Red pencil urchin – Papahānaumokuākea. The Papahānaumokuākea Marine National Monument (PMNM) (roughly / p ɑː p ɑː ˈ h ɑː n aʊ m oʊ k u ˌ ɑː k eɪ. ə / [2]) is a World Heritage listed U.S. national monument encompassing 583,000 square miles (1,510,000 km 2) of ocean waters, including ten islands and atolls of the Northwestern Hawaiian Islands.
With its boundaries including waters from the shoreline to depths of 600 feet (180 m) in many areas, the sanctuary encompasses a variety of marine ecosystems, including seagrass beds and coral reefs. Much of the sanctuary has fringing coral reefs close to shore and deeper coral reefs offshore. Hawaii's coral reefs are noted for their isolation.
Like the rest of the Hawaiian Islands, the atoll observes Hawaii Standard Time. In total, Pearl and Hermes has about 32 ha (80 acres) of land and almost 80,937 ha (200,000 acres) of coral reef habitat. [2] The fringing coral reef which surrounds the atoll is roughly 43 mi (69 km) in circumference and open to the west. [1]
Coral Reef Conservation Program (CRCP) is a partnership between National Oceanic and Atmospheric Administration (NOAA) agencies, established in 2000. The program is a multidisciplinary approach, initiated by the NOAA, to managing and understanding coral reef ecosystems through research and the publication of data to support relevant partners involved in coral reef restoration.

Maro Reef (Hawaiian: Nalukākala - "surf that arrives in combers") is a largely submerged coral atoll located in the Northwestern Hawaiian Islands. It was discovered in 1820 by Captain Joseph Allen of the ship Maro, after whose ship the reef was named.
Along coastlines from Australia to Kenya to Mexico, many of the world's colorful coral reefs have turned a ghostly white in what scientists said on Monday amounted to the fourth global bleaching ...
The island has two peaks, 272 m (892 ft) Miller's Peak in the west, and 259 m (850 ft) Tanager Peak in the east. Nihoa's area is about 171 acres (0.69 km 2) and is surrounded by a 142,000-acre (57,000 ha) coral reef. Its jagged outline gives the island its name, Nīhoa, which is Hawaiian for "toothed, serrated".
