Hello bluesky! I am so happy to share that some of my Antarctic work was published today in BG: bg.copernicus.org/articles/21/.... This paper is seven (!) years in the making! Zinc is an essential micronutrient for phytoplankton, and is uptaken rapidly (biogeochem modelers please take note!)

I’ve been told that the more people like a feed, the more visible it is so please like the Oceanography feed even if you hate the ocean. 🌊🧪

"The ocean produces 50% of the oxygen we breathe" is a common misconception. While the ocean is responsible for about 50% of the planet's oxygen production, most of it is consumed by marine life, leading to a net production of close to 0. 🌊
