Roles on external bodies
From an academic perspective my research is focused on understanding biodiversity patterns in the deep sea. I am interested in faunal zonation and species turnover with depth, as well as speciation along the depth gradient. More recently I have been investigating patchiness and faunal changes along isobaths, and trying to understand environmental drivers of deep-sea diversity and species distributions.
From an applied perspective my research is focused on sustainable management of the deep-sea ecosystem. In particular I am interested in research to support the design of effective marine protected area networks, including the creation of reliable habitat maps, and models of population connectivity that under-pin the design. See our group website www.deepseacru.org for more details.
The “One Ocean Hub” is a £20 million project funded by UK Research and Innovation (UKRI) through the Global Challenges Research Fund (GCRF) from 2019-2024. There are 24 research partners, and 35 project partner organisations. The Hub’s aim is to predict, harness and share equitably environmental, socioeconomic and cultural benefits from ocean conservation and sustainable use. I am one of 10 Co-Directors of the Hub and I Co-Lead the £4 million ‘Marine Non-Fishery Resources’ research programme within the Hub. My specific area of research on the project is focused on understanding and mapping marine (non-fishery) resources, which includes services like recycling of nutrients, carbon storage, oxygen generation, as well as potential biomedical values of marine animals like sponges. The project has a strong capacity building element and we are working with partner nations including South Africa, Namibia, Ghana, Seychelles, Fiji, Solomon Island, and the Caribbean region.
This is an interdisciplinary project involving oceanographers, marine biologists, hydrographic surveyors and biogeochemists from the University of Plymouth and the Manta Trust. It is part of a wider programme of research within BIOT . Our aim is to learn what processes and interactions sustain a healthy reef ecosystem. My focus is the mesophotic coral reef systems, their composition, connectivity, drivers of their distribution, and processes maintaining overall health.
UN Decade of Ocean Science for Sustainable Development / Challenger 150
I am currently coordinating efforts to develop a new 10 year deep-sea science programme for the Decade and to celebrate the 150th Anniversary of the Challenger Expedition. Please see the SCOR working group, DOSI working group and Challenger Deep-Sea Special Interest Group. Watch this space.......
Application of computer vision and artificial intelligence to seafloor image analysis and species identification.
This aspect of my research is embedded in multiple projects. I am coordinating international efforts to build an image reference archive for deep-sea species to support the future development of AI and CV. I am also trialing the use of AI and CV in AUV and ROV image data.
Deep-sea discovery - mining marine environments for novel biologics
The aim of this research project is to identify and develop potential new antimicrobials produced by the microbiome of sponges that live in the deep sea.
DEEPLINKS - Influence of population connectivity on depth-dependent diversity of deep-sea marine benthic biota .
Knowledge of how populations are connected is central to our understanding of population persistence, isolation, divergence, speciation and radiation. The bathyal region has been identified as the primary site of adaptive radiation in the deep-sea from molecular and morphological studies and is also where the peak in species diversity occurs in many ocean basins. Gene-flow is low over the depth gradient suggesting limited larval exchange occurs in the vertical. Recent research has suggested that larval dispersal potential may vary with depth.This variation, given the limited vertical exchange, may provide a mechanism for population isolation, divergence and speciation in the bathyal region. This study will adopt a multidisciplinary approach to investigate connectivity among deep-sea populations at different depths and spatial scales using: 1) larval dispersal modelling using Lagrangian particle tracking, driven by hydrographic models 2) population genetics/genomics and 3) benthic community analysis, using examples of sessile (scleractinian corals) and limited mobility (echinoid) species as test subjects. We will examine changes in larval dispersal, gene-flow,gene expression and community and taxonomic patterns with depth to identify possible variation in population connectivity down the vertical gradient. We will also examine patterns of connectivity at different spatial scales. Critically we will investigate whether the changes in connectivity from the shelf break to bathyal depths are correlated to current flow as predicted by hydrodynamic models and whether this physical mechanism significantly contributes to current patterns of diversity, potentially driving speciation at large spatial scales or, alternatively, whether other factors are influencing genetic structure.
