Part 2—Investigate Sea Surface Temperature (SST) in the Pacific Ocean
Step 1 –
Set up a Base Map
- Start My World GIS by double-clicking its program icon or by going to the Start Menu (PC) and navigating to the application.
- From the Welcome screen, click the link titled "Get Started" at the bottom of the screen.
- Switch to the World data library. Then drag the Lines of Latitude & Longitude and the Continents layers to the layer list.
- Click the Visualize tab below the menu items to switch from Construct Mode to Visualize mode. To find the modes, look at the tabs along the top of the map. Their names will show as your cursor hovers over them.
- Once in Visualize, click the Zoom to All button to re-size the map to fill the window.
Step 2 –
Import Sea Surface Temperature (SST) data from the Pacific Marine Environmental Laboratory (PMEL)
- Import SST data for all weekly data for the month of December from 1982 to 1998. You'll import this layer from the Internet using My World and the THREDDS catalog at http://ferret.pmel.noaa.gov/thredds/dodsC/data/PMEL/catalog.xml
Be patient while your computer retrieves the list of data available from this server. It can take a minute or so to appear.
The PMEL server offers a range of Earth system data. Whenever you click the name of a data file (files are inside the folders), a brief description of the data appear on the right.
- Use the THREDDS Catalog Chooser to import the "reynolds_sst_wk" for every week in December from 1982 to 1998.
