Bathymetric depths of Lakes Geneva and Superior stations and the sampling events when zooplankton and larval tows were not collected. Standard zooplankton tows were 25 m to the surface, or from 1.5 to 2.5 m above the lakebed to the surface at shallow sites (0, B1, M3). A 64-μm closeable zooplankton net with a 0.5-m diameter mouth was used during sampling event 1 of Lake Geneva. During event 2, we collected samples with both the closeable net and the standard Lake Geneva double Bongo net with 64-μm and 200-μm mesh nets and 0.35-m diameter mouths. The Bongo net was used on all subsequent sampling events of Lake Geneva (3–6) and all eight Lake Superior sampling events. Dates and times of sampling events are provided in Table 1, and stations are shown in Figure 1. Unless otherwise noted all samples were collected at all sampling events.
