Authors Summary
Report SC/69b/SHxx provides an update of the ICG on southern right whale acoustics. This ICG was established in 2020 to assess the offshore SRW distribution using passive acoustic monitoring in the Southern Ocean. During 2023, two virtual meetings were held, and progress was made towards the assembling of a training dataset for the development of automated detectors of SRW calls. At the last meeting, action points were identified to progress with the work in the coming months, including the finalisation of a training dataset, the development ofan automated detector and the processing of existing datasets from potential SRW feeding grounds to assess trends in the acoustic presence of SRWs.

Abstract
In 2020, the Scientific Committee formed an Intersessional Correspondence Group (ICG) to assess offshore southern right whale (SRW) distribution using passive acoustic monitoring in the Southern Ocean (Item 8.2.3.4, IWC, 2021). The main goal of this ICG is to assess what SRW call data exists offshore and at high latitudes (including data from both Australia?s Integrated Marine Observing System (IMOS) and the Southern Ocean hydrophone network (SOHN)) and consider an appropriate analysis framework for using these data to assess southern right whale offshore distribution. This work relates to the current ongoing assessment of SRWs on a global scale, as well as the related IWC-SORP Theme 6. This report serves to provide an update on the work conducted in 2023, which included two virtual meetings and progress towards assembling a training/test dataset for the development of automated detectors of SRW calls.
