AGU Fall Meeting
I went to this year’s AGU Fall Meeting in Washington, D.C. It’s one of the largest geoscience meetings, with over 24,000 people covering a range of science, from geology, geophysics, space sciences, and oceanography. To get there from Boston, MA, I decided to take the train (the Acela Express, to be precise) rather than fly.…

Communicating climate change by making it personal
For greatest impact, it really helps to make something personal. Show your colleagues, friends, and family this interactive chart from Zeke Hausfather and CarbonBrief. It shows how much your, or their, home town has been impacted by climate change. For example, the area around Southend (near where I grew up in England) has warmed 1.2°C; South…

AWESOME Workshop
I was invited to speak about global ocean circulation and biogeochemistry models at a really cool Ocean Carbon and Biogeochemistry workshop in Cambridge, MA introducing the AWESOME-OCIM (A Working Environment for Simulating Ocean Movement and Elemental Cycling-Ocean Circulation Inverse Model) organized by Prof Seth John. The model is really customizable and uses linear algebra to allow…

Reflections on science and society, with Fridtjof Nansen
After the awesome US Ocean Carbon Biogeochemistry Group biogeochemical argo float workshop in Seattle, I went to the excellent Nordic Museum to see their exhibition about Fridtjof Nansen. Nansen was an ocean science pioneer. During expeditions aboard “Fram” he introduced “layered” clothing, invented a water bottle for sampling temperature and salinity, and noticed that sea ice…

Happy #WorldOceansDay and welcome to Seamantic Science.
The oceans cover over 70% of the Earth’s surface, so really, every day is World Ocean Day!
Read MoreThe impact of Southern Ocean residual upwelling on atmospheric CO2 on centennial and millennial timescales
This post is under revision at the moment, so I can write description of our results, sorry. I pasted the abstract below for now. The Southern Ocean plays a pivotal role in climate change by exchanging heat and carbon, and provides the primary window for the global deep ocean to communicate with the atmosphere. There…
Read MoreQuantifying the drivers of ocean-atmosphere CO2 fluxes
This post is under revision at the moment, so I can write description of our results, sorry. I pasted the abstract below for now. A mechanistic framework for quantitatively mapping the regional drivers of air-sea CO2 fluxes at a global scale is developed. The framework evaluates the interplay between (1) surface heat and freshwater fluxes…

This post is under revision at the moment, so I can write description of our results, sorry. I pasted the abstract below for now. Collaboration sometimes takes unexpected detours as I found working with colleagues at the University of Liverpool who take climate models, meteorological observations and disease forecasting systems and try to predict the…
Read MoreCarbonate ion concentrations, ocean carbon storage and atmospheric CO2
This post is under revision at the moment, so I can write description of our results, sorry. I pasted the abstract below for now. Reconstructing past ocean [CO3-2 ] allows the paleodepth of the chemical lysocline to be constrained, an important control on past atmospheric CO2. However, the causal mechanisms responsible for observed spatial and…
Read MoreWind-driven changes in Southern Ocean residual circulation, ocean carbon reservoirs and atmospheric CO2
This post is under revision at the moment, so I can write description of our results, sorry. I pasted the abstract below for now. The effect of idealized wind-driven circulation changes in the Southern Ocean on atmospheric CO2 and the ocean carbon inventory is investigated using a suite of coarse-resolution, global coupled ocean circulation and…
Read MoreClimatic variations of the work done by the wind on the ocean’s general circulation
This post is under revision at the moment, so I can write description of our results, sorry. I pasted the abstract below for now. The Southern Hemisphere westerlies exert an important influence on global climate, supplying nearly half of the mechanical energy for the deep overturning circulation. In a coarse-resolution ocean model, northward-shifted winds increase…
Read MoreIntensified turbulent mixing in the boundary current system of southern Greenland
This post is under revision at the moment, so I can write description of our results, sorry. I pasted the abstract below for now. The southern Greenland Deep Western Boundary Current (DWBC) advects major components of North Atlantic Deep Water. Turbulent diapycnal mixing rates of 10 4 m2 s 1 commonly occur in the DWBC.…
