A summary from the presentation. An introduction to molecular sensing in aqueous environments using different spectroscopic methods. For example, vibrational spectroscopy is a suitable tool for detecting hydrocarbons and corrosive substances dissolved in water while fluorescence techniques allow aromatic hydrocarbons and tracer dyes to be detected. Opportunities for future activities in the area of molecular sensing and sensor development are outlined.

This presentation highlights some of the results of research carried out using laser based spectroscopy including Infra-red and Fluorescence to Monitor hydrocarbons, tracers and other species in the marine environment. These can be used for detection and on-line monitoring and could be integrated in AUVs and ROVs. Some research areas for future collaboration with industry is presented.

University of Aberdeen. Principal contact:
Introducting the principles of laser induced breakdown spectroscopy; a means for atomic analysis of many materials with little or no preparation. This process has been widely implemented in shallow waters and in air, research at the University of Aberdeen is now intending to deploy this technique in deeper waters. Potential applications are sought in air, shallow and deep waters.

Dr. Radhakrishna Prabhu, Lecturer in School of Engineering,
Robert Gordon University; Contact
Introducing some of the optical and spectroscopic approaches for sensing and monitoring in subsea environments, including applications such as measurement & control and structural integrity monitoring. Also included are results from the current research work in the area of optical sensors and an outline of collaboration opportunities.

Professor John A Steel, Head of School of Engineering
Robert Gordon University; Contact
An overview of the results of research carried out in developing applications of Acoustic Emission which might be relevant to the monitoring, maintenance and management of subsea installations. Including are brief examples of applications such as machine monitoring, AE wave propagation in pipe lines, material testing, and sand monitoring. The examples range from fairly mature applications to some possible new applications. Some research areas for future collaboration with industry are outlined.
Alastair Allen-Dynamic UWSN-Subsea 2012
Dr Alastair Allen, School of Engineering
University of Aberdeen; Contact
Subsea industries face a number of technical challenges in the area of remote sensing and control. By bringing together the technologies of underwater communications and results from terrestrial sensor networking, the development of underwater wireless sensor networking (UWSN) promises solutions to many of these problems. Underwater sensor networks may include both static and mobile sensors: these may join and leave sensor groups dynamically. A number of gaps in the existing UWSN research are identified and solutions are proposed which include efficient network routing protocols and dynamic reconfigurability.

The high deformation rate and surface area of solidus or liquidus foam can be employed as a large scale sensor for various sensing modalities. The magnetic nano-particulate stabilised micro-foam prepared at RGU has demonstrated its capability as a gas leakage detector and a pressure sensor. In this presentation, results are outlined that show its possible use in the subsea environment. The future direction for developing sensor based on nanotechnologies is also summarised.

A presentation of precision sensing of gravitational and magnetic forces in a portable compact sensor being developed in the S3C Lab at Aberdeen. The technology is based on recent advances in laser and quantum atomic optics and offers improved sensitivity, compactness, mobility and lower power consumption. It should make possible the deployment of precision sensors in subsea environments for applications in survey and inspection underwater using AUVs and ROVs.
