SOCCOM supercool research featured in Nature highlight, podcast

In a new paper in Geophysical Research Letters, SOCCOM researcher Alex Haumann and colleagues used rather sparse traditional ship‐based observations with data collected by autonomous floats and instrumented marine mammals to detect and analyze where, when, and how supercooled seawater forms in the Southern Ocean. They detected sinking supercooled plumes from sea‐ice formation, which may be important for cooling the deep ocean and transporting constituents such as carbon, nutrients, or oxygen from the ocean's surface to deeper layers.
