Sector 10. Micronesia, Palau, and Guam

February through April are the driest months. Two-thirds of

the rainfall occurs in May through October. July, with an aver- age of 480mm, has the maximum of any month.

Tides—Currents.—The E countercurrent, between the Re-

public of Palau and 2°N, is experienced throughout the year. Velocities up to 2 knots have been frequently experienced and velocities between 2 knots and 3 knots have been reported. Currents in the Palau area are variable and attain velocities

10.40

of 1 to 1.5 knots. Eastward of the group the current usually sets S, but E or NE currents, with the same velocities, have been reported. A W set prevails N of the group. Northwest and W currents have been reported W of the group.

Local and tidal currents in the vicinity of Ngeaur are ex- tremely variable. In the channel between Ngeaur and Peleliu, W currents of 3 to 4 knots have been reported at spring tides. An earlier report stated that the currents set E through the channel at the same velocity. East sets of 1.5 knots have been reported S and E of Ngeaur. Northwest sets have been reported W of the island.

The shape of the reef influences the tidal currents off the E

and W sides of the islands of Palau. In the various channels and passages, the tidal currents turn at the time of HW and LW.

10.41 Ngeaur (Angaur) (6°54'N., 134°08'E.), the S island of

Palau, is densely wooded and rises to a height of 61m on its NW side. A tower stands about 0.1 mile within the E end of the island; another tower is situated about 0.4 mile farther W. An old lighthouse is situated 0.2 mile S of the N end of the island. A white shrine stands on the NW point of the island.

10.41

A former Loran station is situated on the NE side of the

island. The buildings and nearby airfield are conspicuous. A red water tower stands near the center of the island.

of the island.

In 1990, it was reported that a light is shown from the S end Ngeaur Harbor is located on the W side of the island. It was

the site of a phosphate mining and loading operation. All these facilities have deteriorated and fouled the harbor. A small craft basin is situated on the W side of the island near the main settlement. During the season of W winds, a heavy swell sets in and the harbor is unsafe.

10.41

Anchorage.—Anchorage cannot be taken at Ngeaur; how-

ever, a vessel 55m in length has reported anchoring (1985) about 309°, 0.75 mile from the island’s SW extremity, in a depth of 16.4m. Although the vessel reported anchoring under favorable weather conditions, this anchorage cannot be recom- mended. A vessel has anchored on Hydrographer Bank, but reported a strong set and a risk of dragging.

10.42 Peleliu (7°00'N., 134°15'E.) lies at the S end of the

reef enclosing the Republic of Palau. The major portion of the island is low and level, but the central and N portions contain numerous high rock ridges. Mangrove swamp areas, extending N and S, divide the island, except for a minor strip on which the single E-W road is built. The coastline is mostly rocky, but has about 2 miles of scattered sandy beaches. Peleliu is heavily wooded. On the SE side of the island, there is an airfield. A causeway extends from the SW side of Peleliu Island.

10.42

Several small craft berthing facilities are situated on the NE side of the island.

10.43 Eil Malk (7°09'N., 134°22'E.) is a wooded island

with an irregular coast, except on the E side, where there is a range of hills about 91m high. A hill, 114m high and wooded on its summit, stands nearly 1 mile S of the N end of the island; the hill is prominent from the S. The SE end of the island is 83m high; its E side, which appears gray, is prominent. Schonian Harbor, parts of which have been swept to 16.7m,

10.43

is an open area, surrounded by reefs, situated off the SW side of Eil Malk.

10.43

Denges Passage, which leads into Schonian Harbor from the

E, is entered between the reef enclosing Ngeregong islet and the reefs extending from and fronting the S side of Eil Malk. The islet is wooded and low. The passage has been swept to a least depth of 7.9m. Denges Passage has a mean width of 90m and charted depths of 10.1 to 37m. The passage opens to an extensive area known as Schonian Harbor. Inside the harbor there are isolated coral heads. The reefs on either side of the passage and in the harbor are reported to be identifiable under favorable conditions of light.

10.43

Tides—Currents.—Currents setting NE are reported off

Denges Passage. They flow at a velocity of 1 to 1.5 knots. Off the E central coast of Peleliu, the currents attain velocities of 1.5 to 2 knots.

10.43

In the entrance of Denges Passage, the flood current sets NW

at a velocity of 2.5 knots; the ebb current sets SE at a velocity of 2.25 knots. In the narrow W part of the passage, these cur- rents attain velocities of 3.5 knots.

Slack water, which lasts about 40 minutes, ends at about the times of HW and LW at Malakal Harbor.

10.43

It is reported that the current at the W end of the passage sometimes crosses the course.

10.43 10.43

Anchorage.—Anchorage can be taken in Schonian Harbor,

good holding ground. Except for scattered shoals, the charted depths are 18.3 to 37m.

10.44 East of Eil Malk is a large irregular-shaped area en-

tered E through two swept channels. The area has been swept to 16.7m, except for scattered shoals swept to lesser depths. These can usually be distinguished by discoloration.

10.44

The S channel, entered between the reefs E of Eil Malk, has

several shoal spots of 6.4 to 9.1m at the entrance, but at the S part a channel, 0.1 mile wide is swept to 11m.

10.44

The N channel, entered between the reef extending S from

the SE end of Urukthapel Island and the two large drying reefs to the S, has a least charted depth of 7.3m and has been swept to various depths over a width of 0.5 mile. The drying reefs, when uncovered, are white.

10.44

Tides—Currents.—In the S channel, the flood sets NW at a

velocity of 1.25 knots while the ebb sets SE at a velocity of 1.5 knots. The tidal currents in the central part of the anchorage are irregular and apparently weak.

10.42

Barnum Bay (7°06'N., 134°16'E.) is an indentation in the

coastal reef and is entered about 3 miles N of Peleliu. The bay is nearly 1 mile wide at its entrance and extends about 2 miles NE. Depths in the bay are considerable, and the reef shores are steep-to. Several small islands are located on either side of the entrance, which is further marked by a white beacon on each side.
