My research interests focus mainly around corals and coral reefs, both modern and ancient, and both tropical and temperate (deep-sea). Coral reefs are subject to a variety of stresses, including pollution, sedimentation, overfishing, and climate change. My research involves disentangling the effects of different kinds of stressors, using bioindicators, reef surveys, and sediment and coral geochemistry. Current projects on tropical corals include a submarine mine tailings disposal site in Sulawesi, Indonesia, and nearby reefs subject to other stresses, including mercury pollution from artisanal (small-scale) mining. Deep-sea corals are an important component of deep-sea ecosystems in Newfoundland and Labrador. Working with DFO and fisheries observers, we are documenting coral distribution based on records in bycatch, both from DFO survey trawls and commercial fisheries monitored by observers. In 2007, we completed the first-ever ROV mission to study deep-sea corals in Newfoundland waters. Deep-sea corals are long-lived organisms that can archive records of oceanographic change in their skeletons. We are describing the growth rates and longevities of a variety of deep-sea coral species from Newfoundland and Labrador waters using growth rings are radiocarbon ages. In addition, we are exploring the use of skeletal trace-element geochemistry of deep-sea corals as an oceanographic monitor. This research is closely related to new research on benthic habitat mapping in Newfoundland waters using multibeam bathymetry, and ground-truthed using grab samples, towed camera surveys, and SCUBA surveys. Finally, fossil coral reefs have played an important role in marine biodiversity throughout Earth history. I participate in several group projects on fossil reef paleoecology, including Devonian reefs of Arctic Canada and Pleistocene-Holocene reefs of Papua New Guinea. These projects aim to understand the environmental constraints on the growth of these fossil reefs, their community paleoecology, their modes of fossilization, and how the limits on preservation affect interpretations such as Quaternary sea-level curves.
