Figure 5From: Biogeochemical consequences of macrofauna burrow ventilation†Model-calculated evolution of ΣCO2 near WSI and burrow wall during each rest–ventilation cycle. During the rest cycle (T1–T3), ΣCO2 within burrow cavity evolves to exceed that of adjacent sediment pore water due to metabolic ΣCO2 excretion by N. diversicolor.Back to article page
