The value of remote sensing techniques in supporting effective extrapolation across multiple marine spatial scales [PDF]

, 2017
The reporting of ecological phenomena and environmental status routinely required point observations, collected with traditional sampling approaches to be extrapolated to larger reporting scales.

Seafloor mapping based on multibeam echosounder bathymetry and backscatter data using Object-Based Image Analysis: a case study from the Rewal site, the Southern Baltic

Oceanological and Hydrobiological Studies, 2018
Seafloor mapping is a fast developing multidisciplinary branch of oceanology that combines geophysics, geostatistics, sedimentology and ecology. One of its objectives is to isolate distinct seabed features in a repeatable, fast and objective way, taking ...

Modelling the Effects of Wetland Restoration on Coastal Hydrology: A Case Study of Elkhorn Slough Watershed, California

Hydrological Processes, Volume 39, Issue 12, December 2025.
This study indicates that Hester Marsh, a restored site successfully maintains surface elevation, resulting in reduced surface inundation. The low‐lying Yampah Marsh, a reference site, is likely to be inundated due to future sea level rise (SLR) when the highest tides arrive, while a higher percentage of Hester Marsh would retain marsh vegetation in ...

Analyzing Archive Transit Multibeam Data for Nodule Occurrences

Journal of Marine Science and Engineering
We show that analyzing archived and future multibeam backscatter and bathymetry data, in tandem with regional environmental parameters, can help to identify polymetallic nodule fields in the world’s oceans.

An assessment of bottom current controlled sedimentation in Pacific Ocean abyssal environments [PDF]

, 2018
The effect of the circulation of polar-sourced dense waters on the deep seafloor is still largely unknown. This paper presents multibeam bathymetric evidence for the existence of present-day contourite drifts on the central Pacific ocean at depths ...

Multibeam bathymetry and CTD measurements in two fjord systems in southeastern Greenland

, 2017
. We present bathymetry and hydrological observations collected in the summer of 2014 from two fjord systems in southeastern Greenland with a multibeam sonar system. Our results provide a detailed bathymetric map of the fjord complex around the island of

A Possible Tsunamigenic Near‐Trench Strike‐Slip Fault, Offshore North Ecuador–South Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Seismic reflection and bathymetry collected along the Ecuador–Colombia obliquely convergent margin allow the first characterization of the NNE‐trending, near‐trench strike‐slip Ancon Fault in the possible source region of the 1906‐Mw8.6–8.8 and 1979‐Mw8.2 earthquakes, which produced devastating tsunamis.

Cyclic Pockmark Formation Linked to Plio‐Pleistocene Sea‐Level Rise on the Chatham Rise, New Zealand

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Pockmarks are geomorphological depressions on the seafloor in various underwater environmental settings. They are commonly linked to fluid release from subsurface reservoirs; however, the processes involved, fluid types, and relative timing of their formation often remain enigmatic.
