Variability of Internally Generated Turbulence in an Estuary, from 100 Days of Continuous Observations [PDF]

, 2009
We present detailed observations of internally generated turbulence in a sheared, stratified natural flow, as well as an analysis of the external factors leading to its generation and temporal variability.

Numerical Assessments of Tidal Stream and Wave Energy in Coastal Shelf Seas

Journal of Marine Science and Engineering, 2022
Tidal stream and wave energy resources may have the potential to complement the exploitation of wind power currently promoted, in industrial countries, as one of the alternatives to fossil fuel energies [...]

Tidal stream energy resource assessment of the Anglesey Skerries [PDF]

International Journal of Marine Energy, 2013
Abstract Many candidate sites for tidal stream power devices can be classified as headlands. This paper analyses one such site, off Anglesey. In order to investigate the disturbance to the local flow field due to the operation of tidal arrays and evaluate the extractable power at the site, a two-dimensional depth-averaged shallow water model of the ...

Scenario Analysis of Cost-Effectiveness of Maintenance Strategies for Fixed Tidal Stream Turbines in the Atlantic Ocean

Journal of Marine Science and Engineering, 2023
This paper has developed an operation and maintenance (O&M) model for projected 20 MW tidal stream farm case studies at two sites in the northeast Atlantic in France and at EMEC’s Fall of Warness site in the UK.

The downstream wake response of marine current energy converters operating in shallow tidal flows

, 2011
This paper presents findings from an experimental study investigating the downstream wake response from marine current energy convertors operating in various degrees of vertical flow constraint. The paper investigates deep vertically unconstrained sites,

The Orbit of the Orphan Stream [PDF]

, 2010
We use recent SEGUE spectroscopy and SDSS and SEGUE imaging data to measure the sky position, distance, and radial velocities of stars in the tidal debris stream that is commonly referred to as the "Orphan Stream." We fit orbital parameters to the data ...

Assessment of the Malaysian Tidal Stream Energy Resources

IOP Conference Series: Materials Science and Engineering, 2019
Abstract As a developing country, Malaysia has shown great interest and effort to commit and invest for green technology and green energy especially tidal energy resources. This research project is conducted to carry out an assessment study to analyse and compare several locations in Malaysia while using the optimal analytical approach ...

Investigation of Low Order Parameters Affecting Tidal Stream Energy Resource Assessments

Proceedings of the European Wave and Tidal Energy Conference, 2023
Tidal stream energy may have the potential to contribute to the baseline energy needs of the UK. There is a significant difference between the existing assessments of the UK’s resource, highlighting the need for a standardised model. The paper investigates some challenges of quantifying tidal stream energy.

Using drifting passive echolocation loggers to study harbour porpoises in tidal-stream habitats

Endangered Species Research, 2013
Moored passive acoustic detectors (e.g. C-PODs) are widely used to study harbour porpoise Phocoena phocoena distribution and relative abundance, but their use in tidal-stream habitats is complicated by the need for retrievable flow-resistant seabed ...
