agency_code |
A numeric code identifying the contributing source of a dataset. |

|
Bouguer_anom_267 |
A Bouguer anomaly calculated using a Bouguer slab density of 2.67g/cc.Note that the
gravity anomaly calculations were computed using the GRS67 model. |
| 1 |
|
Bouguer_anom_sd |
The standard deviation associated with the Bouguer Anomaly. |

edit_code |
A National Geodetic Survey code used to summarize record editing actions. |

|
latitude |
This is the geographic latitude expressed as a decimal number. The units are degrees.
The range is -90.0 to +90.0. |
| 1 |
|
longitude |
This is the geographic longitude expressed as a decimal number. The units are degrees.
The range is -180.0 to +180.0, where plus designates East longitude and minus designates
West longitude. |
| 1 |
|
sea_level_elev_m |
Height of the surface of observation above sea level, in meters (NOTE: most often
from terrain surface but may be from lake surface). |
| 1 |
|
obs_grav |
The observed, or measured value of gravity in mGals at an occupied gravity station.
In general, observed gravity varies from 978,000 to 984,200 mgals; therefore, many
data contributors subtract a large constant from 900,000 to 982,000 from this field.Note
that a constant of 978,000 mgals has been removed from the obs_grav values and that
they are referenced to the IGSN71 datum. |

|
secondary_dist_m |
The secondary_dist_ft variable converted to meters. From DMA. |
| 1 |
|
obs_grav_sd |
The standard deviation associated with the observed gravity value. |
| 1 |
|
Free_air_anom |
The anomalous gravity difference between an observed value and theoretical value.
The gravity data has been corrected for latitude and elevation (free-air correction),
but not for the density of the rock between datum and the plane of measurement (Bouguer
correction).Note that the gravity anomaly calculations were computed using the GRS67
model. |
| 1 |
|
Free_air_anom_sd |
The standard deviation of the Free-air Anomaly. |
| 1 |
|
terr_corr_total |
The terrain correction is an adjustment to the simple Bouguer correction that accounts
for variations in terrain above and below the elevation of the gravity station at
distances away from the point of measurement. Terrain below and above the level of
the theoretical horizontal slab used to make the simple Bouguer correction results
in a mass deficiency or excess that always yields an erroneously low gravity measurement.
As a consequence, the terrain correction is always added to the simple Bouguer correction.
The total terrain correction is the sum of the inner and outer zone terrain corrections
described above. |
| 1 |
|
terr_corr_sd |
The standard deviation associated with the terrain correction. |

|
source_id |
A numeric code for the contributing author or organizations of the data. |
| 1 |
|
station_char_code |
An alphanumeric code which indicates the type of elevation used in reducing the measured
gravity to anomaly values. Generally, elevation of land gravity station, if ocean
measurement, then ocean depth positive downward from surface. In some situations this
may represent instrument or bottom depth, ice thickness or alternative sea-level distance
measurement. From DMA. |

|
proprietary_code |
A numeric code denoting whether a gravity data record is: 1)not proprietary data (unmonumented)
code=1, or 2)not proprietary data (monumented) code=3Unique to the NGS93 data set. |
