Horizontal and vertical gradients in sediment nutrients on mudflats in the Shannon estuary, Ireland

Abstract

Spatial variability in nutrient concentrations in the intertidal sediments and pore waters has been studied along downshore transects and in core profiles at three locations in the Shannon estuary on the west coast of Ireland. The parameters measured were N, as Kjeldahl N, NO3, NO2, and NH3, and P as total P and PO4 along with a range of other environmental variables such as salinity and sediment organic content.
