The Wisconsin roots of ground water hydrology.
We can trace the roots of ground water hydrology in the U.S. to Wisconsin at the end of the nineteenth century when there was a remarkable confluence of talent at the University of Wisconsin (now the University of WisconsinMadison), including T.C. Chamberlin, F.H. King and C.S. Slichter. Although none of these men likely would have identified himself as a hydrologist, each did seminal work in g...
متن کاملThe Boston University–five College Radio Astronomy Observatory Galactic Ring Survey
The Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey is a new survey of Galactic CO J = 1 → 0 emission. The survey used the SEQUOIA multi pixel array on the Five College Radio Astronomy Observatory 14 m telescope to cover a longitude range of l = 18– 55.7 and a latitude range of |b| < 1, a total of 75.4 square degrees. Using both position-switching and On-The-Fly ...
متن کاملLeiden Observatory
In this paper we summarize the main properties of the ENACS (the ESO Nearby Abell Cluster Survey), which was one of the ESO Keypro-grammes carried out in the first half of the 1990's, and we discuss some recent work on the properties of the galaxies in the rich clusters in the ENACS sample. We stress the importance of the ENACS sample as a local , volume-limited sample of rich ACO clusters, whi...
