Atmospheric Nitrogen Inputs into the Coastal Ecosystem (ANICE): The Southern North Sea as a Study Area

The Atmospheric Nitrogen Inputs into the Costal Ecosystem (ANICE) project was initiated to improve the accuracy and performance of model tools used to estimate the atmospheric nitrogen deposition to the sea. The experimental work includes the use of a ferry for long-term measurements of gaseous species, aerosols and rain water during one year, and two intensive field campaigns. During the first ANICE intensity experiment, situations were encountered in which the air flow connected the different stations. Differences in nitrate and ammonium concentrations between the various stations were analyzed in terms of the processes determining the concentrations of these species and to quantify their variations with fetch.
