👩‍🎓 PhD position at the National Oceanography Centre 👨‍🎓 🔍 Project: Heat, Freshwater and Oxygen Budgets in the Eastern Subpolar North Atlantic: Implications for UK continental shelf and European Weather. 🤝Team: Tiago, Neil, Lidia, & Bieito @bfcastro.bsky.social 🌊 Info: www.o-snap.org/phd-at-noc-uk/

What supplies nutrients to the surface layer of subtropical gyres is a long standing question in oceanography Recent work by Kate Oglethorpe shows that horizontal nutrient fluxes by mesoscale eddies are as (if not more) important than vertical fluxes: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

The Role of Mesoscale Eddy Stirring and Microscale Turbulence in Sustaining Biological Production in the Subtropical Gyres

Mesoscale eddy stirring and diapycnal mixing supply nutrients to the world ocean's subtropical gyres Mesoscale eddy stirring supply dominates over diapycnal mixing in the thermocline and plays a ...

Earth system models are plagued by uncertainties in the response of microbes to climate change. We leveraged metabolic insights from genome scale models when coupled to an ocean model in this new exciting work 🌊 www.science.org/doi/full/10....

Unveiling the link between phytoplankton molecular physiology and biogeochemical cycling via genome-scale modeling

A genome-enabled ESM built on genomic data assesses physiological acclimation and biogeochemical effects through nutrient stress.

Researchers modeled the paths of 100,000 particles of water backward in time over multiple decades to learn more about the origins of Subantarctic Mode Waters.

On the Origins of Subantarctic Mode Waters - Eos

A modeling study shows how warm subtropical waters and cold Antarctic waters combine to form an Indo-Pacific water mass that plays a key role in Earth’s climate.

The Greenland Sea is undergoing dramatic changes due to climate change, which has altered deep water production in the Northern Hemisphere. This is not just a regional issue—it has global consequences, especially for ocean circulation and carbon absorption.🧪🌊

POLEMIX will deploy a mixing observing system in the North Atlantic and feed the observations into ocean models to disentangle the fate of freshwater and its impacts on dense water formation. Hiring soon! @sotonoceanearth.bsky.social @nocmarinephys.bsky.social @imev-mer.fr @mitpress.bsky.social

Fernández Castro et al. (2024) find that mesoscale eddies play a dominant role in mixing heat and salt in the North Atlantic, helping us to better understand the Atlantic Meridional Overturning Circulation and its future behavior. 🔗 doi.org/10.1029/2023... #AGUPubs

Sea ice in the Arctic and around Antarctica cool our climate, drive ocean circulation across the planet, and provide a unique habitat for polar ecosystems. Sea ice amounts have now fallen to their lowest since we started measuring them. This is not good. 🌊🥼❄️🧪 www.bbc.co.uk/news/article...

The world's frozen oceans keep the planet cool, but they currently have less ice than ever recorded before.

A new paper led by Sebastian Sippel just appeared in Nature arguing that ocean temperature measurements in the early 20th century have a cold bias. It's a fun story illustrating the process of scientific discovery, so let me talk about it a bit. 🧵 www.nature.com/articles/s41...
