DOI: 10.1016/j.epsl.2017.12.016
Abstract: Abstract North Atlantic Deep Water (NADW) currently redistributes heat and salt between Earth's ocean basins, and plays a vital role in the ocean-atmosphere CO2 exchange. Despite its crucial role in today's climate system, vigorous debate… read more here.

A quantitative analysis of transtensional margin width

DOI: 10.1016/j.epsl.2018.03.003
Abstract: Abstract Continental rifted margins show variations between a few hundred to almost a thousand kilometres in their conjugated widths from the relatively undisturbed continent to the oceanic crust. Analogue and numerical modelling results suggest that… read more here.

DOI: 10.1016/j.icarus.2016.07.023
Abstract: Abstract We give an explanatory description of the unusual “climate zones” on Pluto that arise from its high obliquity (mean 115°) and high amplitude (±12°) of obliquity oscillation over a 2.8 million year period. The… read more here.

DOI: 10.1016/j.icarus.2018.07.021
Abstract: Abstract Shallow Radar soundings of the south polar layered deposits (SPLD) have revealed buried CO 2 ice with as many as three distinct layers separated by thinner layers of water ice (Bierson et al., 2016). This… read more here.

Evolution of the obliquity of an exoplanet: A non-resonant case

DOI: 10.1016/j.icarus.2019.07.005
Abstract: Abstract We investigate analytically and numerically the variation of the obliquity (the axial tilt) of a hypothetical exo-Earth. A large number of exoplanets was discovered recently; since not much information is available about the masses… read more here.

Relative influence of precession and obliquity in the early Holocene: Topographic modulation of subtropical seasonality during the Asian summer monsoon

DOI: 10.1016/j.quascirev.2018.05.021
Abstract: Abstract On orbital timescales, higher summer insolation is thought to strengthen the continental monsoon while weakening the maritime monsoon in the Northern hemisphere. Through simulations using the Community Earth System Model, we evaluated the relative… read more here.

DOI: 10.1016/j.tecto.2019.01.003
Abstract: Abstract We investigated the variability of the first-order crustal structure and early post-rift stratigraphy of six segments of the African Equatorial Atlantic margin using sub-surface data (seismic and wells). Extension obliquity of the segments varies… read more here.

DOI: 10.1029/2019tc005886
Abstract: Strain partitioning onto margin‐parallel thrust and strike‐slip faults is a common process at obliquely convergent plate margins, leading to the formation and migration of crustal slivers. The degree of strain partitioning and rate of sliver… read more here.

Abstract: Aims: It has recently been shown that the fast migration of Titan could be responsible for the current 26.7°-tilt of Saturn's spin axis. We aim to quantify the level of generality of this result and… read more here.
