dataset with internet direct links and resources relating to the global seafloor geomorphic features that represents an important contribution towards the understanding of the distribution of blue habitats. Certain geomorphic feature are known to be good surrogates for biodiversity. For example, seamounts support a different suite of species to abyssal plains.
Physical geography, biological, bathymetry, geomorphology, oceanography, uses, risks spatial data for Solomon Islands marine environment.
Maps showing geomorphic features. The maps were developed by MACBIO as resources for the bioregions workshops in Feb 2018.

An academic study on the geomorphic adjustment of Nadikdik Atoll based on the comparison of aerial photographs taken in 1945 and modern satellite imagery, after the devastating typhoon that over-washed and destroyed the atoll in 1905. This study has significant implications for the geomorphic understanding of reef islands, revealing magnitudes of island change not previously recognized.
The lagoon of Tarawa harbors the richest benthos documented for any Pacific atoll. The biota is strongly influenced by its setting in the equatorial upwelling zone and the unusual geomorphology of the atoll, with a submerged western rim, but largely closed and islet-strewn eastern and southern sides.
The purpose of this paper therefore is to describe aspects of the benthic ecology and biota of Tarawa Atoll and to consider how the unusual setting of the atoll has affected the bentho.
This report describes the high-resolution bathymetric mapping survey carried out in 2004. The survey achieved good coverage of the seafloor from approximately 10 m depth in the nearshore reef slope area, to an average offshore depth of some 2000 m, at an average slope angle of 2. The objective was to investigate the seabed and provide information about water depths around the islands using a multibeam echosounder (MBES).
