Sector 4. The Kiribati Islands to the Marshall Islands

Bock Pass, on the W side of the atoll, is divided into several

unmarked channels by detached shoals and reefs. The middle channel, which has a least depth of 21.9m, is preferred. There are patches, with depths of 5.5 to 7.3m, near the fairway. The pass is hard to identify from offshore.

4.73

Jedibberdib Pass, at the N side of the atoll, is shallow and

suitable only for small vessels with local knowledge. The pass is to be used under only the most favorable conditions. It has been swept to a depth of 3.6m. A heavy swell rolls in during strong NE winds.

4.73

Anchorage.—Small vessels, with local knowledge, can

anchor, in 27.4m, sand, about 0.3 mile off the lagoon side of Eniwetak Pass. Care must be taken to avoid the reefs, which are hard to identify due to their dark brown color.

4.73

Caution.—The S end of the atoll is difficult to identify,

except under the most favorable conditions, as there are no islands or sand cays. The reef fringing the seaward side of Bock Island (11°23'N., 167°22'E.) bares at LW to a distance of 0.25 mile offshore. Navigation within the lagoon is dangerous, except under favorable conditions of light.

4.74 Rongelap Atoll (11°09'N., 166°54'E.), lying about 18

miles W of Rongerik Atoll, consists of a number of small sandy islets, most of which lie on the E side of the atoll. Rongelap Island, Eniaetok Island, and Burok Island (Burokku Island) are covered with coconut palms; the rest of the islets are very sparsely wooded. A church and a small village has been built on Rongelap Island. Native crafts are obtainable. There are nine entrances into the lagoon, three on the E side,

4.74

four on the S side, one on the W side, and a small boat passage on the N side. South Pass, Kaeroga Pass, Northeast Pass, and Enybarbar Pass (Enibarubaru Passage) are considered to be the best and most important. The approaches to these passes are clear and can be readily identified under favorable conditions of light.

4.74

Tides—Currents.—The tidal currents in South Pass attain a

rate of 1 knot on the flood and 1.35 knots on the ebb. They appear to turn at about the time of HW and LW. In 1979, an extremely strong W set was reported while entering the South Pass to Rongelap Atoll lagoon during ebb tide. With a ship’s speed of 10 knots, a heading 014° to the right of track was necessary to maintain course.

4.74

Strong currents are reported in Bikien Pass (Pigen Pass)

(11°10'N., 166°45'E.) and other narrow passes. Most of the water enters through the E passes and flows out through West Pass (11°21'N., 166°38'E.) and Kaeroga Pass. It was reported that there were strong flood currents in West Pass and Kaeroga Pass.

4.74

Depths—Limitations.—Numerous sunken rocks lie in the

lagoon. An area, swept to 14.9m and having shoal spots swept to lesser depths, exists along the E part of the lagoon. It was reported that the NE part of the lagoon was strewn with reefs. It was further reported that the W portion of the lagoon appeared to be navigable, and to be free of coral heads, except for those lying quite close to the atoll reef.

4.74

Aspect.—South Pass is about 3.5 miles wide, but shoals

divide the pass into several unmarked channels. The deepest channel has depths of 32.9 to 51.2m, and lies about 1.5 miles WNW of Rongelap Island. This channel has been swept to 14.9m. When the sun is high, the deep water portion of South

4.75 Ailinginae Atoll (11°07'N., 166°32'E.) lies about 7.5

miles WSW of the SW extremity of Rongelap Atoll. The atoll bares at LW and consists of a number of tree and bush-covered islets, most of which lie on the S and E sides. Coconut palms, trees, and moderate undergrowth are found on the S islands, and sparse undergrowth is found on the E islands. The shores of the islands are rocky, but there are a few sandy beaches. Sifo Island (11°08'N., 166°18'E.), on the S part of the W extremity, was reported as being visible from S from a distance of 16 miles, both visually and by radar.

4.75

Aspect.—Mogiri Pass, on the S side of the atoll about 2

miles from its W extremity, is the main entrance into the lagoon. In 1963, an examination of Mogiri Pass showed a least depth of 7.3m in the fairway. The lagoon appeared to have depths of 10.7 to 18.3m, except in the E part where several sand bars were noted.

4.75

On the E side of Mogiri Island, at the E side of Mogiri Pass,

is Eniibukku Pass. It is encumbered with rocks and should only be used by small vessels with local knowledge.

4.75

Anchorage can be taken about 0.3 mile N of Mogiri Island,

where it is fairly calm. The wind, at times, causes a heavy sea. 4.76 Bikini Atoll (11°30'N., 165°34'E.) consists of over 20

islands and islets lying about 46 miles WNW of Ailinginae Atoll. Bikini Island (11°37'N., 165°33'E.), covered by a dense growth of coconut palms and having a few buildings on it, is the principal island of the group. Some coconut palms also grow thickly on Enyu Island, about 4.5 miles S of the S ex- tremity of Bikini Island. Three piers, each about 69m long, are situated on the SW side of Enyu Island. Bikini Atoll, from 1953 to 1971, was used as an atomic proving grounds.

Pass can be clearly distinguished from a position 1.5 miles to seaward. Between this channel and Rongelap Island, there are other channels which have been swept to various depths, within the limits shown on the chart.

4.74

Kaeroga Pass, about 9 miles WNW of the W extremity of

Rongelap Island, is reported to be deep and clear. The channel, which shows clearly in contrast to the reefs on either side, is about 0.8 mile wide and has a reported depth of 27.4m. Numerous coral obstructions were reported (1963) to lie up to 1 mile N of Eniran Island (Enigan Island). The lagoon area within the entrance is reported to be clear of shoals, but no soundings are shown on the chart.

4.74

Northeast Pass, about 6 miles NE of Eniaetok Island

(11°17'N., 166°54'E.), is about 0.5 mile wide. It has a least depth of 18.3m in the fairway, and has been swept to 14.9m over a width of 0.2 mile. Large vessels may use it. Vessels wishing to enter should steer for the E of two low islets on the atoll reef opposite the pass, on a course of about 335°. Enybarbar Pass (Enibarubaru Pass), reported to be suitable

4.74

for large vessels, has been swept to a depth of 14.9m on the W side and 10.6m on the E side, in 1927. A shoal, with a least depth of 11.9m, lies in mid-channel.

4.74

Anchorage.—Vessels can anchor, as convenient, in the

swept areas of the lagoon. Vessels can anchor in a position about 0.8 mile off the lagoon side of Rongelap Island. Anchor- age can also be taken off the N side of Mellu Island, located on the E side of Northeast Pass.
