This web-page contains images and video related to our paper published in Science. The material presented here focuses on the deep ocean release experiment conducted at a depth of 3627 m in Monterey Bay. This experiment was the culmination of a series of trials conducted at increasing depths which were undertaken to test various ideas concerning the deep ocean sequestration of carbon dioxide in a real-world environment.

Our experiments were conducted using ships and remotely operated vehicles (ROVs) of the Monterey Bay Aquarium Research Institue (MBARI). For the shallow experiments at 349 m, 430 m and 905 m, we used the ROV Ventana deployed from the R/V Point Lobos. For the deep ocean release experiment at 3627 m, we used the ROV Tiburon deployed from the R/V Western Flyer.

    Adding liquid CO2 "dropwise" to the 4L beaker.
    Within an hour the liquid CO2 rose to the top of the beaker.
    The level of liquid CO2 also rose in the open cylinder.
