Turbine sound may influence the metamorphosis behaviour of estuarine crab megalopae. [PDF]

open access: yesPLoS ONE, 2012
It is now widely accepted that a shift towards renewable energy production is needed in order to avoid further anthropogenically induced climate change. The ocean provides a largely untapped source of renewable energy.

Lifetime Analysis of IGBT Power Modules in Passively Cooled Tidal Turbine Converters

open access: yesEnergies, 2020
Thermal cycling is one of the major reasons for failure in power electronic converters. For submerged tidal turbine converters investigating this failure mode is critical in improving the reliability, and minimizing the cost of energy from tidal turbines.

Development of high performance composite bend-twist coupled blades for a horizontal axis tidal turbine

open access: yes, 2009
Development of a design methodology for a composite, bend-twist coupled, tidal turbine blade has been undertaken. Numerical modelling was used to predict the response of the main structural member for the adaptive blade.

Carrion ecology: concepts, interdisciplinary synthesis, and perspectives

open access: yesBiological Reviews, EarlyView.
ABSTRACT Carrion is a ubiquitous resource in both terrestrial and aquatic ecosystems, yet it has long been overlooked in ecological research. Over the past two decades, studies on carrion and the many organisms that exploit it have flourished, revealing not only wide‐ranging ecological functions but also significance far beyond ecology.

Unlocking Hydrokinetic Energy in the Brazilian Amazon: A Statistical Resource Assessment and Economic Feasibility Analysis

open access: yesEnergy Science &Engineering, EarlyView.
This study develops a spatial and technical framework to evaluate hydrokinetic energy potential in the Amazon as a sustainable alternative to diesel‐based systems. By modeling regional resources, we demonstrate that hydrokinetic sources offer a cleaner, economically competitive solution for displacing fossil fuels in remote riverine communities ...

Experimental Analysis and Evaluation of the Numerical Prediction of Wake Characteristics of Tidal Stream Turbine

open access: yesEnergies, 2017
It is important to understand tidal stream turbine performance and flow field, if tidal energy is to advance. The operating condition of a tidal stream turbine with a supporting structure has a significant impact on its performance and wake recovery. The

From Map Follower to Navigator: Archetypes of Environmental Impact Assessment

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT Environmental impact assessment (EIA) scholarship is commonly framed as a tension between efficiency and comprehensiveness paradigms. These paradigms describe a persistent tension but cannot explain how EIA operates through it. Drawing on social systems theory, this analysis traces that operation.
