Abstract The Arctic Ocean is facing dramatic environmental and ecosystem changes. In this
context, an international multiship survey project was undertaken in 2020 to obtain current …

Atlantic Water (AW) is the largest reservoir of heat in the Arctic Ocean, isolated from the
surface and sea ice by a strong halocline. In recent years, AW shoaling and warming are …

The silicon isotope composition of silicic acid, δ30Si (OH) 4, in the deep Arctic Ocean is
anomalously heavy compared to all other deep ocean basins. To further evaluate the …

The interannual variability in fluorescent dissolved organic matter (FDOM) was assessed in
the Pacific‐and Atlantic‐derived halocline, and Atlantic waters (AWs) of the Canada Basin …

Abstract In the Canada Basin of the Arctic Ocean, warm and salty Atlantic‐origin Water (AW)
lies in the intermediate layer (250–800 m) below a colder and fresher surface layer. It results …

The intrusion of the warm and saline Atlantic Water (AW) has significant implications and
feedback on the dynamics and thermodynamics of the Arctic Ocean. The AW enters the …

Using long‐term moorings data together with wind and sea ice measurements, we
document the characteristics and variations of upwelling in Barrow Canyon and investigate …

Anthropogenic radionuclides 129I and 236U are used to investigate pathways of the Atlantic
Water flow in the Canada Basin, estimate transport timescales, and investigate mixing …

Halocline eddies transport mass and energy across the Arctic Ocean. Seismic
oceanography uses multichannel seismic reflection (MCS) data to create high resolution …

In this contribution, we present tritium‐3He (3H‐3He) apparent ages and hydrographic data
from 21 expeditions spanning 27 years of Arctic Ocean section work (1987–2013) to …
