Title: Tidal energy site resource assessment in the East River tidal strait, near Roosevelt Island, New York, New York

Abstract

This study demonstrates a site resource assessment to examine the temporal variation of the mean current, turbulence intensities, and power densities for a tidal energy site in the East River tidal strait. These variables were derived from two-months of acoustic Doppler velocimeter (ADV) measurements at the design hub height of the Verdant Power Gen5 hydrokinetic turbine. The study site is a tidal strait that exhibits semi-diurnal tidal current characteristics, with a mean horizontal current speed of 1.4 m s^-1, and turbulence intensity of 15% at a reference mean current of 2 m s^-1. Flood and ebb flow directions are nearly bi-directional, with higher current magnitude during flood tide, which skews the power production towards the flood tide period. The tidal hydrodynamics at the site are highly regular, as indicated by the tidal current time series that resembles a sinusoidal function. This study also shows that the theoretical force and power densities derived from the current measurements can significantly be influenced by the length of the time window used for averaging the current data. Furthermore, the theoretical power density at the site, derived from the current measurements, is one order of magnitude greater than that reported in the U.S. national resourcemore »« less

Performance Evaluation of HYCOM-GOM for Hydrokinetic Resource Assessment in the Florida Strait

Technical Report Neary, Vincent S ; Gunawan, Budi ; Ryou, Albert S

The U.S. Department of Energy (DoE) is assessing and mapping the potential off-shore ocean current hydrokinetic energy resources along the U.S. coastline, excluding tidal currents, to facilitate market penetration of water power technologies. This resource assessment includes information on the temporal and three-dimensional spatial distribution of the daily averaged power density, and the overall theoretical hydrokinetic energy production, based on modeled historical simulations spanning a 7-year period of record using HYCOM-GOM, an ocean current observation assimilation model that generates a spatially distributed three-dimensional representation of daily averaged horizontal current magnitude and direction time series from which power density time seriesmore »« less

Environmental Effects of Sediment Transport Alteration and Impacts on Protected Species: Edgartown Tidal Energy Project

Technical Report Barrett, Stephen B ; Schlezinger, David, Ph.D ; Cowles, Geoff, Ph.D ; ...

The Islands of Martha's Vineyard and Nantucket are separated from the Massachusetts mainland by Vineyard and Nantucket Sounds; water between the two islands flows through Muskeget Channel. The towns of Edgartown (on Martha's Vineyard) and Nantucket recognize that they are vulnerable to power supply interruptions due to their position at the end of the power grid, and due to sea level rise and other consequences of climate change. The tidal energy flowing through Muskeget Channel has been identified by the Electric Power Research Institute as the strongest tidal resource in Massachusetts waters. The Town of Edgartown proposes to develop anmore »« less

Multi-scale temporal patterns in fish presence in a high-velocity tidal channel

Journal Article Viehman, Haley A. ; Zydlewski, Gayle Barbin ; Hewitt, Judi - PLoS ONE

The natural variation of fish presence in high-velocity tidal channels is not well understood. A better understanding of fish use of these areas would aid in predicting fish interactions with marine hydrokinetic (MHK) devices, the effects of which are uncertain but of high concern. To characterize the patterns in fish presence at a tidal energy site in Cobscook Bay, Maine, we examined two years of hydroacoustic data continuously collected at the proposed depth of an MHK turbine with a bottom-mounted, side-looking echosounder. The maximum number of fish counted per hour ranged from hundreds in the early spring to over 1,000more »« less

Turbulence Measurements from Compliant Moorings. Part II: Motion Correction

Journal Article Kilcher, Levi F. ; Thomson, Jim ; Harding, Samuel ; ... - Journal of Atmospheric and Oceanic Technology

Acoustic Doppler velocimeters (ADVs) are a valuable tool for making high-precision measurements of turbulence, and moorings are a convenient and ubiquitous platform for making many kinds of measurements in the ocean. However, because of concerns that mooring motion can contaminate turbulence measurements and that acoustic Doppler profilers make middepth velocity measurements relatively easy, ADVs are not frequently deployed from moorings. This work demonstrates that inertial motion measurements can be used to reduce motion contamination from moored ADV velocity measurements. Three distinct mooring platforms were deployed in a tidal channel with inertial-motion-sensor-equipped ADVs. In each case, motion correction based on themore »« less

Tidal forcing of the water mass interface in the strait of Messina

Journal Article Hopkins, T S ; Salusti, E ; Settimi, D - J. Geophys. Res.; (United States)

The tidal currents of the Strait of Messina and their effect on the displacement of the water-mass interface are discussed utilizing the historical velocity data of Francesco Vercelli, taken from approx.100 anchor stations during 1922 and 1923. The data show a complex, strongly tidal behavior, in which speeds of 200-300 cm/s are attained over the sill. Messina is an amphidromic point for the tides of the two main basins of the Mediterranean Sea and two distinct water masses flow through the strait at different stages of the tide; the subsurface Laventine intermediate water flowing alternating with surface Tyrrhenian water flowingmore »« less
