Abstract Despite its widespread use, the ecological effects of shoreline armoring are poorly synthesized and difficult to generalize across soft sediment environments structure types. We developed a conceptual model that scales predicted shore-parallel based on two axes: engineering purpose (reduce/slow velocities or prevent/stop flow waves currents) hydrodynamic energy (e.g., tides, currents, waves) environments. greater impacts for structures intended stop as opposed slow water with...
Abstract Oceanographic and evolutionary inferences based on fossil assemblages can be obscured by age offsets among co‐occurring shells (i.e., time averaging). To identify the contributions of sedimentation, mixing, durability, production to within‐ between‐species offsets, we analyze downcore changes in age‐frequency distributions two bivalves California shelf. Within‐species are ~50–2,000 years for Parvilucina ~2,000–4,000 Nuculana 1,000–4,000 within 10‐ 25‐cm‐thick stratigraphic units....
Five thousand–year history of Native American oyster harvesting practices provides insight into modern reef restoration.
Benthic maps provide the spatial framework for many science and management activities in coastal areas such as identification protection of fish distributions associated habitat well monitoring changes benthos communities. To meet this need at Gray's Reef National Marine Sanctuary off Georgia, U.S.A., coast, we created fine-scale benthic by visual interpretation sonar imagery within a geographic information system. The major bottom types sanctuary—flat sand, rippled hard that is sparsely...
Abstract. Slump blocks are widely distributed features along marsh shorelines that can disturb edge habitats and affect geomorphology sediment dynamics. However, little is known about their spatial distribution patterns or longevity movement. We employed an unoccupied aerial vehicle (UAV) to track slump in 11 monthly images (March 2020–March 2021) of Dean Creek, a tidal creek surrounded by salt located on Sapelo Island (GA, USA). were observed both convex concave banks the all images, with...
ABSTRACT Extensive muddy tidal flats along the western coast of Korea are distinctly different from other intertidal environments used as standard models for sedimentation (e.g., North Sea). The Korean lack extensive, dendritic drainage systems, seaward barriers, landward salt marshes, and most sedimentary structures considered diagnostic (i.e., flaser, wavy, ripple-laminated bedding). Fifty-one cores were collected subtidal areas Nam Yang Bay to investigate distribution texture,...
Abstract Archaeological sites in beach and estuarine environments are continually threatened by diverse natural marine processes. Shoreline erosion, bluff retreat, sea level rise all present potential for site destruction. Using historic maps, aerial imagery, field survey methods a GIS, 21 potentially significant archaeological on Georgia barrier islands were selected determination of site‐specific rates shoreline change using powerful, new, moving‐boundary GIS analysis tool. A prioritized...
