The calcite content is very low (<15 %); quartz and plagioclase contents are 20 25 % and quasi-constant (Expedition 316 Scientists 2009) (Fig. 8).
The lithostatic pressure was estimated from a density curve that was in turn calculated from resistivity logging data, assuming a constant grain density of 2.50 g/cm3 (Expedition 343/343T Scientists, 2013).
But it is considered more probable that he was murdered by one of the other members of the expedition, possibly Bessels, who was in nearly constant attendance of Hall.
When he came to a river swollen with the constant torrential rains that had been falling during the expedition, Cortés turned upstream to the Gracias a Dios rapids, which took two days to cross and cost him more horses.
If small-scale warfare during the 4th and 5th centuries rarely erupted into major expeditions, the threat to Rome nonetheless remained constant, demanding vigilance and the construction of satisfactory fortifications.
It was noted as early as the "Challenger" expedition that the salt dissolved in seawater has remarkably constant major constituents.
Worsley remained in near constant contact with Shackleton, who was attempting to put together an expedition to the Arctic, and was hopeful of securing a suitable position in the endeavour.
At depths deeper than 200 m bsf at all sites drilled during Expeditions 315 and 316, δ18OH2O and δDH2O were nearly constant: δ18OH2O varied between −4.5‰ and −2‰, and δDH2O varied between −15‰ and −10‰ (Figure 4).
Death is a constant for any climber, and something I think very seriously about before every expedition.
It meant that during the whole expedition we had to establish the route ourselves … and we had this constant concern that we didn't know if it was physically possible to reach the summit".
It's an expedition where your plans, safeguards, and policing are hollow because the road is less traveled and failure is constant.
