Of the 16 EPA priority PAHs that were used in this study as possible tracers, 11 are high molecular weight (HMW) PAHs, meaning they are composed of four or more aromatic rings, and five are low molecular weight (LMW) PAHs, meaning they are composed of two or three rings. The ...
6). In other words, more than half of the variance explained by the RDA was attributed to the sediment physico-chemical parameters, meaning that much of the microbial community compositional differences observed in the sediment core samples were coincident with the physical and chemical differences ...
A threshold has been established based on SGI, meaning pixels with an SGI < 0.5 were considered devoid of sun glint interference. Land-Cloud-White-cap-Masking After the de-glinting process, masking was carried out to separate out clouds, lands, and whitecaps. For the present study, cloud ...
In the Netherlands, for example, the introduction of solutes is even prohibited or limited by law. Furthermore, the potential of natural tracers is often limited because drinking water extraction wells are located at sites where groundwater quality has to be as optimal as possible, meaning the ...
The amount of clay reached its maximum near the surface, meaning the silt gyttja classification came the closest to the clay gyttja in this interval, which correlated with its function to act as a parent material to soils [41]. Today, the remnants of the aeolian sand deposits can still ...
A disadvantage of the method is that spectral indices can provide only relative estimates of pigment abundance, and spectral features can be non-unique, meaning it is possible for absorption troughs to be caused by sedimentary components other than chloropigments. The combination of the high-...
