The archaeologists have filled in and covered over High Command Redoubt, the site of German trenches on a nearby ridge, and turned the land back to the farmer who owns it.
The slabs are telling us the sites of past ocean trenches and the locality of island arcs, which are the building blocks of continents," said Mihalynuk, a geologist with the British Columbia Geological Survey in Canada.
The ruins of Old Sarum in Wiltshire are an unlikely Somme; but while few of English Heritage's sites would support the digging of trenches, Sarum's walled remains have lent themselves to the job.
From 1960 to 1968 radioactive waste, including several grams of Pu, was disposed in a series of trenches at this site by the former Australian Atomic Energy Commission (AAEC).
The Dubrum site — which stretches for miles in a sparsely populated region — is pocked by hundreds of trenches, some deeper than 10 or 12 feet.
They talk of trenches and flanks.
Based on this analysis, we identified a suitable site for trenching, and compiled the trench-log stratigraphy at this site.
If each trench has a 500 tC capacity (example in Fig. 6), then the number of trenches needed for a 5 GtC y-1 sequestration rate would be 10 million per year, i.e., one trench every 3 seconds.
The total resorbed surface was presented as the percentage of the total bone surface, and the trenches, as percentage of trenches per total resorbed surface.
The low permeability of the clay-rich soils is the major factor causing the 'bathtub' effect at the site, leading to surface release of trench-water, which has elevated Pu and Am levels (Table 1).
