| Client: | Project: | Location: |
| Harbour Authority | Environmental monitoring and ecological impact assessment of sensitive habitats and species in the Salcombe-Kingsbridge Estuary. This multi-disciplinary project included modelling the sediment plumes, contaminant analysis and pre and post dredge monitoring. Survey methods used included diving on the seagrass beds and sensitive habitats, ADCP, drogue tracking and turbidity monitoring. | Salcombe-Kingsbridge Estuary |
| Ports and Infrastructure Consultants | IHO special order multibeam bathymetric survey for QHM of the Naval dredge boxes in Devonport for routine monitoring pre dredging. | Devonport |
| District Council | Environmental monitoring and ecological impact assessment of sensitive habitats in support of their water injection dredging activities. Assessment of tidal flows and bathymetric surveys to determine accumulation and movement of dredge materials. | Ramsgate |
| Dredging contractor | Ecological monitoring of a dredging project. This included monitoring the extent and magnitude of the turbidity plume and monitoring its effects on protected species. Specifically this addressed the stalked jellyfish (UK BAP species) and required periodic assessments of the stalked jellyfish populations in littoral pools close to the dredging site and at a reference area. Sampling of sediment to depths of three meters for contamination assessment. | Penzance |
| Marine Services Consultancy | Multibeam bathymetric survey undertaken to determine whether any changes in the seabed topography had occurred following the establishment of a new marina in the area. | Bridgend |
| MoD | Intertidal and subtidal habitat assessment to establish a baseline from which the potential impacts from a proposed MoD landing craft co-location project were determined. The proposed development site was located adjacent to a SPA and within Plymouth Sound and Estuaries SAC, and also had the potential to affect a number of BAP priority habitats and species. | Tamar Estuary |
| Consultancy | As part of the assessment of a proposed coastal defence scheme, a hydrodynamic and water quality model was built to predict the effects of the construction of a submerged breakwater and nourishment of a beach area. The model was used to simulate the movement and dispersion of sediments both during and after construction, and also to predict the effects of uncontrolled pollutant releases following the proposed works. | Marsalform Bay, Malta |
| Harbour authority | Pre and post dredging surveys of the inner outer harbour and approach channels. Collection of Acoustic Doppler Current Profile (ACDP) data and modelling in support of dredging operations. | Ramsgate Harbour |

| Developer | Intertidal habitat mapping and ecological assessment to determine the potential impacts of a development proposal on sensitive and protected habitats and species. The potential impact of both the construction and operational phases upon the SAC, SPA and UK BAP Priority habitats/species was determined. Recommendations were made for mitigation. | Drake’s Island, Plymouth Sound |
