“…Furthermore, our 2019 estimate of krill consumption by fin whales within the survey area represents about 12.7% of the 2019 summer krill standing stock estimated from data collected during the same survey 19 . This is consistent with recent estimates by Baines et al 40 that baleen whales may consume 19-29% of the krill standing stock around the South Sandwich Islands.…”

“…If these higher estimates had been used to calculate krill consumption by whales it is likely that this would have impacted the outcome of the risk assessment. Further, recent estimates of baleen whale feeding rates (Savoca et al, 2021), suggest estimates of krill consumption may be much greater than those estimated by Reilly et al (2004) and those used here, whilst Baines et al (2022) suggest that these higher feeding rates may predominantly occur at the start of the feeding period.…”

“…For example, our proposed fleet of USVs could also be equipped with scientific echosounders to obtain information on krill in the vicinity of vocalising whales. This information could then be used to better understand the relationship between ABWs and krill (abundance, distribution, and swarm characteristics), via investigations similar to that described in previous studies of ABWs (Miller et al, 2019b) and other Antarctic whale species (Santora et al, 2010;Nowacek et al, 2011;Herr et al, 2016;Baines et al, 2022).…”
