Welcome enthusiastic MOOCers
Hello MOOCers,
I’m Eric, one of your facilitators in ‘Exploring our Oceans’ MOOC. I’m a first year PhD student in the field of Marine Electromagnetic Geophysics at the National Oceanography Centre. My project aims to image and quantify methane hydrates pockmark chimneys which are located offshore Norway, by using the University of Southampton Controlled Source Electromagnetic (CSEM) method.
In recent years, methane hydrates deposits have attracted growing interest from both academic and industry research, due to their potential as an unconventional energy resource, role in climate change and concern as a geohazard. That is attributed to the fact the gas hydrates spread worldwide along continental margins, while their estimated amount is greater than all other hydrocarbon resources combined.
In my research I use forward and inverse models in order to delineate and quantify the amount of free gas and methane hydrates in the Nyegga CNEO3 chimney and its immediate surroundings, as well as studying the methane hydrates layers at depth over a larger regional scale.
Future work will focus on the development of a joint seismic/electromagnetic tomography to better image methane hydrate pockmarks and understand the causes for hydrate dissociation from the seabed, to the water column and eventually to the atmoshpere.
