摘要:
The National Space Science Data Center (NSSDC) of the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GSFC) provides access to data from and information about a plethora of scientific experiments from a variety of disciplines. To help fulfill this mission, NSSDC has developed a software package that supports a self‐describing data structure. This structure, called the Common Data Format (CDF), provides true data independence for applications software that has been developed at NSSDC. Scientific software systems at NSSDC use this construct so that they do not need specific knowledge of the data with which they are working. This permits users of such systems to apply the same functions to different sets of data. This data‐independent concept was first introduced at NASA in support of atmospheric and climatic research via the Pilot Climate Data System (PCDS), a scientific information system and analysis system developed at NSSDC [Treinish, 1984;Reph et al., 1986]. The users of such data‐independent NSSDC systems as the PCDS rely on their own knowledge of different sets of data to interpret the results, a critical feature for the multidisciplinary studies inherent in the earth and space sciences. Such CDF‐based software can use the information available through the CDF software package to inform a user about contents, history, and structure of the data that are supported in a gi

摘要:
Scientists will probe the Greenland ice cap this month in an attempt to prove that an undiscovered fifth force exists in the universe. The scientists will measure the Newtonian gravitational constant and attempt to prove that it is dependent on distance. Their findings could have a significant impact on modern physics, including the forcing of a recalculation of the masses of planets and stars.

摘要:
An AGU Chapman Conference on Fast Glacier Flow was held at Whistler Village, Canada, from May 4 to 8, 1986. The timing of the conference seemed particularly propitious because of results of recent observational programs, such as the breakup of the tidewater Columbia Glacier in Alaska, the imbalance of Ice Stream B in Antarctica and the existence of deforming sediment under it, and the surge of Variegated Glacier in Alaska.

摘要:
Leslie Smith is an outstanding young scientist who, in a very short span of time, has blossomed into one of the most creative and innovative researchers in the field of hydrogeology. His work, which these days extends beyond groundwater and into other branches of geophysics, is consistently at the cutting edge of the science and has been instrumental in shaping our modern views about the way water, mass, and heat move in groundwater systems.
