-Oceanographic Services
|
Aspect Land & Hydrographic Surveys provide multi-disciplinary oceanographic services and support to the marine construction, civil engineering, renewable energy, water and maritime industries. Our survey and consultancy services are based on knowledge, innovation and experience with stringent quality assurance via our ISO 9001:2008 accreditation. Both public and private sector industries are being increasingly required to monitor their associated works and its impact on the environment, ranging from seabed profiling and classification, current monitoring and sediment contamination to the effect of marine construction projects on tidal patterns, benthic testing, turbidity monitoring and measuring the discharge of pollutants into watercourses. -Our oceanographic survey services include; |
 |
|
| Current Monitoring - data capture, analysis and reporting of tidal flow characteristics at specific locations. Parameters recorded include speed, direction, temperature, salinity and water depth. Applications include establishing estuarine flow patterns, river gauging, a variety of coastal engineering, marine construction and outfall projects. |
 |
kkk | Grab Sampling - collection of seabed sedimentation and particle distribution analysis for investigation of specific seabed features, marine organisms i.e. meiobenthos, renewable energy projects and enviromental impact studies i.e. extent of contamination. |
 |
| Dispersion Studies - in conjunction with dye tracing, additional information on tidal movement and dispersion can be achieved through the use of longer term tracers such as spores. This combined methodology is often used to investigate longer term effects; determining whether a pollutant released from a particular location will reach a specific area, i.e. impact of discharge on beaches. |
 |
Dye Tracing - tracing tidal & river flows by use of a dye released and tracked for periods of up to twelve hours, although the length of the track will be dependent on the water clarity and dispersive properties. Applications include pollution studies, natural waterflow analysis (rivers, lochs, ocean currents etc) and pipeline mapping. |
 |
|
| Drogue Tracking - use of free floating drogues to investigate a regional flow regime. Drogues are released and followed for a full tidal cycle providing information on the typical flood and ebb excursions in a given area. Drogues can also be used to illustrate the distribution of the currents in a survey area at different stages of the tide. |
 |
ADCP Surveys - deployment to fix seabed mounting, recovery and analysis of tidal data recorded over a time period to investigate the variability of current trends and intensity for offshore works, marine pipelines, outfall deployment, renewable energy and coastal engineering projects. |
 |
|
| Meteorological Studies - installation of meteorological stations for data logging & statistical analysis, comparison of oceanographic data, correlation of water levels / depths and evaluation of dispersion studies using wind speed and directional data. End users include marine engineers & consultants, utility companies and dredging contractors. |
 |
Underwater Imagery - digital stills, diver led underwater videos or tripod mounted remote videos, with full narration, of seabeds, pipeline routes, outfall location / condition surveys, rivers, weirs and lochs for marine engineering, dredging contracts, environmental classification and renewable energy projects. |
 |
|
Our marine surveyors can implement appropriate monitoring and sampling programmes tailored to suit the needs of individual clients and projects. These can vary from coastline erosion studies to dispersion and dilution works for proposed and existing outfalls, current monitoring, seabed classification works, sediment sampling and particle distribution analysis. Data sets can also be obtained on water salinity, temperature & conductivity, current & wave patterns and tidal flow movements to complement both marine and environmental studies. All oceanographic data is archived on permanent storage devices and can be made available on client networks for further investigation or for use on future research and development projects. |
