GEBCO’s gridded bathymetric data set, the GEBCO_2020 grid, is a global terrain model for ocean and land at 15 arc-second intervals. It is accompanied by a Type Identifier (TID) Grid that gives information on the types of source data that the GEBCO_2020 Grid is based.
If the data sets are used in a presentation or publication then we ask that you acknowledge the source.This should be of the form: GEBCO Compilation Group (2020) GEBCO 2020 Grid (doi:10.5285/a29c5465-b138-234d-e053-6c86abc040b9)
This is the report for the Reefs at Risk Revisited analysis. Reefs at Risk Revisited is a high-resolution update of the original global analysis, Reefs at Risk: A Map-Based Indicator of Threats to the World’s Coral Reefs. Reefs at Risk Revisited uses a global map of coral reefs at 500-m resolution, which is 64 times more detailed than the 4-km resolution map used in the 1998 analysis, and benefits from improvements in many global data sets used to evaluate threats to reefs (most threat data are at 1 km resolution, which is 16 times more detailed than those used in the 1998 analysis).
This fragility assessment of South Tarawa in Kiribati explores patterns of fragility related to urban development including delivery of critical urban services with focus on water and sanitation services. The assessment’s key objectives are to determine and better understand the patterns of fragility and resilience created by state–society relationships, as they relate to the delivery of urban services in South Tarawa, and to identify means of overcoming fragility to improve the quality of urban life in the community.
The objective of the participatory consultations with stakeholders in Bikenibeu West was to identify possible solutions to address root causes of waste problems threatening fresh and marine water quality.

The objective of this study is to determine the available coconut resources in the Line group and analyse the technical, economic, social, institutional, environmental feasibility of producing coconut oil on Kiritmati Island and use it as a fuel substitute in power generation and transport .
This study compared parasite communities at two coral atolls in the Line Islands chain of the central Pacific (Kiritimati Island and Palmyra Atoll). Palmyra Atoll is relatively pristine while Kiritimati Island is heavily fished. At each island, the study sampled five fish species for helminth and arthropod endoparasites: Chromis margaritifer, Plectroglyphidodon dickii, Paracirrhites arcatus, Acanthurus nigricans, and Lutjanus bohar. The surveys found monogeneans, digeneans, cestodes, nematodes, acanthocephalans, and copepods.
Effective conservation requires rigorous baselines of pristine conditions to assess the impacts of human activities and to valuate the efficacy of management. The study found that top predators and reef-building organisms dominated unpopulated Kingman and Palmyra, while small planktivorous fishes and fleshy algae dominated the populated atolls of Tabuaeran and Kiritimati.
This paper is a compilation and analysis of all vascular plants that have been reported on Kiritimati (Christmas) Atoll in the Northern Line Islands of the Republic of Kiribati. It is based on field inventories
conducted by the authors on six field visits to the atoll between 1996 and 2012 plus available published
and unpublished records of vascular plant collections and observations made on the atoll.
Two soils investigations were investigated in the 1960s, but no additional information on the soil resource of the island has been produced since that time. In this study, 15 soil types were described and analyzed. Where possible, comparison has been made with previous works.
