Geometric and Radiometric Correction of Multibeam Backscatter Derived from Reson 8101 Systems [PDF]
, 2002 A common by-product of multibeam surveys is a measure of the backscattered acoustic intensity from the seafloor. These data are of immense interest to geologists and geoscientists since maps of the acoustic backscatter strength can be used to infer ...

The Seismic Expression of Core Complex‐Style Extensional Detachment Faults in Rifted Margins
Terra Nova, EarlyView.ABSTRACT The identification of core complex‐style extensional detachment faults (CCDFs) in rifted margins is crucial for accurately restoring their stratigraphic and thermal histories. Yet recognising CCDFs in seismic reflection images is challenging due to their faint topographic expression; the lack of associated abrupt offset in seismic reflections;

Emergence of Continents Stabilized the Bioavailability of Boron
Terra Nova, EarlyView.ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Special JGR‐B issue: Mapping the seafloor
Eos, Transactions American Geophysical Union, 1984 JGR‐B will publish a special issue in 1985 focusing on the results obtained by using a variety of new seafloor mapping tools (e.g., SEA BEAM, SEA MARC I and II, GLORIA, GEOS 3, and Seasat radar altimetry). Liberal use of color and large‐format black and white figures is encouraged. Special reduced rates for color will apply.

First AUV and ROV investigation of seismogenic faults in the Alboran Sea (Western Meditarranean) [PDF]
, 2016 In May-June 2015 we carried out the SHAKE cruise on board the RV “Sarmiento de Gamboa” the first in situ investigation using state-of-the-art underwater vehicles, the AUVs “AsterX” and “IdefX” (IFREMER, France) and the ROV “Max Rover” (HCMR, Greece ...

Zoologica Scripta, EarlyView.ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

UVSD: Software for Detection of Color Underwater Features [PDF]
, 2005 Underwater Video Spot Detector (UVSD) is a software package designed to analyze underwater video for continuous spatial measurements (path traveled, distance to the bottom, roughness of the surface etc.) Laser beams of known geometry are often used in ...

Modeling the Effect of Oceanic Internal Waves on the Accuracy of Multibeam Echosounders [PDF]
, 2010 When ray bending corrections are applied to multibeam echosounder (MBES) data, it is assumed that the varying layers of sound speed lie along horizontally stratified planes.

Satellite Measurements Make Major Seafloor Map Improvements
EosThough ship-based sounding has mapped some areas of the ocean floor in higher resolution, researchers have used SWOT data to create a detailed new map of the seafloor, including thousands of previously undetected small seamounts.

Real-time Monitoring of Uncertainty due to Refraction in Multibeam Echo Sounding [PDF]
, 2010 A software toolkit has been developed to objectively monitor uncertainty due to refraction in multibeam echosounding, specifically mapping systems that employ underway sound speed profiling hardware.
