Oceanographic Survey
Laboratory Analysis
To complement data acquisition, we run a fully equipped, independent accredited sediment testing and analysis laboratory.
Our experienced laboratory technicians provide a comprehensive range of data analysis, processing and reporting services.
We participate in the NMBAQC Scheme for Particle Size Analysis (PSA) and comply with BS EN872 for determination of Total Suspended Solids (TSS) for water sampling programmes.
We conduct PSA to determine the overall size and distribution of material within singular or multiple sediment samples, using a combination of laser analysis and dry sieving methods depending on material type. PSA data can subsequently be used for a wide range of applications from numerical model calibration to habitat classification.
We analyse samples for Total Organic Carbon (TOC) using a combination of drying ovens and high temperature furnaces. TOC provides an indication of the level of biological material and hence the suitability or quality of habitat.
With collected water samples, we analyse for TSS using fine grade filtration techniques. Analysed samples can be compared against oceanographic water quality datasets to aid numerical model calibrations.
Using our approved partners, we also provide detailed chemical analysis (trace metals, PCBs, PAHs) of collected sediment samples. Such information is often required when preparing marine licence applications.
