Data Activity 4C
Comparing Regional Chlorophyll Patterns Around the World Application Data Activity

Your Objective

Explore chlorophyll-a concentration data, from the 3-wavelength fluorometer, over time at different locations to investigate regional differences and similarities in primary productivity.

Coastal Endurance and Coastal Pioneer are two of the seven OOI arrays throughout the Pacific and Atlantic Oceans.
Schematic of the instruments and moorings at the Coastal Endurance Washington Offshore station in the Pacific Ocean. Data in this activity were collected from the Shelf Surface Mooring (D).

Challenge C

How does primary productivity vary around the world?

Exploration

Investigate the "Chlorophyll-a Concentration" data in the Fall among six stations: Northern Polar Pacific Ocean (Global Station Papa Array); Temperate Pacific Ocean (Coastal Endurance Array); Southern Polar Pacific Ocean (Global Southern Ocean Array); Northern Polar Atlantic Ocean (Global Irminger Sea Array); Temperate Atlantic Ocean (Coastal Pioneer Array); Southern Polar Atlantic Ocean (Global Argentine Basin Array).
