We interpret dissociating methane hydrates as the most likely cause of gas release. Dissociation of gas hydrates at the deep-water BGHS is dominantly the result of pressure decrease, which is greatest at peak stage glaciation, due to the accompanying ~120 m drop in sea-level. The pressure effect is potentially enhanced by the coincident arrival of warm temperature http://onlinelibrary.wiley.com/doi/10.1029/2010GL045184/pdf http://www.ocean-sci.net/10/29/2014/os-10-29-2014.html The increased southward flow of warm waters is balanced by a decrease in the southward flow of lower North Atlantic deep water below 3000 m. The transport of lower North Atlantic deep water slowed by 7% per year (95% confidence that the rate of slowing is greater than 2.5% per year).
