A Conceptual Framework and Methods for Studying the Connectivity of Fishes
Fish and Fisheries, Volume 27, Issue 2, Page 342-369, March 2026.ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Mapping and Characterizing Subtidal Oyster Reefs Using Acoustic Techniques, Underwater Videography and Quadrat Counts [PDF]
, 2003 Populations of the eastern oyster Crassostrea virginica have been in long-term decline in most areas. A major hindrance to effective oyster management has been lack of a methodology for accurately and economically obtaining data on their distribution and

The use of multibeam sonar mapping techniques to refine population estimates of the endangered white abalone (Haliotis sorenseni) [PDF]
, 2006 Multibeam sonar mapping techniques provide detailed benthic habitat information that can be combined with the data on species-specific habitat preferences to provide highly accurate calculations of populations in a particular area. The amount of suitable

Video imaging in turbid water [PDF]
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 ...

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

Sidescan Sonar Image Enchancement Using a Decomposition Based on Orthogonal Functions. Applications with Chebyshev Polynomials [PDF]
, 1991 A method is presented to remove from sidescan sonar images of the seafloor, artifacts that are clearly unrelated to the backscattering properties of the seafloor.

Method for shaping and aiming narrow beams [PDF]
, 1981 A sonar method and apparatus is discribed which utilizes a linear frequency chirp in a transmitter/receiver having a correlator to synthesize a narrow beamwidth pattern from otherwise broadbeam transducers when there is relative velocity between the ...
