Funded Projects
Involved in WP 4.1, looking at
ice-sheet models of past and present inter-glacials. Other BAS
people
were Eric Wolff (now Dept. Earth Sciences, Cambridge University), Sarah Bradley
(now Dept. Geography, University of Sheffield) and Louise Sime.
Involved in WPs 2.1 (Frank
Pattyn,
Grounding Line) and 5.2 and 5.3 (both Tony Payne) which involve
AIS/GrIS modelling and Peninsula modelling respectively. Worked
with
Rob Arthern, Nick Barrand, Gisela Hiess and
Rosie Williams from BAS.
SW Ronne Retreat
I was PI of this NERC-funded
project, with Hugh Corr, Ed King, Jonny Kingslake, Carlos Martín
and Robert Mulvaney
(BAS); Mike Bentley (Durham); Project
Partners Nancy Bertler (VUW);
Howard Conway (UW), Fabien
Gillet (LGGE/UJF) and Matt King
(Newcastle, now Tasmania). Using Raymond Effect
Dating in the SW Ronne ice-rises e.g. Fletcher Promontory, Korff Ice Rise, with rheology constrained by
radar strain-rate measurements, to date retreat of grounding line
in SW Ronne area. Two field seasons, 2013-14 and 2014-15 . A poster on this subject by me,
Howard Conway, Nancy Bertler and Tollý Aðalgeirsdóttir
was presented at IGS British Branch Virtual Meeting 2020.
Part of Howard Conway's USAP
Roosevelt project, which is run in association with Nancy
Bertler's
RICE drilling project. I went there with the pRES in seasons
2010-11 and 2013-14.
With Mike Bentley, Andreas Vieli
and Pippa Whitehouse. Mike
collected
rocks for exposure age dating in season 2009-10; Pippa is
going to model the implications for AIS history with help from
Andreas
and me.
With Chris Clark,
Sarah Bradley,
Jeremy Ely, Gisela Hiess,
Niall Gandy, Ed Gasson, Lauren Gregoire
and Dave Pollard.
Chris and the BRITICE team collected a vast quantity of new data on the marine portions of the British
and Irish ice-sheets; modelling has started with teams of Chris, Jeremy and Sarah; Gisela and me; Niall
and Lauren; and Ed and Dave
Palmer Land GPS
With Matt King and Mike Bentley.
Measuring the PGR using continuous GPS in Palmer Land.
pRES at Summit and NEEM
I
was PI of this NERC-funded project, with Hugh Corr,
Adrian
Jenkins and Ed King; PDRA was Fabien Gillet-Chaulet. Used
the BAS phase-sensitive radar to
infer the Glen index for ice-flow.
Geophysical survey of sub-glacial
Lake Ellsworth for the main
drilling
project. With Martin Siegert, Neil Ross, John Woodward and,
from
BAS, Andy Smith, Hugh Corr, Ed King and David Vaughan.
With Chris Clark and many
others. Getting data about drumlins, guided by modelling
activities; an entertaining movie was made.
Radioglaciology
With
Gwendolyn Leysinger Vieli,
Howard Conway, Hugh Corr,
Fabien Gillet, Bob Hawley, Ed King and several others. Obtaining radar-layer data and using it in models.
Unfunded Projects
These are model
intercomparisons.
Intercomparison of higher-order
and
full Stokes solvers. I contributed five models: two full Stokes,
one
LMLa, one L1L2 and one L1L1.
Marine ice-sheet model
intercomparison, which I organised with Frank Pattyn and Christian
Schoof.
Marine ice-sheet model intercomparisons with two horizontal dimensions,
which I organised with Frank Pattyn, Olivier Gagliardini and Thomas Zwinger
