Anomalous collapses of Nares Strait ice arches leads to enhanced export of Arctic sea ice

open access: yesNature Communications, 2021
The ice arches that usually develop at the northern and southern ends of Nares Strait play an important role in modulating the export of Arctic Ocean multi-year sea ice.

Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions

open access: yesNature Communications, 2020
In the central Arctic Ocean the formation of clouds and their properties are sensitive to the availability of cloud condensation nuclei (CCN). The vapors responsible for new particle formation (NPF), potentially leading to CCN, have remained unidentified

Elastic waves in Arctic pack ice

open access: yesEos, Transactions American Geophysical Union, 1954
Elastic wave propagation was studied in the Arctic ice pack, on the Beaufort Sea, the Arctic Ocean, and at near‐shore locations. Ice thicknesses varied from 0.1 to 2.1 meters and water depths from 1 ½ to 3800 meters. Values of the elastic constants were derived from the measured velocities of the longitudinal and shear waves and the density. Dispersive

The Stepwise Reduction of Multiyear Sea Ice Area in the Arctic Ocean Since 1980

open access: yesJournal of Geophysical Research: Oceans, 2023
The loss of multiyear sea ice (MYI) in the Arctic Ocean is a significant change that affects all facets of the Arctic environment. Using a lagrangian ice age product we examine MYI loss and quantify the annual MYI area budget from 1980‐2021 as the ...

Mapping vessel traffic patterns in the ice-covered waters of the Pacific Arctic

open access: yesClimatic Change, 2023
Recent climate change has caused declines in ice coverage which have lengthened the open water season in the Arctic and increased access to resources and shipping routes.

Investigating the vertical extent and short-wave radiative effects of the ice phase in Arctic summertime low-level clouds

open access: yesAtmospheric Chemistry and Physics, 2023
. Low-level (cloud tops below 2 km) mixed-phase clouds are important in amplifying warming in the Arctic region through positive feedback in cloud fraction, water content and phase.

Arctic marginal ice zone interannual variability and change point detection using two definitions (1983–2022)

open access: yesEnvironmental Research Letters, 2023
The ongoing decline in Arctic sea ice extent and thickness underscores the scientific significance of monitoring the marginal ice zone (MIZ), a transitional region between the open ocean and pack ice.

Improving the Met Office's Forecast Ocean Assimilation Model (FOAM) with the assimilation of satellite‐derived sea‐ice thickness data from CryoSat‐2 and SMOS in the Arctic

open access: yesQuarterly Journal of the Royal Meteorological Society, 2022
Derived from two complementary satellites, CryoSat‐2 and Soil Moisture and Ocean Salinity (SMOS), sea ice thickness (SIT) data are assimilated into the Met Office's global ocean–sea ice forecasting system, FOAM, using a 3D‐Var assimilation scheme ...
