Convergent evolution and horizontal gene transfer in Arctic Ocean microalgae

Life Science Alliance, 2023
The Arctic Ocean stands apart from other oceans. Using multiple genomes and transcriptomes from cultured and environmental sources, we found distinct genetic modifications in Arctic microalgae consistent with biogeographically constrained trait ...

Nitrogen Fixation in a Changing Arctic Ocean: An Overlooked Source of Nitrogen?

Frontiers in Microbiology, 2020
The Arctic Ocean is the smallest ocean on Earth, yet estimated to play a substantial role as a global carbon sink. As climate change is rapidly changing fundamental components of the Arctic, it is of local and global importance to understand and predict ...

An evaluation of the E3SMv1 Arctic ocean and sea-ice regionally refined model [PDF]

Geoscientific Model Development, 2022
The Energy Exascale Earth System Model (E3SM) is a state-of-the-science Earth system model (ESM) with the ability to focus horizontal resolution of its multiple components in specific areas.

Sensitivity of Arctic Surface Temperature to Including a Comprehensive Ocean Interior Reflectance to the Ocean Surface Albedo Within the Fully Coupled CESM2

Journal of Advances in Modeling Earth Systems, 2023
Almost all current climate models simplify the ocean surface albedo (OSA) by assuming the reflected solar energy without the ocean interior contribution.

Degradation pathways for organic matter of terrestrial origin are widespread and expressed in Arctic Ocean microbiomes

Microbiome, 2022
Background The Arctic Ocean receives massive freshwater input and a correspondingly large amount of humic-rich organic matter of terrestrial origin. Global warming, permafrost melt, and a changing hydrological cycle will contribute to an intensification ...

Arctic Ocean acidification over the 21st century co-driven by anthropogenic carbon increases and freshening in the CMIP6 model ensemble [PDF]

Biogeosciences, 2021
The uptake of anthropogenic carbon (Cant) by the ocean leads to ocean acidification, causing the reduction of pH and the saturation states of aragonite (Ωarag) and calcite (Ωcalc). The Arctic Ocean is particularly vulnerable to ocean acidification due to

Unprecedented decline of Arctic sea ice outflow in 2018

Nature Communications, 2022
Fram Strait is the major gateway connecting the Arctic Ocean and North Atlantic Ocean, where nearly 90% of the sea ice export from the Arctic Ocean takes place.

A Synthesis of the Upper Arctic Ocean Circulation During 2000–2019: Understanding the Roles of Wind Forcing and Sea Ice Decline

Frontiers in Marine Science, 2022
Major changes have occurred in the Arctic Ocean during 2000–2019, including the unprecedented spin-up of the Beaufort Gyre and the emergence of Arctic Atlantification in the eastern Eurasian Basin.

Disentangling the Coupled Atmosphere‐Ocean‐Ice Interactions Driving Arctic Sea Ice Response to CO2 Increases

Journal of Advances in Modeling Earth Systems, 2020
A novel decomposition of the ocean heat energy that contributes to sea ice melt and growth (ocean‐ice and frazil heat) into components that are driven by surface heat flux and ocean circulation changes is used to isolate the evolving roles of the ...

A model study of the first ventilated regime of the Arctic Ocean during the early Miocene [PDF]

Polar Research, 2012
The tectonic opening of Fram Strait during the Neogene was a significant geological event that transferred the Arctic Ocean from a poorly ventilated enclosed basin, with weak exchange with the North Atlantic, to a fully ventilated “ocean stage ...
