What are the sources of data that geologists can use to understand the earth?
Existing cores, cuttings, well logs, maps, and seismic data are vital to those efforts. In addition, rapid advances in geologic, geophysical, and engineering science have occurred in the computer age.
How do geologists learn rock formations?
Others look for petroleum. Still others specialize in studying soil. Some geologists can tell how old rocks are and determine how different rock layers formed. Geologists might study rivers and lakes, the underground water found between soil and rock particles, or even water that is frozen in glaciers.
How do geologists use satellites?
Spectral data is collected by aircraft and satellites using infrared, near-infrared, thermal-infrared and short-wave technology. Geologists can use this data to pick out rock units and find clues about subsurface deposits of minerals, oil and gas and groundwater.
How did the geologists collect the data?
There are two main ways that the geologists collected data, through their own fieldwork and through reviewing information already available. Fieldwork involves collecting original data for the purpose of the research aims. A Desk Based Assessment (DBA) collects and summarises in a report information about a defined area, in this case the REC.
How are geoscience data and collections acquired?
The data and collections corporations hold are usually those acquired directly through their own activities or via purchase from other corporations. Private companies, in the form of independent repositories or data brokers, also collect and retain geoscience data and collections for sale or lease.
What is the job description of a geologist?
Depending on the particular specialization in geology, a geologist may study and map rock formations, collect rock samples and fossils, or measure the physical properties of the earth. This helps geologists interpret the active geological processes during the past several million years of earth’s history.
What is the importance of Geology in our daily life?
All divisions of geology provide highly useful information towards understanding the earth and its inhabitants. Depending on the particular specialization in geology, a geologist may study and map rock formations, collect rock samples and fossils, or measure the physical properties of the earth.
