2018 Marine Pollution Bulletin  
A B S T R A C T In Bunaken Island (Indonesia), a time-series of very high resolution (2-4 m) satellite imagery was used to draw the long-term dynamics of shallow reef flat habitats from 2001 to 2015.  ...  While trajectories of reef habitats is a way to measure resilience and coral recovery, here, the 15-year time-series was too short to be able to conclude on the resilience of Bunaken reefs.  ...  Acknowledgements This study was possible with the support of the INfrastructure DEvelopment of Space Oceanography (INDESO) project in Indonesia, and its Coral Reef Monitoring Application.  ...

Assessing and mapping of carbon in biomass and soil of mangrove forest and competing land uses in the Philippines

Jose Castillo, Armando Apan, Maraseni Tek
Overall, Sentinel-1 SAR and Sentinel-2 multispectral imagery can provide satisfactory results in the retrieval and predictive mapping of aboveground biomass in mangrove area.  ...  Overall, C losses in soil owing to land use conversion in mangrove ranged from 398 to 809 MgC ha -1 (mean: 486.8 MgC ha -1 ) or a decline of 57% in soil C stock, on average.  ...  However, the combination of multi-temporal VH and VV polarisations correlated better with biomass than single-date SAR imagery.  ...
