A new projection of sea level change in response to collapse of marine sectors of the Antarctic Ice Sheet
Gomez, Natalya; Mitrovica, Jerry; Tamisiea, Mark E.; Clark, Peter U. (Oxford University Press, 2010)We present gravitationally self-consistent predictions of sea level change that would follow the disappearance of either the West Antarctic Ice Sheet (WAIS) or marine sectors of the East Antarctic Ice Sheet (EAIS). Our ... -
A probabilistic assessment of sea level variations within the last interglacial stage
Kopp, Robert E.; Simons, Frederik J.; Mitrovica, Jerry; Maloof, Adam C.; Oppenheimer, Michael (Oxford University Press, 2013)The last interglacial stage (LIG; ca. 130-115 ka) provides a relatively recent example of a world with both poles characterized by greater-than-Holocene temperatures similar to those expected later in this century under a ... -
A statistical filtering approach for Gravity Recovery and Climate Experiment (GRACE) gravity data
Davis, J. L.; Tamisiea, M. E.; Elósegui, P.; Mitrovica, Jerry; Hill, E. M. (American Geophysical Union, 2008) -
Anelasticity across seismic to tidal timescales: a self-consistent approach
Lau, Harriet C. P.; Faul, Ulrich; Mitrovica, Jerry; Al-Attar, David; Tromp, Jeroen; Garapić, Gordana (Oxford University Press, 2017) -
BIFROST project: 3-D crustal deformation rates derived from GPS confirm postglacial rebound in Fennoscandia
Scherneck, Hans-Georg; Johansson, Jan M.; Vermeer, Martin; Davis, James L.; Milne, Glenn A.; Mitrovica, Jerry (SpringerOpen, 2001)Since autumn 1993 the BIFROST project has provided daily GPS solutions of geodetic positions from a network of more than 40 stations covering, a large area of the Baltic shield. This area is expected to show large vertical ... -
Coastal paleogeography of the California–Oregon–Washington and Bering Sea continental shelves during the latest Pleistocene and Holocene: implications for the archaeological record
Clark, Jorie; Mitrovica, Jerry; Alder, Jay (Elsevier, 2014)Sea-level rise during the last deglaciation and through the Holocene was influenced by deformational, gravitational, and rotational effects (henceforth glacial isostatic adjustment, GIA) that led to regional departures ... -
Constraining proposed combinations of ice history and Earth rheology using VLBI determined baseline length rates in North America
Mitrovica, Jerry; Davis, J. L.; Shapiro, I. I. (American Geophysical Union, 1993)We predict the present-day rates of change of the lengths of 19 North American baselines due to the glacial isostatic adjustment process. Contrary to previously published research, we find that the three-dimensional motion ... -
Continuous GPS measurements of postglacial adjustment in Fennoscandia: 2. Modeling results
Milne, Glenn A.; Mitrovica, Jerry; Scherneck, Hans-Georg; Davis, James L.; Johansson, Jan M.; Koivula, Hannu; Vermeer, Martin (American Geophysical Union, 2004)[1] Data collected under the auspices of the BIFROST GPS project yield a geographically dense suite of estimates of present-day, three-dimensional (3-D) crustal deformation rates in Fennoscandia [Johansson et al., 2002]. ... -
Departures from eustasy in Pliocene sea-level records
Raymo, Maureen E.; Mitrovica, Jerry; O’Leary, Michael J.; DeConto, Robert M.; Hearty, Paul J. (Nature Research, 2011)Proxy data suggest that atmospheric CO2 levels during the middle of the Pliocene epoch (about 3 Myr ago) were similar to today, leading to the use of this interval as a potential analogue for future climate change. Estimates ... -
Detection of a Dynamic Topography Signal in Last Interglacial Sea-Level Records
Austermann, Jacqueline; Mitrovica, Jerry; Huybers, Peter; Rovere, Alessio (American Association for the Advancement of Science (AAAS), 2017-07-07)Estimating minimum ice volume during the last interglacial based on local sea-level indicators requires that these indicators are corrected for processes that alter local sea level relative to the global average. Although ... -
A detection of Milankovitch frequencies in global volcanic activity
Kutterolf, Steffen; Jegen, Marion; Mitrovica, Jerry; Kwasnitschka, Tom; Freundt, Armin; Huybers, Peter John (Geological Society of America, 2013)A rigorous detection of Milankovitch periodicities in volcanic output across the Pleistocene-Holocene ice age has remained elusive. We report on a spectral analysis of a large number of well-preserved ash plume deposits ... -
Earth rotation changes since ?500 CE driven by ice mass variations
Hay, Carling; Mitrovica, Jerry; Morrow, Eric; Kopp, Robert E.; Huybers, Peter John; Alley, Richard B. (Elsevier BV, 2016)We predict the perturbation to the Earth's length-of-day (LOD) over the Common Era using a recently derived estimate of global sea-level change for this time period. We use this estimate to derive a time series of “clock ... -
Earth's gravitational field: seismic tomography resolves the enigma of the Laurentian anomaly

Elemental Fluxes to the Seafloor: Pleistocene Climate and Submarine Hydrothermal Activity
Middleton, Jennifer L. (2018-01-03)Marine sedimentary records of major and trace element deposition provide a means to examine the temporal variability and interactions between a wide variety of Earth processes, including fluctuations in atmospheric and ... -
An enigma in estimates of the Earth's dynamic ellipticity
Morrow, E; Mitrovica, Jerry; Forte, A.M.; Glišović, P; Huybers, Peter John (Oxford University Press, 2012)The precession and obliquity frequencies of the Earth’s rotational motion are functions of the dynamic ellipticity of the Earth’s gravitational figure, and this connection has provided a novel bridge between studies of ... -

Estimates of Land Ice Changes from Sea Level and Gravity Observations
Morrow, Eric (2014-06-06)Understanding how global ice volume on the Earth has changed is of significant importance to improving our understanding of the climate system. Fortunately, the geographically unique perturbations in sea level that result ... -
Evolution of a Coupled Marine Ice Sheet–Sea Level Model
Gomez, Natalya Alissa; Pollard, David; Mitrovica, Jerry; Huybers, Peter John; Clark, Peter U. (American Geophysical Union, 2012)We investigate the stability of marine ice sheets by coupling a gravitationally self-consistent sea level model valid for a self-gravitating, viscoelastically deforming Earth to a 1-D marine ice sheet-shelf model. The ... -
Forward and inverse modelling of post-seismic deformation
Crawford, Ophelia; Al-Attar, David; Tromp, Jeroen; Mitrovica, Jerry (Oxford University Press, 2017)We consider a new approach to both the forward and inverse problems in post-seismic deformation. We present a method for forward modelling post-seismic deformation in a self-gravitating, heterogeneous and compressible earth ... -
