Deep Sea Coral of Newfoundland and Labrador.

Fish and corals

Researcher:  Dr Evan Edinger

This project maps the distributions of deep-sea corals in Newfoundland and Labrador waters.  Roughly twenty species of deep-sea corals occur in our region, mostly along the continental shelf edge and continental slope. 

Deep-sea corals are long-lived, and many species have growth rings analogous to tree rings.  Deep-sea coral skeletons may provide important archives of oceanographic history on the scale of several centuries.

Stable isotope and trace element analysis of coral tissue and skeleton may reveal information on coral diets, and on regional oceanographic conditions.  New joint research with MUN and DFO will examine coral biochemisty, geochemistry, reproduction and recruitment, and associated invertebrate diversity.
