The new very small angle neutron scattering spectrometer at Laboratoire Leon Brillouin [PDF]

, 2007
The design and characteristics of the new very small angle neutron scattering spectrometer under construction at the Laboratoire Leon Brillouin is described. Its goal is to extend the range of scattering vectors magnitudes towards 2x10{-4} /A. The unique

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

Restoration 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

Frontiers 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.

The Impact of Acoustic Imaging Geometry on the Fidelity of Seabed Bathymetric Models [PDF]

, 2018
Attributes derived from digital bathymetric models (DBM) are a powerful means of analyzing seabed characteristics. Those models however are inherently constrained by the method of seabed sampling. Most bathymetric models are derived by collating a number

Inverse distance weighting method optimization in the process of digital terrain model creation based on data collected from a multibeam echosounder

Applied Geomatics, 2020
This paper presents the optimization of the inverse distance weighting method (IDW) in the process of creating a digital terrain model (DTM) of the seabed based on bathymetric data collected using a multibeam echosounder (MBES).

An Overview of Tsunami Hazards in the Southwest Pacific Ocean

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

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

Remote 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.

Data handling methods and target detection results for multibeam and sidescan data collected as part of the search for SwissAir Flight 111 [PDF]

, 1999
The crash of SwissAir Flight 111, off Nova Scotia in September 1998, triggered one of the largest seabed search surveys in Canadian history. The primary search tools used were sidescan sonars (both conventional and focussed types) and multibeam sonars ...

Frame Based Precoding in Satellite Communications: A Multicast Approach [PDF]

, 2014
In the present work, a multibeam satellite that employs aggressive frequency reuse towards increasing the offered throughput is considered. Focusing on the forward link, the goal is to employ multi-antenna signal processing techniques, namely linear ...

Magnetic Signature of Oceanic Transform Faults and Their Fracture Zones

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Oceanic transform faults (TFs) offset mid‐ocean ridges, juxtaposing different‐aged crust and causing fracture zones (FZ) crossing ocean basins. Mounting evidence challenges the consensus that TFs are conservative plate boundaries, instead supporting the existence of extensional tectonics and two phases of magmatism.
