Sea ice meiofauna distribution on local to pan‐Arctic scales

open access: yesEcology and Evolution, 2018
Arctic sea ice provides microhabitats for biota that inhabit the liquid‐filled network of brine channels and the ice–water interface. We used meta‐analysis of 23 published and unpublished datasets comprising 721 ice cores to synthesize the variability in

Oil tanker under ice loadings

open access: yesScientific Reports, 2023
As a result of global warming, the area of the polar pack ice is diminishing, making merchant travel more practical. Even if Arctic ice thickness reduced in the summer, fractured ice is still presenting operational risks to the future navigation.

2017 State-of the Science of Dispersants and Dispersed Oil (DDO) in U.S. Arctic Waters: Physical Transport and Chemical Behavior [PDF]

open access: yes, 2017
Chemical dispersants were employed on an unprecedented scale during the Deepwater Horizon oil spill in the Gulf of Mexico, and could be a response option should a large spill occur in Arctic waters. The use of dispersants in response to that spill raised

The Impact of the Extreme Winter 2015/16 Arctic Cyclone on the Barents-Kara Seas [PDF]

open access: yes, 2016
Atmospheric data from the Atmospheric Infrared Sounder (AIRS) were used to study an extreme warm and humid air mass transported over the Barents–Kara Seas region by an Arctic cyclone at the end of December 2015. Temperature and humidity in the region was

CCDC80 suppresses high‐grade serous ovarian cancer migration via negative regulation of B7‐H3

open access: yesMolecular Oncology, EarlyView.
PAX8 is a lineage‐specific master regulator of transcription in high‐grade serous ovarian cancer (HGSC) progression. We show for the first time that PAX8 facilitates proliferation and metastasis by repressing the cell autonomous tumor suppressor CCDC80 and inducing B7‐H3 expression.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Automatic detection of Arctic polynyas using hybrid supervised-unsupervised deep learning [PDF]

open access: yesThe Cryosphere
Polynyas are open water or thin-ice areas within the ice pack. They play a crucial role for the Earth system, from deep water to cloud formation, causing large gas exchanges, and acting as hotspots for marine life.

Microglial dynamics and ferroptosis induction in human iPSC‐derived neuron–astrocyte–microglia tri‐cultures

open access: yesFEBS Open Bio, EarlyView.
A tri‐culture of iPSC‐derived neurons, astrocytes, and microglia treated with ferroptosis inducers as an Induced ferroptosis model was characterized by scRNA‐seq, cell survival, and cytokine release assays. This analysis revealed diverse microglial transcriptomic changes, indicating that the system captures key aspects of the complex cellular ...

CLIMATE CHANGE AT HIGH LATITUDES: AN ILLUMINATING EXAMPLE

open access: yesZygon, 2018
A striking example is presented of a newly observed phenomenon in the ice‐covered Arctic Ocean that appears to be a consequence of changes in the physical forcing.

Environmental drivers of under-ice phytoplankton bloom dynamics in the Arctic Ocean

open access: yesElementa: Science of the Anthropocene, 2020
The decline of sea-ice thickness, area, and volume due to the transition from multi-year to first-year sea ice has improved the under-ice light environment for pelagic Arctic ecosystems.
