Several GIS file types illustrating Tongan Coral reef geomorphic structure
Data originally produced by Millennium Coral Reef Mapping Project validated maps provided by the Institute for Marine Remote Sensing, University of South Florida (IMaRS/USF) and Institut de Recherche pour le Développement (IRD, Centre de Nouméa), with support from NASA.

Spatial dataset with mangroves in Vanuatu. Source: Vanuatu Resource Information System (VANRIS).
This dataset contains all spatial data that is related to the Tonga volcanic eruption. Maps produced are derived from credible data source such as UNOSTAT and UNITAR.
This dataset the extent of coral reefs around Pohnpei. The data layer shown here is a subset of Pohnpei base layer. The original data, so-called Digital Line Graphs (DLSs), were created by U.S. Geological Survey (USGS) for the 1:25,000-scale topographic maps (2001). The shoreline was modified by by University of Guam (UOG) (2017) based on 2016 Worldview-3 satellite imagery from Digital Globe. The dataset was slightly shifted and also updated (mainly around Kolonia and its vicinity).
This dataset shows the extent and basic types of sea grass areas around Pohnpei. It classifies sea grass areas by one of the three main species (Cymodocea rotundata, Thalassia hemprichii, and Enhalus acaroides) and the level of coverage (describes as continuous, aggregated, and isolated). The data source is McKenzie, L.J. and Rasheed, M.J.

Fisheries in the Solomon Islands comprise two distinct sectors: the industrial sector which is predominantly off-shore and depends on the abundant tuna resources found in the country's
Species which have been assessed for extinction
risk are on average moving closer to extinction.
Amphibians face the greatest risk and
coral species are deteriorating most rapidly in
status. Nearly a quarter of plant species are estimated
to be threatened with extinction.
