Oil Signals From the Deep: Analyzing CTD Data

The third lesson was designed to help students expand their understanding of ocean science and oil spill research. Students received hands-on experience working with CTD data from a NOAA research cruise. CTD refers to a package of electronic instruments that measure conductivity, temperature, and depth. Water samples can be collected at various depths using this equipment, and then it can be analyzed in a variety of ways. Students plotted the data in Excel and analyzed the plots to explain how levels of dissolved oxygen in the Gulf were affected by the oil spill. They discussed questions such as “how did dissolved oxygen vary with depth according to your graphs?” and “how were the graphs similar or different?”.

Think Like a Scientist Lesson Video

The second GOO lesson was all about how to think like a scientist. Students discussed some common misconceptions about what scientists look like, their habits and personalities, etc. Special guest speaker, Dr. Chris Reddy from the Woods Hole Oceanographic Institute (WHOI), gave students inside information about what being a scientist is all about. To wrap it up, students set up an experiment on the investigation of oil degradation over a 30 day time period. Different jars contained various combinations of oil, water, soil and fertilizers. Check out the video above to see what happened during our second GOO lesson.
