Wind Resource Assessment: San Nicolas Island, California


Book Description

San Nicolas Island (SNI) is the site of the Navy Range Instrumentation Test Site which relies on an isolated diesel-powered grid for its energy needs. The island is located in the Pacific Ocean 85 miles southwest of Los Angeles, California and 65 miles south of the Naval Air Weapons Station (NAWS), Point Mugu, California. SNI is situated on the continental shelf at latitude N33[degree]14' and longitude W119[degree]27'. It is approximately 9 miles long and 3.6 miles wide and encompasses an area of 13,370 acres of land owned by the Navy in fee title. Winds on San Nicolas are prevailingly northwest and are strong most of the year. The average wind speed is 7.2 m/s (14 knots) and seasonal variation is small. The windiest months, March through July, have wind speeds averaging 8.2 m/s (16 knots). The least windy months, August through February, have wind speeds averaging 6.2 m/s (12 knots).







Hybrid Energy System Cost Analysis: San Nicolas Island, California


Book Description

This report analyzes the local wind resource and evaluates the costs and benefits of supplementing the current diesel-powered energy system on San Nicolas Island, California (SNI), with wind turbines. In Section 2.0 the SNI site, naval operations, and current energy system are described, as are the data collection and analysis procedures. Section 3.0 summarizes the wind resource data and analyses that were presented in NREL/TP 442-20231. Sections 4.0 and 5.0 present the conceptual design and cost analysis of a hybrid wind and diesel energy system on SNI, with conclusions following in Section 6. Appendix A presents summary pages of the hybrid system spreadsheet model, and Appendix B contains input and output files for the HYBRID2 program.




Cost Analysis of San Nicolas Island, CA Windfarm


Book Description

The National Renewable Energy Laboratory (NREL) has requested that R. Lynette & Associates (RLA) complete a preliminary analysis of the costs and benefits of adding wind turbines to the existing diesel -based power system on San Nicolas Island, California (SNI). The SNI power system serves the Navy's Pacific Missile Test Center and Navy Range Instrumentation Test Site which are located on the island.This report documents the results of the study.













Island of the Blue Dolphins


Book Description

This is the first authoritative edition of one of the most significant childrenÕs books of the twentieth century. Winner of the 1961 Newbery Medal,ÊIsland of the Blue DolphinsÊtells the story of a girl left alone for eighteen years in the aftermath of violent encounters with Europeans on her home island off the coast of Southern California. This special edition includes two excised chapters, published here for the first time, as well as a critical introduction and essays that offer new background on the archaeological, legal, and colonial histories of Native peoples in California.ÊSara L. Schwebel explores the composition history and editorial decisions made by author Scott OÕDell that ensured the success ofÊIsland of the Blue DolphinsÊat a time when second-wave feminism, the civil rights movement, and multicultural education increasingly influenced which books were taught. This edition also considers how readers might approach the book today, when new archaeological evidence is emerging about the ÒLone Woman of San Nicolas Island,Ó on whom OÕDellÕs story is based, and Native peoples are engaged in the reclamation of indigenous histories and ongoing struggles for political sovereignty.




Computer-Model Results for the Beach-Escarpment-Induced Distortion of Onshore Wind Flow at the Northwest Point of San Nicolas Island, California


Book Description

A computer model developed by the Atmospheric Environment Service of Canada concluded that the beach escarpment underlying the Naval Research Laboratory's micrometeorological tower facility at San Nicolas Island, California, induced wind-speed amplifications ranging from 1.00 to 1.25 and wind-direction perturbations ranging from -5 deg to +5 deg, depending upon the altitude and wind direction, for measurements made from the NRL tower. The altitudes considered ranged from 5 to 35 m above the beach for onshore winds ranging over a 180 deg arc centered about the prevailing northwest wind direction. The model calculations were based upon a high-resolution aerial survey of the island beach escarpment. The model assumes that the tide height is at mean level, the horizontal length scale is 50 m, the roughness length of both the sea and island is 0.01 m, and the atmosphere is neutrally stable. The model results are presented in graphic form, to illustrate a typical example, and in tabular form as a function of altitude and wind direction, to facilitate the use of the results as a correction algorithm for future air-sea interaction experiments at the coastal facility.
