Global Phytoplankton Distribution Story Map
This story map is intended to be used with students who have access to a computing device in a 1:1 or 1:2 setting. Using various visualizations (i.e., images, charts, and graphs), students will explore global phytoplankton distribution using chlorophyll concentration data. Students will investigate the processes that allow phytoplankton populations to thrive, as well as how their role in the carbon cycle impacts the other spheres of the Earth System.
Virtual Teachers: Make a copy of the Google Form of your choice so that you may assign it directly from your Google Drive into your Learning Management System (e.g., Google Classroom, Canvas, Schoology, etc.). Do you need help incorporating these Google Forms into your Learning Management System? If so, read this Guide to Using Google Forms with My NASA Data.
- Students will analyze and compare multiple variables of the Earth System as they analyze the global distribution of phytoplankton.
- Students will observe annual patterns in chlorophyll concentration and shortwave radiation.
- Students will construct explanations and conclusions using evidence.
- What conditions within the Earth System allow phytoplankton to thrive?
- How do changes in shortwave radiation affect the distribution of phytoplankton?
- What affect do sea surface temperature and ocean currents have on distribution of phytoplankton?
- How does chlorophyll concentration indicate the presence of phytoplankton?
- How do phytoplankton contribute to the carbon cycle?

Teacher Background Information
At the bottom of the ocean's food chain, phytoplankton account for roughly half of the net photosynthesis on Earth. Their photosynthesis consumes carbon dioxide and plays a key role in transferring carbon from the atmosphere to the ocean. Unlike the plant ecosystems on land, the amount of phytoplankton in the ocean is always followed closely by the abundance of organisms that eat phytoplankton, creating a perpetual dance between predators and prey.

Why Does NASA Study This Phenomenon?
Phytoplankton account for roughly half of the net photosynthesis on Earth. Their photosynthesis consumes carbon dioxide and plays a key role in transferring carbon from the atmosphere to the ocean. Unlike the plant ecosystems on land, the amount of phytoplankton in the ocean is always followed closely by the abundance of other organisms that eat phytoplankton. By analyzing the NASA ocean color satellite data, scientists have provided new insights into how climate and ecosystem processes effect and are affected by the growth cycles of phytoplankton.
STEM Career Connections
Botanist or Plant Scientist – Research plant characteristics like their physiological processes, evolutionary history, resistance to disease, and relationships to other parts of the Biosphere and Earth System
Remote Sensing Specialist – Use sensors to analyze data and solve regional or global concerns such as natural resource management, urban planning, and climate and weather predictions
Environmental Engineering – Use their understanding of engineering and sciences such as soil science, biology, and chemistry, to develop solutions to problems in the environment which could include recycling, waste disposal, public health, or water and air pollution control
