δ13C records from the mid-depth Atlantic show a pronounced decrease during Heinrich Stadial 1 (HS1), deglacial episode of dramatically weakened Meridional Ocean Circulation (AMOC). Proposed explanations for this include greater fraction δ13C-depleted southern sourced water (SSW), in North Deep Water (NADW) end-member, and accumulation respired organic carbon. However, relative importance these ...

Remote sensing images contain a lot of mixed image pixels, but it is difficult to classify these pixels. If the number of pixel’s end-member is regarded as unchangeable, the traditional pixel unmixing algorithm cannot get a good result. In this paper we develop a new method of selective end-members for pixel unmixing based on the fuzzy ARTMAP neural network, which firstly compares the pixel’s s...
