- Abstract:
- Nitrogen is key to life on earth, cycling between the atmosphere, life (animals, plants, microbes) and back to the atmosphere following decomposition. Until recently, oxygen (which links decomposition with the atmosphere) was considered vital to this cycle. The laboratory discovery that the cycle could be completed in the absence of oxygen via anaerobic ammonia oxidation (anammox) redefined this classical view. We have shown that anammox occurs in the environment by measuring its activity in sediments from along the Thames estuary; though our pattern of its distribution is different to that reported for marine sediments. The advent of anammox in the environment changes our perspective of the global nitrogen cycle, yet what regulates its activity or indeed its distribution in aquatic sediments remains unknown. We will use state of the art techniques to trace the movement of nitrogen (isotopes) through this novel process in sediments from the south western approaches to the Irish Sea and several local estuaries, with the aim of elucidating the factors that regulate its activity in these two contrasting environments. The programme, at a cost of #183,016, will employ 2 members of staff for 3 years and addresses several areas of research covered by the Marine Sciences Committee.
