Report from a krill focused survey with RV Kronprins Haakon and land-based predator work in Antarctica during 2018/2019
The primary objective for this krill research activity was twofold 1) to conduct a survey that provides updated estimates of the biomass and distribution of krill which are used in models to estimate sustainable yield in CCAMLR Area 48 and 2) to develop knowledge on the marine environment essential...
