That Bruce from an interactive #GoogleDoodle celebrating #MarieTharp work, who deleted her work and instructed her to redo everything was actually really stupid.
It makes you wonder where we would be scientifically if the Bruces of this world had believed more in women. -
Ocean oxygen: The role of the Ocean in the oxygen we breathe and the threat of deoxygenation | New report of the European Marine Board
#Deoxygenation is increasing in the coastal and open Ocean, primarily due to human-induced #globalwarming and nutrient run-off from land, and projections show that the Ocean will continue losing oxygen as global warming continues.

It would be really very cool to make #BiodiversityStripes for #marine #biodiversity. Like these ones for #freshwater #species from https://findingnature.org.uk
The #ocean #ecosystems are getting weaker due to #ClimateChange, #OceanAcidification, #Deoxygenation, #Overfishing.
There are robust #datasets for different marine species around, aren't there?

How does Earth breathe CO2 under different #ClimateChange scenarios?
Have a look at this visualization showing seasonal variations of atmospheric CO2 modulated by anthropogenic emissions and the strength of the ocean and land carbon sinks.
Computed with an #EarthSystemModel #MPI-ESM.

Exciting news :thinkhappy: 📰
Our #manuscript presenting an application of coarse-grained component #concurrency for #ocean #biogeochemistry has been accepted for publication.
https://gmd.copernicus.org/preprints/gmd-2022-214/
Let me #decipher what this is 🤯
In an #EarthSystemModel, the #uptake and #storage of #CO2 in the #ocean is computed by the embedded ocean #biogeochemistry models. 1/

The paper presents a new model ICON-Coast that uses a telescoping #HighResolution for an improved representation of the #coastal #ocean #CarbonCycle #dynamics.
#Global #models fail to capture coastal zones due to coarse resolution. #Regional #models struggle to realistically represent the #coastal - #OpenOcean interactions.
#Seamless #integration presents new opportunities.

The most computationally expensive part of such models is the transport (by #advection and #diffusion) of #biogeochemical #tracers (zoo and #phytoplankton #nutrients, organic and inorganic #carbon, etc) with the #ocean #flow.
The more tracers we include to represent the complexity of #ocean biogeochemistry, the slower are the model runs. Same problem arises when the #spatial #resolution of an #ESM increases.
Biogeochemistry models can become a bottleneck in #ESM computations. 2/

Please spread this #Job Opening in my group at Universität #Hamburg: Postdoctoral | #Research Associate in the Project “CAP7”.
The focus is to enhance the representation of ocean biogeochemical processes, carbon-climate feedbacks, and ocean carbon storage under changing emissions in the new generation #EarthSystemModel ICON-XPP.
These novel simulations will contribute to #CMIP7 and the next #IPCC assessment of #climatechange.
See how to apply 👇

Acceleration of #climatechange is taking place due to our failure to cut increasing CO2 emissions.
Any impact of Arctic coastal #permafrost erosion on the global #climate through increasing atmospheric CO2 concentrations until 2100 is comparatively small.
Yet, this new #EarthSystemModel component allows for a better quantification of the carbon budget, necessary for carbon monitoring under #decarbonisation .

In a #newpaper from my group, led by David Nielsen, we incorporated coastal permafrost as a new component of an #EarthSystemModel.
This allowed us to quantify that #coastal #permafrost erosion weakens the Arctic Ocean #CO2 uptake from the atmosphere by 7-14%.
This exerts a positive biogeochemical feedback on #climate, increasing atmospheric CO2 by 1–2 TgC yr−1 per °C of increase in global surface air temperature.

What happens after a snowball Earth melts?
With the new #EarthSystemModel ICON, we find that the supergreenhouse climate was not necessarily a stable and hot climate over hundreds of thousands of years. It is also possible that the temperatures were moderate and even declined rapidly, on a time scale of just a few thousand years, in response to changes in the ocean C-cycle.
Find out in this news piece👇

Once upon a time, only about 650 million years ago, our Earth was a snowball. What was the aftermath #greenhouse #climate triggering deglaciation and the ocean's role in it?
We addressed this intriguing scientific question via a set of #EarthSystemModel experiments in the new Nature Communication paper "Moderate greenhouse climate and rapid carbonate formation after Marinoan snowball Earth" led by Lennart Ramme within his PhD project.

Have a look at our simulation of the air-sea #CO2 flux and surface wind speed in a high-resolution #EarthSystemModel model ICON 👇
https://youtu.be/63NZSPjxv6wI find September particularly fascinating in this animation. A hurricane in the Western Atlantic entirely messes up the CO2 flux. Here, the immediate effect is that the hurricane enhances the outgassing of CO2. Behind it, the flux swaps the sign and there is uptake of CO2.

With my group, I study a #CDR method of artificially increasing ocean C-sink by adding alkalinity.
In an #EarthSystemModel
large amounts of alkalinity boost the oceans' capacity to absorb CO2.
This comes at a price of unprecedented perturbations in #biogeochemistry with unknown implications for marine life.Learn more in our papers

There is a striking difference between land- and ocean-based #CDR.
Ocean CDR ideas like adding #alkalinity or artificial upwelling imply unprecedented intervention into ocean commons, with unknown impacts on ecosystems. #Monitoring, not to mention regulating, would be practicably challenging, because ocean waters move.
Land carbon cycle is already managed by agriculture, urbanization etc. Land CDR would be a mean of already ongoing carbon rebalancing.
