Iony Island (Russian: Остров Ионы), or Jonas' Island, formerly Ostrov Svyatogo Iony (Saint Jonas' Island), is a small island in the Sea of Okhotsk. It is 1.6 km (1 mi) in length and 850 m (0.5 mi) wide and it has a conical shape.
Iony Island is the only island in the Sea of Okhotsk that is located in the open sea. All other islands in the Okhotsk Sea are either coastal islands or they belong to the Kuril island chain.
As early as 1849 whaleships had reached Jonas Island. Between 1852 and 1866 the island's waters were a common hunting ground for ships cruising for bowhead whales — Captain Moses Snell, of the ship Pacific, of Fairhaven, reported seeing as many as forty-five other ships from his masthead early in June 1855. The fleet would usually reach the area by late May or early June, spending a few weeks cruising for whales before sailing to the south and west, following the retreating ice. Some would go ashore to take advantage of the bounty of seabirds and pinnipeds residing on the island's rocky shores. In the first week of June 1855 the ship Edgar, of Cold Spring, was wrecked on the island. All hands were saved. Ships sent boats ashore to salvage what they could of the reported 1,600-bbls of oil that had been aboard the ship, while others picked up whatever they found drifting offshore.
