Technology
Evaluations

ACT conducts two levels of Technology Evaluations: Verifications and Demonstrations. Technology Verifications focus on classes of commercially available instruments to provide confirmation that each technology meets the manufacturer's performance specifications or claims and/or provides verified data on those operational parameters that stakeholders require to make a use decision. Verifications are a 25-step process, which includes community consensus on test protocols, laboratory and field-testing, and QA/QC based on EPA and ISO guidelines. Field tests are carried out at no fewer than four but typically all six ACT partner sites. Technology Demonstrations involve fewer steps and focus on highlighting the capabilities and potential of pre-commercial or emerging early-stage technologies, building user awareness, and facilitating technology maturation and transition into operational observing. Working closely with developers, Demonstration field tests may be conducted at only two or three Partner sites, depending on stakeholder priority needs.

ACT Technology Evaluations also are open and transparent, free of charge for all applicants with appropriate instrumentation, and all results are released to the public in final reports. However, ACT and its Partner Institutions do not certify or guarantee performance of technologies, nor does ACT rank or directly compare the individual instruments tested.

Instrument performance demonstrations and verifications are necessary so that effective existing technologies can be recognized, and promising new technologies can become available to support coastal science, resource management, and ocean observing systems. To this end, ACT serves as an unbiased, third party testbed for evaluating sensors and platforms for use in coastal and ocean environments.
