A Workflow to Address Uncertainties in Frontier Areas and Underexplored Basins by Integrating Palaeo-Environmental and Depositional Models with Stratigraphic Forward Modelling: A Case Study for the Shu'aiba Formation
TL;DR: In this paper, the Shu'aiba stratigraphic forward model (SFM) is used to estimate reservoir thickness and facies distribution in underexplored basins.

North African Humid Periods over the past 800000 years – Timing, Amplitude and Forcing
TL;DR: In this paper , the authors presented an 800kyr climate dataset produced using a recently developed version of the HadCM3B coupled climate model that simulates 20 North African Humid Periods over the past 800 kyr which have good agreement with the timing and amplitude of NAHPs identified in proxy data.

Constraining the global niche suitability of the Eusuchia clade across the Cretaceous-Paleogene boundary
TL;DR: This paper used species distribution models of extant crocodilians to infer the ecological niche of related taxa in the Maastrichtian and Danian, and found that while temperature is of significance to crocodilian biogeography, it is precipitation that is the most influential climatic variable.

TL;DR: In this paper , the authors investigated how Holocene environmental changes affected the evolutionary ecology of polar bears around Greenland and found that Greenlandic polar bears have been heavily influenced by changes in sea-surface temperature (SST) and sea-ice cover.
Journal ArticleDOI
Palaeoclimate: Implications of ocean expansion
Mark Siddall,Paul J. Valdes +1 more
TL;DR: The contributions of ice melt and ocean thermal expansion to sea-level rise during the last interglacial period are poorly constrained as discussed by the authors, and a new quantification of their roles implies that the Antarctic ice sheet may be more sensitive to climate change than once thought.
