Northern East AtlanticNone1,924 (CODA Survey), 316 (SCANS Survey)* Project Report: Review of Trend Analyses in the AS [more] The population size estimate is based on data collected during SCANS-II (2005) and CODA (2007) surveys. See the previous Trend Analysis document for more details. SCAN-II and CODA reports can be found in the additional notes section. *Note: the estimated population size is for the whole survey area and not just for the Northern East Atlantic. The separate estimate for this region is not available. Separate estimates for Cuvier's beaked whales by themselves were also not available from the SCANS, CODA or Trend analyses reports, so the data has been taken from a report on beaked whale that also uses the SCANS-II information.

The notes in the Threat section (Related Content) refer to the level of importance needed to address causes of mortality (identified from post-mortem examinations) of cetaceans in the ASCOBANS Agreement Area. This information also comes from this report: Project Report: Review of Trend Analyses in the ASCOBANS Area (AC18_6-05_ProjectReportTrendAnalysis_Corr.pdf).
