A TSA of the field tests in Baltimore Harbor was scheduled for August 15-16, 2011. The
breakage of the mooring structure on August 14, 2011 resulted in a 4-day suspension of the field
tests. The ACT QA Manager observed the recovery and inspection of the test instruments and
repair of cables prior to redeployment on August 18, 2011. The mooring and instruments were
restored to their initial condition, with the exception of the redeployment of the UViLux due to
the absence of a replacement cable.
Data Quality Audit
The objective of the DQA is to determine if the test data were collected according to the
requirements of the Test Protocols and associated SOPs. At least 10% of the data acquired during
the verification test was required to be audited for completeness, accuracy and traceability. The
ACT QA Manager traced data from the laboratory tests at Moss Landing Marine Labs and the
Nova Scotia field tests from the initial acquisition, through reduction and statistical analysis, to
final reporting to ensure the integrity of the reported results. Any calculations performed on the
data undergoing the audit were checked. The DQA confirmed that no systematic errors were
introduced during data handling and processing.
