Airborne Gravity has been primarily developed for petroleum exploration as a cost-effective alternative to terrestrial and marine surveys. The learning objective guides you through an introduction that encompasses everything from the types of instruments used to survey design, data processing, and quality control.

The course begins with the advancements in instrumentation and navigation technology that have made airborne gravity a viable method for data acquisition. Instruments aboard aircraft can now measure the Earth’s gravitational field strength with an accuracy level of 1-2 milligals.

This high level of precision means that scientists can use aircraft to collect reliable data for mapping minute variations in the gravity field, which are a million times smaller than the standard gravity value of 1 g°. Such detailed mapping capabilities are crucial for locating subsurface resources and facilitating high-precision geodetic applications.

Environmental Science encompasses the air we breathe, the water we drink, the soil we tread upon, the temperatures we experience, the radiation we are exposed to, the decisions we make, and the consequences we face.

The emphasis has initially been on regulatory processes, which cover topics such as environmental assessment of properties, occupational safety, and the monitoring and management of air, water, and waste. Outcomes are continuously identified, their causes investigated, and regulations consequently revised.

The discipline involves four primary steps: 1) basic research, 2) applied research, 3) regulation, and 4) outcomes. These steps are interdependent and not strictly sequential, as each aspect can influence the others.

Gravity Gradiometry involves studying and measuring the variations in gravitational acceleration. It is utilized by oil and mineral prospectors to gauge the subsurface density, essentially measuring the rate of change in rock properties. This data enables the creation of a subsurface anomaly map, which aids in the precise targeting of oil, gas, and mineral deposits.

Gravity gradiometry is utilized to image the density of water columns, locate submerged objects, and ascertain water depth (bathymetry).

Physical scientists employ gravimeters to ascertain the precise size and shape of the Earth, contributing to the gravitational compensations applied in inertial navigation systems.

Radiometrics, also known as airborne gamma-ray spectrometry, began in the late 1960s with its initial application in uranium exploration. From the mid-1970s onward, this method has been widely used to aid in geological mapping and mineral exploration.

Radiometrics is employed to detect and measure the dispersion of both natural and artificial gamma-emitting isotopes in the vicinity of nuclear power plants. This process assesses the radiation dose’s impact from the plant on the public.

Airborne gamma-ray spectrometry is utilized for environmental monitoring and mapping as well. Data on natural and anthropogenic radiation are collected using gamma-ray spectrometers installed on fixed-wing aircraft, helicopters, and through ground surveys with appropriate vehicles.

Potential Fields (PF), particularly gravity and magnetics, indicate that the signature (anomaly) of a magnetized body has both a minimum and a maximum, altering its shape according to its geographic position relative to the Earth’s magnetic field. Consequently, the initially measured fields require correction based on geographic location.

Once the magnetic field has been corrected, interpreting geological structures becomes more straightforward as their signatures—or anomalies—are directly related to the size, shape, depth, and magnetic susceptibility of the different bodies.

Geological and Geophysical (G&G) Applications, particularly geologic and geophysical modeling, involve the applied science of developing computerized models of the Earth’s crust. These models are constructed from geophysical and geological observations gathered on and beneath the Earth’s surface.

A Geomodel represents the numerical counterpart of a three-dimensional geological map, enriched with a description of physical quantities within the domain of interest. Geomodelling is associated with the concept of a Shared Earth Model, which serves as a multidisciplinary, interoperable, and updateable knowledge repository concerning the subsurface.

Geomodelling is commonly used for managing natural resources, identifying natural hazards, and quantifying geological processes with main applications to oil and gas fields, groundwater aquifers and ore deposits.

The Organic Chemistry Tools Series is centered on teaching techniques essential for the successful completion of a university’s undergraduate laboratory classes. It features short videos that cover a range of topics.
