Here is a similar story
Not so warm in 400 year may the report been named today but since this article is some year old is it still science involved.
“Entombed Plant Communities Released by a Retreating Glacier
at Central Ellesmere Island, Canada”
http://pubs.aina.ucalgary.ca/arctic/Arctic37-1-49.pdf

FROM THE ABSTRACT ” The release of a dead but well-preserved high Arctic plant community, entombed for about 400 radiocarbon years (WAT-778 and 789)
under glacial ice at Twin Glacier, central Ellesmere Island (78″53′N7,5 35%)’ is reported. Remarkably intact plants have been emerging from under
the ablating front of this polar glacier which has been retreating for several decades”

In short: the glaciar advanced in the beginning of little ace age and covered plants that now are found quite well preserved.

Why not go for it big style?
Warmest period in 100.000 year
http://www.glaciology.gfy.ku.dk/papers/pdfs/201.pdf
And
http://www.gfy.ku.dk/~www-glac/ngrip/presse_070804_eng.html
And Yes it was warmer than today before that.
“…at least a 5 K warmer temperature in the
Eemian than at present..”

Have not been found the dating of this remnants of plants.

Re: raytoster (#45), Here you are.

In April of 1997 a 121 m deep ice core was retrieved from Lomonosovfonna, the highest ice field at Svalbard (1250 m asl) (Fig. 1; Table 1). Radar measurements at the core site suggested that the bedrock would have been reached within 5 m.

Re: raytoster (#45), IIRC, you can't use the data from the bottom of a moving glacier. Plastic flow starts to scramble the layers at some point.

Re. Phil # 34.

I think what MangoChutney was alluding to was if the study was of a 800 year period because that was the total lenght of ice core available, meaning the ice glacier didn’t exist before 800 years ago. Then what he said was logically correct.

Phil, do you know if they reached the bottom of the glacier with the ice core. This has important implications.

A question,

We saw in 2007 that changing wind patterns dramatically affected the ice extent in the Arctic. Would these patterns therefore not have some effect on ice cores taken in the future?

If so, how can we quantify what effect changing wind patterns might have had in the past?

Re: Phil. (#34), Phil, Accepted, my extrapolation was clearly not supported by the information provided
