DELOS - Deep-ocean Environmental Long-term Observatory System

The DELOS project aims to increase our understanding of the deep water areas that BP are gradually extending into and provide long term environmental monitoring to enhance deep sea scientific research.

Two platforms were deployed in February 2009: one within 50 metres of a sea floor well (DELOS A, near field); and a second 16 km from any sea floor infrastructure (DELOS B, far field). These platforms are situated off Angola, in the Atlantic Ocean in the oil and gas exploration region termed Block 18 at a depth of 1400 m. The platforms will be deployed for 25 years and serviced annually by ROV. Long term monitoring by the DELOS platforms aims to:

Determine long term natural environmental conditions at the deep water site in Angola Block18:

  • Comparison of any changes observed at the near and far field monitoring sites
  • Increase understanding of mechanisms linking climate change to deep water ecology
  • Measure and monitor deep-sea biological communities
  • Understand the pace of recovery from any unforeseen impacts
  • Differentiate between natural and man made changes providing a linkage between marine biodiversity and climate change

Determine long term effects of the monitoring platform itself on natural processes

  • Understanding reef effect of large fixed structures in a deep water environment
  • Contributing to understanding of potential effects of sub-sea equipment in general

Contribute to individual & institutional capacity development in Angola

  • Working with Angolan Scientists in international collaboration
