TL;DR: The animal communities and carbonates observed in the Oregon subduction zone occur in strata as old as 2.0 million years and provide criteria for identifying other localities where modern and ancient accreted deposits have vented methane, hydrocarbons, and other nutrient-bearing fluids.

TL;DR: In this paper, a Monte Carlo analysis of a published data set is performed to determine the probability that the imbalance can be explained purely by uncertainties in measurements and conversion factors, and two poorly quantified sources, lateral advection of particles and a population of slowly settling particles are discussed as providing a means of closing regional carbon budgets.

TL;DR: In this paper, the authors found that the seasonal evolution of first-year and multi-year ice permeability and surface morphology determine four distinct stages of melt, starting at the start of the ablation season (stage 1), ponding is widespread and lateral melt flow dominates.

TL;DR: The GEOTRACES Intermediate Data Product 2017 (IDP2017) as discussed by the authors is the second publicly available data product of the international GEOTrACES programme, and contains data measured and quality controlled before the end of 2016.

TL;DR: In this paper, the authors found that the seasonal evolution of first-year and multi-year ice permeability and surface morphology determine four distinct stages of melt, starting at the start of the ablation season (stage 1), ponding is widespread and lateral melt flow dominates.
