Geochemically, the sediments are classified as litharenites, shale, and wacke. The ICV (Index of Compositional Variability) values (0.92 to 1.10) indicate that the sediments have low compositional and mineralogical maturity. Major and trace element abundances display marked depletion of Na2O, CaO,...
Both columns and detectors are maintained at 30 °C. The ion chromatography system was run as described previously [20] with the following modifications. Anions were resolved by a 2 mm Dionex IonPac AS19 analytical column protected by a 2 mm Dionex IonPac AG19 guard column (Thermo...
The results of the NGHP and UBGH expeditions both indicate the existence of formations with high m values, which need to be classified separately. There are two reasons for this distinction: the characteristics of the reservoir or the abnormal increase in the salinity of the formation water in...
the laboratory. The mechanical properties of the hydrate-bearing sediments were classified with previous obtained results from 53 pressure cores and 223 synthetic cores, and empirical equations for triaxial compressive strength and deformation modulus were proposed as functions of gas hydrate saturation, ef...
Genome-based functional analysis suggests that micro- bial communities utilize biologically produced macro- molecules (mainly carbohydrates) as carbon and energy sources regardless of the availability of methane. The main heterotrophs are Chloroflexota, Caldatribacteriota, Verrucomicrobiota, Hadarchaeota,...
The native sediments were classified as silty sand (S1), silt (S5–S8), and clayey silt (S2–S4) (Fig. S2a, Supplementary). Coarser sediments were found in the northern Adriatic (S1), the Neretva Channel (S5), and the Albanian coastal area (S8). These environments coincide with areas...
Seamount viruses are diverse and novel In seven seamount sediment samples, a significant portion of vOTUs were classified as members of theCaudoviricetesclass, constituting ~81% of the total identified vOTUs.Caudoviricetesform a class of tailed dsDNA phages and are usually the most retrieved dsD...
Samples described in the study are classified in the top section of the Clipperton Formation (FCl). Surface sediments in the area are characterised by zonal distribution, and are represented by the following categories: (i) carbonate sediments (carbonate silts and clays, as well as carbonate ...
The soils in the Yamaguchi Bay Polder, reaching over 50% sand, are also classified as A and B in the triangle diagram, except for those in the bottom horizons in the older reclaimed polder, Yamaguchi-1. Fig. 2 Soil particle distribution using sand, silt, and clay according to Pejrup (...
Freshwater sediment microbes are crucial decomposers that play a key role in regulating biogeochemical cycles and greenhouse gas emissions. They often exhibit a highly ordered structure along depth profiles. This stratification not only reflects redox ef
