Sampling bottles sinks into the waters of the Eastern Tropical North Pacific, one of the ocean’s largest oxygen-starved zones. Researchers aboard the vessel used this device to collect seawater at precise depths, capturing microbes that turn common nutrients into nitrous oxide—a greenhouse gas roughly 300 times more potent than carbon dioxide.
