Risks Posed to the Antarctic Marine Environment by Acoustic Isntruments, a Structured Analysis
Maintenance and Update Frequency: unknown Statement: Unknown The risks posed by a range of acoustic scientific instruments were assessed by the construction of matrices of scale and likelihood. We recognized six levels of impact ranging from none or short term, minimal behavioural response (Level 1)...
