New hexactinellid sponges were collected from 2589 m depth on the Carlsberg Ridge in the Indian Ocean during deep-sea dredging. All fragments belong to a new genus and species, Indiellagen. n.ridgenensissp. n., a representative of the family Aulocalycidae described here. The peculiar features of this sponge, not described earlier for other Aulocalycidae, are: longitudinal strands present in sev...

Dredging for wild mussels Mytilus edulis Linnaeus, 1758 takes place in the marine protected areas (Natura 2000 sites) Denmark. The fishery is strictly regulated to limit impact of dredging benthic environment, and requires use modified lightweight mussel dredges. Nevertheless, depletion macrofauna associated with M. beds after from such dredges yet be quantified. Here, shown result a significan...

In August 1993, the Louisiana Department of Health and Hospitals (LDHH) investigated reports of acute respiratory illness among residents of two nursing homes and workers on a dredging barge in southern Louisiana; influenza type A has been confirmed as the cause of these outbreaks. This report summarizes the investigations of the outbreaks.

PURPOSE: This technical note describes the application of the Hydrologie Evaluation of Leachate Production and Quality (HELPQ) computer program, which facilitates the design of confined disposal facilities (CDFs) for contaminated dredged material by estimating leachate production rates and leachate quality. HELPQ is part of the Automated Dredging and Disposal Alternatives Modeling System (ADDAMS).

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract Trends and variations of the extreme water levels defined as exceeding/falling below certain thresholds (mean ± std) across the Pearl River Delta (PRD) are systematically explored using the linear regression method. Research results indica...

One of the potential environmental issues associated with dredging in the marine environment is the increase of suspended sediment concentrations (SSC) by generation and dispersion of sediment plumes. This can be mitigated by source control or by the installation of containment barriers like silt screens. This article focusses on hanging silt screens and describes: 1. The decision process for d...

Dredging activity may cause sediment resuspension, altering water quality regarding to dissolved oxygen and conductivity (measured in the field), turbidity, total suspended solids nutrients (such as phosphorus organic carbon), analyzed laboratory. In this work ten sampling campaigns were performed four areas of Santos harbor’s navigation channel, with different grain sizes, order monitor along ...
