Studies have shown that litter concentrates in so-called convergence zones - formed by currents and wind - where whales feed on abundant prey.

Collisions with ships, and tissue-damaging noise pollution from off-shore oil exploration are additional threats, experts note.

The IWC is riven between countries that oppose whale hunting, and those that back the handful of nations - Japan, Iceland and Norway - that defy a 1986 whaling ban or use legal loopholes to circumvent it.
