-Source Sonar Backscatter Datasets for Seabed Mapping Using Bulk Shift Approaches

open access: yesRemote Sensing, 2020
The development of multibeam echosounders (MBES) as a seabed mapping tool has resulted in the widespread uptake of backscatter intensity as an indicator of seabed substrate properties.
