A realistic projection of climate change in the upper atmosphere into the 21st century
Read more of: A realistic projection of climate change in the upper atmosphere into the 21st centuryClimate change in the upper atmosphere (∼90 − 500 km altitude) has important impacts on practical applications. To prepare for these, realistic projections of future climate change are needed. The […]

Does tectonic deformation control episodic continental arc magmatism? Evidence from granitic magnetic fabrics (AMS)
Read more of: Does tectonic deformation control episodic continental arc magmatism? Evidence from granitic magnetic fabrics (AMS)This paper applies magnetic fabric analyses to plutons of the East Pacific continental arc. Continental arc magmatism is strongly episodic, with voluminous granitic magma addition occurring during discrete high-flux events […]

Emerging Technologies and Approaches for In Situ, Autonomous Observing in the Arctic
Read more of: Emerging Technologies and Approaches for In Situ, Autonomous Observing in the ArcticUnderstanding and predicting Arctic change and its impacts on global climate requires broad, sustained observations of the atmosphere-ice-ocean system, yet technological and logistical challenges severely restrict the temporal and spatial […]

Deep carbon export peaks are driven by different biological pathways during the extended Scotia Sea (Southern Ocean) bloom
Read more of: Deep carbon export peaks are driven by different biological pathways during the extended Scotia Sea (Southern Ocean) bloomEstimating the amount of organic carbon leaving the upper water column and becoming sequestered in the deep ocean is a major challenge in our understanding the oceanic C cycle. This […]

Multiple carbon cycle mechanisms associated with the glaciation of Marine Isotope Stage 4
Read more of: Multiple carbon cycle mechanisms associated with the glaciation of Marine Isotope Stage 4Here we use high-precision carbon isotope data (δ13C-CO2) to show atmospheric CO2 during Marine Isotope Stage 4 (MIS 4, ~70.5-59 ka) was controlled by a succession of millennial-scale processes. Enriched […]

Decadal Scale Variability of Larsen Ice Shelf Melt Captured by Antarctic Peninsula Ice Core
Read more of: Decadal Scale Variability of Larsen Ice Shelf Melt Captured by Antarctic Peninsula Ice CoreIn this study, we used the stable water isotope record (δ18O) from an ice core drilled in Palmer Land, southern Antarctic Peninsula (AP). Utilizing δ18O we identified two climate regimes […]

Global phylogeography of hyperdiverse lanternfishes indicates sympatric speciation in the deep sea
Read more of: Global phylogeography of hyperdiverse lanternfishes indicates sympatric speciation in the deep seaLanternfishes (Myctophidae) are one of the most species-rich families of mid-water fishes. They inhabit the mesopelagic zone, where physical barriers to dispersal and gene flow are permeable. Thus, modes of […]

The importance of ion composition for radiation belt modeling
Read more of: The importance of ion composition for radiation belt modelingThe banded structure of Electromagnetic Ion Cyclotron (EMIC) wave spectra and their resonant interactions with radiation belt electrons depend on the cold ion composition. However, there is a great deal […]

The influence of tides on the marine carbonate chemistry of a coastal polynya in the south-eastern Weddell Sea
Read more of: The influence of tides on the marine carbonate chemistry of a coastal polynya in the south-eastern Weddell SeaTides significantly affect polar coastlines by modulating ice shelf melt and modifying shelf water properties through transport and mixing. However, the effect of tides on the marine carbonate chemistry in […]
