South East Asia and Melanesia contains the largest deposits of nickel lateritic ores.

Environmental impacts may occur if mining operations are not adequately managed.

Risk assessment tools for nickel in the tropics are limited due to lack of data.

We compiled nickel data for aquatic tropical ecosystems and identified key gaps.

Nickel data is required for corals, molluscs, crustaceans, echinoderms, macroalgae, fish.
