Seymour Island
Seymour Island or Marambio Island, is an island in the chain of 16 major islands around the tip of the Graham Land on the Antarctic Peninsula. Graham Land is the closest part of Antarctica to South America. It lies within the section of the island chain that resides off the west side of the peninsula's northernmost tip. Within that section, it is separated from Snow Hill Island by Picnic Passage, and sits just east of the larger key, James Ross Island, and its smaller, neighboring island, Vega Island.
Seymour Island is sometimes called Marambio Island or Seymour-Marambio Island, taking its resident Argentine base as its namesake (see section, Base Antárctica Marambio, below).
The US Defense Mapping Agency's Sailing Directions for Antarctica (1976) describes Seymour Island as follows:
Seymour Island lies northeastward of Snow Hill Island, from which it is separated by a strait about 1 mile wide. Strong currents and tide rips exist in this channel which shoals to less than 1.8mi (1 nm) in the center of the channel at low tide. The bottom deepens steeply on the northwestern side of the channel. The Island is 8 miles long and about 4 miles wide opposite Bodman Point (Cape Bodman) on the northwestern coast; the ends on the island are about 2 miles wide. It is entirely snow-free and of remarkable appearance. The northern portion of the island is a high, level, extensive plateau which reaches an elevation of 591 feet. Below this smooth plateau are terraces containing valleys and small irregular knolls of hard rock.
A transverse valley, the bottom of which is not much above sea level, cuts through the island from east to west. This valley opens into Papua Beach (Penguin Bay) on the eastern shore, and into an unnamed bay on the opposite shore east of Bodman Point. From Papua Beach to the northeastern extremity of the island runs a strip of deeply diffracted land. The southwestern portion of the island offers an appearance in marked contrast with the smooth surface of the northern portion. The southern half of the island has a peculiar ribbed appearance, being low and deeply dissected with many low hills between the erosive lines. Low perpendicular rock cliffs border the shore line but there are many landing places where the gorges slope gradually to the sea.
A depot of provisions was placed by Nordenskjold in 1903 at a cairn in the valley behind Penguin Bay.
A wooden plaque and rock cairn stand at Penguins Bay, on the southern coast of Seymour Island. The plaque was placed on 10 November 1903 by the crew of the Argentinian Corvette Uruguay on a mission to rescue the members of the Swedish expedition led by Otto Nordenskiöld. The cairn was erected in January 1990 by Argentina at the site of the plaque in commemoration of the same event. The site has been designated a Historic Site or Monument (HSM 60), following a proposal by Argentina to the Antarctic Treaty Consultative Meeting. The inscription on the plaque, placed where the two parties met, reads:
"10.XI.1903 Uruguay (Argentine Navy) in its journey to give assistance to the Swedish Antarctic expedition".
