Port and Harbour Authorities Routinely Survey
Port and Harbour authorities routinely survey their marine areas of responsibility to maintain desired water depths, and engage dredging contractors when needed.
Pre & post dredge surveys, Canals and waterways, coastal regions, congested harbours and approach channels
Prior to any dredging works taking place it is usual to retrieve grab samples or sediment cores of the material to be dredged and to have this analysed to determine the physical and chemical properties of the dredge material.
Dredging - It is often necessary to carry out sub-bottom profiling surveys and geotechnical investigations to quantify the depth that an area can be dredged to without resorting to rock blasting.
Marine Geophysics is used for projects located at or near to:
Minerex Geophysics offers surveys for marine and river projects including:
The choice of geophysical method is the key to success in a challenging survey setting - we use seismic refraction and reflection, Schulte Waves, resistivity or magnetics to clarify the geology below the water bottom.
Water depth, tides and saline or fresh water presence are given conditions that are factored into the surveys.
Our speciality is the survey from land through the transition zone into the water with continuous geophysical data acquisition to create ground models either side of the coastline or river bank.
