Your Objective

Look for patterns in the "Chlorophyll-a Concentration" data at each of the stations near the Polar Zones of the Pacific Ocean (Station Papa Array; Southern Ocean Array) and Atlantic Ocean (Irminger Sea Array).

Data Tip: Select each location to explore the data from near the Polar Zones of the Ocean. Zoom in and out of the data to look at different time scales to investigate patterns across time. Note that when you select a specific station, it will zoom into the late Summer to early Fall season appropriate for the hemisphere the station is in.

Interpretation and Analysis Questions

  1. How did the chlorophyll-a concentration vary over time near the Polar Zones of the Ocean?
  2. What is your evidence for the pattern, which you observed, in the data over time near the Polar Zones of the Ocean?
  3. What questions do you still have about patterns in chlorophyll-a concentration over time near the Polar Zones of the Ocean?
