Abstract
The report reviews information from several years of permit-required field monitoring of the physical and biological effects of solid-fill gravel causeways in the Beaufort Sea near Prudhoe Bay, Alaska. The shallow nearshore zone of the Beaufort Sea coast in the Prudhoe Bay area functions biologically as an estuary. Area anadromous fish rely heavily upon the comparatively moderate estuarine conditions in this zone. Prudhoe Bay area causeways have been constructed across this critical zone, degrading the nearshore estuarine environment by: (1) deflecting fresh and brackish water masses offshore, resulting in the loss of thermal energy and fresh water from the nearshore; (2) causing enhanced upwelling and intrusion of marine water directly into the nearshore zone in replacement of the deflected estuarine water; and (3) affecting local ice dynamics. These physical effects increase the risks that populations of anadromous fish will be seriously affected by increased overwinter mortalities, reduced growth and fecundity, and/or delayed maturation. Evidence that these impacts may already have begun to occur is discussed. Construction of additional causeways in the area would further increase these risks.
