Microbial sensors detect microbial activity in the seafloor sediment indirectly by measuring redox (reduction-oxidation) reactions. For instance, a microbial sensor package that was installed at Barkley Canyon in 2010 aimed to reveal the decomposition process occurring within the sediments. During certain periods of the year, production of organic matter in the upper water column increases and more food reaches benthic creatures as nutrients sink from surface. At Barkley Canyon, influx of organic matter occurs during the spring (April to May) and in the fall (August to October). Together with other co-located instruments, microbial sensors can improve our understanding of benthic ecosystems.
