Professor Eugene Murphy

Is an Emeritus Fellow of the British Antarctic Survey (BAS), which is part of the Natural Environment Research Council (NERC), UKRI. Between 1998 and 2022 he led the Ecosystems Programme as Principal Investigator and Science Leader. He was also an Individual Merit Promotion Scientist (IM Band 3) and a Visiting Professor at the University of Newcastle until 2022.  He is currently an Honorary Professor in the School of Environmental Sciences, University of East Anglia and an Adjunct Professor at the University of Tasmania.  He has a BSc in Marine Biology and a PhD in fisheries science and modelling and has over 40 years research experience.  In 2014 Eugene was appointed the Science Leader of the Ecosystems Team, which is part of the BAS Science Portfolio: Polar Science for Planet Earth.  Over the previous 15 years he led two large research programmes examining the dynamics of Southern Ocean ecosystems.  His research background is in ocean ecosystem science and ecological modelling, with expertise in population dynamics, food webs, physical and biological process interactions, biogeochemistry, fisheries science.  He has undertaken and led research projects on data analyses and modelling and at sea studies, including as lead scientist in the Antarctic.

Eugene has published over 100 peer-reviewed articles across a wide range of marine science.   He has served on a range of national and international grant and programme review bodies over the last 25 years.  During that time he has been active in the development of science in the Southern Ocean to address issues of fishery management and sutainability under the Commission for Conservation of Antarctic Marine Living Resources (CCAMLR).  He was involved in the IGBP Global Ocean Ecosystem Dynamics Programme (GLOBEC) in aspects of ocean ecosystem modelling and Southern Ocean science for over 10 years.  More recently he led the development of the international Integrating Climate and Ecosystem Dynamics Southern Ocean programme (ICED), developing analyses of circumpolar Southern Ocean ecosystems.   He is also currently a member of the scientific steering committee and Vice-Chair of the global ocean programme Integrating Marine Biosphere Research (IMBeR) co-sponsored by SCOR and Future Earth.

Research interests

Prof. Eugene J. Murphy

 

My main focus is on the controls on the structure and functioning (operation) of ocean ecosystems and how physical-chemical and biological process interactions at different scales affect the ecosystem structure.  This requires a multi-disciplinary approach that combines oceanographic and ecological studies. The geographical focus of my research has been the Southern Ocean and the ecological focus has centred on Antarctic krill, which is a key species in Southern Ocean food webs.

Particular topics of interest include: the role of zooplankton in marine food webs, zooplankton population dynamics, coupled models of krill dynamics and dispersal, predator-prey interactions in patchy systems, connectivity in ocean ecosystems, cross scale processes, food web modelling, end-to-end modelling of ecosystems and emergent structure of ecosystems, variability in oceanic ecosystems, impacts of fisheries and climate change in ocean ecosystems, linking biogeochemical and food web processes, sustainable management of fisheries and the role of ecological processes in the Earth System.

Specific achievements include:

• Scale-based approaches to analyses of ocean ecosystems that have influenced national Southern Ocean research efforts for over 25 years and contributed to global understanding of the controls on the structure and functioning of ocean ecosystems.
• Integrated assessment of the structure and functioning of large scale ocean ecosystems focussed on the Scotia Sea region of the Southern Ocean.
• Development of understanding of how climate variability across the Southern Hemisphere affects ocean and sea-ice and the structure and functioning of oceanic ecosystems.
• Elucidation of the role of advection in the dispersal and distribution of krill populations and in maintenance of ecosystem structure in the Southern Ocean.
• Models of the population dynamics of krill and coupled physical-biological models of their dispersal, growth and survival.
• Models of predator-prey processes and the impacts of historical and future change on krill and ecosystems in the Southern Ocean.
• Development and maintenance of one of the longest multi-disciplinary and multi-trophic long term ecological observational sites in the Southern Ocean and one of the few available for any area of the world ocean.
• Contributions to the development of ecosystem based approaches to sustainable management of marine living resources through the Commission for Conservation of Antarctic Marine Living Resources (CCAMLR).
• Development of international integarted analyses of the structure and fucntioning of circumpolar Southern Ocean ecosystems and the interactive effects of climate change.
• Development of scenarios, models and projections of future change in Southern Ocean and global ocean ecosystems.

Current research

The focus is on developing large-scale (to circumpolar) analyses and models of the controls on the structure and functioning of Southern Ocean, Arctic and global ocean ecosystems.

Specific projects include

• Analyses of the variability and impacts of variability on the structure and functioning of ocean ecosystems and key species.
• Modelling the life cycle of Antarctic krill to predict circumpolar distribution and abundance.
• Developing approaches to modelling the structure and functioning of oceanic food webs as part of work on the end-to-end operation of ecosystems.
• Comparative analyses of the structure and functioning of Antarctic and Arctic ocean ecosystems and the impacts of change in polar ecosystems.
• Analyses of the combined effects of climate change, fisheries and other human activities on the structure and functioning of ocean ecosystems and key species.

How will Southern Ocean ecosystems be affected by future climate-related change? 

As part of our international efforts in the ICED programme to develop projections of the future state of Southern Ocean ecosystems we are working to develop an agreed set of scenarios of how Southern Ocean environments may change.  The aim is to provide a robust basis for assessing the potential effects of change in ocean ecosystems.  In this study, we brought together a team of scientists to undertake a multidiscplinary assessement of available physical and chemical projections.  We focussed patrticularly on sea ice, which is a crucial component of Southern Ocean ecosystems.   We applied simple ecological criteria to select a subset of the available  climate projection models (CMIP5) that best reproduced the historical pattern of seasonal sea ice formation and retreat.  This process highlighted the importance of developing a mutlidicplinary approach to anlysing the potential impacts of future climate change in ocean ecosystems.  It also provides a basic model approach for generating an agreed set of scenarios for developing ecological projections.  The work is being developed  (in conjunction with CCAMLR) to generate projections (with uncertainties) of the potential impacts of change in Southern Ocean ecosystems to help inform decision making for conservation and management.
