MeDON Phase II - Outline MeDON Partners Meeting, Plymouth. March 8 th 2012 Chris Gallienne, PML An initial investigation of potential development of MeDON Phase II project proposal with the principal aim of developing a sub-sea cabled observatory in the Plymouth area to match, complement and build upon the developments under phase I in Brest.
Proposed location of phase II Plymouth Sound Special Area of Conservation (SAC, shaded) Strictly protected sites designated under the EC Habitats Directive. Potential phase II sites at Penlee Point and Wembury Bay Penlee Point Wembury
Proposed location of phase II – Wembury Bay Wembury Bay: Very sheltered location Wembury Marine centre a useful potential partner providing outreach potential No suitable shore station location. Distance is 6.8km (3.7nm). No line of sight to PML Temporary building, power generator & GSM connection required?
Proposed location of phase II – Penlee Point Penlee Point: Line of sight exists between Penlee Point and PML. Distance is 5.8km (3.1nm). We can use the Ubiquiti wireless ethernet system. Existing building can house shore station, provide power. Trinity House own & run this site – they have expressed an interest in MEDON II MOD interest in this area – potentially a useful partner.
Proposed location of phase II Penlee point control building
Proposed location of phase II Line-of-sight to PML
Proposed general topography of phase II Outline design A small pilot cabled sea- floor sensor network to monitor marine ecosystem state and processes. A backbone cable will provide power and communications between a wired network of small, low-power purpose built sensor units and a shore station. From there it will connect to PML intranet using Ubiquity wireless ethernet.
Proposed development of phase II Development potential The system will be designed to be modular and portable. This will enable redeployment in response to incidents such as pollution events. This may also present opportunities to take advantage of developments in offshore power generation installations as hosts for and collaborators in the development of small cabled observatories.
Initial estimation of costs for phase II Basis for costing: The proposed project has a rather high proportion of costs in equipment and infrastructure installation which are difficult to estimate prior to a detailed initial design study in collaboration with external partners. Pending such a discussion, the estimate of costs is therefore given with a wider than usual degree of uncertainty. Initial estimates: Equipment: £ M; Staff: £ M; Ship time: £ M; Other: £0.32M; Total: £1.4 – 2.0M. Funding to be requested: £1.12 – 1.60M
