First time-lapse monitoring of fjord-deltas using new technology

Research

Submarine gravity currents are one of the most important processes of moving sediments across our planet. However, direct monitoring of these flows has proven difficult due to their inaccessible, unpredictable and destructive nature. My research at Durham University utilises one of the first ever direct and detailed monitoring data of these underwater flows. There are two different test sites:

  • Bute Inlet, Canada
  • Monterey Canyon, USA.

Methods

Multiple moorings with Acoustic Doppler Current Profilers (ADCPs) were deployed for 6 months at Bute Inlet, and for 18 months in total in Monterey. Using Matlab, the ADCP data is analysed by looking at front flow properties, flow velocities, and flow intensity. This data is compared to internal and external flow parameters. 

In addition, this research will include analysis of sediment cores obtained in Bute Inlet, and flow modelling at NGI, Oslo.
