Progress Code: completed
Statement: Data quality are good. Sonobuoys that failed or had data quality issues are noted in the column 'Failure'. Issues with data quality for these sonobouys are described in the notes where appropriate.

Notes

Purpose
This data product was produced to provide a synoptic overview of cetacean species (top predators) that were acoustically detected during the 2021 TEMPO voyage. It is intended to complement other work done on the TEMPO voyage to understand the distribution of top predators in the vicinity of krill.

Data time period: 2021-01-29 to 2021-03-24
