Infaunal sedimentary communities underpin marine ecosystems worldwide. Understanding how disturbances such as oil spills influence infauna is therefore important, especially given that can be trapped in sediments for years or even decades. The 2010 Deepwater Horizon (DWH) event was the largest spill United States history, impacting habitats throughout Northern Gulf of Mexico. We investigated in...

Seagrass habitats exhibit high structural variability at local (<1 to 10s of m) and landscape (100 to 1000s of m) scales, which is closely linked with physical setting. In this study, we conducted 2 spring and 2 fall field surveys in 1991 and 1992 over a 25 km long portion of Core and Back Sounds, North Carolina, USA, to relate macrofaunal abundance to measures of seagrass landscape structure a...

1 Multi-season reflectance data from radiometrically and geometrically corrected 2 multispectral SPOT-5 images of 10-m resolution were combined with thorough field campaigns 3 and land cover digitizing using a binary classification tree algorithm to estimate the area of 4 marshes covered with common reeds (Phragmites australis) and submerged macrophytes 5 (Potamogeton pectinatus, P. pusillus, M...

The purpose of this study was to map the areal extent and density of submerged aquatic vegetation, principally the seagrasses, Zostera marina and Ruppia maritima, as part of ongoing monitoring for the Barnegat Bay, New Jersey National Estuary Program. We examine the utility of multiscale image segmentation/object-oriented image classification using the eCognition software to map seagrass across...

Within the past few decades, major losses of seagrass habitats in coastal waters impacted by cultural eutrophication have been documented worldwide. In confronting a pressing need to improve the management and protection of seagrass meadows, surprisingly little is known about the basic nutritional physiology of these critical habitat species, or the physiological mechanisms that control their r...
