Advancements in CARIS SIPS backscatter and seabed classification

open access: yes, 2017
Following the public release of SIPS Backscatter, a new algorithm for processing multibeam backscatter imagery, Teledyne CARIS has continued investment in this approach to provide reliable backscatter mosaics that can be used to support a variety of seabed mapping tasks.

Functionally Rich Fish Assemblages Support Greater Rates of Multiple Ecological Functions in Seagrass Meadows

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We show that the functional diversity of fishes promotes multifunctionality in seagrass meadows. We found that there was consistency in the seascape context and connectivity variables that structured the rate and distribution of different components of functioning and the functional diversity of fish in seagrass meadows.

Physics-Guided Random Forest Classification of Marine Sediments Using Frequency-Dependent Acoustic Reflection Spectra

open access: yesApplied Sciences
Traditional acoustic seabed classification methods, which are often sensitive to survey geometry and environmental conditions, have limitations in reliability and reproducibility.

Tsunami Casualty Risk Assessment Integrating Evacuation Tower Placement, Seismic Road Network Performance Enhancement, and Disaster Education

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 500-520, February 2026.
ABSTRACT Since the 2011 Great East Japan earthquake, tsunami evacuation towers have been constructed in coastal regions based on worst‐case predictions to provide additional safety margins against unprecedented tsunamis. However, the extent to which such assumptions effectively reduce casualty risk remains unclear.

A regional seabed geomorphological map over part of the southwestern pacific plate

open access: yesJournal of Maps
We use the GEBCO global bathymetric product alongside other data sets, including magnetic anomaly and vertical gravity gradient, to interpret the seabed geomorphology of approximately 24.7 million km2 of the southwestern Pacific Plate at an effective ...

Site Selection of Onshore Wind and Solar Farms With Hydrogen Energy Storage: A Review

open access: yesEnergy Storage, Volume 8, Issue 1, February 2026.
ABSTRACT Onshore wind farms (OWF) and onshore solar farms (OSF) are essential to the global transition to renewable energy. Their complementary generation patterns enhance power supply stability and improve grid reliability. Co‐located projects can optimize land use and share infrastructure, reducing costs while increasing efficiency.

Tectonics as a Regulator of Shoreline Retreat and Rocky Coast Evolution Across Timescales

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract Rocky coast morphology is shaped by interactions between wave action, sea level, and tectonics over millennial time scales. However, a clear and quantifiable signature of tectonic uplift on decadal to centennial shoreline retreat rates is outstanding.

Active Transport of Carbon to Demersal Fish Communities in Shelf‐Slope‐Abyssal Systems of the North Atlantic Ocean

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The biological carbon pump sequesters carbon through passive fluxes of biologically derived carbon, and by active vertical movement of marine organisms. Trophic coupling between pelagic and benthic communities increases the efficiency of the biological carbon pump as less carbon is lost to remineralization.

On Importance of Acoustic Backscatter Corrections for Texture-based Seafloor Characterization [PDF]

open access: yes, 2012
Seafloor segmentation and characterization based on local textural properties of acoustic backscatter has been a subject of research since 1980s due to the highly textured appearance of sonar images. The approach consists of subdivision of sonar image in
