Aerial photography was conducted in the high Arctic Ocean during a Chinese research expedition in summer 2010. By partitioning the images into three distinct surface categories (sea ice/ snow, water and melt ponds), the areal fraction of each category, ice concentration and the size and geometry of individual melt ponds, are determined with high-spatial resolution. The ice concentration and mel...

Increasing freshwater input to the subpolar North Atlantic through iceberg melting can influence fjord-scale basin-scale ocean circulation. However, magnitude, timing, and distribution of this have been challenging quantify due minimal direct observations subsurface geometry melt rates. Here we present novel in situ methods capturing change at high-temporal -spatial resolution using four high-p...

We present the results from two independent approaches for monitoring ice-sheet melt area over western Greenland. The microwave-based cross-polarization gradient ratio (XPGR) approach (Abdalati, W. and Steffen, K., 1995, Detecting ice-sheet melt area over western Greenland using MODIS and AMSR-E data for the summer periods of 2002–2006. Geophysical Research Letter, 22, pp. 787–790) is compared ...

Vibrio parahaemolyticus is a leading cause of seafood-borne infections in the US. This organism has a high genetic diversity that complicates identification of strain relatedness and epidemiological investigations. However, sequence-based analysis methods are promising tools for these identifications. In this study, Multi-Locus Sequence Typing (MLST) and Multiple-Locus Variable-Number Tandem-Re...
