Freshwater Stream Invertebrates: Response to Water Quality Impairment and Physical Habitat Alteration
Summary Results of three large-scale regional benthic macroinvertebrate monitoring programs from Los Angeles, Orange, and San Diego counties were analyzed. Benthic community quality was quantified using a southern California IBI and was compared to the physical habitat quality scores of each monitoring reach. The purpose of the comparison was to determine if physical habitat quality was a ...

Environmental monitoring of two fish waste ocean disposal sites in Newfoundland and Labrador, Canada
Sediment contaminant and benthic community surveys were conducted at two fish waste ocean disposal sites in Newfoundland and Labrador, Canada, to assess the environmental impacts of the disposal activities. Despite a dispersive ocean environment, fish wastes accumulated at both sites, initially disturbing the benthic community through organic enrichment and oxygen depletion, but causing no ...

Benthic microbial loop and meiofaunal response to oil-induced disturbance in coastal sediments: a review
This review of benthic microbial loop and meiofaunal response to oil-induced disturbance describes examples from field investigations on some of the major oil spills of the past 20 years. It focuses on the microbial and meiofaunal compartments that, being characterized by short generation time, life cycle, sensitivity to environmental disturbance, are expected to respond rapidly to environmental ...

Evaluation of benthic assessment methodology in Southern California Bays and San Francisco Bay
Untitled Document Benthic invertebrates are important components of aquatic food webs that are sensitive to changes in environmental condition, which makes them ideal candidates for monitoring. However, assessments of benthic community data are difficult because biological communities are complex. Dozens of species and hundreds of organisms are often found in a ...

Predicted mixture toxic pressure relates to observed fraction of benthic macrofauna species impacted by contaminant mixtures
Species sensitivity distributions (SSDs) quantify fractions of species potentially affected in contaminated environmental compartments using test species sensitivity data. The present study quantitatively describes associations between predicted and observed ecological impacts of contaminant mixtures, based on monitoring data of benthic macroinvertebrates. Local mixture toxic pressures ...

Mining Project Life Cycle for Environmental Data Management
EarthSoft has more than two decades of experience in developing technology solutions to manage environmental data throughout a project lifecycle from inception to closure and reuse. A mining project from greenfield exploration to land reclamation after closure can often span many decades and costs billions of dollars. Mining is a high-risk activity with potential of high returns. Mining also ...
