An Introduction to Real Time Data

Questions: Where is the ocean warming? How is the ocean becoming more acidic? How are “dead zones” forming? Why are species going extinct? How can we respond to environmental disasters?

The Answer: Research Learn as much as we can about the ocean so we can answer those questions!

How do dead zones form? click here to find out.

Question #1 How do dead zones form? (answer on paper, word file to be ed, or set this up in moodle)

Scientific instruments like Bouys, Gliders, Drifters, and ROV’s are used to collect data that detects, predicts, and documents dead zones.

Define the following and list what types of data are typically collected with each device: Buoys: Gliders: Drifters: ROVs: Again, write on paper, , or moodle

Check the data: Buoys Go to (National Data Bouy Center) NOAA site: Click HereClick Here Use the google map browser to find the STONEWALL BANKS bouy 20 nautical miles off the coast of Newport, Or. Click on it. Click on View History. Scroll down to climatic summary and click on wind speed. In what month do you find the highest average winds? Between 1991 and 2008, in what month do you find the lowest average winds?

Check the data: Gliders Go to CMOP site: Click HereClick Here Choose a mission. Create a graph showing time on x-axis, depth on y-axis, and temperature in the color field. What relationship do temperature and depth have? Now change the color field to density. What relationship do density and depth have? Why do you think scientists deploying so many drifters lately?

Check the data: Drifters Go to the global drifter program site: Click here!Click here! Click on the link: view in google maps Zoom out to see all the drifters currently deployed in the ocean. Click on one near the equator. Click the link for trajectory shaded by SST (sea surface temperature) give a rough estimate for a min-max range of temperatures. Click on one near the north or south pole. Click the link for trajectory shaded by SST. Give a rough estimate for a min-max range of temperatures. Why do you think there are so many drifters placed around the earth?

Check the data: ROVs Watch the following video: Click Here!Click Here! How can ROV’s (remotely operated vehicles) be used to collect data? How would an ROV be used to monitor animal populations in an area over time? Now watch some videos from this site: Click Here! Click Here! What is different about this video?
