Geomagnetists are responsible for studying the Earth’s magnetic field and its variations over time. They use a variety of techniques to collect data on the magnetic field, including ground-based magnetometers, satellites, and aircraft. Geomagnetists use their data to create models of the Earth’s magnetic field, which can be used for a variety of purposes, such as navigation, surveying, and mineral exploration.

1. Collect and analyze data on the Earth’s magnetic field

Geomagnetists collect data on the Earth’s magnetic field using a variety of techniques, including ground-based magnetometers, satellites, and aircraft. Ground-based magnetometers are used to measure the magnetic field at a single location, while satellites and aircraft can be used to measure the magnetic field over a large area.

• Operate and maintain magnetometers to collect data on the Earth’s magnetic field
• Analyze data on the Earth’s magnetic field to identify patterns and trends
• Create models of the Earth’s magnetic field based on the data collected

2. Develop and use models of the Earth’s magnetic field

Geomagnetists use the data they collect to create models of the Earth’s magnetic field. These models can be used to predict the magnetic field at any given location and time. The models are also used to study the Earth’s interior and to understand the processes that generate the magnetic field.

• Develop and use mathematical models of the Earth’s magnetic field
• Use models of the Earth’s magnetic field to predict the magnetic field at any given location and time
• Use models of the Earth’s magnetic field to study the Earth’s interior and the processes that generate the magnetic field

3. Use the Earth’s magnetic field for practical applications

Geomagnetists use the Earth’s magnetic field for a variety of practical applications. For example, the magnetic field can be used for navigation, surveying, and mineral exploration. Geomagnetists also work with engineers to design and build equipment that uses the Earth’s magnetic field.

• Use the Earth’s magnetic field for navigation, surveying, and mineral exploration
• Work with engineers to design and build equipment that uses the Earth’s magnetic field
• Educate the public about the Earth’s magnetic field and its importance
