Modular shadowgraph imaging for zooplankton ecological studies in diverse field and mesocosm settings
Published:
Here, we demonstrate that versatile configurations of shadowgraph imaging, including modular benchtop, handheld, and towed, compact vehicle systems (along with customizable software), allow for tailoring sampling to a variety of marine and freshwater settings (including mesocosms). These systems encompass a suite of possible architectures, designed for adapting the imaging depth of field, acquisition rates, sensor configuration, and deployment method to fit a wide range of sampling protocols, with high vertical resolution (~ 5 cm) and adequate taxonomic capabilities for > 0.5 mm organisms.

Assessing the Temporal Variability and Drivers of Transparent Exopolymer Particle Concentrations and Production Rates in a Subtropical Estuary
Published:
Transparent exopolymer particles (TEP) create the backbone of marine snow aggregates and act as a central mechanism shuttling carbon from the surface to deep ocean. Here, TEP dynamics were evaluated across weekly, tidal, and diel time scales.
