Regulation of ice stream flow through subglacial formation of gas hydrates
in Nature Geoscience
Description | We've found that the subglacial hydrological system beneath the GrIS evolves seasonally to effeciently encompass increased volume of melt-water. This result in a contrasting flow response of the ice sheet in marginal areas - where early summer acceleration is compensated by late summer/winter slow-down, whilst interior regions of the ice sheet (above the long-term ELA) appear to be undergoing long-term acceleration. |
Exploitation Route | The project developed a unique chemical tracing system for investigating subglacial environments. |

Results and Impact | Our Planet (A WWF & Silverback Films collaborative documentary series commissioned by Netflix) is a 6 part flagship doco. Global viewing figures are 15M+. As part of Greenland outreach activity connected with NERC/RCUK research on the Greenland ice sheet, Alun Hubbard advised and consulted on many aspects of the Greenland sequences including expert advice on the Store Glacier calving sequence - considered the highlight of Epsiode 1. |
