Phenological shifts in out-migrating juvenile Pacific salmon

This dataset contains the rates of change in juvenile migration timing of
66 Pacific salmon populations ranging from Oregon to Alaska, the rates of
change in timing of the initiation of spring phytoplankton bloom in nearby
coastal regions, and covariates. Species represented in this dataset
include coho salmon (Oncorhynchus kisutch), sockeye salmon (O. nerka),
Chinook salmon (O. tshawytscha), pink salmon (O. gorbuscha), chum salmon
(O. keta), and steelhead trout (O. mykiss). Rates of change in salmon
phenology includes rate of change in peak date, and rate of change in
range (number of days between 25th and 75th quantile of migration).
