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.

     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.

     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.
