“…Although earlier grab‐sample‐based spatial profiling undoubtedly advanced our understanding of drivers of spatial heterogeneity (e.g., Dent & Grimm, 1999; Sullivan & Drever, ; Likens & Buso, ), sensors greatly increase the frequency and ease at which measurements can be made, expanding both the resolution and the extents that can be profiled. Multiple recent studies have demonstrated the insights that can be gained from sensor‐based longitudinal profiling of properties including light (Gardner, Ensign, Houser, & Doyle, ), temperature (Ensign et al, ), nutrients (Hensley, Cohen, & Korhnak, ; Kunz, Hensley, Brase, Borchardt, & Rode, ), colour, and dissolved oxygen (DO; Hensley, Kirk, Spangler, Gooseff, & Cohen, ), from reach to regional scales (Gruberts, Paidere, Škute, & Druvietis, ; Kobayashi & Iwata, ; Loken et al, ).…”
