Postdoctoral Research Associate in Global Seafloor Listening Network Based on Hydrophones

Durham University - Department of Earth Sciences

Location: Durham
Salary: £33,199 to £39,609
Hours: Full Time
Contract Type: Fixed-Term/Contract
Placed On: 6th June 2019
Closes: 24th July 2019
Job Ref: 018602

Closing Date: 24 July 2019 (Midday)

Applications are invited for a Postdoctoral Research Associate that is part of a major international project to develop a novel low-cost listening network for the seabed. Specifically, this 20-month Postdoctoral Research Associate will seek to determine how powerful and hazardous seafloor avalanches of sediment (called turbidity currents) are recorded by submerged hydrophones and geophones. These seafloor flows form the largest sediment accumulations on Earth, and they often break seafloor cable networks that now carry over 95% of global internet and other data traffic.

This Postdoctoral Research Associate will first analyse new hydrophone and geophone data from a series of major ocean-going research cruises to the Congo Submarine Canyon located offshore West Africa. Second, they will also analyse previously collected hydrophone data from other locations worldwide, including a series of fjords offshore Vancouver in Canada, and Monterey Canyon offshore California. Having better understood the signal of such seafloor flows, they will then work with the wider project team to help design the next generation of low-cost hydrophones for seabed sensing, which return data to base via novel technology. The ambitious project has been funded by two major National Environment Research Council (NERC) grants, and involves a wide range of UK and international partners and research cruises.

This post is full time & fixed term for 20 months.
