To provide information on how interannual changes in the pelagic environment and larger scale changes in circulation influence zooplankton communities of the Scotian Shelf, in the Canadian northwest Atlantic, multivariate analyses were used to evaluate mesozooplankton species associations and large‐scale spatial patterns in zooplankton communities at both the Scotian Shelf scale and the larger Atlantic Canadian shelf scale. Depth and temperature associations were dominant factors structuring Atlantic Canadian shelf communities. Scotian Shelf species groups could be categorized as dominant shelf species, warm shelf species, Arctic Calanus species, and warm and cold offshore species. The abundance of immigrant groups, Arctic Calanus and warm offshore species, were strongly correlated with variability in temperature, ...
