Improvement of Ice Surface Temperature Retrieval by Integrating Landsat 8/TIRS and Operation IceBridge Observations

open access: yesRemote Sensing, 2023
Accurate retrieval of ice surface temperature (IST) over the Arctic ice-water mixture zone (IWMZ) is significantly essential for monitoring the change of the polar sea ice environment.

Transitions of social-ecological subsistence systems in the Arctic [PDF]

open access: yes, 2017
Transitions of social-ecological systems (SES) expose governance systems to new challenges. This is particularly so in the Arctic where resource systems are increasingly subjected to global warming, industrial development and globalization which ...

Spatial Distribution of Methanesulphonic Acid in the Arctic Aerosol Collected during the Chinese Arctic Research Expedition

open access: yesAtmosphere, 2015
Methanesulphonic acid (MSA, mainly derived from marine biogenic emissions) has been frequently used to estimate the marine biogenic contribution. However, there are few reports on MSA over the Arctic Ocean, especially the central Arctic Ocean.

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.

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 We used meta‐analysis of 23 published and unpublished datasets comprising 721 ice cores to synthesize the variability in

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.

The International Bathymetric Chart of the Arctic Ocean (IBCAO) Version 3.0 [PDF]

open access: yes, 2012
[1] The International Bathymetric Chart of the Arctic Ocean (IBCAO) released its first gridded bathymetric compilation in 1999. The IBCAO bathymetric portrayals have since supported a wide range of Arctic science activities, for example, by providing ...

Hypotheses and tracking results about the longest migration: The case of the arctic tern

open access: yesEcology and Evolution, 2019
The arctic tern Sterna paradisaea completes the longest known annual return migration on Earth, traveling between breeding sites in the northern arctic and temperate regions and survival/molt areas in the Antarctic pack‐ice zone.

Vertical sonar beam width and scanning behavior of wild belugas (Delphinapterus leucas) in West Greenland.

open access: yesPLoS ONE, 2021
Echolocation signals of wild beluga whales (Delphinapterus leucas) were recorded in 2013 using a vertical, linear 16-hydrophone array at two locations in the pack ice of Baffin Bay, West Greenland.

The Best Laid Schemes: A Nares Strait Adventure [PDF]

open access: yesOceanography, 2011
In 2002, oceanographers began a study of Arctic freshwater export via Nares Strait (Münchow et al., 2006). This 550 km channel separating Greenland from Canada is possibly the longest narrow waterway on Earth.
