 measures 30.12 square miles (78 km²). It consists of 36 islets.The total area is 49.8 square miles (129 km²) (including reef flat).

Physical Features

The atoll is roughly crescent-shaped, measuring about 11 miles (17.7 km) by 5.6 miles (9 km), and oriented in a north-south direction. The atoll reef is unbroken except for a 22 yards (20.1 m) wide channel in the west. Ten islets lie on the eastern and southeastern reef. The more important named islets, from north to south, are North Island, Kamwome, Bwdije, Sibylla, Bokak, and Bwokwla. Sibylla is the largest, measuring approximately 4.5 miles (7.2 km) in length and up to 333 yards (304.5 m) in width. Kamwome Islet to the north-east of Sibylla is the second largest, while Bokak (Taongi), after which the atoll is named, lies to the south of Sibylla.

 rock base. As most local coral growth stops at about 150 feet (45.7 m) below the ocean surface, such a massive stony coral base suggests a gradual isostatic subsidence of the underlying extinct volcano, which itself rises 10000 feet (3,048 m) from the surrounding ocean floor. Shallow water fossils taken from just above Enewetak's basalt base are dated to about 55mya.

High boulder and sand ridges indicate a history of severe storms and are a feature of the islets. Inland on the wider islets are sand and rubble flats, while back from the lagoon sides are low sand and gravel ridges. Soils are mostly very immature, a mixture of coarser coral sand and gravel of various textures with very little humus accumulation. The lagoon is shallow, probably not exceeding 30 metres (98.4 ft) depth, and has many coral heads and patch reefs, some reaching the surface.

The lagoon water level is up to 0.9 metres (3 ft) higher than the surrounding ocean due to an influx of wind-driven waters over the windward ocean reef and the presence of only one narrow reef passage on the leeward side. Water cascades over the coral-covered rim and flats of the sloping leeward reef. A massive algal ridge lines the outer edge of the windward reef, while the south and west reefs are coral-covered narrow flats where landings can be made in quiet weather. A very small algal rim, 4-6" (100–150 mm) high, on lagoon shores of the westernmost islets, on east-facing lagoon reef-fronts and on the windward edges of coral patches in the lagoon, may be a feature unique to Taongi. This rim is maintained by the constant flow of water over the reef flat.

Climate

Bokak is the driest of the Marshall Islands atolls, having a semi-arid character. Mean annual temperature is approximately 82 °F (27.8 °C). Mean annual rainfall is less than 40 inches (101.6 cm), and falls primarily during the late summer. Prevailing winds are north to north-easterlies.

Vegetation

Bokak supports just nine plant species. All are native to the Marshall Islands and entirely undisturbed by introduced species

Prehistory

Although humans migrated to the Marshall Islands about 2000 years ago, there appear to be no traditional Marshallese artifacts present that would indicate any long term settlement. The harsh, desiccated climate, lack of potable water, and poverty of the soils indicate that the atoll will probably remain uninhabited. The atoll has traditionally been used for hunting and gathering, particularly sea birds, by inhabitants of other atolls in the northern Ratak chain.

 in 1906. Using the justification that uninhabited atolls were unclaimed, the Germans seized Bokak as government property, despite the protests of the Iroji. As Japan's economic vigor expanded under the Meiji Emperor, the German administration noted Marshallese complaints of Japanese bird poaching, more from the view of protecting German sovereignty, rather than the interests of the islanders.
