Iro Maru

The Iro was a Japanese navy fleet oiler, torpedoed by an American submarine on the run in to Palau and then finished at anchor when carrier aircraft swept the lagoon at the end of March 1944. She sits upright, enormous and dignified, her bow gun still trained at nothing, kingposts rising toward the light and furred in black coral and soft corals. Most tours circle the deck at 22–28 m — winches, fuel piping, and the huge gun platforms — while the engine spaces reward properly trained penetration teams. Lagoon visibility is moderate, which if anything improves the atmosphere.

您此行的高光时刻: The coral-clad bow gun; kingposts silhouetted overhead; big morays and batfish patrolling the superstructure.

地形地貌: Upright hull on a silty lagoon floor at roughly 36–40 m

入水方式: Moored dive in sheltered lagoon water near Koror; descend the line to the kingposts.

危险因素: Depth and lagoon silt; residual oil and munitions in closed spaces; penetration only with wreck training and lights.

保育: A protected historic wreck of a violent chapter — artifact removal is illegal, and the site deserves quiet respect.

高氧（Nitrox）: 在此值得使用——各潜点深度落在富氧空气（nitrox）能有效延长免减压时间的区间（前提是持有相应认证）。
