Great timing. I read and article on this in New Scientist during the WT study yesterday and was going to post a topic on the subject of ice cores and flood. I too searched for "ice cores" on the WT Library and found no trace of any mention of them except for one...
It's a picture credit from page 10 of the Was Life Created brochure where they use the picture of some bacteria that were found in 3km deep in an ice core taken from a glacier in Greenland with an age of 120,000 years . You can see the same picture and read more about this here:

The full credit is:
Penn State University, laboratory of Jean Brenchley, and with kind permission from Springer ScienceBusiness Media: Extremophiles, Novel ultramicrobacterial isolates from a deep Greenland ice core represent a proposed new species, Chryseobacterium greenlandense sp. nov., January 2010, Jennifer Loveland-Curtze;
They refer to the picture as "subterranean bacteria". In the text they state the following:
Earth: Just one hundred grams (3.5 ounces) of soil has been found to host 10,000 species of bacteria, not to mention the total number of microbes. Some species have been found almost two miles underground!
The last sentence is referenced to this article in the bibliography:

The synopsis is:
DNA from low-biodiversity fracture water collected at 2.8-kilometer depth in a South African gold mine was sequenced and assembled into a single, complete genome. This bacterium, Candidatus Desulforudis audaxviator, composes >99.9% of the microorganisms inhabiting the fluid phase of this particular fracture. Its genome indicates a motile, sporulating, sulfate-reducing, chemoautotrophic thermophile that can fix its own nitrogen and carbon by using machinery shared with archaea. Candidatus Desulforudis audaxviator is capable of an independent life-style well suited to long-term isolation from the photosphere deep within Earth’s crust and offers an example of a natural ecosystem that appears to have its biological component entirely encoded within a single genome.
So the "subterranean" bacteria is not just from under the earth, but from ice that has been there for 120,000 years. And the organisation is implicitly admitting it.
So, you can ask any Witness if the polar ice caps were there before the flood and they will almost certainly say "no" because they all think the climate was in equilibrium earth wide due to the rain canopy. This suggests something different and it's from right out of a publication.
