Rarotonga and Aitutaki form the summits of separate
volcanic masses rising from depths of 4000 m, at which depth
the cones are 45-55 km in diameter (Summerhayes and Kibblewh
1966, 1967).The lower slopes of the cones average 15-25
increasing to 30 in the upper 750 m and becoming very steep
the surface reef is approached. The Mauke-Aitutaki line of
islands is thought to be of early Tertiary age: the surface
volcanics are much eroded, with a subdued topography, or are
capped with limestones (Wood, 1967; Wood and Hay, 1970). On
This paper describes the channels known as hoa which are characteristic of atoll land rims and of some islands on barrier reefs, where they often dissect previously more continuous reef-top sediment accumulations and conglomerate platforms. They are
Nukutipipi atoll (5 km2), of volcanic origin 16-17 million years old on the Pitcairn (hot spot) Hereheretue line, presents a land flora and fauna of low diversity but with a Pisonia forest and hundreds of resident red-tailed tropic birds. Nukutipipi suffered from the 1983 hurricanes : destruction of vegetation and motu as well as sand lagoon mollusc populations. The north and south rims present original geomorphological structures.
Jonathan Sauer (1961) remarked, in his Coastal Plant Geography of Mauritius, that the chance to study the coastal vegetation there was like being "admitted to a field worker's paradise"
and stressed that "most tropical coasts are beautiful and exciting, particularly to people concerned with natural processes . . .." The same can certainly be said for the tropical coasts of the often Edenized islands of the Pacific Ocean. Their "beauty and excitement" is considerably enhanced,
Coral atolls are natural laboratories within which to examine ecological processes (Sachet, 1967; Lee, 1984). They are often isolated, in some cases little disturbed, and have a geologically recent history of terrestrial plant colonisation. Reef islands around the rim of most atolls are Holocene in age. They are composed of biogenic skeletal sediments and have developed since reef growth caught up with sea level which stabilized after post-glacial sea-level rise. Plant colonisation of most of these islands must have occurred over a period of no more than 6000 years.
In a typical High Island coral reef complex of French Polynesia (transect of Tiahura, Hoorea Island, Society Archipelago!, 73 species of decapod Reptantia and stomatopod crustaceans were collected. Over 9 stations localised along the transect, 3 different units of hard coral substrate of simi1ar volume (about 17 litres each), were sampled at each station. The results are discussed from two aspects : the first shows that at least 50 carcinologic species occur within the cavitary biotopes ; 16 species (mainly Xanthid crabs), represent more than 90% of all collected individuals.
The conservation status, ecology, and cultural importance of sea turtles at the three Polynesian atolls of Tokelau are presented. The green turtle, Chelonia mydas. is the most common species, occurring as a migrant breeder mostly during September through November. The hawks- bill, Eretmochelvs imbricata. is present in small numbers at all three atolls, but nesting is only known at Nukunonu Atoll. A third species, the loggerhead, Caretta caretta. has also been recorded on rare occasions.
The Tokelau Islands consist of three atolls (Atafu, Nukunonu and Fakaofo) approximately 500 km north of Western Samoa. Their numerous islets are formed mainly of coral sand and rubble with no standing freshwater. Sixty-one plant species have been recorded, 13 of these being introduced and 10 being adventives. There are three vegetation zones, the beach, the beach-crest, and the interior coconut/fern zone with the physiognomy of a humid tropical forest. Marine invertebrates have not been studied.
Species-numbers relationships in the McKean Island assemblage
of reef-building corals were investigated to discover how they changed along environmental gradients of the reef. For the purposes of the study, two gradients were identified a complex depth gradient and a wave exposure gradient.

It has been over twenty years since UNCLOS came into existence and twelve years since it came into force, in addition to fourteen years since the historic "Earth Summit" was convened in Rio de Janeiro in Brazil, yet the Pacific Small Island Developing States (SIDS) are finding it extremely difficult to deal with many cross-cutting and multiple issues relating to ocean management. The challenge for the Pacific SIDS is clear, successive international, regional and national initiatives
This report lias been prepared on behalf of the Environment Service, Cook Islands as part of an ongoing monitoring programme of reef health of the fringing reef of Rarotonga. The
initial work was earned out in 2000 and this is the first subsequent sampling and report since that baseline study.

Information currently available from Solomon Islands on blacklip pearl oysters(Pinctada margaritifera) and their potential culture comes from three main sources; records of past exploitation, occasional resource surveys that have included blacklip pearl oysters; and research on culture of blacklip oysters in Solomon Islands. Statistics on past exploitation are limited to export tonnage and value collected by the Statistics
The main goal of the project is to improve the planning and management of coastal resources in Fiji using an integrated approach, with the Coral Coast of Nadroga Province serving as a pilot site. Integrated Coastal Management (ICM) is a process that involves the integration (working together) between sectors at both the local and national levels and also between different levels of government. ICM helps solve problems. This initiative worked at both levels.
The Fiji Islands are surrounded by numerous fringing coral reefs which are an extremely important natural resource, valuable as local fishery areas, tourist attractions, and for protection of the coastline from the damaging effects of waves. Over recent years, there has been increased development of the coastline in Fiji which has lead to pressure on the surrounding reefs. Degradation of reefs has been observed as the result of factors such as increased erosion on land and siltation of reefs, water
Solomon Islands is one of the seven countries of the South West Pacific Node of the Global Coral Reef Monitoring Network (GCRMN). The country coordination is carried out by the World Wild Fund for Nature (WWF) Gizo Office in the Western Province. All coral reef monitoring activities are carried out by WWF Gizo staff with very little interaction with other stakeholders in way of information sharing.

In 2000, the Fiji Islands was at the northern edge of a large pool of unusually warm water, and suffered extensive hard coral death due to coral bleaching. A paper composed of a collection of studies from across the Fiji islands, linking this coral
death to elevated sea temperatures at the time, was published (Cummings et al 2000). The difficulty of gathering data from very different sources, and which had been recorded using many different methods, established the need for standardised
Sea temperatures in many tropical regions have increased by almost 1°C over the past 100 years and are currently increasing at 1 ~ 2°C per century. Satellite and compiled in situ observations of sea surface temperatures have greatly increased the ability to detect anomalous and persistent warm water and are being widely used to predict climate change, coral bleaching and mortality.
Capacity building in the marine sector is a priority for Pacific Island nations, which face major challenges in the sustainable management of their marine resources under UNCLOS III and the various Conventions and Agreements stemming from UNCED. The University of the South Pacific (USP), with its 12 Pacific Island members (Cook Islands, Fiji, Kiribati, Marshall Islands, Nauru, Niue, Samoa, Solomon Islands, Tokelau, Tonga, Tuvalu, Vanuatu) has taken up this challenge through the establishment of its Marine Studies Programme (MSP) in 1993.
The Pacific Islands region is important for a great number of cetaceans (whales and dolphins), whether as a permanent habitat, a breeding ground or a migration corridor. Currently, more
than thirty species of whales and dolphins have been identified in this area.
The presence and diversity of cetaceans in our region has led to the development of whale watching, both on a commercial and recreational basis. Whale watching is defined as viewing
The Ministry of Agriculture, Quarantine, Forestry and Fisheries (MAQFF) is mandated to manage resources that are vital to the well-being of Vanuatu people and the economy. The structure of the Ministry is shown in Attachment 1. Government is mindful that where there are no sustainable management practices, resources are overexploited and much to the disadvantage of local communities and the environment. This is witnessed the world over and is becoming evident with some resources in the islands of Vanuatu.
