The World's oceans play a crucial role for life on the planet.
Healthy seas and the services they provide are key to the future
development of mankind. Our seas are highly dynamic, structured and complex systems. The seafloor consists of vast shelves
and plains with huge mountains, canyons and trenches which
dwarf similar structures on land. Ocean currents transport water
masses many times larger than all rivers on Earth combined.

GOOS is being implemented in the Pacific islands region by PacificGOOS, which was formed in Suva in 1998. In August 2000, in Apia, Samoa, PacificGOOS held a regional workshop on the development of a coastal Global Ocean Observing System (GOOS) for the Pacific region. This workshop aimed to raise the level of awareness about PacificGOOS and its value for sustainable
Microbenthos and macrobenthos were quantitatively studied at 62 stations distributed regularly over the Uvea Atoll lagoon (850 km2). Sampling was performed using both SCUBA and a 0.1 m2 Smith Mclntyre grab. Mean estimates of ATP, chlorophyll a and phaeopigments were 297.3ng/cm2, 77.01 mg/m2 and 35.28 mg/m2
respectively. The mean macrobenthic biomass was 4.14 gAFDW/m2 of which the macrophytobenthos accounts for 39%. The benthic biomass decreased from the coast to the deepest parts of the lagoon. Macrophytes were most abundant in the coastal area
What are the decapod crustacea known from French Polynesia? The answer to this, apparently simple question, would be very helpful for determinating the species collected during ecological studies. Moreover, from a biogeographical point of view, a check list of the species reaching this area, at the eastern limit of the Indo-West Pacific province, would be very interesting.
Fish communities in the lagoon of the Tikehau atoll were studied by only a few researchers. Harmelin-Vivien (1984) studied the distribution of the main herbivorous families (Scaridae and Acanthuridae) in the lagoon and on the outer slope to 30 m in depth. The total fish community of the outer slope was studied by Galzin (1985, 1987) at 12 m in depth. These studies were carried out in the southwestern part of the atoll. Spatial organization of coral associated fish community was studied throughout the lagoon by Morize et al. (1990). Most of the other
The colonization of the lagoon by coral reef fish larvae was compared between two islands of French Polynesia, the atoll of Rangiroa and the high volcanic island of Moorea. In both cases the larval flux coming into the lagoon followed a daily cycle.
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.
Recent studies have shown that many coral reefs are capable of
yielding a total fish catch of 18- 24 T.Km-2 (Hill, 1978; Alcala,
1981; Munro, 1987). There are, however, no estimates for the
productivity and yield of fishes associated with coral reefs in
French Polynesia. This study was designed to determine the fisheries yield from a part of the fringing reef on the island of Moorea, French Polynesia.

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.
Reef coral collections from American Samoa are in the National Museum of Natural History, Smithsonian Institution, Washington, D.C., and in the Hessisches Landesmuseum, Darmstadt, W. Germany. The author has a collection of 790 coral specimens for a total of 1547 items known to be from American Samoa.
A total of 177 species (including 3 species of non-scleractinian corals) belonging to 48 genera and subgenera (including the genera Millepora and Heliopora) known to date are listed with data as of frequency of occurrence and habitat.

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.

Tongatapu, like Tahiti, was visited by many early
European navigators and was one of the first of the South
Pacific islands to be charted in any detail. Though it was
discovered (and named Amsterdam Island) by Tasman in
January 1643 (Sharp 1968, 152-158), the first comments on
the sand cays of the surrounding reefs were made by Cook
during his second voyage, with the Resolution and Adventure,
in October 1773. On this occasion Cook spent less than a
week at Tongatapu, anchored in the northwest, and commented
Coral reefs are vital ecosystems, providing a source of income, food arid coastal protection for millions of people; arid recent studies have shown that coral reef goods and services provide an annual net benefit of US$30 billion to economies worldwide
During the period February 13 to 20, 1973, a visit was made to Canton Island for the purpose of conducting a preliminary survey of marine turtle nesting populations. Although previous investigators have described the sea birds (Buddle, 1938; Murphy G., 1954), insects (Van Zwaluwenburg, 1943, 1955), and vegetation (Hatheway, 1955), very little is known about the marine environment of Canton or the other seven atolls (Enderbury, Birnie, Phoenix, Sydney, Hull, Gardner and McKean) which comprise the Phoenix group.
The Gilbert Islands are a part of the Gilbert and Ellice Islands Crown Colony of Great Britain. They lie in the Pacific Ocean directly southeast of the Ilarshall Islands and are located between the parallels of g045' S. and 3'30' N. latitude, and the meridians of 1720301 E. and 177 15' E. longitude. All of the islands in this groui3 are low islands related to atolls. They are inhabited by Micronesian and Melanesian people who are greatly dependent on materials from the sea for food.

Helen Reef in the Southwest Islands of Palau is the one of the greatest marine assets of the Hatohobei (Tobi) People and of the Republic of Palau. Helen Reef is known as one of the most biologically diverse coral reef atolls in the Pacific and historically one of the most biologically abundant reefs in Palau,including acclaimed populations of plentiful marine resources including, trochus, turtles, sea cucumbers, seabirds, and many large reef fish.
