Why in news
Scientists are evaluating the 'Seabed Curtain Project' as a geo-engineering intervention to stabilize the Thwaites Glacier in West Antarctica against melting.
Background
The Seabed Curtain Project proposes an 80km long and 150m high underwater barrier to divert warm ocean currents. A South Korean expedition installed ocean moorings between January and March 2026 to collect data on current behavior.
Facts for Prelims
- PlaceThwaites Glacier: Located in West Antarctica, often referred to as the 'Doomsday Glacier'.
- FactSeabed Curtain Project: Proposed barrier dimensions are 80km in length and up to 150m in height.
- FactProject Cost: Estimated between US $40 billion and $80 billion.
- FactTimeline: Data collection from ocean moorings conducted between January and March 2026; results from Svalbard fjord tests due by September 2026.
- S&TGeo-engineering: The project aims to mitigate sea-level rise by physically obstructing warm water currents.
For Mains
Q. Critically analyze the feasibility and ecological risks of large-scale geo-engineering interventions like the Seabed Curtain Project in addressing global sea-level rise.
Dimensions to cover in your answer
- Ecological disruption: Potential alteration of deep-sea marine ecosystems and nutrient cycling by physical barriers
- Economic viability: High capital expenditure ($40-80 billion) vs. the long-term costs of unmitigated sea-level rise
- Geopolitical liability: Legal and environmental accountability for unintended consequences of large-scale oceanic geo-engineering
Keywords: Geo-engineering · Cryosphere stability · Anthropogenic climate change · Marine biodiversity · Sea-level rise
