Validation of sink rates of longlines measured by two different methods
with bottles averaged 0.13 ± 0.02 m.s-1 compared to 0.21 ± 0.07 m.s-1 recorded by TDRs. This difference ... difficult and unreliable with bottles. Bottles had a higher failure rate (51 – 68 %) than TDRs (> 90 ... %), for example, with string becoming entangled or bottles vanishing from sight. We recommend while ...
