The objective of this study was to determine whether the water quality is suitable for mussel farming to be viable within Swansea Docks. Field sampling took place in the Swansea Docks in the period May-November 2011. Salinity and temperature profiles were recorded and water samples were collected at two depths at four different stations for the analyses of dissolved oxygen, dissolved nutrients, suspended organic carbon, nitrogen and chlorophyll.
It is widely recognised that the reduction of nutrients (mainly nitrogen (N) and phosphorus (P)) is necessary to improve the ecological quality of coastal waters. One suggested method for nutrient absorption is the use of xylit-fibres. The collaborative R&D project contained a laboratory study where the chemical and physical properties of the xylit-fibres were determined. In the laboratory the nutrient absorption of xylit-fibre rolls was assessed and compared with two other materials (fresh wood fibres and coir fibre), using water in mesocosms tanks.
The objective of this study in collaboration with a small marine environmental consultancy was to map the bathymetry of a proposed mussel farm and determine if the development of that farm based on natural spat fall in the area will be financially viable. The output of a bivalve aquaculture algorithm, the FARM model, was presented suggesting a financially viable yield of can be expected from this site assuming consistency of the physical and chemical parameters measured.
The Gower Heritage Centre in Parkmill has been the site of a flourmill since the 12thcentury. The infrastructure present in the centre provides the possibility for the generation of electrical energy using the water flow of the water wheel's leat. This project involved the measurement of water current at various points around the mill site using in situ impellers attached to bespoke logging systems as well as the measurement of drop heights of the mill leat to determine whether any of these energy generation schemes would be viable.
Increased information about the ecological resources in and around Skomer is required to help sustain the eco-tourism attraction value of Skomer to wildlife visitors. This project will provide DWT enterprises with key information about the economic and ecological value of the seagrass meadow at Skomer. This will be of particular value to visiting divers and snorkelers, but will also benefit those paying visitors interested in the value of the seagrass meadow as a source of food for seabirds.
Gower Wildflowers Ltd is a commercial enterprise based in the Gower involved with growing and selling plants and wildflowers. Due to their botanical expertise they are interested in developing capacity to commercially grow seagrass, Zostera spp. for large scale restoration projects throughout Europe. SEACAMS is providing Gower Wildflowers Ltd with applied research support to develop commercial production of Zostera spp.
Hydro Industries uses electrochemical techniques to remove contaminants from waste water on medium to large industrial sites around the world. These processes have involved the use of electrolyses to remove contaminants from waste water thus allowing the discharge of clean water to the environment. Hydro Industries propose to develop this technology to act in a different way; that is to use the electric field set up in the electrolysis process to rupture the cell wall of pathogens, therefore allowing the sterilisation of sewage discharges without the requirement of adding toxins such as chlorine, and at a lower energy cost than using currently available sterilisation techniques, i.e. ultraviolet sterilisation.
Anti bacterial properties of AM500 have been demonstrated for several species and it has been shown to be an effective antibacterial coating of surfaces. SEACAMS is investigating whether or not Vibrio species of bacteria are inhibited in a small water body when the container that water is in is coated with AM500. This group of bacteria is of high importance in the aquarium industry as it causes mortality in a number of species and enters the system through cultured feed stocks. The aim of this project is to demonstrate the effectiveness of AM500 against Vibrio species.
This applied research project is providing Waterline , Llyn Adventures and the National Trust with site specific information about the ecosystem service role of the seagrass meadow at Porth Dinllaen. This information will provide information for the potential development of programmes aimed at attracting tourists to utilise the seagrass meadow for snorkelling and to visit the rocky shore to see the interesting fauna. The information will also contribute to the stakeholder engagement process that aims to change mooring and anchoring practice and improving its environmental management.
Probability One, a remote sensing consultancy based in Abercynon, would like to investigate whether remotely sensed images may be used to map the extent and estimate the intensity of metal contamination in vegetated floodplains. The commercial potential of such technology is global, as governments around the world struggle to identify and manage contaminated land.
Worldwide water sports is a jet ski/small boat sales and servicing company based in Bridgend. It leases an area of water and waterside property from Associated British Ports in Llewellyn’s Quay, Port Talbot docks. SEACAMS were requested to demonstrate the suitability of the water for these activities by documentation of discharges entering the water body, bacteriological sampling for indicators of sewage discharge, measurements of the physical properties of the water, specifically water temperature and a mapping survey of potentially hazardous structures below the surface of the water.
In collaboration with Cardigan Bay Marine Wildlife Society and the West Wales Charter Company. Developing protocols to analyse and write up the data from a specific set of surveys into a report, this project will enable the centre to attract more funding in the future and increase the knowledge available of cetaceans in welsh waters, both for conservation and the impacts of marine renewable devices on cetaceans.
The management of coastal environments demands comprehensive surveys. These are generally carried out by private consultancies which supply information for private and public sector bodies. SEACAMS works in collaboration with Aquatic Survey & Monitoring Ltd., assessing the possibilities of joining up different survey needs and improving value by incorporating additional parameters into existing surveys.
The location of the marshes, bordering the Teifi River within the high water tidal prism of the estuary, makes them vulnerable to changes in sea-level as a result of climate change. The Welsh Wildlife Centre is keen to understand how their management strategy may change as climate change begins to affect sea level. At a monitoring station at Milford Haven, sea-level is rising at 0.4 cm.a-1, and is expected to accelerate later in the century. In the future, saltwater incursions into the Teifi Marshes are likely to increase in extent, magnitude and frequency. The aim of the research is therefore to investigate how saltwater intrusions currently affect marsh ecology, with a view to predicting how the marsh communities may change in the future.
Solutions to the problems caused by anchor and mooring damage in seagrass in Wales are required. This requires engineering and design expertise that could form the development of a new product. To date, the design of existing environmentally friendly moorings has been reviewed (Egerton 2011) but this information needs to be built upon to provide solutions both in the long and short term. In the long-term a product is required that can be sold as an environmentally sound solution, however due to the time for development and the likely costs of such products, other short-term solutions are also required that can reduce the amount of impact before such products become available.
Titan Environmental Surveys Ltd specialise in gathering data relating to all aspects of the marine environment. The company approached SEACAMS to resolve technical difficulties concerning their HydroCamel water samplers. SEACAMS provided initial support through its in-house expertise in Engineering Analysis & Design, firstly dismantling and recording the design of the HydroCamel and secondly producing a 3D CAD Model for further technical analysis, finalising with a report about the HydroCamel technology with suggestions for design improvements. The initial SEACAMS assistance culminated with a Collaborative Research and Development project to optimise the design of the HydroCamel. This involved improvement of the electronic control unit and optical encoder connection, as well as reassembling and testing performance of the HydroCamel. Engineering drawings were provided for additional design improvement modifications.
Fisheries Biologist John Lancaster approached SEACAMS for assistance with the reverse engineering of a submersible sledge he had designed to undertake video surveys and photographs of the seabed. SEACAMS helped by reverse engineering the sledge to provide an accurate 3D CAD Model, which aided with the ongoing development and engineering. On completion, SEACAMS provided a complete set of production engineering drawings drafted to BS8888, these drawings have fully documented the sledge and provide the business with the option of mass production of the underwater sledge.
