isograv (countable かつ uncountable, 複数形 isogravs)

1. An isoline on a map joining points of equal gravitational potential.
   • 1954, Astounding Science-fiction, volume 52, number 4-53, page 99:

     They've plotted what they call isogravs, lines of equal-g, and riding parallel to them seems to do funny things.

   • 1988, Frank Pohlemann, “A concept for a future autonomous European space station”, in Acta Astronautica, volume 18:

     The favorable microgravity conditions 389 resulting from this are charted in figure 7, which shows the isograv envelopes of constant gravity gradient acceleration experienced aboard the station.

   • 1990, Charles R. Baugher, Measurement and Characterization of the Acceleration Environment on Board the Space Station, page 24-5:

     Figure 5 shows the isogravs on a solar inertial station. You get constant gravity just like you do on the LVLH station as you come out of the orbit plane.

   • 2001, John Dalmas, Soldiers:

     Already isogravs showed the system's primary, an F9 star without a name of its own, unless you consider catalog numbers.

2. (physics) Abbreviation of isogravity.
   • 1997 March, M.N. Melsom, J. Kramer-Johansen, T. Flatebø, C. Müller, G. Nicolaysen, “Distribution of pulmonary ventilation and perfusion measured simultaneously in awake goats”, in Acta Physiologica Scandinavica, volume 159, number 3:

     Based on values obtained by Eqns (1a) and (1c), we computed for VI, QI and VI\QI-ratio one coefficient of variation (CV) accounting for total heterogeneity (CV total) and one accounting for variation within isogravitational planes (CV isograv).

3. (physics) Abbreviation of isostatic residual (gravity) anomaly.
   • 2014 February 19, Jeffrey S. Evans, Joseph M. Kiesecker, “Shale gas, wind and water: Assessing the potential cumulative impacts of energy development on ecosystem services within the Marcellus play”, in PLoS One:

     The magnetic anomaly rasters (bouguerbougure, isograv かつ magnetic) were obtained from the USGS as was the thermal maturity point data.

   • 2017 March, Lara M Juliusson, Kevin E Doherty, “Oil and gas development exposure and conservation scenarios for Greater sage-grouse”, in Applied Geography, volume 80:

     Isostatic residual anomaly, isograv: Isostatic residual anomaly data removes the long-wavelength part of the gravity field to correct for topographic load and provide for surface gravity mapping.
