📢 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.

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.

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
The view inside Börgen Bay, Antarctica. We are collecting water samples to understand how glaciers and the ocean influence each other in winter.

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

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...

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!

Guess where I’m heading today….!
Excited for a winter expedition to Antarctica. (Forecast was from a few days ago; I’m hoping it wont be quite this cold…though the chance of sunshine is kind of small this time of year…!🤣)
Wish me luck…!

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.
