Keeping a journal is an important part of any type of field work. And in many ways, it acts like a diary for scientists and engineers because it keeps track of information you have gathered while you’re on the field. As you work at a particular site, your field journal can give you a single place to store necessary information. Scientist may need to write measurements, data, observations, or information about specific specimens they have collections. But a surveyor or engineer may need to record measurements, draw quick sketches of a specific layout, or record any information related to a construction site.
