Title DMSP calibration Type Journal Article
Year (up) 1979 Publication Journal of Geophysical Research: Space Physics Abbreviated Journal J. Geophys. Res.
Volume 84 Issue A8 Pages 4134-4144
Keywords Remote Sensing
Abstract Although DMSP satellite data are widely used, there has been no reliable absolute calibration. Coordinated data with ground‐based photometers allow a calibration curve of film density versus 4728 N2+ intensity to be derived. The DMSP satellites (5C series) record airglow and can detect auroral forms of intensities ≥50 R of 4278 N2+. It is estimated that the 5D series satellites are capable of detecting auroras with ∼25 R of 4278 N2+.

Title Effects of moonlight on the vertical migration patterns of demersal zooplankton Type Journal Article
Year (up) 1980 Publication Journal of Experimental Marine Biology and Ecology Abbreviated Journal Journal of Experimental Marine Biology and Ecology
Volume 44 Issue 2 Pages 133-156
Keywords Animals
Abstract The diel vertical migration patterns of demersal zooplankton, those organisms which habit bottom substrates but periodically emerge to swim freely in the water column, water determined throughout the lunar cycle. Demersal zooplankton were quantitatively sampled on a subtidal sand flat in the Gulf of California every 2 h for 24-h periods at new, full, first, and last-quarter moons, both as they emerged into the water column and as they returned to the benthos. Demersal zooplankton rarely migrated during daylight. Three general patterns of migration were observed. (1) Polychaetes and cumaceans emerged from the benthos at dusk, regardless of the phase of the moon. Polychaetes returned to the benthos throughout the night while cumaceans returned near dawn. (2) Species of amphipods and isopods exhibited significant avoidance of moonlight, delaying emergence until moonset or returning to the benthos at moonrise. (3) Species of copepods, mysids, shrimp, Branchiostoma (cephalochordate), and tanaids emerged into the water column throughout the night. The timing of migration was highly variable and did not correlate with the presence or absence of moonlight. Large zooplankton migrated less frequently into the water column during moonlit periods than small forms, suggesting that nocturnal predation by visually oriented planktivorous fish may be an important selective pressure.

Demersal zooplankton emerged into artificially darkened emergence traps in significantly higher numbers during daylight and during full and quarter moons than into undarkened control traps, demonstrating that absence of light is a major cue stimulating migration. Reentry traps resting on the bottom captured higher densities of demersal zooplankton than either emergence traps or reentry traps suspended off the bottom. Thus, many demersal zooplankton remain near the bottom, rarely swimming far into the water column. Some trap avoidance was observed and current methods for collecting demersal zooplankton are evaluated. Since most demersal zooplankton remained in the water column only a short time, dispersal, particularly over short distances, may be a major advantage of migratory behavior. Migration facilitates rapid recolonization of disturbed or defaunated sites, disrupts and mixes bottom sediments, and results in daily variation in the microdistribution, patchiness, and species composition of the benthic fauna.

Title Light suppresses melatonin secretion in humans Type Journal Article
Year (up) 1980 Publication Science Abbreviated Journal Science
Volume 210 Issue 4475 Pages 1267-1269
Keywords Human Health
Abstract Bright artificial light suppressed nocturnal secretion of melatonin in six normal human subjects. Room light of less intensity, which is sufficient to suppress melatonin secretion in other mammals, failed to do so in humans. In contrast to the results of previous experiments in which ordinary room light was used, these findings establish that the human response to light is qualitatively similar to that of other mammals.
