This repository contains Rmarkdown scripts to analyze the biomass density estimates from the ASAM-2021 metadata table.
The Metadata table is available here: https://groups.ccamlr.org/node/522.
At the moment there are two scripts, built to address priority work indentified during WG-ASAM-2021:
2.16 The Working Group agreed to summarise the acoustic survey biomass estimates from the updated table of metadata collated during WG-ASAM-2021 (also see paragraph 2.12) in an intersessional e-group, and undertook to provide advice on biomass and krill density estimates to WG-EMM-2021 at the subarea and any other appropriate spatial scales, with preliminary results on estimates of uncertainty provided to WG-SAM-2021 to assist with generalised R yield model (Grym) projections. A draft template developed by the Working Group for the summary of estimates is shown in Table 1.
-
The script asam2020Var.Rmd is focused on uncertainty estimates.
-
The script 02.ASAM_2021_KrillBiomassStatsVx.Rmd is focused on mean estimates. The filtered data is available here: https://groups.ccamlr.org/node/524
