Industrial meteorologists work on air pollution, smoke emissions, etc. Climatologists collect, analyze, interpret and summarize past weather information to discover weather patterns. Hydrologists often work in meteorology, studying and forecasting floods and river flows. Aviation forecasters help air traffic controllers adjust air traffic to weather conditions. There are also fire forecasters, avalanche forecasters, agricultural and severe storm forecasters, and others.
Meteorological technicians make weather observations in the field and operate equipment.
Electronics technicians maintain electronic equipment. Marine geochemists investigate the chemical composition of seawater and its interaction with the atmosphere and the sea floor. Geophysicists explore the ocean floor and map geologic structures, like undersea volcanoes and mountain chains. They also study the physical and chemical properties of rocks and sediments. Physical oceanographers investigate the physical aspects of the ocean, such as temperature, density, wave motions, tides and currents.
