Long-distance electrical conductance in sediment was first observed in 2010 as a spatial separation of sulfide oxidation and oxygen reduction in marine sediment that was interrupted and re-established at a rate faster than could be explained by chemical diffusion.
Langdistance elektrisk konduktans i sediment blev første gang observeret i 2010 af forskere fra Aarhus Universitet som en rumlig adskillelse af sulfid oxidation og oxygen reduktion i marin sediment i Aarhus Bugt (Aarhus Havn), som i laboratoriet blev afbrudt og re-etableret med et hastighed hurtigere end som kunne forklares ved kemisk diffusion.
