State of the Coral Triangle: Solomon Islands
State of the Coral Triangle: Solomon Islands One of a series of six reports on the status of marine resources in the western Pacific Ocean, the State of the Coral Triangle: Solomon Islands describes the biophysical characteristics of Solomon Islands’ coastal and marine ecosystems, the manner in which they are being exploited, the framework in place that governs their use, the socioeconomic characteristics of the communities that use them, and the environmental threats posed by the manner in which STATE OF THE CORAL TRIANGLE: they are being used. It explains the country’s national plan of action to address these threats and improve marine resource management. Solomon Islands About the Asian Development Bank ADB’s vision is an Asia and Pacific region free of poverty. Its mission is to help its developing member countries reduce poverty and improve the quality of life of their people. Despite the region’s many successes, it remains home to approximately two-thirds of the world’s poor: 1.6 billion people who live on less than $2 a day, with 733 million struggling on less than $1.25 a day. ADB is committed to reducing poverty through inclusive economic growth, environmentally sustainable growth, and regional integration. Based in Manila, ADB is owned by 67 members, including 48 from the region. Its main instruments for helping its developing member countries are policy dialogue, loans, equity investments, guarantees, grants, and technical assistance.

The AREA's RICHNESS
The AREA’S RICHNESS hile there is little doubt that the Coral Triangle is the richest marine environment on the planet, the reasons for the richness are hotly debated. Is it because Wthe richest taxonomic groups originated in the Coral Triangle and dispersed to the rest of the world? Or is it because of the overlap of flora and fauna from the West Pacific Ocean and Indian Ocean? As it turns out, the only thing that is clear is that the reasons for the area’s richness are complex and no single model explains it all. Some of the many factors that influence the diversity of the Coral Triangle are the geological history of the region, including plate tectonics and sea-level fluctuations; how species disperse and the factors that facilitate or inhibit dispersal; general biogeographic patterns and evolutionary forces. The tropics are generally more species rich than temperate and polar areas particularly because of the constant sunlight regime and weather stability. Without a winter period, organisms can flourish year round and put more energy into specialization than into preparing for long periods with reduced sunlight. This is as true in the marine realm as it is in the forests, where light and relatively constant warm water temperatures persist throughout the year. However, coastal tropical waters are relatively nutrient poor. The annual changes in water temperatures of the temperate and polar seas produce mixing when the surface waters cool and sink to the bottom. The displaced bottom waters, rich with dead plankton that has sank to the depths, are forced to the surface and result in Due to ocean circulation patterns and the rotation of the Earth, As the glaciers melted and sea levels rose, the newly evolved species huge explosions of zooplankton and fish populations. -
SEDIMENTARY FRAMEWORK of Lmainland FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA
GREAT BARRIER REEF MARINE PARK AUTHORITY TECHNICAL MEMORANDUM GBRMPA-TM-14 SEDIMENTARY FRAMEWORK OF lMAINLAND FRINGING REEF DEVELOPMENT, CAPE TRIBULATION AREA D.P. JOHNSON and RM.CARTER Department of Geology James Cook University of North Queensland Townsville, Q 4811, Australia DATE November, 1987 SUMMARY Mainland fringing reefs with a diverse coral fauna have developed in the Cape Tribulation area primarily upon coastal sedi- ment bodies such as beach shoals and creek mouth bars. Growth on steep rocky headlands is minor. The reefs have exten- sive sandy beaches to landward, and an irregular outer margin. Typically there is a raised platform of dead nef along the outer edge of the reef, and dead coral columns lie buried under the reef flat. Live coral growth is restricted to the outer reef slope. Seaward of the reefs is a narrow wedge of muddy, terrigenous sediment, which thins offshore. Beach, reef and inner shelf sediments all contain 50% terrigenous material, indicating the reefs have always grown under conditions of heavy terrigenous influx. The relatively shallow lower limit of coral growth (ca 6m below ADD) is typical of reef growth in turbid waters, where decreased light levels inhibit coral growth. Radiocarbon dating of material from surveyed sites confirms the age of the fossil coral columns as 33304110 ybp, indicating that they grew during the late postglacial sea-level high (ca 5500-6500 ybp). The former thriving reef-flat was killed by a post-5500 ybp sea-level fall of ca 1 m. Although this study has not assessed the community structure of the fringing reefs, nor whether changes are presently occur- ring, it is clear the corals present today on the fore-reef slope have always lived under heavy terrigenous influence, and that the fossil reef-flat can be explained as due to the mid-Holocene fall in sea-level. -

Recommended reading: Coral Reefs and Climate Change - Patterns of distribution (p.84-85) Zones across the reef (p.92-94) FRINGING REEF Fringing reefs are reefs that grow directly from a shore, with no “true” lagoon (i.e., deep water channel) between the reef and the nearby land. Without an intervening lagoon to effectively buffer freshwater runoff, pollution, and sedimentation, fringing reefs tend to particularly sensitive to these forms of human impact.

PLATFORM REEFS AND CORAL CAYS Platform reefs begin to form on underwater mountains or other rock-hard outcrops between the shore and a barrier reef. Coral cays begin to form when broken coral and sand wash onto these flats; cays can also form on shallow reefs around atolls.

Key agents in this shaping have been the calcium carbonate-fixing biota that have constructed the ocean- facing fringing reefs and produced the extensive backreef sediments that form the limestone platforms, cliffs and terraces that characterise these coasts. Today’s reefs comprise tough, algal- clad intertidal bars composed largely of coral rubble derived from their ocean front. They provide protection from wave attack to the inshore platforms with their sediment veneers and their beach and beach plain sands that are susceptible to erosion. If the eastern African coasts are subjected to the rise of sea-level that is predicted at the global scale during the coming century, the protective role of the reef bars will be diminished if their upward growth fails to keep pace. Favourable ocean temperatures and restraint in the destructive human pressures impacting the reef ecosystems will facilitate such growth. INTRODUCTION limestones).
