Multi-parameter observations from coastal waters to the deep sea: focus on quality control and sensor stability

摘要

Decades of technical development in electronics, telecommunication, optics and acoustics measuring techniques have opened new possibilities for multi-parameter monitoring of the marine environment. This conference paper will give examples on how fixed multi-parameter platforms are used in a wide variety of applications ranging from shallow coastal on-line observatories down to measuring in the deepest Ocean trenches. Focus will be on long-term (years) stability and the challenge to maintain satisfactory quality control throughout the deployments.
