raw rainfall data collected in 2016

Tables 14 cross-tabulates different socio-demographic and economic variables by damage (household + other dwelling). The table suggests that the worse-off were more affected by GITA.

Spreadsheet and graph derived from table 1 of Kingdom of Tonga National Plan of Action (NPOA) Shark-Plan (2014-216)

Time series data and graph of Tonga's deepwater fishery total catch 2006-2016.

Most atoll ecosystems and a wide range of terrestrial and marine organisms, and genetic or cultivars varieties of
traditional food and other multi-purpose plants are declining in abundance and under threat of either “economic extinction” or extirpation and in need of some form of protection. The severity of the situation is greatest on those more urbanized atolls where both the biodiversity and the local knowledge of biodiversity are threatened.

Terrestrial and marine plants and animals that are rare, endangered or in short supply,
and in need of protection in the atolls of the Pacific Islands.

This excel file include four spreadsheets each representing a separate theme (EMG = Environmental Monitoring and Governance, IOE = Island and Ocean Ecosystems, CCR = Climate Change Resilience, WMPC = waste). Within each theme are the core national environment indicators (scrolling from left to right).

Bio-ORACLE is a set of GIS rasters providing geophysical, biotic and environmental data for surface and benthic marine realms. The data are available for global-scale applications at a spatial resolution of 5 arcmin (approximately 9.2 km at the equator).

Linking biodiversity occurrence data to the physical and biotic environment provides a framework to formulate hypotheses about the ecological processes governing spatial and temporal patterns in biodiversity, which can be useful for marine ecosystem management and conservation.

Raster data representing the mean levels of calcite in µmol/m3 for the surface water layer. The data are available for global-scale applications at a spatial resolution of 5 arcmin (approximately 9.2 km at the equator).

Marine data layers for present conditions were produced with climate data describing monthly averages for the period 2000–2014, obtained from pre-processed global ocean re-analyses combining satellite and in situ observations at regular two- and three-dimensional spatial grids.

Raster data representing the mean levels of current velocities in meters/second for the surface water layer. The data are available for global-scale applications at a spatial resolution of 5 arcmin (approximately 9.2 km at the equator).

Raster data representing the mean levels of pH for the surface water layer. The data are available for global-scale applications at a spatial resolution of 5 arcmin (approximately 9.2 km at the equator).

Raster data representing the mean levels of photosynthetically active radiation (PAR) in E/m2/year for the surface water layer. The data are available for global-scale applications at a spatial resolution of 5 arcmin (approximately 9.2 km at the equator).

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).

Metadata file for the GIS data (raster and shapefiles) for the global threats to coral reefs: acidification, future thermal stress, integrated future threats, and past thermal stress.

Metadata file for the GIS data (raster and shapefiles) for the local threats to coral reefs: coastal development, integrated local, marine pollution, overfishing, and watershed pollution.
