<h1>Buoy Analysis</h1>
<h2>NOAA data for stations off the California coast from 1982 to 2015</h2>
<hr>
<h3>Project Goal</h3>
<blockquote>
Create visualization of California coastal ocean temperature data to find monthly and yearly trends.
<br><br>
Visualization should invite interaction to create and answer questions such as:
<ul>
<li>Are ocean temperatures increasing?</li>
<li>What are the visible effects of El Nino?</li>
<li>What is the temperature of the ocean near San Francisco?</li>
</ul>
</blockquote>
<p>
Data source: <a href="http://www.ndbc.noaa.gov/">National Data Buoy Center</a>. Historical data, such as <a href="http://www.ndbc.noaa.gov/station_history.php?station=46213">46213 Cape Mendocino</a>, is mostly available since 1982. Extract, transform, and reduce scripts run on Node, publically available in <a href="http://gogs.benburlingham.com/ben.burlingham/buoy-analysis">source code</a>.
</p>
<p>
This visualization is created using D3 and Three.js libraries.
