Description:

Abstract:

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. This dataset presents latitude, longitude, altitude, and magnetic-field values.

Purpose:

Aeromagnetic surveys are used for geophysical prospecting. Some variations in magnetic measurements are caused by rocks that contain significant amounts of magnetic minerals (magnetite being the most common). These anomalies reflect variations in the amount and type of magnetic material and the shape and depth of the body of rock. Aeromagnetic anomaly maps are important tools in mapping surficial and buried igneous rocks. The features and patterns of aeromagnetic anomalies can also be used to delineate details of subsurface geology including the locations of buried faults and the thickness of surficial sedimentary rocks.

Supplemental_Information:

The U.S. Geological Survey has contracted or flown numerous airborne surveys over a long period (1950's to present). Not all flight-line data have been released to the public because of lack of personnel to reformat data and service the requests. With the improvement in digital communication and the ability to store and transmit large data sets, the USGS is now able to release the flight-line data in a common format. A companion CD-ROM/web site has been released containing magnetic data that were generated by digitizing analog maps. Digital flight-line data used to create the analog maps are unavailable. Reference is in the Cross-Reference section of this metadata file.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The data in this file have been processed using various formulas and methods that are not usually documented but that represent industry standard practices for airborne data reduction. For example, position is listed as latitude and longitude, but these values were derived from the raw navigation data depending on the system used. (see notes under horizontal accuracy). Line numbers were added to records, and unusable data at flight-line ends were discarded (as aircraft slowed and turned around). Separate recordings were correlated by time and assigned to the correct location. The exact accuracies of these processing steps may not be known. They are discussed in the sections on attribute or positional accuracies.

Logical_Consistency_Report:

The data in this file were collected by a single contractor or group who were responsible for collecting and processing the data. The data from this survey were collected using the same instruments (magnetometers, altimeters, navigational systems) throughout the survey and were collected in a normal length of time with no long delays between survey beginning and end. Survey contracts specified the conditions and specifications under which these data were collected. Standard industry practices of the time were followed in data collection and processing.

Completeness_Report:

Loss of data due to poor transmission, channel dropout, obvious spiking, missing channels, and other obvious errors were replaced with the value -9999.9. The values for total magnetics (totmag) were assigned from the original contractor channel containing values described as "diurnal + mean." The values in the residual magnetics (resmag) channel were calculated based on the totmag channel and an original contractor channel containing IGRF 1995 values (i.e. resmag = totmag - IGRF1995).

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Flight Path Recovery Horizontal position of the survey aircraft used to collect data were determined using GPS satellite navigation.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

The aircraft vertical position was determined using the navigational positioning equipment on the aircraft, which were radar altimeter and barometric altimeter. Radar altimeters are estimated to have an error of 2-5% of the altitude (Richard Hansen, PRJ, Inc., written communication). Barometric altimeters are quite accurate, but are typically operated in an uncorrected mode. The diurnal variation in air pressure over the course of a flight can produce a 50-100 ft error in the barometric altimeter reading. In addition, pressure microcells create short-period air pressure changes equivalent to about 10 ft under typical conditions (Richard Hansen, PRJ, Inc., written communication) The magnetometer was carried in a bird towed on a line that was approximately 148 feet below and 262 feet behind the aircraft. The bird as it is towed is slightly behind the aircraft and therefore the vertical distance between the magnetometer and the aircraft is slightly less than the length of the line but remains constant for the survey. This data set was collected at a draped survey having a average terrain clearance of 400 ft. Because aircraft, especially airplanes, cannot safely maintain a constant terrain clearance, error in vertical position is introduced.

Lineage:

Process_Step:

Process_Description:

Conversion of measured values to geographic position and magnetic values was performed by the contractor using industry standard practices. Details are found under Attribute Accuracy Report, Horizontal_Position_Accuracy_Report, and Vertical_Position_Accuracy_Report Unless noted, conversion processes were not reported to the USGS. Unpublished products generated by the contractor included magnetic tapes, a map of residual or total field magnetics, and perhaps some written documentation.

Process_Date: 1997

Process_Step:

Process_Description:

USGS reformatting of contractor data to standard format. USGS personnel used the software package Oasis Montaj version 4.3 by Geosoft, Inc., to read in the original contractor's data. Latitude, longitude, altitude, and magnetic values were checked for obvious errors or spikes and values of -9999.9 were given where the value could not be reasonably corrected. Other errors in the data were not corrected. Horizontal positions were converted to latitude and longitude if the original values were UTM meters. Elevations were converted from meters to feet (1 m = 3.2808 ft). Information was added that was missing from the data file but was recorded elsewhere. The reformatted data file was written in the format described in the section on Entity_and_Attribute_Overview.

Attribute:

Attribute_Label: totmag
Attribute_Definition:

Raw magnetic value with base magnetometer corrections applied. Because the magnetic field of the earth varies diurnally, a stationary base magnetometer is maintained on the ground during airborne surveying. The base magnetometer records changes in the magnetic field (in nanoTeslas) as a function of time. The magnetic changes may have an amplitude of 20 to 50 nanoTeslas. If changes are more severe, as would occur from a magnetic storm, surveying is discontinued or the data recorded are not used. Diurnal variations are then removed from the airborne magnetic data based on the common time. Values of -9999.9 indicate missing data.

Attribute_Units_of_Measure: nanoTeslas

Attribute_Value_Accuracy_Information:

Attribute_Value_Accuracy: 2
Attribute_Value_Accuracy_Explanation:

The airborne magnetometer is accurate to about 1 nanoTesla, and the base magnetometer has the same accuracy. The accuracy of the base-corrected airborne value therefore is near 2 nanoTeslas or better.

Attribute_Measurement_Frequency:

The magnetometer has a recharging interval of 0.5 seconds. The data were recorded at 0.1 second intervals.

Attribute:

Attribute_Label: resmag
Attribute_Definition:

residual magnetic value The total magnetic value minus a geomagnetic reference field (GRF), which is a long-wavelength regional magnetic field. The most commonly used reference field is determined from a model developed by the International Association of Geomagnetism and Aeronomy (IAGA). The International Geomagnetic Reference Field (IGRF), is a predictive model adopted at the beginning of a model period (e.g. in 1989 for 1990-1995). After the model period, a revised definitive model is adopted, the DGRF. This is the preferred model to use for removing regional magnetic fields. For this survey, the field removed was the IGRF 1995. Values of -9999.9 indicate missing data.

Attribute_Value_Accuracy_Information:

Attribute_Value_Accuracy: 2
Attribute_Value_Accuracy_Explanation:

The Geomagnetic Reference Field that was subtracted from the total magnetic value is based on a model, which was updated to the date of the survey. New models are available at five year intervals. These models have varying degrees of accuracy in determining the local reference field.
