摘要:
ABSTRACTIn the context of ecosystem modeling, a brief description is given of preliminary results from evaluating the spatial and temporal distribution of conditions favourable for resuspension at the bottom of the Kattegat. Two maps are presented: (1) the water depth at which the wave base is capable of penetrating for a given time-frequency; this is a function of fetch and wind characteristics, (2) the theoretical time-frequency of wave base presence at the bed, primarily a function of the water depth. Here, the influence of fetch is demonstrated in the filtering effect of archipelagos. A division of the Kattegat into four regions with characteristic wave impact climates at the bed was made: the deepest part (NE) is calm because of its water depth; the SamsøBelt (SW) is calm because of limited fetch within the archipelago; a relatively deep area (SE) experiences recurrent resuspension because of long fetch, and the shallowest part (NW) is frequently resuspended despite relatively limited fetch.
