The management and conservation of the world's oceans require synthesis of spatial data on the distribution and intensity of human activities and the overlap of their impacts on marine ecosystems. We developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine(More)
Very little is known about how environmental changes such as increasing temperature affect disease dynamics in the ocean, especially at large spatial scales. We asked whether the frequency of warm temperature anomalies is positively related to the frequency of coral disease across 1,500 km of Australia's Great Barrier Reef. We used a new high-resolution(More)
Spatially intimate symbioses, such as those between scleractinian corals and unicellular algae belonging to the genus Symbiodinium, can potentially adapt to changes in the environment by altering the taxonomic composition of their endosymbiont communities. We quantified the spatial relationship between the cumulative frequency of thermal stress anomalies(More)
1. ABSTRACT There are many challenges in blending historical and modern observations of sea surface temperature (SST) into homogenous gridded data sets suitable for use in climate research. Many of these problems can be avoided if proper choices are made during design and deployment phases of new instrumentation and observing systems, as specified in the(More)
Human pressures on the ocean are thought to be increasing globally, yet we know little about their patterns of cumulative change, which pressures are most responsible for change, and which places are experiencing the greatest increases. Managers and policymakers require such information to make strategic decisions and monitor progress towards management(More)
Executive Summary This paper provides a core contribution to address the OceanObs09 theme " Developing technology and infrastructure " under Session 4B " Satellite data integration and products ". It has been prepared for those implementing and working with the modern sea surface temperature (SST) observing system. The purpose of the paper is threefold: (1)(More)
