[Met-jobs] PhD studentship on Antarctic Bottom Water at British Antarctic Survey, University of Southampton, and National Oceanography Centre

From "Abrahamsen, Povl" <epab@bas.ac.uk>

Dear colleagues,

As part of the NERC-funded INSPIRE doctoral training partnership 
(https://www.inspire-dtp.ac.uk/), we are seeking applicants for a PhD 
studentship entitled "What controls the warming of the Antarctic Bottom Water 
supply to the Atlantic Ocean?". This is a joint project between the British 
Antarctic Survey (in Cambridge), the University of Southampton, and the 
National Oceanography Centre (in Southampton), with supervisors Povl Abrahamsen 
(BAS), Alberto Naveira Garabato (UoS), Eleanor Frajka-Williams (NOC), and Mike 
Meredith (BAS). The brief project description is:

During the last three decades, the Antarctic Bottom Water (AABW) that fills the 
bulk of the ocean abyss has exhibited a striking warming and contraction in 
volume over much of the world ocean, particularly in the Atlantic basin. While 
the causes of these changes are unknown, available evidence suggests that, in 
the Atlantic Ocean, the warming and contraction of AABW may be caused by 
changes in the strength and configuration of winds over the Weddell Sea, where 
much AABW is produced. AABW is the densest of the world’s water masses, and is 
particularly important to global climate because of its role in drawing down 
heat and carbon into the depths of the ocean.

This project will test and quantify this hypothesis by (i) determining how the 
flow and properties of the AABW entering the Atlantic Ocean from the Weddell 
Sea respond to wind forcing, and (ii) assessing the dynamical processes 
connecting wind forcing perturbations to changes in AABW. The project will 
generate a thorough understanding of the ways in which changes in Antarctic 
winds may shape the heat content of the deepest layers of the global ocean 
abyss.

 Links to eligibility criteria and how to apply can be found at 
http://www.inspire-dtp.ac.uk/how-apply. The deadline for applications is 3 Jan 
2020, with interviews in late February, and project start in late September 
2020.

If you have any questions, please feel free to get in touch.

Kind regards,

Povl
