Benjamin Morrell
 At her own insistence, and against Morrell's and the owners' advice, his wife Abby Jane Morrell accompanied him. By January 1830 "Antarctic" had reached the Auckland Islands, south of New Zealand, where Morrell had hoped for a rich harvest of seal, but found the waters empty. He sailed north for Manila in the Philippines, hoping to find a commercial cargo there, and arrived in March 1830. No such cargo was available, but Morrell was persuaded by the American consul, George Hubbell, that a potentially profitable enterprise would be to collect sea cucumbers (otherwise known as "Bêche-du-mer"), plentifully available in the islands now known as Micronesia. These could then be taken to China where they were much prized.

Benjamin Morrell [SEP] Fourth voyage: South Seas and Pacific Ocean
According to Morrell, "Antarctic"'s owners were unanimous that he should make another voyage with the ship, and in September 1829 "Antarctic" left New York, bound for the South Atlantic and Pacific in search of seals. At her own insistence, and against Morrell's and the owners' advice, his wife Abby Jane Morrell accompanied him. By January 1830 "Antarctic" had reached the Auckland Islands, south of New Zealand, where Morrell had hoped for a rich harvest of seal, but found the waters empty. He sailed north for Manila in the Philippines, hoping to find a commercial cargo there, and arrived in March 1830.
