The new atlas provides high-resolution maps of the two major, oxygen-starved bodies of <a href=\"https:\/\/phys.org\/tags\/water\/\" rel=\"tag\" class=\"\">water<\/a> in the tropical Pacific. These maps reveal the volume, extent, and varying depths of each ODZ, along with fine-scale features, such as ribbons of oxygenated water that intrude into otherwise depleted zones.<\/p>\n<p>The team used a new method to process over 40 years\u2019 worth of ocean data, comprising nearly 15 million measurements taken by many research cruises and autonomous robots deployed across the tropical Pacific. The researchers compiled then analyzed this vast and fine-grained data to generate maps of oxygen-deficient zones at various depths, similar to the many slices of a three-dimensional scan.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Life is teeming nearly everywhere in the oceans, except in certain pockets where oxygen naturally plummets and waters become unlivable for most aerobic organisms.
