Title Attracting and Controlling Coastal Pelagic Fish with Nightlights Type Journal Article
Year (up) 1973 Publication Transactions of the American Fisheries Society Abbreviated Journal Transactions of the American Fisheries Society
Volume 102 Issue 4 Pages 816-825
Keywords Animals
Abstract Field experiments were conducted in the northeastern Gulf of Mexico to evaluate techniques for using sequentially‐operated lamp strings and moving lamps to lead and concentrate light‐attracted coastal pelagic fishes. Fish were successfully led between sequentially‐operated under‐water lamps separated by distances up to 20 meters. Mobile lamps were used to lead fish distances up to approximately 1 kilometer. Fish aggregations which form daily around man‐made structures were held after dark and led clear with moving lamps for capture by purse seine. A combination of nightlighting and man‐made structure fish attraction techniques are proposed for harvesting coastal pelagic fish aggregations which occur around existing petroleton drilling platforms, well heads, and other areas presently inaccessible to conventional fishing gear.

Title Burning Waste Gas in Oil Fields Type Journal Article
Year (up) 1973 Publication Nature Abbreviated Journal Nature
Volume 245 Issue 5425 Pages 375-376
Keywords Remote Sensing
Abstract I WAS recently amazed by some night-time spacecraft photographs, exemplified by Fig. 1, that present graphic evidence of waste and pollution. These were obtained by the United States Air Force DAPP system which has sensors in the visible 0.4 to 1.1 µm band and an infrared imaging system in the 8 to 13 µm band (ref. 1 and J. L. McLucas, personal communication). The visible band sensor is Capable of responding to very dim light with a controllable threshold (T. O. Haig, personal communication) and it provided these pictures. The lights of cities are clearly visible, as are the aurora, surface features illuminated by moonlight, and fires such as those caused by burning gas from oil fields and refineries. Much power is evidently being generated to light the cities of the world since at the inhabited areas are clearly outlined. It is also apparent that, in the process of extracting liquid petroleum from beneath the surface of the Earth, abundant gas supply has been discovered but is not used. Being unable to contain the gas or to transport it to a user, it is simply burnt.

Title A simple propagation law for artificial night-sky illumination Type Journal Article
Year (up) 1973 Publication The Observatory Abbreviated Journal
Volume 93 Issue Pages 117-120
Keywords Skyglow
Abstract The problem of locating new large astronomical observatories in sites which have a suitably dark night sky (artificial excess of the order of omi) is becoming increasingly difficult in Europe and the United States, on account of extensive urban development, the high luminous efficiency of modern discharge lighting, and the scattering of light in an atmosphere contaminated by aerosols. To investigate the artificial illumination of the sky over large regions on the basis of necessarily limited observations, one needs an expression for the zenith brightness produced by towns of known site and distance.

The exact derivation of such a law is exceedingly complex, involving the computation of the radiation transfer in an atmosphere with absorption, multiple scattering, and complicated physical and geometrical parameters. Notwithstanding these difficulties, it is possible to obtain a useful physical insight into the general form of this law by considering a very simplified model, consisting of a homogeneous atmosphere, in which vertical heights are small in relation to the horizontal distances between town and observatory, and which the scattering is limited to a cone of small angle whose axis lies in the direction of the incident beam. The limited scale height and optical thickness of the real atmosphere, and the forward-scattering characteristics of aerosols lend some plausibility to these simplifications.

Title Defense Meteorological Satellite Program (DMSP) – User's Guide Type Report
Year (up) 1974 Publication Abbreviated Journal
Volume ADA007678 Issue Pages
Keywords Remote Sensing
Abstract The capabilities of the spacecraft, sensors, and data processor for the Defense Meteorological Satellite Program are described. Many meteorological and geophysical uses of these data are examined, and examples used to illustrate the capabilities of the system to tailor the imagery for a large variety of present and future users.

Title Meteorological Satellite Coverage of Florida Everglades Fires Type Journal Article
Year (up) 1976 Publication Monthly Weather Review Abbreviated Journal Mon. Wea. Rev.
Volume 104 Issue 10 Pages 1330-1332
Keywords Remote Sensing
Abstract Several bog fires in the Florida. Everglades in the spring of 1974 created a great deal of acrid smoke which was advected northward and reduced visibilities at many locations, including Patrick AFB. A subsidence inversion and low-level southwesterly flow combined on 1 May to send a plume of smoke into central Florida which reduced visibilities to 2 mi or less in areas south of Cape Canaveral. The 1430 GMT NOAA 3 satellite photo revealed the existence of the plume to the Cape Canaveral Forecast Facility (CCFF) forecasters. Later, satellite imagery taken between 1340 and 2110 GMT was received which showed movement of the plume offshore. These photographs gave evidence that timely use of meteorological satellite data can greatly aid in the forecasting of reduced visibilities due to smoke. In addition, high-resolution infrared and visual imagery from Defense Meteorological Satellite Program and NOAA satellites gave strong evidence that these data can be used to pinpoint and monitor brush and forest fires as well as provide local meteorological data vital to the fire fighting effort.
