Project background

The Southern Ocean is a critical component of the global climate system, where heat is lost from the ocean to the atmosphere, strong winds stir and mix the waters, and sea ice forms and melts. These processes combine to make the ocean water sufficiently dense to descend into the deep ocean, sequestering carbon, so the interaction between ocean, ice and atmosphere is critical to get right in our climate models.  However these interactions are poorly quantified and challenging to model, so better observations are needed (reference 1). This project aims to make key observations in a location rarely accessed, the continental shelf of Antarctica, as part of a major UK project named PICCOLO.

Research Methodology

You will calculate heat and freshwater fluxes from observations made during the exciting PICCOLO field campaign using a range of autonomous vehicles deployed on the Antarctic continental shelf in the western Weddell Sea. This will include temperature, salinity, velocity and turbulent mixing from a fleet of ocean gliders (references 2,3), together with atmospheric measurements from an autonomous surface vehicle Caravela (reference 4). These high spatial- and temporal- resolution but short-duration measurements will be complemented by year-long time series of ocean measurements from profiling floats and a mooring. You will use idealised numerical models to interpret the observations and explore the physical processes of sea ice formation and melting, wind mixing and surface cooling.

Training

This project will provide you with a thorough training in physical oceanography, data analysis,

and interactions between ocean, ice and atmosphere. You will have the opportunity to participate in a Southern Ocean field campaign to gain oceanographic observational expertise, and to pilot ocean gliders. You will join the multidisciplinary PICCOLO science team, and collaborate with PICCOLO scientists at other UK and international institutions. The project will equip you for a wide variety of careers, e.g. ocean/climate research, marine industries, consultancy.

Person specification

You will be keen to learn about the physics of the ocean and its interactions with the atmosphere and with ice.  You will have studied natural sciences, physics, mathematics, oceanography, meteorology or environmental sciences, and have good numerical skills. Some programming experience is desirable.

Key Information

  • This project has been shortlisted for funding by the ARIES NERC DTP and will start on 1st October 2023. The closing date for applications is 23:59 on 11th January 2023.
  • Successful candidates who meet UKRI’s eligibility criteria will be awarded a NERC studentship, which covers fees, stipend (£17,668 p.a. for 2022/23) and research funding. International applicants are eligible for fully-funded ARIES studentships including fees. Please note however that ARIES funding does not cover additional costs associated with relocation to, and living in, the UK.
  • ARIES students benefit from bespoke graduate training and ARIES provides £2,500 to every student for access to external training, travel and conferences, on top of all Research Costs associated with the project. Excellent applicants from quantitative disciplines with limited experience in environmental sciences may be considered for an additional 3-month stipend to take advanced-level courses.
