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 کاملThe decadal mean ocean circulation and Sverdrup balance
Elementary Sverdrup balance is tested in the context of the time-average of a 16-year duration time-varying ocean circulation estimate employing the great majority of globalscale data available between 1992 and 2007. The time-average circulation exhibits all of the conventional major features as depicted both through its absolute surface topography and vertically integrated transport stream fun...
متن کاملDynamic Weighing
In fabricating flowmeters, the meter's calibration is its final and accuracy determining step that comprises a great time consumption relative to its completion from its single component parts. Thus calibration (unless the respective time of calibration for a flow meter is not minimized) may represent a relevant contribution to fabrication costs. High-accuracy liquid flow calibration facilities...
