Automated, objective texture segmentation of multibeam echosounder data - Seafloor survey and substrate maps from James Island to Ozette Lake, Washington Outer Coast [PDF]

open access: yes, 2007
Without knowledge of basic seafloor characteristics, the ability to address any number of critical marine and/or coastal management issues is diminished. For example, management and conservation of essential fish habitat (EFH), a requirement mandated by

Bridging Ecology and Geosciences in Riverscapes: Implications for Process‐Based Restoration

open access: yesEcological Research, Volume 41, Issue 1, January 2026.
In this paper, we synthesize studies that integrally examine geological and ecological processes across different scales and components of riverscapes, including geohydrological processes. Finally, we identify both scientific and practical challenges that must be addressed to bridge the gap between basic‐science implications and their implementation in

Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

open access: yesBoreas, Volume 55, Issue 1, Page 198-215, January 2026.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

Video imaging in turbid water [PDF]

open access: yes
In order to describe seabed habitats and to identify and quantify spatial patterns information is needed at different scales. Whereas ground-truthing techniques are used to gain point information, remote sensing techniques are used to obtain information ...
