Our scientists have over 20 years of experience using SPI in support of sediment and benthic habitat evaluations for site and impact assessments, dredged material disposal site monitoring, remediation, wood debris and fish waste impact evaluations, and effluent discharge monitoring. As a rapid assessment tool, NewFields has found SPI to be particularly effective for identifying areas of the seafloor impacted by physical and chemical disturbances.
NewFields works closely with our clients to determine the study design and select the key SPI parameters that address the objectives of their study.

Sediment Profile Imaging Applications
SPI technology is used for a wide variety of applications to support investigations for U.S. and international customers:
- Mapping the distribution of dredged material at open water disposal sites in both fine-grained and sandy environments;
- Sand mining reconnaissance and impact monitoring;
- Baseline and monitoring of offshore exploratory drilling sites and cable or pipeline corridors on the seafloor;
- Impact assessment of oil and drilling mud releases from offshore oil-drilling platforms;
- Construction monitoring of sediment capping projects and Confined Aquatic Disposal (CAD) sites;
- Measurement of aquaculture impacts due to salmon and mussel farms;
- Effluent discharge monitoring (e.g., outfalls, wood pulp, and seafood waste); Mapping the distribution and impact of wood debris near log storage and wood industry sites;
- Refinement of sediment sampling designs through SPI reconnaissance;
- Mapping of erosional, non-depositional areas and/or low energy depositional sites; and
- Identification of areas with chronic organic overloading.
A few examples highlighting NewFields’ experience in these applications are provided below.
