Melting Ice and Warmer Temperatures Linked to Massive Oxygen Loss in the World's Oceans

It turns out that about 10,000 to 17,000 years ago, there was a massive loss of oxygen in the ocean when ice sheets abruptly melted. The new findings could explain similar changes that are occurring in the ocean today.
