St Aubin’s Bay Organic Nitrogen, Carbon and Phosphate Study 2017

​A key recommendation from the report 'A gap analysis of the research and monitoring of nutrient pressures affecting St Aubin's Bay' (Cefas) is to establish the organic carbon, nitrogen and phosphate (OCNP) held within the sediment of St Aubin's Bay.  Obtaining this data is important because nutrients stored within the sediment can prolong the occurrence of opportunistic seaweed, Ulva, even after effective nutrient reduction is implemented and is an important component of the recommended modelling process.

The results of this study showed relatively low levels of N (and organic carbon) held within the sands of St Aubin's Bay, despite high nutrient inputs in to the adjacent water column and large accumulations of seaweed deposited along the strandline during summer months.
