A mission to increase our understanding of climate change and its impact on coral reef ecosystems in the Western Pacific Warm Pool.
Mission Overview
Approach & Findings
Data Collected
This expedition also provided the opportunity to investigate coral reef ecology and coral health in relatively remote and pristine regions across Micronesia. This research is essential, given that corals around the world are declining due to local environmental degradation and large-scale climate change. The team collected coral reef survey data, together with coral tissues and water samples, from across a broad area with gradients of island size and human population. Diversity and abundance of coral communities appear to reflect population density on the islands, possibly due to local fishing pressure on herbivorous fish. Analysis of the microbial and molecular lipid composition of coral tissues provides insight into the functioning of the coral symbiont system in both healthy and stressed (diseased or bleached) samples. During the expedition, coral reef ecological surveys revealed the first instance of cyanobacterial infection of crustose coralline algae, and documented the new expansion of the range of White Plague Disease into the western equatorial Pacific.
