Abstract: An image bearing surface. In accordance with a first embodiment of the present invention, an image bearing surface comprises a surface for interacting with a writing element of an electronic interactive device to embody a user created image thereon. The image bearing surface includes a first demarked region for accepting a plurality of user created images, each of the images representing a user response to a question, and a second demarked region for accepting a plurality of user created images identifying characteristics of the first demarked region to the electronic interactive device. The first and second demarked regions comprise a permanently printed encoded pattern of location information on the surface for providing location information to the electronic interactive device. The image bearing surface may be used to facilitate the use of supplementary educational testing materials.

Abstract: The present invention provides a method for removing CO.sub.2 from the atmosphere. The method comprises the step of delivering a source of nitrogen to the mixed layer of the ocean to cause an increase in the number of phytoplankton in the mixed layer and thereby increase the amount of photosynthesis carried out by the phytoplankton. The source of nitrogen is delivered to the mixed layer at a location where an ocean current will carry the source of nitrogen and phytoplankton over a region of the ocean having a depth sufficient to allow dead phytoplankton and organic material derived from the phytoplankton to fall from the mixed layer and enable carbon originating from the CO.sub.2 to be sequestered from the atmosphere.
