Linking Geology and Microbiology: Inactive Pockmarks Affect Sediment Microbial Community Structure
Pockmarks are geological features that are found on the bottom of lakes and oceans all over the globe. Some are active, seeping oil or methane, while others are inactive. Active pockmarks are well studied since they harbor specialized microbial communities that proliferate on the seeping compounds. Such communities are not found in inactive pockmarks. Interestingly, inactive pockmarks are known...
متن کاملOverview of Geology , Hydrology , Geomorphology , and Sediment Budget of the Deschutes River Basin , Oregon Jim
Within the Deschutes River basin of central Oregon, the geology, hydrology, and physiography influence geomoqhic and ecologic processes at a variety of temporal and spatial scales. Hydrologic and physiographic characteristics of the basin are related to underlying geologic materials. In the southwestern part of the basin, Quaternary volcanism and tectonism has created basin fills and covered an...
متن کاملGEOLOGY OF THE DRIFTPILE STRATIFORM , SEDIMENT - HOSTED Ba . - Zn - Pb DEPOSIT , NORTHERN BRITISH COLUMBIA
One of the world's largest concentrations of sediment-hosted stratiform zinc-lead-barite deposits is (Figure 1). The largest and most developed of these is located in the Gataga area of northern British Columbia the CirqueiSouth Cirque deposit, with estimated geological reserves of 38.5 million tonnes averaging 8.0% Zn, 2.2% Pb and 47.2 gitonne Ag at Cirque and gitonne Ag at South Cirque (M...
متن کاملSelecting Color-based Tracers and Classifying Sediment Sources in the Assessment of Sediment Dynamics Using Sediment Source Fingerprinting.
The use of sediment color as a fingerprint property to determine sediment sources is an emerging technique that can provide a rapid and inexpensive means of investigating sediment sources. The present study aims to test the feasibility of color fingerprint properties to apportion sediment sources within the South Tobacco Creek Watershed (74 km) in Manitoba, Canada. Suspended sediment from 2009 ...
متن کاملSediment fingerprinting in fluvial systems: review of tracers, sediment sources and mixing models
Suspended sediments in fluvial systems originate from a myriad of diffuse and point sources, with the relative contribution from each source varying over time and space. The process of sediment fingerprinting focuses on developing methods that enable discrete sediment sources to be identified from a composite sample of suspended material. This review identifies existing methodological steps for...
