British Antarctic Survey (BAS) is looking for an exceptional

Earth System Modeller - Carbon Cycle

to join Ice Dynamics and Palaeoclimate Team. BAS delivers and enables world-leading interdisciplinary research in the Polar Regions. We employ experts from many different professions to carry out our Science as well as keep the lights on, feed the research and support teams and keep everyone safe!

Working at BAS is rewarding.

Our skilled science, operational and support staff based in Cambridge, Antarctica and the Arctic, work together to deliver research that uses the Polar Regions to advance our understanding of Earth as a sustainable planet. Through our extensive logistic capability and know how BAS facilitates access for the British and international science community to the UK polar research operation. Numerous national and international collaborations, combined with an excellent infrastructure help sustain a world leading position for the UK in Antarctic affairs. British Antarctic Survey is a component of the Natural Environment Research Council (NERC), which is part of UK

As a valued member of our team, you'll be eligible for the following benefits:

30 days annual leave plus bank holidays and 2.5 privilege days Excellent civil service pension (with 26% or more employer contribution, depending on your band) 24 hours/365 days access to employee assistance programme (EAP - including support with physical, mental, social, health and financial issues) Flexible and family friendly working opportunities Cycle to work scheme Access to discounted shopping on a range of retail, leisure and lifestyle categories and much more.

You'll be joining

our team of ice core scientists at BAS and University of Cambridge working with collaborators all around the world on two major international ice core projects and modelling efforts. In particular, the group is playing several roles in the Beyond EPICA-Oldest Ice Core project (BE-OIC) is a collaborative European effort to obtain a continuous ice core record of climate and carbon cycle changes across the mid-Pleistocene. The project recently completed the drilling of a new deep Antarctic ice core that holds ice from up to 1.2 million years before present. Our role in the project is to contribute our expertise in high-resolution, continuous ice core gas analysis and make the first interpretations of the data with simple box models.

This is an opportunity

to significantly enhance those first interpretations with Earth System Models. You will have the chance to work closely with scientists collecting the first greenhouse data on the changes in CO2, CH4, and N2O, including the opportunity to help in the data collection. At BAS, you will be mentored by Dr. Thomas Bauska (expertise in ice core data) and Dr. Xu Zhang (expertise in climate modelling and integrated in the Earth System Modelling Team, led by Dr. Louise Sime.

In addition to Beyond EPICA, the team are currently working on:

Fate, Emissions and Transport of CH4 (FETCH4) is a global project supported by Schmidt Futures that aims to improve our understanding of methane levels in the atmosphere in the past, present and future. Our role is to help collect and analyse a new Greenland ice core to produce a detailed record over last ~150 years. REWIND is a new deep ice core drilling project on the Antarctic Peninsula, aiming to recover a 700-metre core spanning the past 20,000 years. The project seeks to reconstruct past sea ice extent, atmospheric circulation, and wind patterns to better understand their roles in the uptake and release of CO? from the Southern Ocean. These environmental records will be directly compared with a new high-resolution CO? dataset from the same core.

You'll be joining

a world-leading interdisciplinary research organisation, that is committed to recruiting talented people like you, progressing your career and giving you the support, you need to thrive at BAS.

Some of your main responsibilities will include:

Install and test an earth system model of intermediate complexity on the BAS HPC. Perform ensemble experiments of orbital-scale variability using a simple, efficient earth system model (i.e. with an energy balance atmospheric) and focus on the last glacial cycle. Within this large ensemble perform a smaller subset of "snapshot" experiments using a dynamic atmosphere. Analyse the ensemble by comparing to ice core data of atmospheric CO2, 13C-CO2, mean ocean temperature and other key carbon cycle data constraints from marine and terrestrial records. Perform feedback analysis on the data-constrained model results.
