Cyanobacteria: The cells that changed the world
Category: For Educators
Resource Type: PDF
Date Posted: 09/09/2011

In June 2001, the Ocean Explorer Thunder Bay ECHO Expedition was searching for shipwrecks
in the deep waters of the Thunder Bay National Marine Sanctuary and Underwater Preserve in
Lake Huron. But the explorers discovered more than shipwrecks: dozens of underwater sinkholes
in the limestone bedrock, some of which were several hundred meters across and 20 meters
deep.

Inside the deepest sinkholes, explorers found cyanobacteria growing in ways similar to those found in hydrothermal vents in the deepest parts of our oceans. In this lesson, students explore some aspects of cyanobacteria biology using data collected from the Thunder Bay Expedition.
