Carried aboard the SeaStar spacecraft, the new orbiting satellite instrument SeaWiFS (the Sea-viewing Wide Field-of-view Sensor Project), views every square kilometer of cloud-free ocean every 48 hours. With each pass, it charts ocean color, which enables it to quantify the concentration of microscopic marine plants called phytoplankton. The color in most of the world's oceans varies with the concentration of chlorophyll and other plant pigments in the water--the more phytoplankton present, the greater the concentration of plant pigments and the greener the water. By charting water color against the Coastal Zone Color Scanner (CZCS), shown in the key with the image, SeaWiFS can derive chlorophyll concentrations and from them determine phytoplankton concentrations. The oceanographic community uses these data about the abundance of phytoplankton and other primary producers--that is, the algae and bacteria at the bottom of the food chain that use sunlight and chemicals, rather than other organic material, as sources of energy--to study ocean processes on a global scale. The information can also be used to assess the ocean's role in the global carbon cycle and the exchange of other critical elements and gases between the atmosphere and the ocean. The SeaWiFS mission is part of the National Aeronautics and Space Administration's "Mission to Planet Earth" project, whose goal is to help scientists and researchers gain understanding of the Earth as a functioning system by viewing it from space.

The National Science Foundation (NSF) provides awards for research and education in the sciences and engineering. The awardee is wholly responsible for the conduct of such research and preparation of the results for publication. The Foundation, therefore, does not assume responsibility for the research findings or their interpretation.

The Foundation welcomes proposals from all qualified scientists and engineers and strongly encourages women, minorities, and persons with disabilities to compete fully in any of the research- and education-related programs described here. In accordance with federal statutes, regulations, and NSF policies, no person on grounds of race, color, age, sex, national origin, or disability shall be excluded from participation in, be denied the benefits of, or be subject to discrimination under any program or activity receiving financial assistance from the National Science Foundation.

Facilitation Awards for Scientists and Engineers with Disabilities (FASED) provide funding for special assistance or equipment to enable persons with disabilities (investigators and other staff, including student research assistants) to work on NSF projects. See the program announcement or contact the program coordinator at (703) 306-1636.

The National Science Foundation has TDD (Telephonic Device for the Deaf) capability, which enables individuals with hearing impairment to communicate with the Foundation about NSF programs, employment, or general information. To access NSF TDD, dial (703) 306-0090; for FIRS, 1-800-8339.


The Antarctic Journal is a medium for information about, and related to, the U.S. Antarctic Program. NSF welcomes ideas for improvement. Send comments to Winifred Reuning at WReuning@nsf.gov (e-mail) or Editor, Antarctic Journal, Office of Polar Programs, National Science Foundation, 4201 Wilson Boulevard, Arlington, Virginia 22230 (703-306-1033).

The Antarctic Journal invites contributions from members of the antarctic science, logistics, and policy communities who want to communicate their work and ideas to an audience of specialists and scientifically literate nonspecialists. The Antarctic Journal is not peer reviewed. It provides reports on U.S. activities in Antarctica and related activities elsewhere and on trends in the U.S. Antarctic Program. The September 1997 online issue contains author guidelines for submitting manuscripts to the review issue, as well as information about submitting materials for the monthly online issues.
