Rongel Reef is a moraine
reef
in the Emona Anchorage
in the eastern parts of Livingston Island in the South Shetland Islands
, Antarctica. The reef emerged during a glacier retreat in the late 20th and early 21st centuries.
The reef extends over 600 m (656 yd) in northeast-southwest direction and is partly exposed at low tide and submerged at high tide but for the islet rising to near 3 m (9.8 ft) at its northeast extremity.
Its midpoint is located 2.85 km (1.8 mi) north-northwest of Hespérides Point
, 3.12 km (1.9 mi) west of Aleko Point
, and 3.35 km (2.1 mi) northeast by east of Ereby Point
. The northeast extremity of Rongel Reef is located 75|m|yd|0|abbr=on}} south-southwest of Rongel Point
. A 710 m (776 yd) wide nameless cove is indenting for 250 m (273 yd) the coast behind Rongel Reef, the northeast side of its entrance formed by Rongel Point. The southwest extremity of Rongel Reef is located 300 m (328 yd) southeast of the nameless point located 3.18 km (2 mi) northwest by north of Hespérides Point and 3.04 km (1.9 mi) northeast by east of Ereby Point.
The feature is named after the Brazilian Navy
ship Ary Rongel, in recognition of her logistic support for the Bulgarian Antarctic programme.
