Reviews of Geophysics, Volume 64, Issue 1, March 2026.Abstract Sea ice is a crucial component of polar climate systems and is undergoing substantial changes in both hemispheres due to evolving climatic conditions. Arctic sea ice is transitioning from perennial to seasonal cover, and the Southern Ocean sea ice is exhibiting recent minima and enhanced seasonality.

Constraints on Noble Gas Variability in OIB and MORB From Non‐Equilibrium Magmatic Degassing Models
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Noble gas concentrations in ocean island basalts (OIB) and mid‐ocean ridge basalts (MORB) are affected by degassing processes, obscuring their pre‐eruptive characteristics. Degassing corrections commonly assume near‐equilibrium partitioning of noble gases between melt and vapor.

Stokes posets and serpent nests
, 2015 We study two different objects attached to an arbitrary quadrangulation of a regular polygon. The first one is a poset, closely related to the Stokes polytopes introduced by Baryshnikov.

Carbonate sedimentology: An evolved discipline
The Depositional Record, Volume 12, Issue 1, February 2026.Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

A new definition for m-Cambrian lattices
The Cambrian lattices, introduced in (Reading, 2006), generalize the Tamari lattice to any choice of Coxeter element in any finite Coxeter group. They are further generalized to the m-Cambrian lattices (Stump, Thomas, Williams, 2015). However, their definitions do not provide a practical setup to work with combinatorially.

Noncrossing arc diagrams and canonical join representations
, 2015 We consider two problems that appear at first sight to be unrelated. The first problem is to count certain diagrams consisting of noncrossing arcs in the plane. The second problem concerns the weak order on the symmetric group. Each permutation $x$ has a

Lattice Properties of Oriented Exchange Graphs and Torsion Classes
, 2018 The exchange graph of a 2-acyclic quiver is the graph of mutation-equivalent quivers whose edges correspond to mutations. When the quiver admits a nondegenerate Jacobi-finite potential, the exchange graph admits a natural acyclic orientation called the ...

, 2018 We define a natural lattice structure on all subsets of a finite root system that extends the weak order on the elements of the corresponding Coxeter group.
