The vibracoring option. The sample requirements can dictate whether vibracoring or another sampling technology should be used. Considerations include the depth of sediment to be sampled, the volume of sample needed, the requirement for an intact profile, the need to penetrate consolidated materials, and the likelihood of rodding effects. Survey planning. The vibracoring survey plans should take into account the survey objectives, the nature of the samples required, where to collect samples, how to handle cores and sub-samples, and the necessary procedures to follow. Site reconnaissance. An on-site reconnaissance prior to sampling can save considerable time and effort in the vibracoring survey. Scheduling the work. The work schedule can depend on a number of site-specific factors, including land and water access, logistics, and weather. Coring site positioning. Locating and documenting coring sites is easier with GPS, but field positioning with small boats can still be a challenge. Core handling. Field procedures for handling and transporting cores require some forethought. Vibracore processing. Processing vibracore samples may entail a separate operation ashore with appropriate tools and methods. Contamination control. Collecting and processing contaminated vibracores requires special measures to protect personnel and the site. Vibracore documentation. Appropriate field logs are essential to document site and sample conditions and characteristics. Health and safety plan (HASP). The site-specific HASP provides a blueprint for safeguarding personnel on the project site. Standard operation procedure (SOP). A vibracoring SOP outlines procedures for general use of sampling equipment in the field. |
