Specialized Sampling in Coastal Waters (180)
Problem: Need to obtain uncontaminated samples in dynamic coastal waters to ensure reliable data to support decisions
Project Activity Scope (from Technical Overview Chart): Interaction Mechanisms through Measurement and Analysis System Applications
PNNL Solution: Provide specialized field sampling
- Ultra-clean sampling techniques
- Sediment, water, and biota samplers
- Remote and manual sampling methods (including SCUBA divers)
- Remotely operated sensor units including bio-optical buoy
- Research vessel for deployment
Capability summary: Staff at PNNL's Marine Science Laboratory have over 30 years experience in field studies and is at the forefront of sampling technology and methods in aquatic and terrestrial ecosystems. Field teams can be quickly mobilized for crisis situations such as hazardous spills, for sampling operations lasting a few days, or for survey assessments and monitoring programs lasting several years. PNNL field crews have successfully sampled hard-packed substrates to -46 ft. MLLW, as well as the delicate surface microlayer, and take measures to ensure that environmental samples are not contaminated by field equipment, processing and handling, or storage containers, particularly where ultra-trace levels of contaminants are measured.
