In this poster I will present the results from text mining analyses of the abstracts of the current and previous ICES acoustic symposia as well as WGFAST working group reports. By creating and comparing lists of the most common words in each symposium and WGFAST reports it will be possible to measure the overall change in breadth and possible shifts in focus in the field of marine ecosystem acoustics. The same analysis will also identify the contribution of WGFAST to the progress in the field. An analysis of the authors will provide means to characterize the structure of the research fellow communities participating in ICES acoustic symposia and WGFAST meetings.
