Prospects of multipurpose biomonitoring for fisheries assessment based on environmental nucleic acids

Journal of Fish Biology, EarlyView.
Abstract Methods using environmental nucleic acids have become highly effective for monitoring aquatic biodiversity, with an array of suitable use cases, including metrics for fisheries assessment. Traditional methods for assessing fish populations often rely on invasive techniques with limited spatial and temporal coverage.

Software for modelling and simulation of a Remotely-Operated Vehicle (ROV)

International Journal of Simulation Modelling, 2006
This paper considers the dynamic modelling and simulation of an underactuated Remotely Operated Vehicle (ROV) designed by Robotic Research Centre (RRC), in Nanyang Technological University (NTU) using a ROV Design and Analysis (RDA) toolbox written in MATLAB/SIMULINK™. The proposed RDA provides a means to simulate the mathematical models of ROV and the

Filter feeders living on suspension feeders: New insights into the lifestyle and distribution of Arcturidae Dana, 1849 (Crustacea: Isopoda) around Iceland

Marine Ecology, EarlyView.
Abstract The focus of the present study was on arcturid isopods occurring in the subarctic region around Iceland. Data from two decades of sampling with an epibenthic sledge (EBS) during numerous expeditions of the BIOICE (Benthic Invertebrates of Icelandic Waters; 1992–2004) and IceAGE (Icelandic marine Animals: Genetics and Ecology; 2011—ongoing ...

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...

Use of an ROV with Modulated Lighting for Diagnosing the Technical Condition of Submerged Port Wharf Structures [PDF]

TransNav
The technical condition of underwater port structures is critical to the safety and longevity of maritime infrastructure. Traditional inspection techniques, such as diver-assisted surveys, are constrained by safety risks, limited duration, and reduced ...
