Abstract. We present laboratory experiments designed to quantify the stability and
energy budget of buoyancy-driven iceberg capsize. Box-shaped icebergs were constructed
out of low-density plastic, hydrostatically placed in an acrylic water tank containing fresh-
water of uniform density, and allowed (or forced, if necessary) to capsize. The maximum
kinetic energy (translational plus rotational) of the icebergs was 15% of the total en-
ergy released during capsize, and radiated surface wave energy was 1% of the total en-
