As Joshua Hill, over at Plantsave has eloquently said,

Dead zones are created, in the beginning, by nitrogen (among other things). Nitrogen is the byproduct (in this instance) of natural gas transformed in to ammonia fertilizer, which is then spread across the agricultural landscape of many western and emerging nations.

From there the runoff makes its way to streams, then rivers and finally the oceans. It is at this stage upon reaching the ocean that the real trouble begins.
