Stonehenge an Observatory ?

In 1965, researchers found that the direction formed by two stones from Stonehenge, a mysterious ancient structure, pointed exactly to the direction of sunrise at solstice. Several similar coincidences were discovered, which lead many people to believe that Stonehenge was an ancient observatory. In this paper, we analyze this problem from a geometric viewpoint and show that similar coincidences...

The Long-Term Ecosystem Observatory: An Integrated Coastal Observatory

An integrated ocean observatory has been developed and operated in the coastal waters off the central coast of New Jersey, USA. One major goal for the Long-term Ecosystem Observatory (LEO) is to develop a real-time capability for rapid environmental assessment and physical/biological forecasting in coastal waters. To this end, observational data are collected from satellites, aircrafts, ships, ...

Components of an environmental observatory information system

Recently, an initiative within the hydrologic science and environmental engineering communities has emerged for the establishment of cooperative, large-scale environmental observatories. Scientists’ ability to access and use data collected within observatories to address broad research questions depends on the successful implementation of cyberinfrastructure. In this paper, we describe the arch...

Acts Broadband Aeronautical Experiment

In the last decade, the demand for reliable data, voice, and video satellite communication links between aircraft and ground to improve air traffic control, airline management, and to meet the growing demand for passenger communications has increased significantly. It is expected that in the near future, the spectrum required for aeronautical communication services will grow significantly beyon...
