In situ observation data set of physical parameters of Arctic sea ice in summer of 2008-2018
Listed in ScienceDB
With the global warming, the Arctic summer sea ice also has experienced a series of changes.
Description
For example, the sea ice extent and thickness are reduced. Temperature, salinity and density are the basic physical parameters of sea ice.
It is difficult to use remote sensing technique to conduct large-scale observations, but need field measurements. This data is the observations of physical properties of Arctic sea ice during the summers of 2008-2018. The observation sites are located in the Pacific sector of the Arctic Ocean.

The data files contain specific information of each ice station, ice temperature profiles (2008-2016), salinity profiles (2008-2018), density profiles (2008-2018) and crystal structure profiles (2012-2018). The ice temperature is measured by a probe temperature sensor. The ice salinity data is obtained by measuring the melt water of ice sections with a salinometer.
The density data is obtained using mass/volume method. The ice crystal structure is obtained by observing ice slices under crossed polarized light. The data has a wide application.
It can be used to verify the simulation results of sea ice models, and also to evaluate the phase composition contents and thermodynamic properties of the Arctic summer sea ice.
