Spectroscopy for the Earth

Commemorating Earth Day 2016

Air Quality ImageYou don’t have to be an environmentalist to appreciate the role of science in helping to understand, shape, monitor and predict the behavior of our planet. And so, in acknowledgement of Earth Day 2016, we celebrate how spectroscopy is used for various applications focused on the Earth and its inhabitants.

Spectral instrumentation has been used to address environmental applications such as open-path air quality monitoring in cities, sulfur dioxide analysis in volcanoes, and coral reef fluorescence as an indicator of ocean health. Also, spectroscopy has helped in the development of sustainable energy technologies such as photovoltaics and biofuels, where parameters can be monitored under conditions that match anticipated usage conditions.

Ocean Optics Spectrometers and “Earth” Applications

The name “Ocean Optics” was inspired, in part, by the U.S. Department of Energy Small Business Innovation Research grant that gave the company its start. The research funded by that grant involved making spectroscopic measurements of pH in the ocean.

Since then, Ocean Optics spectrometers have been part of numerous applications related to the environment. Here is a sampling:

Air and Water Quality
