Anthropogenic disturbances such as oil spills can cause mortality in benthic infaunal communities, reducing diversity and abundance impeding sediment ecosystem functions. Sublethal effects of exposure have received less attention, however. We conducted a mesocosm experiment exposing 2 taxa, the polychaete Owenia fusiformis brittle star Hemipholis elongata , to sublethal concentrations water-accommodated fraction (WAF) oil. evaluated WAF on animal behavior, bioturbation, oxygen demand (SOD)...
Abstract In shallow coastal systems, sediments are exposed to dramatic and complex variability in environmental conditions that influences sediment processes on short timescales. Sediment oxygen demand (SOD), or consumption of by sediment‐dwelling organisms chemical reactions within sediments, is one such process an important metric aquatic ecosystem functioning health. The most common instruments used measure SOD situ batch‐style benthic chambers, which generally require long measurement...
The benthic impact of aquaculture waste depends on the area and extent accumulation sediment surface below around farm. In this study we investigated effect flow biodeposit transport initial deposition by calculating a rough “footprint” an oyster farm in Damariscotta River, ME. We also compared site under to downstream “away” calculated be within footprint found similar biogeochemical fluxes, geochemical properties macrofaunal communities at away site, as well low organic enrichment both...
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 infaunal community structure at two shallow sites Chandeleur Islands, LA, States, over a 2-year...
Abstract This field study examined how sediment macroinfauna change patterns of oxygen demand (SOD) throughout a diel cycle. Sediments with greater faunal presence would be expected to have overall SOD, and at night may alter their behavior influence SOD depending on response low-oxygen stress. Dynamic bioturbation or bioirrigation also result in corresponding variation values short time scales. In situ flow-through benthic metabolism chambers were used measure high temporal resolution...

Changes in dissolved oxygen concentration can cause dramatic shifts chemical, biological, and ecological processes aquatic systems. In shallow coastal areas, this happen on short timescales, with increasing during the day due to photosynthesis declining at night respiration. We present a system controlled by an Arduino microprocessor that leverages oxygen-consuming capacity of sediments manipulate aquarium tank planned concentrations. With minor adjustments code, produce variety patterns,...
<title>Abstract</title> Shallow marine soft sediments serve an important function by remineralizing organic matter, which consumes dissolved oxygen in the process. Sediment demand (SOD) depends on overlying water concentration but can also be altered mixing and irrigating activities of sediment macroinfauna. Oxygen patterns shallow coastal waters vary substantially short time scales, frequently following a diel cycle. However, little is known about whether how presence macrofauna may affect...
Infaunal organisms are susceptible to disturbances such as hypoxia and sediment contamination; changes in infaunal community structure therefore often used indicators of anthropogenic disturbance. Susceptibility disturbance varies across taxa, either due physiological factors or behaviors functional roles that increase exposure. Both sources variability likely be heritable shared among related taxa. Thus, we would expect oil disproportionately affect taxa decrease phylogenetic diversity...
Animals with long, skinny bodies are often called “worms,” but there many kinds of worms—even in the ocean. Annelids (segmented worms) include garden earthworms, their ocean relatives come colors, shapes, and sizes. Some so small that they live between grains sand, while others can be longer than a human eat fish! Marine worms essential to food web, as both predators prey. They help create homes for plants animals by burrowing building tubes sediments. Scientists still discovering new worm...
