Sector 7. The Solomon Islands—East Part

to 0.6m, on its N and NE sides. At the E end of the island, the shore reef encloses a lagoon with a narrow entrance. The S part of this lagoon has depths of 7.5 to 14.6m and forms an ex- cellent boat harbor at all times. There is a coconut plantation on the island, with scattered trees from 30 to 37m high. Sura Kiki (Rua Kiki), the E island, is densely wooded and

7.28

about 43m high to the tops of the trees. A ridge, with a depth of 3m at its outer end, extends about 0.3 mile ENE from the island, which is fringed by a reef.

7.28

Papari Island (Rua Suli), the W island, is fringed by a reef

and is merely a narrow strip of reef just above HW, with trees 18 to 24m high.

7.28

North-East Reef, about 2.3 miles long, fronts the NE side of

the Rua Sura Islands and dries in patches at its NW end. It has general depths of less than 1.8m and is separated from the N side of Rua Sura by a deep passage 0.2 to 0.4 mile wide with irregular depths. The SE end of this passage is almost closed by a least depth of 5.2m. North-East Reef is steep-to on its seaward side; detached patches lie off its NW end.

7.28

North-West Reef, about 0.8 mile NW of Papari Island and

marked by a light, is 0.3 to 0.4 mile long and steep-to on all sides. Near its center is a boulder which dries 0.9m at LW, and 0.2 mile off its E edge is a small rocky 10.9m patch.

boulders.

7.28

Lark Reef and Mid Reefs dry at LW and have above-water Tides—Currents.—Guadalcanal Island tides are semi-

diurnal, with diurnal tides occurring a few days during the month.

Tidal currents set to the W and E following the coastlines of Guadalcanal Island and the Florida Islands, and attain a velo- city of 2 knots at springs. During the Southeast Monsoon, the currents are irregular. Shoals and irregularities on the bottom between Guadalcana Islandl and the Florida Islands cause strong tide rips.

7.28 7.28

Anchorage.—During the Southeast Trades, anchorage can

be taken, in 22m, sand and coral, between the W end of Mid Reefs and the coastal reef off the N side of Rua Sura, but the swinging room is limited to 110m and off-lying patches of reef exist nearly 0.1 mile from the coastal reef.

7.28

Anchorage can also be taken during the Southeast Trades, in

55m, sand and coral, about 0.3 mile NE of the W end of Papari Island.

7.29 Marau Sound, at the E end of Guadalcanal Island, is

the area enclosed by the numerous islands and coral reefs, with many deep passages between them, fronting the E end of Guadalcanal Island. The hills and valleys of Guadalcanal Is- land, as well as the islands in the sound, are all densely wooded with high dark trees common to these islands. Marau Peak (9°51'S., 160°47'E.), on the mainland W of the sound, is 702m high.

Caution.—Volcanic activity may have caused movement of the reefs and seabed in the Marau Sound area.

7.29 7.29

Extending off the islands and the mainland are barrier reefs,

which lie in a somewhat even curve and form an excellent natural breakwater. The flat coral islands scattered over the SE part of Marau Sound, and those lying off the NW part are much alike, with a flat sandy base and a thick covering of high trees. Taunu Shoal, which has a least depth of 3.6m and upon which the sea breaks at times, lies 0.75 mile E of the barrier

reef, about 3.3 miles ESE of the SE extremity of Marapa. A 9.1m patch lies about 1.8 miles N of Taunu Shoal.

7.30 Marapa Island (Malapa Island) (9°48'S., 160°52'E.),

the largest island in Marau Sound, has a ridge extending along the length of the island. This ridge rises to an elevation of 201m in a rounded summit at its N end, and is a good mark for a vessel approaching the sound from the NW.

7.30

There are several passages between the detached reefs lead-

ing into the sound, the two principal ones being South-East En- trance and North-East Entrance. The direct channel connecting these two entrances is practically clear of dangers, except at the S end, although very narrow in places.

7.30

Other channels within the sound are Runcie Pass, leading

NE from South-East Entrance, Woodhouse Passage, Avoca Channel, Cormorant Entrance, and several others.

7.30

South-East Entrance, between the reef extending E from a

point about 0.5 mile SSW of Graham Point (9°51'S., 160°50'E.), the E extremity of Guadalcanal Island, and the reef on which Rauhi Island (Entrance Island)(9°52'S., 160°53'E.) lies, is almost 0.8 miles wide and clear of dangers, except for Emerald Rocks, lying about 1 mile within the entrance. These rocks, lying about 1 mile ESE of Graham Point, consist of two patches with a least depth of 3.2m. Unless these rocks are properly marked, no vessel without local knowledge should attempt the South-East Entrance, except with the sun in a favorable position.

7.30 7.30

Range lights, in line bearing 006.5°, mark the entrance. North-East Entrance is about 0.8 mile wide between Beaver

Shoals, 0.6 mile NE of Maruiapa Island, and the barrier reef lying about 0.8 mile N of Marapa Island. The sea sometimes breaks on Beaver Shoals, but the other reefs show well. Between the entrance and Harbor Reef, off the entrance of Danae Bay, the outstanding danger is the reef on which the Wilson Islands lie, but in the entrance itself there is a small rocky patch with a least depth of 16.5m, nearly in mid-channel, and about 0.3 mile ESE of Beaver Shoals.

Range lights for North-East Entrance are shown from the reef W of Keura Island. The lights in line bear 203°.

7.30 7.30

Passage can be made through Marau Sound by entering

North-East Entrance, then pass W of the Wilson Islands and their surrounding reefs, then pass between Wahere Island (Ko- mancho Island) and Tawaihi Island (9°50.0'S., 160°50.5'E.), then pass between Maraunibina Island (9°50.7'S., 160°50.3'E.) and Emerald Rocks (9°51.1'S., 160°51.0'E.), taking care to clear their surrounding reefs. Vessels then leave by way of South East Entrance. Passage from S to N is by the reverse route.

7.31 Cormorant Entrance (9°49'S., 160°54'E.) leads into

Marau Sound from the E. Passage can be made through to a junction with the passage between North-East Entrance and South-East Entrance, mentioned above in paragraph 7.30, via Woodhouse Passage (9°50'S., 160°52'E.), which is S of Mara- pa Island.

7.31

Tides—Currents.—The tidal currents in Marau Sound are

strong and irregular, depending on the season of the year. The currents run through the deep passages with a velocity of 1 to 4 knots, sometimes retaining the same direction for several days.
