    • Integrated Krill Model WG-SAM-14/20

    Metadata Updated: March 1, 2024

    The integrated modeling framework for Antarctic krill (Euphausia superba) has been extended to include estimates of krill growth consistent with survey data and to use multi-nation survey data collected from 1981 to 2014 near the Antarctic Peninsula. Four models of the population dynamics of Antarctic krill in Subarea 48.1 based on different aggregations of the data are described to illustrate the capabilities of the framework.

    Lineage Raw acoustic data are collected from calibrated echosounders and archived on the vessel and later on shore-based servers. Samples from nets are processed on board the vessel, and descriptive information is entered into data logs and/or databases. All datasets are ultimately returned to the SWFSC for QA/QC, archiving and review.
