No PDF available ABSTRACT The sea floor is inhabited by diverse communities of animals that mix sediments through bioturbation and modify the physical properties of sediments. Infaunal activities, such as burrowing, construction of burrows and tubes, and ingestion and compaction of sediments into fecal pellets, can compact and dilate sediments and...
No PDF available ABSTRACT Muddy sediments are inhabited by diverse communities of animals that burrow, construct and irrigate tubes, ingest and egest sediments, and produce hard structures such as shells and exoskeletons. These infaunal animals mix sediments through bioturbation and modify the physical properties of sediments. Bulk density can be i...
Shallow coastal muddy sediments are important for global nutrient cycling and carbon storage and provide a habitat for diverse communities of organisms. Bottom shear stress from physical disturbances such as storms and hurricanes resuspend coastal muds, disrupting their cohesive structure. How biological vs. physical processes affect reconsolidatio...
Infaunal sedimentary communities underpin marine ecosystems worldwide. Understanding how disturbances such as oil spills influence infauna is therefore important, especially given that oil can be trapped in sediments for years or even decades. The 2010 Deepwater Horizon (DWH) event was the largest marine oil spill in United States history, impactin...
No PDF available ABSTRACT Depth-dependent variability in seabed acoustic and geophysical properties can be introduced by both physical and biogenic processes. An experiment was conducted near the mouth of Mobile Bay, Alabama to investigate spatial variability over a mud-sand gradient, where sediment properties showed lateral changes on the scales o...
No PDF available ABSTRACT Interstitial organic matter (OM) is a ubiquitous constituent of marine sediment, particularly prevalent in sediments with significant silt/clay fractions, and is often quantified across a wide range of disciplines. OM suspends silt and clay particles in the sediment matrix, adsorbs onto mineral surfaces, and resides primar...
No PDF available ABSTRACT Seabed variability introduced by physical or biogenic processes contributes to multi-scale horizontal and vertical variability in seabed acoustic and geotechnical properties. An experiment was conducted near the mouth of Mobile Bay to investigate such spatial variability over a mud-sand gradient. A normal-incidence bottom...
No PDF available ABSTRACT Storm disturbance of shallow coastal sediments can resuspend subtidal sediment and transport and deposit sand from beach erosion, creating sorted layers of differing grain sizes. These sediments provide habitat for diverse and abundant infaunal organisms that mix these layers (bioturbation), but how the reestablishment of...
No PDF available ABSTRACT Whether deposited from the water column or generated by benthic infauna, interstitial organic matter is a ubiquitous constituent of marine sediment and is particularly prevalent in sediments with significant silt/clay fractions. Interstitial organic matter suspends silt and clay particles in the sediment matrix, adsorbs on...
No PDF available ABSTRACT Nearshore and estuarine sediments experience varying sediment inputs that create sharp gradients in sediment properties over fairly small vertical and horizontal distances. In this study, we explored the sand-mud transition in sediment cores collected from Mobile Bay, AL, with acoustic and geotechnical approaches. A custom...
The benthic impact of aquaculture waste depends on the area and extent of waste accumulation on the sediment surface below and around the farm. In this study we investigated the effect of flow on biodeposit transport and initial deposition by calculating a rough aquaculture “footprint” around an oyster aquaculture farm in the Damariscotta River, ME...
Whether deposited from the water column or generated by benthic infauna, interstitial organic matter is a ubiquitous constituent of marine sediment and is particularly prevalent in sediments with significant silt/ clay fractions. Interstitial organic matter suspends silt and clay particles in the sediment matrix, adsorbs onto mineral surfaces, and...
Anthropogenic disturbances such as oil spills can cause mortality in benthic infaunal communities, reducing diversity and abundance and impeding sediment ecosystem functions. Sublethal effects of oil exposure have received less attention, however. We conducted a mesocosm experiment exposing 2 infaunal taxa, the polychaete Owenia fusiformis and the...
Benthic macrofauna play important roles in coastal ecosystems through their impact on nutrient cycling and by serving as an mportant trophic link. This study investigated the influence of environmental stressors on macrofaunal community abundance, biomass and diversity and evaluated impacts of those benthic organisms on nutrient fluxes and denitrif...
Polychaetes exhibit diverse feeding strategies and diets, with some species possessing hardened teeth or jaws of varying complexity. Species in the order Eunicida have complex, rigid, articulated jaws consisting of multiple pairs of maxillae and a pair of mandibles. While all Eunicida possess this general jaw structure, several characteristics of t...
I am looking for a vane shear instrument for testing marine sediment shear strength that can be submerged in salt water. Can anyone recommend a particular brand or instrument that works well underwater?
The title is Morphological examinations on the jaw apparatuses of some recent and fossil Eunicida (Polychaeta) (German title: Morphologische Untersuchungen an den Kieferapparaten einiger rezenter und fossiler Eunicoidea (Polychaeta).), published in Seckenbergiana maritima. I have only come across the original.
We are attempting to make luminophores with which we want to look at bioturbation. Does anyone know of any fluorescent/UV paint that is waterproof, nontoxic, and relatively inexpensive? Thanks!
