摘要:

As a concerned scientist, I think that having a global nuclear waste repository is a reachable goal for human beings. Maybe through this common goal, mankind can begin to treat each other as brothers and sisters. So far, most human activities are framed by national boundaries, which are purely arbitrary. Breaking through these national boundaries will be very beneficial to human beings.Formation of the International Geosphere‐Biosphere Program in 1986 indicates a growing awareness on the part of scientists regarding Earth as a system. The Apollo missions gave us a chance to look back at Earth from space. That perspective emphasized that our Earth is just one system: our only home. It is in deed a lonely boat in the high sea of dark space. We must take good care of our “bo

摘要:

The technology of flow cytometry and cell sorting has existed for ∼20 years, and its potential applications to oceanography have been obvious to many for nearly as long. Its introduction into oceanography did not occur, however, until the early 1980s [Yentsch et al.1983;Olson et al. 1983]. The introduction was made possible largely t hrough the funding of instruments dedicated to oceanographic applications by the U.S. National Science Foundation, the Office of Naval Research, and private institutions. In the last 5 years, interest in this new tool has grown significantly, and the number of flow cytometry facilities dedicated to applications in oceanography and limnology in the United States, Canada, and Europe has expanded to a surprising degree (Table 1

摘要:

The Solar Physics Branch of the newly formed Space Physics Division in the Office of Space Science and Applications of the National Aeronautics and Space Administration (NASA) Headquarters has an ongoing program of Supporting Research and Technology (SR&T) to encourage basic research in solar physics relevant to NASA's flight programs. Grants and contracts are issued to universities, industry, nonprofit institutions, NASA centers, and other government agencies for this purpose. We emphasize that the rationale for funding meritorious, unsolicited research proposals received by NASA is to provide support for its flight missions. The objectives of these space missions are the study of solar phenomena in a comprehensive manner across a variety of solar regimes, starting at the Sun's core, where energy is generated, and extending out through the solar corona , where the solar wind is formed.

摘要:

Plans for continental scientific drilling, supported by the National Science Foundation (NSF) through the DOSECC consortium of universities have been given a new direction as a result of the failure of the NSF budget to reach expected levels. Very deep drilling will not be initiated for some time because of its high cost, but an active program of drilling to depths of 1–5 km is being developed in its place. For the next several years, DOSECC (Deep Observation and Sampling o f the Earth's Continental Crust, Inc.) will focus on proposals for drilling experiments to improve our understanding of dynamic processes in the shallow crust. As a result of this change in emphasis, there is now an opportunity to propose experiments of this kind and to have them accepted for drilling over the course of the next few year

摘要:

Polynyas are areas of open water that occur at specific, recurrent locations in the polar regions and that are surrounded by ice‐covered waters. They have been of interest historically because they are centers of upper trophic level biological activity and were consequently foci of both commercial whaling activities and of native subsistence hunting. They have more recently become of interest from a basic research viewpoint because they are typified by intensive biological activity and energetic physical processes. They are similar, in many respects, to the marginal ice zones, which are an ongoing focus of considerable oceanographic research. Polynyas can be conceptually envisaged as polar oceanic “oases” in which biological activities are focused locally while they are surrounded by relatively unproductive waters. Polynyas serve as outposts of enhanced production within the pack ice remote from the biologically rich marginal ice
