Automated Antarctic Ice Edge Detection Tjsing Nsca'i' Data

Polar sea ice plays an important role in the global climate and other geophysical processes. Although spaccborne scatterometers such as NSC.AT have low inherent spatial resolution, resolution enhancement techniques can be utilized to make NSCAT data useful for monitoring sea ice extent in the Antarctic. Dual polarization radar measurements are A and 6: values are used in a linear discrimination...

Environmental correlates of Arctic ice-edge noise

Temporal variations of low-frequency, broadband ambient noise measured in early summer under drifting ice floes of the marginal ice zone (MIZ) are cross correlated with local environmental forces and ice field descriptors. Surface gravity wave forcing is the primary correlate of the noise; its interaction with ice floes generates ound, most likely via flexural floe failure, and unloading motion...

21 Polar and ice-edge marine systems

Cold, seasonal and dominated by ice, the two polar regions are similar in many ways. Oceanographically, however, they are very different. The Arctic is a deep basin surrounded almost completely by extensive shallow continental shelves and continental land masses. Large river systems (Chapter 2) discharge significant volumes of fresh water and sediment into the Arctic basin, some of them carryin...

Data Mining on Ice

In an atmospheric neutrino analysis for IceCube’s 59-string configuration, the impact of detailed feature selection on the performance of machine learning algorithms has been investigated. Feature selection is guided by the principle of maximum relevance and minimum redundancy. A Random Forest was studied as an example of a more complex learner. Benchmarks were obtained using the simpler learne...

Antarctic krill under sea ice: elevated abundance in a narrow band just south of ice edge.

We surveyed Antarctic krill (Euphausia superba) under sea ice using the autonomous underwater vehicle Autosub-2. Krill were concentrated within a band under ice between 1 and 13 kilometers south of the ice edge. Within this band, krill densities were fivefold greater than that of open water. The under-ice environment has long been considered an important habitat for krill, but sampling difficul...
