Sea ice controls net ocean uptake of carbon dioxide by regulating wintertime stratification - Communications Earth & Environment Interannual variability of ocean uptake of carbon dioxide is governed by winter sea ice cover, according to analysis of carbonate chemistry observations along the West Antarctic Peninsula.

📢 New paper alert! 📢

New insight into how sea ice controls the ocean uptake of carbon dioxide around Antarctica, obtained from the unique year-round Rothera Time Series.

Delighted to be part of this study, led by the very excellent Elise Droste.

No sunrise today down where we are in #Antarctica but the moon shone bright and we caught a beautiful brittle star! ❄️🥼🧪

The view last night over William Glacier felt very special

Antarctic glaciers export carbon-stabilised iron(II)-rich particles to the surface Southern Ocean Nature Communications - Authors show that Antarctic glaciers deliver high particle loads to the ocean, rich in iron that is potential food for marine algae. Microscopy techniques reveal this iron...

📣 New paper! 📣

Delighted to have led a fab team on a new paper out in Nature Comms!

Iron is an essential yet scarce nutrient for phytoplankton.

We find iron delivered by glaciers is transported across the Antarctic shelf and interacts a lot with carbon

This way to the ship! 🚢

There’s home for a month, as we sail to the West Antarctic Peninsula in the name of science 🧪🥼🌊. We boarded today in Punta Arenas, Chile, the world’s southernmost city! Sunrise 🌅 was at approx 09:30am

Very excited to be joining Mike on a potentially pretty chilly winter expedition to Antarctica today.

Updates to come on just how much daylight / ice / frozen fingers we experience! And of course, on all the ❄️cool❄️ biogeochemistry we get up to!

New paper on ocean mercury cycling! 🌊🧪

Mercury is toxic to marine life 🪱🐟🐋 and accumulates up the food chain. We find mercury is efficiently buried in shallow shelf environments, with implications for the impact of mercury in seawater globally.
