Part 4—Analyze Graphs to Predict the Bloom

Step 1 –
Group the Graphs by Buoy Location

Examine the changes in water temperature, density, and salinity at each of the four buoy locations.

Samples of the 2004 graphs can be used as examples and are linked here. Water Temperature, Density, and Salinity Graphs

Step 2 –
Analyze the Graphs to Predict the Timing of the Spring Bloom

Interpret your graphs for each location to understand what was happening to the water column throughout the year and when a bloom might occur. Use the following questions to guide you in making a prediction about the timing and location of the spring bloom for 2009. Refer back to Part 1, or consult other resources as necessary.
