13. ABSTRACT (Maximum 200 words)
Winter tests of artillery firing were conducted in the Eagle River Flats impact range to determine the physical
effects of exploding high-explosive (HE) projectiles on the ice-covered terrain. Eagle River Flats is an estuary at the
mouth of the Eagle River used as the artillery impact range for Ft. Richardson. The Army suspended use of the
impact range following the discovery that white phosphorus (WP) deposited in the salt marsh was responsible for
large numbers of waterfowl deaths each summer. The purpose of these tests was to assess if seasonal firing of HE
projectiles from 60- and 81-mm mortars and 105-mm howitzers into Eagle River Flats could be resumed without
significantly disturbing the sediments contaminated with WP. The results of the test firings indicated that a
minimum of 25 cm of ice over frozen sediment or a minimum of 30 cm of floating ice over shallow water was
required to prevent disturbance of the WP-contaminated sediment by exploding 105-mm howitzer projectiles.
Only 10 cm of ice was required to prevent disturbance by exploding 60- and 81-mm mortar projectiles.
