A local meteoric water line for interior Alaska constrains paleoclimate from 40 000 year old relict permafrost
Anthropogenic climate warming is degrading permafrost across interior Alaska. Information from past warming events provides long-term perspectives for future trajectories; however, late Quaternary seasonal temperatures are poorly constrained. We have established a stable water isotope meteoric water line for interior Alaska and measured stable water isotope values from 126 permafrost cores representing different ice types deposited over the past …
Seasonal variation in near-surface seasonally thawed active layer and permafrost soil microbial communities
Understanding how soil microbes respond to permafrost thaw is critical to predicting the implications of climate change for soil processes. However, our knowledge of microbial responses to warming is mainly based on laboratory thaw experiments, and field sampling in warmer months when sites are more accessible. In this study, we sampled a depth profile through seasonally thawed active layer and permafrost in the Imnavait Creek Watershed, Alaska, …
Red Chert Quarries in the Munsungun Lake Formation
Red chert attributed to the Munsungun Lake geologic formation located in northern Maine is common in terminal-Pleistocene, fluted-point-period lithic assemblages throughout New England. A visually identical material also appears in some later-period sites in coastal Maine. Until recently no bedrock source for this red chert showing convincing evidence of precontact use was known. Here we present the NKP site complex, a series of quarry-related st…
