Guliya Core #2 and Mountain Glacier Flow

Here’s an interesting graphic from lecture notes of Jed Schneider and Kathryn Clapp here showing the flow of ice through a mountain glacier. If this is representative of flow in mountain glaciers, one wonders at what exactly is being recorded in a vertical drill hole away from the summit (such as Guliya Core 2). I’ll […]

I did a quick comparison of the unarchived visual plot in Thompson et al (Science 1997) and compared it to the Yang version, yielding […]

More on Guliya

I wrote recently on the bizarre spaghetti graph from Guliya – where three inconsistent versions have been used in 2006 articles. I think that I may have a good first step at decoding this mess, as illustrated in the comparison below of the PNAS 2006, Climatic Change 2004 and Yang 2002 versions (used again in […]

The Yang Composite is a mainstay of recent Hockey Team reconstructions – its use in Team reconstructions began in Mann and Jones 2003 and was then “randomly selected” into Osborn and […]
