Coastal Sediment Dynamics and River Discharge as Key Factors Influencing Coastal Ecosystem Productivity in Southeastern Lake Michigan
Coastal Sediment Dynamics River Discharge Coastal Ecosystem Productivity Southeastern Lake Michigan
2015/7/22
A central question addressed by the Episodic Events in the Great Lakes Experiment (EEGLE) was the extent to which the spring phytoplankton bloom in southern Lake Michigan is influenced by a recurrent ...
Differences in benthic metabolism, nutrient fluxes, and denitrification in Caulerpa taxifolia communities compared to uninvaded bare sediment and seagrass (Zostera capricorni) habitats
Differences in benthic metabolism nutrient fluxes denitrification in Caulerpa taxifolia communities uninvaded bare sediment and seagrass Zostera capricorni habitats
2014/4/4
Benthic metabolism, nutrient fluxes, and denitrification were measured in Caulerpa taxifolia communities that had recently invaded (between 2003 and 2008) bare sediments following the loss of Zostera ...
Variable sediment oxygen uptake in response to dynamic forcing
dynamic forcing Variable sediment oxygen
2014/4/16
Seiche-induced turbulence and the vertical distribution of dissolved oxygen above and within the sediment were
analyzed to evaluate the sediment oxygen uptake rate (JO2
), diffusive boundary layer t...
Nitrogen cycling in a deep ocean margin sediment (Sagami Bay, Japan)
a deep ocean margin sediment Nitrogen cycling
2014/4/18
On the basis of in situ NO{
3 microprofiles and chamber incubations complemented by laboratory-based
assessments of anammox and denitrification we evaluate the nitrogen turnover of an ocean margin s...
Sediment-mediated suppression of herbivory on coral reefs: Decreasing resilience to rising sea-levels and climate change?
Sediment-mediated suppression of herbivory coral reefs Decreasing resilience rising sea-levels climate change
2014/4/21
We describe a mechanistic basis for maintaining an alternative degraded stable state on coral reefs: sediment-laden algal turfs. Using remote underwater video cameras we quantified rates of herbivory ...
Response of the methanogenic microbial community of a profundal lake sediment (Lake Kinneret, Israel) to algal deposition
methanogenic microbial community a profundal lake sediment algal deposition
2014/4/21
An algal bloom of Peridinium gatunenese generally precedes the annual maximum of methane release from the profundal sediment of Lake Kinneret. Therefore, we investigated the response of the sediment m...
Characterization of methanogenic Archaea and stable isotope fractionation during methane production in the profundal sediment of an oligotrophic lake (Lake Stechlin, Germany)
methanogenic Archaea stable isotope fractionation during methane production profundal sediment an oligotrophic lake
2014/4/22
The methanogenic archaeal community, methane production, and carbon isotopic fractionation were studied in the profundal sediments of oligotrophic Lake Stechlin. Because the water column of oligotroph...
Top-down and bottom-up controls on sediment organic matter composition in an experimental seagrass ecosystem
Top-down bottom-up controls sediment organic matter composition an experimental seagrass ecosystem
2014/4/21
We tested the singular and interactive effects of resource availability (light) and community composition (food chain length and herbivore species richness) on eelgrass (Zostera marina) ecosystem prop...
Bleaching, energetics, and coral mortality risk: Effects of temperature, light, and sediment regime
Bleaching energetics coral mortality risk Effects of temperature light sediment regime
2014/4/23
The most severe outcome of coral bleaching is colony mortality. However, the risk of mortality is one of the least understood consequences for reef corals under climate-change scenarios. Specifically,...
Biodiversity and food web structure influence short-term accumulation of sediment organic matter in an experimental seagrass system
Biodiversity and food web structure influence short-term accumulation of sediment organic matter in an experimental seagrass system
2014/4/23
We tested the effects of grazer diversity and food chain length on the quantity and quality of accumulated sediment organic matter (SOM) in experimental eelgrass (Zostera marina) mesocosms. By use of ...

Biostabilization of cohesive sediment beds a freshwater wave-dominated environment
2014/4/23
An assessment of bed sediment stability was carried out over biostabilized and nonbiostabilized cohesive sediment within a laboratory wave flume. Biofilms of 5, 9, and 15 d were grown over kaolinite, ...
