Observation of Sea Ice Thickness using a Shipborne Electromagnetic-inductive Sensor

The Development of Sea Ice Thickness Measurement Sensor

This paper reports on the development of an acoustic sea ice thickness measurement sensor. The development is applying acoustic NonDestructive-Testing (NDT) techniques to test first year sea ice including significant amounts of enclosed air bubbles. Two single piezoelectric transducers are tightly placed on smoothed sea ice surface to emit and receive acoustic signals. Besides seeing a detectab...

Modeling sea ice thickness

In this paper, we present a self contained review on the modeling of sea ice thickness distribution. This is an important quantity arising and contributing to global climate changes. We present the various pde describing it, which are strongly non linear. Detailed mathematical analysis will be reported elsewhere. The utility of this quantity is of course to set up a global analysis of sea, ice ...

Sea-Ice Thickness Measurement:

Helicopter-borne electromagnetic (HEM) induction systems provide a means to measure sea ice thickness along flight paths covering a large area in a short period of time, and make the data available in real-time for incorporation into operational ice charts. Ice surface elevation profiles are also collected with a laser altimeter contained in the system. With the introduction of the fix-mounted ...

Theory of the Sea Ice Thickness Distribution.

We use concepts from statistical physics to transform the original evolution equation for the sea ice thickness distribution g(h) from Thorndike et al. into a Fokker-Planck-like conservation law. The steady solution is g(h)=N(q)h(q)e(-h/H), where q and H are expressible in terms of moments over the transition probabilities between thickness categories. The solution exhibits the functional form ...
