Purpose:
To transfer data from an EXCEL spreadsheet, (or equivalent program in other software) presented on the racerocks.com website to your own computer in order to be able to graph trends and analyze relationships.
Procedure :1. Open a blank workbook in EXCEL on your computer. Next open one of the files saved from EXCEL below and then with your cursor highlight the columns that you want to transfer to your open EXCEL workbook, and press COPY. ( If your computer is low on memory, you may have to close the web page before opening the EXCEL application.)

2. Copy and Paste the data from the web page directly into your blank EXCEL workbook.

3. You now have our original data on your machine and you can proceed to do any one of the many manipulations possible in the EXCEL program. You can also copy and paste in other month’s data in order to get a larger data set .

4. If you come up with a way of analyzing the data which is particularly creative, we would be interested in attaching it on racerocks.com. Just e-mail it as an attachment . e-mail: Garry Fletcher

5. You are welcome to use this data for educational purposes, you are just asked to reference the source as:

LAB: Using Temperature and Salinity Data for an Excel exercise

Posted on by
Purpose:
To transfer Environmental Data being recorded at Race Rocks from a spread sheet presented on the internet to your own computer in order to be able to graph trends and analyze relationships.
Background:
Long term data bases are very important for a number of reasons. You may wish to write down in your assignment notes some of the applications you could use for such data. Certainly patterns of cyclic activity and even events such as Climate Change can be detected from the Race Rocks Data. Try to come up with a few other applications. We intend to make a complete range of environmental data from data sensors as these get installed.See this file for the Data Recording IndexSee also IDEAS FOR STATISTCS ASSIGNMENTS
USING EXCEL DATA FROM racerocks.com 

RACE ROCKS TEMPERATURE AND SALINITY EXERCISE
Since 1921 the Light keepers at Race Rocks have recorded some basic climatic data at Race Rocks. They started by taking daily sea water temperatures and in 1936 added daily salinity measurements to their measurements. The record is fairly complete except for a few years during the second world war, and so far we have not been able to determine why those records were not kept at that time. 1.This is a file with the daily sea temperatures and salinity and atmospheric data since the year 2000, as recorded by Mike Slater:2. We were able to get this complete monthly mean data base for Temperature….1921->present and this complete monthly mean data base…1936-present for Salinity from the Institute of Ocean Sciences.

3. Copy and Paste the data for the years you want to analyse from the web page directly into your blank EXCEL workbook.

4. You now have our original data on your computer and you can proceed to do any one of the many manipulations possible in the EXCEL program. You can also copy and paste in other month’s data in order to get a larger data set .

5. Take the opportunity to creative in the way you look at and interpret data, we would be interested in attaching your findings to this website. Send comments to: Garry Fletcher Just e-mail your analysis as an attachment.

Tidepool # 6 “Anita’s Pool”

On the West side of Great Race Rocks is a tidepool that we have been observing for many years. Dr. Anita Brinckmann-Voss has done research on the seasonality of hydroids in this pool and it is published as:

Dr. Anita Brinckmann-Voss doing research on seasonality of Hydroids in Tidepool #6

Abstract:

An assemblage of 27 hydroid species was reported from a tide pool in the lower rocky intertidal zone, and compared with 42 hydroids of the adjacent subtidal region. Location of hydroids within the pool, seasonal occurence, growth and sexual maturity were tabulated, and some systematic aspects discussed. Possible causes of hydroid species diversity were considered, including location of the tide pool in an area of tidal rapids, and shading by surfgrass and rock cliffs during low tide

The unique feature about this pool is that it is deep enough – ( 1 meter) and it gets swells that refresh it even when the tide level is low. Garry is standing on the lip of the pool as the water from a swell spills out and cascades down to the lower level of the ocean.

ABSTRACT: The interaction of a stratified flow with an isolated topographic feature can introduce numerous distur- bances into the flow, including turbulent wakes, internal waves, and eddies. Measurements made near a “bump” east of Race Rocks, Vancouver Island, reveal a wide range of phenomena associated with the variable flow speeds and directions introduced by the local tides. Upstream and downstream flows were observed by placing two acoustic Doppler current profilers (ADCPs) on one flank of the bump. Simulta- neous shipboard ADCP surveys corroborated some of the more striking features. Froude number conditions varied from subcritical to supercritical as the tidal velocities varied from 0.2 to 1.5 m s1. During the strong ebb, when the moored ADCPs were located on the lee side, a persistent full-water-depth lee wave was detected in one of the moored ADCPs and the shipboard ADCP. However, the placement of the moorings would suggest that, by the time it appears in the moored ADCP beams, the lee wave has been swept downstream or has separated from the bump. Raw ADCP beam velocities suggest enhanced turbulence during various phases of the tide. Many of the three-dimensional flow characteristics are in good agreement with laboratory studies, and some characteristics, such as shear in the bottom boundary layer, are not.

Installation of Succession plates for the Tidal Energy project

Posted on by

This video shows the installation process for the tidal energy generator research project. This was carried out by Chris Blondeau and the Pearson College Divers in order to determine which surfaces discouraged growth in the waters at Race Rocks. As a result, Titanium was used in the construction of some parts of the generator as it was one of the metals most resistant to fouling.
