What am I investigating?

My research explores colonies of animals on the ocean floor, to understand patterns of life in the deep sea that covers most of our world, so that we can make more informed choices for its future.

By studying marine life in "island-like" habitats such as hydrothermal vents, my work examines interactions between ecology ("who does what"), biogeography ("who lives where"), and evolution ("who is related to whom") in the deep sea.

I have published more than fifty research papers, worked on grants totalling more than £1.4 million in funding during the past ten years, contributed to consultations by policymakers to guide the protection of deep-sea habitats, and produced a 4* "Impact Case Study" in the UK's REF2014 assessment.


Research projects

My recent projects have explored four areas:

* East Scotia Ridge, Southern Ocean

* Mid-Cayman Spreading Centre, Caribbean

* Mid-Atlantic Ridge north of the Azores

* the SW Indian Ridge

My work in these areas addresses three main topics
(and for a full list of research papers, please see Publications):


(1) Global biogeography of deep-sea chemosynthetic environments

(e.g. Chen et al., 2017; Copley et al., 2016; Anderson et al., 2016; Chen et al., 2015a; Roterman et al., 2013; Connelly et al., 2012; Rogers et al., 2012; Copley et al. 2007a)


Why do we find particular species of animals at hydrothermal vents in some areas but not elsewhere? Why are some types of animals more widespread than others in habitats such as hydrothermal vents or cold seeps around the world? These are the big questions, and answering them should give us a better understanding of how species disperse and evolve in deep-sea habitats. Answering them also involves describing new species from the areas that we are exploring, and analysing their genetic code to determine how they are related to other species elsewhere.


Here are some of the new species that my colleagues and I have described from expeditions:
* Dracogyra subfuscus & Lirapex politus Chen, Zhou, Wang & Copley 2017 (deep-sea vent snails)
* Pachycara caribbaeum Anderson, Somerville & Copley 2016 (deep-sea eelpout fish)
* Gigantopelta chessoia & Gigantopelta aegis Chen et al. 2015b ("giant" peltospirid snails)
* Paulasterias tyleri Mah et al. 2015 (seven-armed seastar)
* Chrysomallon squamiferum Chen, Linse, Copley & Rogers 2015 ("scaly-foot" snail)
* Osedax rogersi & Osedax crouchi Amon et al. 2014 (bone-eating "zombie" worms)
* Lebbeus virentova Nye, Copley, Plouviez & Van Dover 2013 ("green goolie" shrimp)
* Iheyaspira bathycodon Nye, Linse, Copley & Plouviez 2013 (deep-sea snail)
* Rimicaris hybisae Nye, Copley & Plouviez 2012 (world's deepest known vent shrimp)


(2) Spatial & temporal dynamics of faunal assemblages in insular & ephemeral deep-sea habitats

(e.g. Amon et al., 2017; Copley et al., 2016; Amon et al., 2013; Marsh et al., 2013; Marsh et al., 2012; Copley et al., 2007b)


Within a hydrothermal vent field, cold seep, or whale-fall, my goal is to understand what lives where and why. For example, why are some species abundant on vent chimneys, while other species only thrive at the edge of a vent field?


Unfortunately we can't stroll around the ocean floor as easily as ecologists do on rocky shores to investigate their patterns of life, so we are developing new techniques to study the microdistribution of animals in these environments, using high-definition cameras and the precision-control capabilities of the latest generation of remotely operated vehicles (ROVs).


(3) Life-history biology of species occupying insular & ephemeral deep-sea habitats

(e.g. Chen et al., 2018; Roterman et al., 2016; Amon et al., 2015; Marsh et al., 2015; Nye & Copley, 2014; Nye et al., 2013; Copley et al., 2007b; Copley & Young, 2006; Copley et al., 2003)


How do animals "hop" from vent to vent, or seep to seep, or whale skeleton to whale skeleton, in the deep ocean? The species we find in these island-like habitats on the ocean floor seem to have a variety of life cycles, types of larval development, and reproductive patterns. But are some features of their life-history biology "preadaptations" for success in these environments? And what are the consequences of differences in life-history biology for dispersal, gene flow, and ultimately biogeography?


My work in this area involves characterising the life-cycles of animals from hydrothermal vents, cold seeps, whale-falls, and wood-falls, in conjunction with studies of the genetics of their populations by colleagues around the world.
