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.
During the period 1958-1964, the authors undertook soil and vegetation studies in the northern Marshall Islands as part of the University of Washington Radiation Biology Laboratory surveillance team. This team was responsible for monitoring levels of radiation in various components of the island environment and any effects on plant and animal life. The authors of this report were charged with the soils and vegetation components but assisted with collections in the aquatic ecosystems and some food plant materials.
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,
This monograph sheds light on the status of secondary plant cover, heretofore little known, on slopes between sea level and about 750m in the Marquesas Islands, a remote tropical Polynesian archipelago of high islands of volcanic origin situated in the dry tradewind zone of the South Pacific. Plant cover types are described and assigned to xerotropical, transitional and pluviotropical floristic zones determined in part by comparison with similar zones previously devised for Oahu Island, Hawaii.

Mauke, Mitiaro and Atiu are deeply eroded volcanic islands in the southern Cook Islands, south Pacific, each surrounded by a rim of elevated Cenozoic reef limestone (makatea). This paper presents the results of instrumental topographic surveys of each
This review was prepared on very short notice, to
provide a summary of what is known to the reviewer at the
time, June 1988, about the natural phenomena of the Marshall
Islands. This was for the use of the members of the survay
team sent to the Marshalls by the Environment and Policy
Institute of the East-West Center, Honolulu. Their mission
was to investigate the remaining relatively natural areas
and the extent of biodiversity in the new Republic of the
Marshall Islands.

Interpretation of SEASAT geoid anomaly data and improved seafloor mapping of the
south-central Pacific suggest a complex tectonic history for the islands of the Pitcairn
group. While Oeno atoll formed at ~ 16m.y.BP at a 'hotspot' now south of the Easter micro-
plate, subsequent progressive island development at Henderson (13m.y.), Ducie (8m.y.)
and Crough seamount (4m.y.) resulted from the lateral leakage of magma from the Oeno
lineation along an old fracture zone, itself originating during the Tertiary reorientation
Field work conducted by the senior author at Bikini
Atoll, Marshall Islands, in May 1986 yielded twenty-three
species of birds; six of these were documented as nesting
and an additional four species almost certainly nest as
well. Six species were previously unrecorded for Bikini
Atoll, and one of these, the Laughing Gull (Larus
atricilla) was new to Micronesia. The recorded avifauna
for Bikini Atoll now stands at twenty-six species. Major
seabird colonies were located on Aomoen (and other
The islands of the southern Cook and Austral groups in
the South Pacific exhibit astonishing differences in geology
and topography, even between closely adjacent islands of
similar ages. Some are sea-level atolls, others have low
fringes of Pleistocene raised reefs, and others substantial
rims of elevated mid-Tertiary limestones, locally known as
makatea. On some islands the relief of the makatea is
subdued, but on others it is dominated by eroded volcanics,
sea-level swamps, and vertical limestone walls. Sixty years
Located at 148°15' West and 15°50' South, in the northwesternmost part of the Tuamotu archipelago (Central Pacific), Makatea island is isolated from its nearest
neighbouring atolls, Rangiroa and Tikehau by about 80 km, and it is 245 km from its closest volcanic neighbour, Tahiti. This island rises at least 3,500 m above the sea floor.
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.
As of 1969, the scientific community had no general information on the natural history of Namoluk Atoll in the Eastern Caroline Islands of Micronesia. The only significant published source for the atoll was an ethnographic and linguistic account provided by the German physician.
Interface habitats, areas where aquatic and terrestrial habitats intersect, play important functional roles. Interface habitats mediate the exchange of resources (e.g.. energy,
nutrients, water), alter abiotic gradients (e.g.. temperature, salinity, pH. sedimentation, nutrients), insulate abutting habitats from disturbances, and serve as critical habitat in
The Main Species Of holothurian exploited in the Sputh Pacific are Holothuria scabra, H. Fuscogilva And H. nobilis, which have high commercial value , Actinopyga echinites, A. Miliaries And Thelenota ananas Of medium commercial value, And Holothuria atra, H. fuscopunctata and H. mauritiana, whose commercial value is low.

Satawal is a small flat coral island in the west central Caroline Islands about 1050 km east-south-east of Yap Island, at latitude 7'21' N, longitude 147'02' E. Although its surface is locally somewhat irregular, its greatest height is not more than about 4 meters above mean low water. Its long axis is about east-west and its area is 1.3 square km. It is surrounded by a fringing reef upward of 100 meters wide. It has no lagoon, so would be classified according to Tayama's scheme as a table reef. From the viewpoint of land ecology it is an atoll.
Rangiroa is the largest atoll in the Tuamotu Archipelago, and since the institution of a regular air service, the most accessible; yet in common with other Tuamotuan atolls it has rarely been visited by scientists and is barely mentioned in the literature. Dana (1849) published brief notes following the Wilkes Expedition; but the only full account is that by Agassiz (1903). Agassiz's descriptions are, however, verbose and imprecise, and marred by misinterpretations of major atoll features.
During October and November of 1961, the Marine Physical Laboratory of the Scripps Institution of Oceanography, in cooperation with the British Atomic Weapons Research Establishment, sponsored a series of geophysical measurements on Christmas Island. Continuous recordings of the earth's magnetic field were made simultaneously at various points on the island under the direction of Ronald G. Mason and John Northrop of the Marine Physical Laboratory of the University of California, San Diego.
This report has benefited from the inputs of hundreds of individuals, a list far too numerous to include in its entirety. These individuals volunteered their time to support this effort, and to that we are deeply indebted. We want to thank them all knowing full well that this task is not feasible..

Reef fish assemblages were monitored annually from 1978 to 1981 at a series of stations adjacent to an airport runway construction site on Moen, Truk. Monitoring began prior to construction activities and continued through three years during which dredging and filling of adjacent reef areas took place. As a result of construction activities, large amounts of sediments were released into the water. Turbidity was measured monthly
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
