PARAMETERS COMPARSION OF LEADS DETECTION IN ARCTIC SEA ICE USING CRYOSAT-2 WAVEFORM DATA
Arctic, Sea ice, Lead, Satellite altimetry
2018/5/14
Leads are only a small part of the polar sea ice structure, but they play a dominant role on the turbulence exchange between the ocean and the atmosphere, they are also important factors about sea ice...
Hovercraft as a Mobile Science Platform Over Sea Ice in the Arctic Ocean
Arctic Ocean Science Platform Over Sea Ice
2015/7/17
Physical sampling of sea ice, the water mass, and subbottom geology in the Arctic Ocean is carried out from icebreakers or temporary ice camps deployed and supported by aircraft. Here, we consider an ...
Light and nutrient control of photosynthesis in natural phytoplankton populations from the Chukchi and Beaufort seas, Arctic Ocean
Light nutrient control of photosynthesis
2014/4/2
During the 2010–2011 ‘Impacts of Climate Change on the EcoSystems and Chemistry of the Arctic Pacific
Environment’ project, we measured photosynthetic parameters in natural Arctic phytoplankton assem...
On the existence of stable seasonally varying Arctic sea ice
existence stable seasonally varying Arctic sea ice
2012/2/28
Within the framework lower order thermodynamic theories for the climatic evolution of Arctic sea ice we isolate the conditions required for the existence of stable seasonally-varying ice states. This ...
A Numerical Investigation of Arctic Ocean Dynamics
Numerical Investigation Arctic Ocean Dynamics
2009/4/2
A barotropic numerical model of the Arctic Ocean is formulated to include irregular basin shape, variable bathymetry, lateral friction, bottom drag, and nonlinear advection terms. Source-sink distribu...
Numerical Simulation of the Arctic Ocean Circulation
Numerical Simulation Arctic Ocean Circulation
2009/3/7
The circulation of the Arctic Ocean and Greenland Sea is simulated using the 1969 numerical model of Bryan and Cox. The coastline and bottom topography of the region are resolved by a 110 km horizonta...
Measurements made in Cambridge Bay, N.W.T., during the winter show that the breaking of internal waves on the shore influences downward salt transport from the homogeneous surface layer produced by sa...
The Horizontal Coherency of the Motion of Summer Arctic Sea Ice
Horizontal Coherency Summer Arctic Sea Ice
2009/2/18
Four ice floes in the permanent arctic ice pack were instrumented during the summer of 1975. Spectral and cross-spectral analysis of the complex time series of the ice motion and of the surface winds ...
A Study of Oceanic Boundary-Layer Characteristics Including Inertial Oscillation at Three Drifting Stations In the Arctic Ocean
Oceanic Boundary-Layer Characteristics Inertial Oscillation Three Drifting Stations the Arctic Ocean
2009/2/16
Measurements of surface drift and near-surface currents taken during August 1975, at drifting ice stations of the AIDJEX experiment in the central Arctic, are used to infer the response of the upper o...
An Analysis of Arctic Sea Ice Fluctuations, 1953–77
Arctic Sea Ice Fluctuations polar cap digitized data
2009/2/13
Arctic sea ice data from the 1953–77 period are digitized onto a set of 300 monthly grids covering the polar cap. Each grid contains 1648 ice concentration points at a spacing of 1° latitude (60 n mi)...
Model for the Thickness and Salinity of the Upper Layer in the Arctic Ocean and the Relationship between the Ice Thickness and Some External Parameters
Upper Layer Arctic Ocean Ice Thickness External Parameters
2009/2/10
This paper presents a dynamical model for the salinity and thickness of the upper layer in the Arctic. The parameters are the river runoff to the Arctic, the buoyancy supply through the Bering Strait,...

Internal Waves Arctic Ocean Lower-Latitude Observations
2009/1/15
A thermistor chain was moored below the pack ice from 50–150 m in the Arctic Ocean for five days in 1981. Oscillations in temperature are attributed to the vertical dispalcement of internal waves. The...
