Imaging systems have been proven useful for marine ecology. However, deploying them in shallow coastal waters are often hampered by complex dynamic processes which often lead to sub-ideal image quality, highly variable contents and backgrounds. In the present study, we deployed a shadowgraph imaging system (PlanktonScope) to understand the spatial and temporal dynamics of dominant plankton taxa and an adaptive resolution imaging sonar (ARIS) to quantify forage species and their habitat utilization in shallow water estuaries. Results from PlanktonsCope captured a full bloom cycle of Noctiluca sp. in Shenzhen Bay in 2016, while the deployment of ARIS system in Chesapeake Bay in 2016 – 2017 yielded useful estimates of forage abundance and their habitat utilization. Our results highlight that imaging systems could be useful for ecological monitor and forecasts in coastal waters and provide better insights on the spatial and temporal dynamics of key species, trophic interactions and habitat utilization.
