Bacterial and archaeal phylotypes associated with distinct mineralogical layers of a white smoker spire from a deep-sea hydrothermal vent site (9°N, East Pacific Rise)
(2006)A diffusely venting chimney spire from the East Pacific Rise (9°N) was analysed by petrographic thin sectioning and 16S rRNA gene cloning and sequencing in parallel, to correlate microbial community composition with ... -
Gene expression profiling of microbial activities and interactions in sediments under haloclines of E. Mediterranean deep hypersaline anoxic basins
(2016)Deep-sea hypersaline anoxic basins (DHABs) in the Eastern Mediterranean Sea are considered some of the most polyextreme habitats on Earth. In comparison to microbial activities occurring within the haloclines and brines ... -
Hazardous toxic metal(loid)s in top- and deep-soils during the transformation of aquaculture ponds restored to farmland
(2022)The pollution risks due to the soil migration of toxic metal(loid)s (TMs) are a greatly hazard to ecological environment as well as animal and human health. Previous studies have primarily focused on surface contamination ... -
Herbal plants- and rice straw-derived biochars reduced metal mobilization in fishpond sediments and improved their potential as fertilizers
(2022)Fishpond sediments are rich in organic carbon and nutrients; thus, they can be used as potential fertilizers and soil conditioners. However, sediments can be contaminated with toxic elements (TEs), which have to be immobilized ... -
Low Bacterial Diversity and High Labile Organic Matter Concentrations in the Sediments of the Medee Deep-Sea Hypersaline Anoxic Basin
(2012)Studies in the center and margin of the Medee Basin, a Mediterranean deep-sea hypersaline anoxic basin, and at a reference site during Penelope cruise (2007), revealed the existence of a 7 m-thick halocline, with high ... -
Metazoans of redoxcline sediments in Mediterranean deep-sea hypersaline anoxic basins
(2015)Background: The deep-sea hypersaline anoxic basins (DHABs) of the Mediterranean (water depth ~3500m) are some of the most extreme oceanic habitats known. Brines of DHABs are nearly saturated with salt, leading many to ... -
Optimum design of the entrance of a fishpond laterally to the main stream of an open channel
(2017)In this study, the optimum design of the entrance of a fishpond laterally to the main flow of an open channel was investigated numerically and experimentally. The flow characteristic measurements were realized with the PIV ... -
Release of toxic elements in fishpond sediments under dynamic redox conditions: Assessing the potential environmental risk for a safe management of fisheries systems and degraded waterlogged sediments
(2020)Waterlogged soils and sediments contaminated with potentially toxic elements (PTEs) constitute a complicated case of degraded areas; their management requires understanding of the dynamic redox-driven PTE mobilization. ... -
Simulation modeling of runoff, groundwater flow and sediment transport into Kastoria Lake, Greece
(2003)Kastoria Lake is located in northwestern Greece. The whole basin of the lake is about 253 km(2). For the computation of the surface water volume inflowing into the lake from the main streams of the sub-basins located around ...
