Shoreline Changes and Sediment Redistribution at Palmyra Atoll (Equatorial Pacific Ocean): 1874–Present

  title={Shoreline Changes and Sediment Redistribution at Palmyra Atoll (Equatorial Pacific Ocean): 1874–Present},
  author={John D. Collen and David W. Garton and Jonathan P. A. Gardner},
Abstract Reef islands of Palmyra Atoll in the northern Line Islands, equatorial Pacific Ocean, underwent mainly minor natural changes in shape and size between 1874 and 1940. Many major changes occurred between 1940 and 1945 when military construction created a dredged channel into the lagoon, enlarged several islands, joined most islands around the lagoon system into a continuous roadway, constructed a causeway separating two lagoons, and created several new islands. Overall, land area…

Coral atolls are unique landforms in that they are the physical manifestations of the interplay between both biological and geological processes. Prominent amongst these processes is the ability of

Shoreline Changes on an Urban Atoll in the Central Pacific Ocean: Majuro Atoll, Marshall Islands

Abstract FORD, M., 2012. Shoreline changes on an urban atoll in the central Pacific Ocean: Majuro atoll, Marshall Islands. Majuro is the capital and most populated atoll in the Republic of the

Nature and stability of atoll island shorelines: Gilbert Island chain, Kiribati, equatorial Pacific

Islands rimming Pacific atolls typically form narrow, low‐lying lands that are commonly perceived to be particularly vulnerable to global changes such as sea‐level rise. As these, low islands form

Destruction or persistence of coral atoll islands in the face of 20th and 21st century sea‐level rise?

The future of low‐lying reef islands has been the subject of international concern, scientific debate, and media interest in the last decade. As a result of sea‐level rise, atoll islands are expected

Over the past decades, atoll islands exhibited no widespread sign of physical destabilization in the face of sea‐level rise. A reanalysis of available data, which cover 30 Pacific and Indian Ocean

Carbonate Beach Sand of Abaiang Atoll, Kiribati: Geochemistry, Biogenic Sources, and Properties

Sandy beaches are critical resources for low-lying Pacific atoll communities, providing protection during storms, and land area for many coastal villages. Information on the nature of atoll beach

Assessing Long-Term Changes in the Beach Width of Reef Islands Based on Temporally Fragmented Remote Sensing Data

The results show that remote imagery with a low sampling frequency may be sufficient to characterize prominent morphological changes in planform beach configuration of reef islands, and suggest that changes in beach width on Taku Atoll are dependent on local control.



Response of reef island shorelines to seasonal climate oscillations: South Maalhosmadulu atoll, Maldives

[1] The Maldives experience seasonal shifts in monsoon winds from the west-northwest to northeast. The morphologic response of reef island beaches and shorelines to these predictable shifts in

Holocene Sea-Level Record on Funafuti and Potential Impact of Global Warming on Central Pacific Atolls

Abstract Geomorphic features inherited from the mid-Holocene glacio-hydro-isostatic sea-level highstand that affected the central Pacific region influence the susceptibility of atoll islets to

Coastal Erosion and Management of Majuro Atoll, Marshall Islands

About fifty kilometers of lagoon coast in Majuro Atoll is suffering erosion, which is induced by human activities including aggregate excavating and building causeways, artificial channels, landfill

New model of reef-island evolution: Maldives, Indian Ocean

A new model of reef-island evolution, based on detailed morphostratigraphic analysis and radiometric dating of three islands in South Maalhosmadulu Atoll, Maldives, is presented. Islands initially

Climatic Change and the Future of Atoll States

The combination of rising sea level and increased storminess that is expected to accompany changes in global climate due to the greenhouse effect may well have severe impacts on low lying coral
