Water Resources Data - New Jersey, Water Year 1999, Volume 3, Water-Quality Data
Water-resources data for the 1999 water year for New Jersey are presented in three volumes, and consists of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground water. Volume 3 contains a summary of surface and ground water hydrologic conditions for the 1999 water year, a listing of current water-resource projects in New Jersey, a bibliography of water-related reports, articles, and fact sheets for New Jersey completed by the Geological Survey in recent years, water-quality records of chemical analyses from 133 surface-water stations, 46 miscellaneous surface-water sites, 30 ground-water stations, 41 miscellaneous ground-water sites, and records of daily statistics of temperature and other physical measurements from 17 continuous-monitoring stations. Locations of water-quality stations are shown in figures 11 and 17-20. Locations of miscellaneous water-quality sites are shown in figures 29-32 and 34. These data represent the part of the National Water Data System operated by the U.S. Geological Survey and cooperating Federal, State, and local agencies in New Jersey.

The display flight of The North American Ruddy Duck
Sexual behavior of the North American Ruddy Duck ( Oxyura jamaicensis ), as summarized by Johnsgard (1965: 323-327), includes a display variously referred to as the ringing rush (Johnsgard 1965: 325; 1967), ring rush (Johnsgard 1966), and/or display flight (Johnsgard 1966, 1967), which males perform as a short rush across the water surface, generally toward females. Differences of opinion exist concerning the description of the sound emitted during the display and the exact mechanics of sound production. Bailey (1919) described "a noise suggesting castanets" accompanying what probably was the display flight. Johnsgard described the noise as ringing (1965: 325) and rattling (1967). Buzzing has been used to characterize the sound produced during the display flight of the Australian Blue-billed Duck ( O. australis ), a display "which appears to correspond exactly" to the ring rush of O. jamaicensis (Johnsgard 1966). We prefer to describe the sound as popping. Wetmore (1920: 247), without naming the display, described "a great boiling in the water with wings and feet." Johnsgard attributed the noise to the wings alone (1965: 325) and, later "wings and/or feet striking the water" (1967), while Palmer (1975: 513) assigned the sound to the feet.
