Pre-Mining Pattern of Soils on Nauru, Central Pacific

  title={Pre-Mining Pattern of Soils on Nauru, Central Pacific},
  author={R. John Morrison and Harley I. Manner},
ABSTRACT The environment of Nauru, a raised atoll located in the central Pacific Ocean (0° 32′ S, 166° 56′ W), was devastated by mining of phosphate “rock” during the twentieth century. [] Key Result Four major soil associations were identified: the coastal fringe carbonate dominated soils set on a recent fringing reef; deep and relatively deep phosphate-dominated soils free of substantial influence from the underlying dolomite pinnacles occurring on the NE, NW, SE, and SW sectors of the uplifted section of…

The mined-out phosphate lands of Nauru, equatorial western Pacific

ABSTRACT Nauru once possessed the world's purest deposits of rock phosphate, the precursor of the agricultural fertiliser, superphosphate. This resource was almost entirely depleted during the 20th

Regional assessment of soil change in the Southwest Pacific

The Southwest Pacific region includes the 22 island nations of the Pacific1, New Zealand and Australia (Figure 15.1). The landscapes of the region are very diverse ranging from a large continental

Saltwater Intrusion and Freshwater Storage in Sand Sediments along the Coastline: Hydrogeological Investigations and Groundwater Modeling of Nauru Island

Water resources sustainable management is a vital issue for small islands where groundwater is often the only available water resource. Nauru is an isolated and uplifted limestone atoll island

The Soils of Kiritimati (Christmas) Island, Kiribati, Central Pacific: New Information and Comparison with Previous Studies 1

Abstract: Kiritimati, the largest land area atoll in the world, is undergoing rapid population increase, and, given the isolation of the island, local food production will have to be expanded to

Characteristics of Coral Cay Soils at Coringa-Herald Coral Sea Islands, Australia

Mining, land restoration and sustainable development in isolated islands: An industrial ecology perspective on extractive transitions on Nauru

A holistic approach is offered that considers prudent use of Nauru’s remaining mineral resources towards an agenda of ecological restoration and economic diversification that will allow the island to prosper after the phosphates it has traditionally relied upon are depleted.

Restoring the Soils of Nauru: Plants as Tools for Ecological Recovery

The restoration of Nauru’s mined areas is fundamental to the future wellbeing of the people and ecosystems of Nauru. Extensive open cast phosphate mining on Nauru over the last 100 years has led to

The Reptiles of Nauru1

ABSTRACT Eleven species of reptiles are reported from Nauru in the first systematic treatment of the herpetofauna. Four of the species are marine; the seven others include six lizards (four geckos,

Phosphate Mining Induced Vegetation Changes on Nauru Island

Postmining succession and pre-mining forest vegetation were studied on the isolated, tropical, central-Pacific, phosphate-rich island of Nauru. An analysis was made of the extent to which natural

A Temporal Sequence (Chronosequence) of Soil Carbon and Nitrogen Development after Phosphate Mining on Nauru Island

Ten composite soil samples (0-15 em depth) were collected from abandoned phosphate-mined sites on Nauru Island (Central Pacific) and analyzed for % organic C and % N. The samples represent a temporal

Structure and evolution of Nauru Island, central Pacific Ocean

Nauru Island, in the central Pacific Ocean, is a raised atoll capping a volcanic seamount rising from an ocean floor depth of 4300 m. The land area is 22 km2, and the island rises to 70 m above sea

I. Introduction Within the tropical belt of the Pacific Ocean occur several islands containing deposits rich in calcium phosphate. The majority of these islands are situated within 10° of the

Vegetation of Nauru and the Gilbert Islands: Case studies of poverty, degradation, disturbance, and displacement

The indigenous floras of the raised phosphatic limestone island of Nauru and the atolls of the Gilbert Islands are among the poorest on earth. Long settlement, widespread destruction during World War

Plant succession after phosphate mining on Nauru

Summary Since 1907 phosphate mining and other forms of human‐induced disturbance have severely modified Nauru's topography and vegetation. Through a series of 10 m × 10 m quadrats in mined and

The effect of superphosphate on the cadmium content of soils and plants

The cadmium content of phosphatic fertilizers manufactured in New South Wales ranged from 18 to 91 p.p.m. and was closely correlated with phosphorus content. Superphosphate contained 38-48 p.p.m.

Changes in the forms of cadmium with time in some Western Australian soils

Changes in the forms of Cd with time could affect its uptake by plants and hence potential toxicity to animals and humans. The effect of time on the forms of native and added Cd was studied in four
