We are hosting fully funded PhD research projects through NEXUSS (Next Generation Unmanned System Science), a centre of doctoral training in the use of Smart and Autonomous Observation Systems (SAOS) for the environmental sciences, funded jointly by NERC and EPSRC.
Students are based at the Scottish Association for Marine Science (SAMS) in Oban, on the west coast of Scotland. SAMS is an academic partner of the University of the Highlands and Islands and is one of the UK’s premier marine research institutes. Check out other PhD projects that SAMS may be offering here.
We currently have one fully-funded studentship (apply by 1 June 2018):
Sounding out zooplankton: using autonomous wideband echosounders to characterise polar ecosystems
Krill and copepods (zooplankton, small marine organisms) are ubiquitous within the world’s oceans, and play a key role in polar marine foodwebs as food for higher trophic levels, including fisheries, and for carbon cycling. Yet we are still challenged to measure their abundance and distribution accurately and the challenge gets harder at larger temporal and spatial scales. Acoustic methods are used widely for estimating fish and plankton abundance and distribution, but there is ambiguity in the interpretation of acoustic data to species identification.
New wideband acoustic technology offers a potential way to characterise a range of sound scatterers including zooplankton by measuring acoustic responses continuously across a wide frequency range, increasing the amount of information available for spectral characterization of targets. In addition, compressed pulse processing can increase the temporal- and range-resolution, enabling enhanced feature extraction from within organism aggregations (e.g. krill swarms).
This project will use these next generation wideband autonomous echosounders, deployed vertically, in autonomous mode on moorings, and on autonomous vehicles to examine krill and copepod identification and distribution in polar waters and in a test-bed in Loch Etive, Scotland.
The student will develop methods for identifying krill and copepod echoes within wideband acoustic data, and make novel observations of the distribution of copepods and krill within aggregations and swarms. They will analyse existing data from moored echosounders to examine high range resolution acoustic data from within Antarctic krill swarms. Using their species identification technieques to identify krill, they will examine intra-swarm behaviour. Additional research opportunities may include analysing acoustic data from an Autonomous Underwater Vehicle deployment (eg echosounder mounted on Autosub and deployed within the Weddell Sea), where the student will examine vehicle behaviour and its influence on wideband species identification, or the association of zooplankton with sea ice, exploring the mechanisms and patterns of variability in zooplankton distribution. Where possible the student will also collect new data from vertical deployments of the wideband ecosounder with concurrent net sampling. We identify two opportunities for this: with supervisors at SAMS (Oban) as part of ongoing funded projects into zooplankton physiology / behaviour and during one of BAS' fieldwork campaigns (Southern Ocean), learning key practical skills. They will use the net samples to parameterise acoustic scattering models to describe key taxa, comparing modelled target strength frequency response curves with observed data to validate wideband species identification.
The NEXUSS CDT provides state-of-the-art, highly experiential training in the application and development of cutting-edge Smart and Autonomous Observing Systems for the environmental sciences, alongside comprehensive personal and professional development. There will be extensive opportunities for students to expand their multi-disciplinary outlook through interactions with a wide network of academic, research and industrial / government / policy partners. They will be registered at SAMS, part of the University of the Highlands and Islands where they will be primarily based. However they will also be hosted at the British Antarctic Survey and on occasion where necessary for training, St Andrews. At SAMS, the student will become part of a vibrant PhD community and supported and mentored by an experienced thesis panel. In this way, the student will experience research and work life at both universities and a government research centre. They will have access to a comprehensive suite of specific and generic training.
The broad set of skills of the student's supervisors will ensure that they gain experience of, and be trained in a number of lab, field and theoretical techniques available across the three institutes. Specifically, these will include:
- >Oceanography, ocean physics
- >Polar ecology, marine behavioural ecology
- >Seagoing/marine data collection skills
- >Fisheries acoustics, signal processing
- >Computing/processing of large data sets

Professor Finlo Cottier (physical oceanographer) - SAMS

Students will experience a programme of approximately 16 weeks of highly experiential training in the development and application of state-of-the-art SAOS technologies and approaches in the environmental sciences, alongside comprehensive personal and professional development.
There will be extensive opportunities for students to expand their multi-disciplinary outlook through interactions with a wide network of academic, research, industry, government and policy partners.
Our vision is to develop, deliver and disseminate the world's first environmental science doctoral training programme founded around competitive team grand challenges (GCs) that are sponsored fully by industry.
Annual GC events will be the centre piece of the NEXUSS community, in which first year student teams with mixed skill sets coached by senior student cohorts will design and deploy SAOS technologies and apply vigorous data analysis techniques to address and report on a simulated, real-world environmental problem.
The fortnight long GC finale will entail field trials, competitive field demonstrations, and team presentations of scientific results to a panel of customers. The GC activities and timeline will maximinse peer-learning and cohort building, and grow and consolidate the set of skills underpinning the end-to-end use of SAOS approaches in a realistic context, with access to world-class, cross-cutting facilities and expertise.
The studentships will be funded for 44 months and will follow standard RCUK (Research Council UK) conditions. The studentships are open to UK nationals and applicants should have, or expect to obtain, a first class or upper second-class honours degree or a Master's degree in the relevant subject area.
