Polar natural gas hydrates may be particularly sensitive to climate change as enhanced global warming takes place through polar amplification. Dissociating hydrates and the subsequence release of greenhouse gases further have the potential to contribute to the triggering of submarine landslides and drilling hazards.
The Atlantic Margin consists several hydrocarbon basins which have the potential for CO2 storage, including the currently operational Snøhvit and Sleipner CO2 aquifers offshore Norway.
We aim to develop an algorithm to calculate the methane and CO2 hydrate stability zone thickness and extent map along the Atlantic margin from Svalbard to Ireland, which will include updated geophysical and geochemical datasets.
We will address the impact of seasonality on gas hydrate stability zone extent and assess the impact of water column warming commonly associated with anthropogenic warming.
