The first is the SPMR which is a tool used to measure how much light penetrates the water. The more light = the more heat. You can see in the photo that it is a small black device attached to a long cord. Toby and Olga lower the SPMR over the side and let it sink to 300 meters. Then they reel it back in just like a fishing pole. It tells them the "color" (wavelength) of the light at different depths. They do this over and over again in different locations in the ocean. Olga in the lab The next three pictures are of the CTD. This instrument is really big and needs a big machine called a winch to lift it in and out of the water. It has 12 tubes that fill up with water, each at a different depth. When the CTD is back on the ship, Toby and Olga fill labeled plastic bottles with the water. Then their work begins. First they run all the water samples through a filter to figure out how much phytoplankton was in the sample. Remember each tube on the CTD took in water at a different depth. So each bottle will tell a different story. They use this information to create a data graph which is used with other information to tell how the sun is heating the ocean.

The second picture is Olga in the lab working with the data.

Note for educators: Although Jennifer and Jane's reseearch cruise ended, the EPIC research continues. Please use this web site, Jennifer and Jane's lesson plans, daily logs, the videos, and the photos to educate your students about climate, El Niño, and scientific research in general.

Consider this web site, as well as the TAO web site, a resource for teaching your students.

Many organizations and countries are involved in funding the EPIC Experiment. Primary U. S. funding is provided by The National Science Foundation and The National Oceanic and Atmospheric Administration.
