Your Objective

Look for patterns in the "Chlorophyll-a Concentration" data at each of the stations in the Temperate Zones of the Pacific Ocean (Coastal Endurance Array) and Atlantic Ocean (Coastal Pioneer Array; Argentine Basin Array).

Data Tip: Select each location to explore the data from around the Temperate Zones of the Ocean. Zoom in and out of the data to look at different time scales to investigate patterns across time.
