Topic: The Role of Marine Carbon Dioxide Removal in Addressing Climate Change
Goal: Simulate the efficiency of Ocean Alkalinity Enhancement (OAE) in the Pacific Ocean and investigate the OAE efficiency varies regionally and seasonally and how different ocean processes impact the OAE efficiency.
Motivation:
- The carbon emission reduction alone will not be enough to keep global temperature below dangerous levels (1.5 Celsius with respect to pre-industrial levels).
- PA middle of the road scenario for keeping global warming below 1.5 Celsius requires capture of >400 Gt of carbon dioxide by 2100.
- Several carbon removal approaches exist: (1) direct crabon capture, (2) cloud whitening, (3) aerosol injection, (4) nature-based approaches, etc.
- Marine Carbon Dioxide Removal (mCDR) is a nature-based approach. mCDR targets and accelerates natural sequestration processes and does not compete for space for other land uses.
Datasets:
- Location: /home/jovyan/shared/NASA_Summer_School/marine_co2/data/
- Forcing data for rapid-mCDR model simulation: rapid_mcdr_inputs
- Results of rapid-mCDR for 3 different OAE deployment approaches: rapid_mcdr_outputs
Scripts:
- Location: /home/jovyan/shared/NASA_Summer_School/marine_co2/
- model_v1.py: rapid-mCDR model
- run_rapid_mcdr_transect.ipynb: reads the forcing files, design OAE experiments and run rapid-mCDR model.
- plot_rapid_mcdr_transect.ipynb: reads the results of rapid-mCDR and make sample plots.
Geographic focus: A transect in the Pacific Ocean
Questions:
- What regions are associated with the highest OAE efficiency (most CO2 removed from the atmosphere per unit of Alk added to the surface ocean)?
- How fast is CO2 removed from the atmosphere after OAE deployment?
- How does the OAE efficiency change with the season of OAE deployment?
- How do different ocean processes impact OE efficiency?
