DESCRIPTION OF HABITAT/COMMUNITY FOR EXPERT ASSESSMENT
The water column (pelagic) community includes microbes, phytoplankton, zooplankton, fish and other higher trophic levels including seabirds, marine reptiles and marine mammals. By definition, the pelagic community is mobile, as smaller species are moved passively by currents, and larger species often move over large distances, both horizontally and vertically. Here we focus on the neritic zone, the area close to the coast and overlying the continental shelf. We analyse the abundance/biomass of a selected group of pelagic trophic levels, those that are monitored and readily available in the neritic pelagic region from IMOS (i.e., Chlorophyll a representing phytoplankton biomass, Zooplankton biomass and Fish larval abundance).

DATA STREAM(S) USED IN EXPERT ASSESSMENT
We analysed Chlorophyll a, Zooplankton biomass and Fish larval data from the IMOS National Reference Stations, see Eriksen et al. (2019) for detailed methodology for Zooplankton, Davies & Sommerville (2020) for Chlorophyll a and larval fish methodologies).

Statement: QUALITY OF DATA USED IN THE ASSESSMENT
IMOS data used in this assessment are the only time series information available in Australia suitable for this analysis. Before the introduction of IMOS, this assessment would not have been possible. Collecting and counting zooplankton data in IMOS adheres to strict quality control protocols (Eriksen et al. 2019). All data are collected under Ocean Best Practices, the BGC manual is published in Frontiers OBP repository (Davies & Sommerville 2020), https://repository.oceanbestpractices.org/handle/11329/1490.
