1.3 Indicator brief description
Model-based abundance and annual center of gravity indices for zooplankton groups sampled by NEFSC surveys
1.4 Indicator visualization
Abundance Large and small copepod groups are mainly fluctuating without trend in both spring and fall across the EPUs. However, a significant long term decrease in small copepods was apparent in the MAB during fall, and a recent decrease during spring. Similarly, zooplankton volume is fluctuating without long term trends over time. A recent significant decline was detected for Spring zooplankton volume in the MAB. Euphausiids, in contrast, show increasing trends over time in all regions during fall, and in the MAB during spring. In addition, a significant recent increase was detected in the GOM in Fall. Center of Gravity Small copepods in fall are trending northeast similar to forage fish and aggregated survey species. Small copepods in spring are trending north. Large copepods in fall are trending west, similar to benthos. No significant change for Calfin, Euphausiids, or Zooplankton volume center of gravity over time.

2.1.3 Are methods clearly documented to obtain source data and calculate indicators?
Yes
2.1.3.1 Can the indicator be calculated from current documentation?
VAST is a spatio-temporal modeling framework used for index standardization (James T. Thorson and Barnett 2017; James T. Thorson 2019). Zooplankton models were evaluated using two stages of model selection to determine whether to include spatial and spatio-temporal random effects, and “catchability” covariates affecting the observation process: day of year. Model selection script is https://github.com/NOAA-EDAB/zooplanktonindex/blob/main/VASTscripts/VASTunivariate_zoopindex_modselection.R Models were run using REML and without bias correction. Two different observation models were applied. The default VAST index standardization (purpose = “index2” in make_settings) uses a Gamma distribution for positive catches and an alternative “Poisson-link delta-model” using log-link for numbers-density and log-link for biomass per number (ObsModel= c(2,1)). We applied the default observation model to Calanus finmarchicus (calfin_100m3) and Large copepods (calfin_100m3 + mlucens_100m3 + calminor_100m3 + euc_100m3 + calspp_100m3) datasets. The default was used for index standardization of stomach contents data for pelagic and benthic forage indices. It is intended for continuous data, which includes biomass data and “numbers standardized to a fixed area” (see section starting at line 239 in the VAST user manual here. I am interpreting zooplankton abundance per 100 cubic meters as numbers standardized to a fixed area (volume) in applying the Gamma observation model. For data where there are some years where the species is present in all (or 0) samples, estimating the probability of encounter fails (or at least, VAST won’t let you try). In these cases, the options are to treat intercepts representing temporal variability as random effects (by setting RhoConfig Beta or Epsilon entries to something other than 0), or to use a different link function. We intend for our indices to potentially be used in assessment (though as a covariate rather than an index, so maybe I’m being too strict), so the recommendation is to “minimize covariance in the estimated index by excluding any temporal correlation on model components (i.e., the intercept is a fixed effect in each year, and the spatio-temporal term is independent in each year)” (James T. Thorson 2019). All of the small copepods datasets had at least one year where our small copepods groupings were encountered at all stations. None had years with 0 encounters. Therefore, we used a different link function, the Poisson-link fixing encounter probability=1 for any year where all samples encounter the species. We kept all other settings for index standardization the same, but set (ObsModel= c(2,4)). Model selection results are reported at this link: https://noaa-edab.github.io/zooplanktonindex/CopeModSelection.html In the second stage of model selection, the day of year covariate had mixed success. Results of the best models which both converged and had the lowest AIC are reported here: https://noaa-edab.github.io/zooplanktonindex/CopeModResults.html
2.1.4 Are indicator underlying source data linked or easy to find?
Source data are NOT publicly available.
2.1.4.1 Where are source data stored?
The Northeast Fisheries Science Center has conducted zooplankton surveys since the 1970s. The dataset through 2022 used in this analysis was obtained from the Oceanography Branch.
2.1.4.2 How/by whom are source data updated? Are future updates likely?

2.2 Indicator analysis/testing or history of use
2.2.1 What decision or advice processes are the indicators currently used in?
Zooplankton are primary consumers in marine ecosystems that transfer energy from phytoplankton to fish, marine mammals, and birds. The Northeast Fisheries Science Center has conducted zooplankton surveys since the 1970s. Spatially explicit indices of abundance for several zooplankton groups were estimated using spatio-temporal modeling (VAST, [10]; [11]). The zooplankton groups in the model include: Copepods Calanus finmarchicus, = Single species group, used to represent large copepods in the small-large index) Large copepods ALL: Calanus finmarchicus, Metridia lucens, Calanus minor, Eucalanus spp., Calanus spp. Small copepods ALL: Centropages typicus, Pseudocalanus spp., T_emora longicornis_, Centropages hamatus, Paracalanus parvus, Acartia spp., Clausocalanus arcuicornis, Acartia longiremis, Clausocalanus furcatus, Temora stylifera, Temora spp., Tortanus discaudatus, Paracalanus spp. Small copeopods SOE (used to represent small copepods in the small-large index): Centropages typicus, Pseudocalanus spp., Temora longicornis, Centropages hamatus Euphausiids (krill) modeled as family level group; not differentiated to species in data Zooplankton volume a metric of total zooplankton; all groups combined displacement volume in the collection net
2.2.2 What implications of the indicators are currently listed?
Fluctuations in zooplankton community composition can affect both the consumption of phytoplankton vs the export of energy to the benthos, as well as the availability of prey for zooplankton feeding forage fish, marine mammals, and seabirds. The relative dominance of large and small copepods in Northeast US ecosystems has been liked to changes in fish productivity [12,Morse2017?]. Distribution shifts for zooplankton may result in mismatches with zooplankton feeding fish, marine mammal, and seabirds.
2.2.4 Have the indicators been tested to ensure they respond proportionally to a change in the underlying process?
No
