Oxygen Minimum Zones, or OMZs, are areas in the water column with less oxygen, primarily due to naturally occurring physical and biological processes within the Ocean. The core of the OMZ is anoxic, making them inhospitable to most large animals, yet microbes have adapted to live and thrive in this oxygen-starved environment. During the #OxygenMinimumMicrobes Expedition, an international team of researchers is working in the eastern tropical South Pacific off the coast of Chile. They strive to d
