Ocean tide influences on the Antarctic and Greenland ice sheets

L Padman, MR Siegfried, HA Fricker - Reviews of Geophysics, 2018 - Wiley Online Library
Ocean tides are the main source of high‐frequency variability in the vertical and horizontal
motion of ice sheets near their marine margins. Floating ice shelves, which occupy about …

Impact of wind-driven mixing in the Arctic Ocean

L Rainville, CM Lee, RA Woodgate - Oceanography, 2011 - JSTOR
ABSTRACT The Arctic Ocean traditionally has been described as an ocean with low
variability and weak turbulence levels. Many years of observations from ice camps and ice …

Greater role for Atlantic inflows on sea-ice loss in the Eurasian Basin of the Arctic Ocean

IV Polyakov, AV Pnyushkov, MB Alkire, IM Ashik… - Science, 2017 - science.org
Arctic sea-ice loss is a leading indicator of climate change and can be attributed, in large
part, to atmospheric forcing. Here, we show that recent ice reductions, weakening of the …

Weakening of cold halocline layer exposes sea ice to oceanic heat in the eastern Arctic Ocean

IV Polyakov, TP Rippeth, I Fer, MB Alkire… - Journal of …, 2020 - journals.ametsoc.org
A 15-yr duration record of mooring observations from the eastern (> 70° E) Eurasian Basin
(EB) of the Arctic Ocean is used to show and quantify the recently increased oceanic heat …

Toward quantifying the increasing role of oceanic heat in sea ice loss in the new Arctic

E Carmack, I Polyakov, L Padman, I Fer… - Bulletin of the …, 2015 - journals.ametsoc.org
The loss of Arctic sea ice has emerged as a leading signal of global warming. This, together
with acknowledged impacts on other components of the Earth system, has led to the term …

Arctic Ocean warming contributes to reduced polar ice cap

IV Polyakov, LA Timokhov, VA Alexeev… - Journal of Physical …, 2010 - journals.ametsoc.org
Abstract Analysis of modern and historical observations demonstrates that the temperature
of the intermediate-depth (150–900 m) Atlantic water (AW) of the Arctic Ocean has increased …

Finescale parameterizations of turbulent dissipation

KL Polzin, JM Toole, RW Schmitt - Journal of physical …, 1995 - journals.ametsoc.org
Fine-and microstructure data from a free fall profiler are analysed to test models that relate
the turbulent dissipation rate (ε) to characteristics of the internal wave field. The data were …

Retreat of the cold halocline layer in the Arctic Ocean

M Steele, T Boyd - Journal of Geophysical Research: Oceans, 1998 - Wiley Online Library
We present a comparison of Arctic Ocean hydrographic data sets from the 1990s, with a
focus on changes in the upper few hundred meters of the Eurasian Basin. The most recent …

Turbulent heat flux in the upper ocean under sea ice

MG McPhee - Journal of Geophysical Research: Oceans, 1992 - Wiley Online Library
Turbulence data from three Arctic drift station experiments demonstrate features of turbulent
heat transfer in the oceanic boundary layer. Time series analysis of several w′ T′ records …
