Particle Size


Marine Solutions utilises a well-equipped on-site workshop and Wet Lab for a multitude of services, such as sediment particle size analysis, sediment settling time analysis, samples preservation, chemical handling and controlled conditions samples storage.

We maintain excellent working relationships with numerous laboratories around the state and on the mainland, including Analytical Services Tasmania, ALS Global, Infauna Data and Selfs Point Laboratory, through which we have access to an extensive range of routine and specialty environmental testing and analyses. Testing through a NATA-accredited facility is ensured for most routine analyses; should you require NATA accreditation for a non-routine request we are well-placed to advise on the most suitable facility for testing.

Sediment Sampling

Marine Solutions has conducted numerous projects requiring sediment sampling for a range of parameters. We are familiar with the process and procedures for sampling and assessment of sediments, and the manner for them to be safely sampled and handled as appropriate for the relevant analysis, whether that be contaminant, elutriate, pore-water, TOC, particle size, or other tests as required. We have the capabilities and equipment to collect sediment samples in the manner that best suits the requirements of a given project, be it by quad corer, vibrocorer, grab sampler, hand-collected by divers, or otherwise.

Selected Past Projects:

  • Sediment sampling and characterization of the Granton banks prior to the Tas Irrigation pipeline being laid.
