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 ...
متن کاملSea-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 ...
متن کاملRetrieval of sea-ice thickness distribution in the Sea of Okhotsk from ALOS/PALSAR backscatter data
Although satellite data are useful for obtaining ice-thickness distribution for perennial sea ice or in stable thin-sea-ice areas, they are still largely an unresolved issue for the seasonal ice zone (SIZ). We address this problem using L-band synthetic aperture radar (SAR). In the SIZ, ice-thickness growth is closely related to deformation, so surface roughness is expected to correlate with ic...
متن کاملA sea-ice thickness retrieval model for 1.4 GHz radiometry and application to airborne measurements over low salinity sea-ice
In preparation for the European Space Agency’s (ESA) Soil Moisture and Ocean Salinity (SMOS) mission, we investigated the potential of L-band (1.4 GHz) radiometry to measure sea-ice thickness. Sea-ice brightness temperature was measured at 1.4 GHz and ice thickness was measured along nearly coincident flight tracks during the SMOS Sea-Ice campaign in the Bay of Bothnia in March 2007. A research...
متن کاملTheory 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 ...
