Average litter abundance per transect ranges from 1.2 items/10 m in Sant'Agata channel at ~300 m depth, to 13.2 items/10 m in Tremestieri channel 1 at 520 580 m depth (Table 1).
Subsequently, a total of 2,234 virus-like particles were sorted by FAVS from environmental seawater samples collected from the Atlantic Ocean during the Malaspina expedition (bathypelagic, 4,000 m depth) and from the Mediterranean Sea (surface and deep chlorophyll maximum, 60 m depth) (Table 1; Supplementary Figs 2–4).
Although grain yield had no planting date x seeding depth interaction (P=0.06), the early April planting date did show a quadratic response to seeding depth with the 1.5 inch depth yielding 211 bushels/acre compared to only 189 bushels/acre for the 3.0 inch seeding depth (Table 2).
Nevertheless, soybeans at two farms (Livingston and Tomkins Co.) showed pronounced negative linear responses to seeding depth for early plant populations as indicated by ~9,000 to ~17,000 fewer plants/acre at the 2.5 vs. 1.0 inch seeding depth (Table 3).
Finally, we found unique soil conditions in the transition layer (7-to-12 inch depth, Table 1) where the relative benefits from the treatments were different from the other layers, because the surface residue is placed at this depth under Plow-till.
Figure 5 shows that measured 10Be and 26Al concentrations decrease exponentially with depth (Table 3).
Well K_D1 samples show depletion in oxygen down the depth (Table 2).
The highest value of vitrinite reflectance was 1.132 at 520 m depth (Table 3).
In all land uses considered in this study, total N decreased consistently with soil depth (Table 5).
Five planktonic foraminifera samples were extracted from the sediments of C0018 (between 0.2 and 1.4 m depth; Table 2) for radiocarbon dating.
The results of amorphous Fe and Al, extracted with ammonium oxalate, increased with depth (Table 3) and are positively correlated with clay content (r2 = 0.90 and 0.96, respectively).
