Submerged aquatic vegetation can dramatically alter the drag, turbulence and diffusivity characteristics of flow in aquatic systems. As a result, the diffusion and advection of contaminants and particulates are greatly influenced. However, modeling efforts generally treat submerged vegetation merely as a source of drag. This study explores the idea that(More)
VIDEO ABSTRACT At Mistaken Point, Newfoundland, Canada, rangeomorph "fronds" dominate the earliest (579-565 million years ago) fossil communities of large (0.1 to 2 m height) multicellular benthic eukaryotes. They lived in low-flow environments, fueled by uptake [1-3] of dissolved reactants (osmotrophy). However, prokaryotes are effective osmotrophs, and(More)
The MIT Faculty has made this article openly available. Please share how this access benefits you. Your story matters. Abstract Aquatic flow over a submerged vegetation canopy is a ubiquitous example of flow adjacent to a permeable medium. Aquatic canopy flows, however, have two important distinguishing features. Firstly, submerged vegetation typically(More)
White DJ (2015) Challenges in transferring knowledge between scales in coastal sediment dynamics. " Packaging " coastal sediment transport into discrete temporal and spatial scale bands is necessary for measurement programs, modeling, and design. However, determining how to best measure and parameterize information, to transfer between scales, is not(More)

Predicting the transport of scalar species in aquatic canopies is important for understanding the physical and biological processes occuring in many aquatic environments. However, the flow and transport in canopies is quite complex and governed by a wide range of processes. This study attempts to identify the important mechanisms contributing to(More)
