The board's blustering blunderer recently tried to argue by weblink and provided several YEC sources supposedly "refuting" the dates from counting annual ice layers in core samples. Here is one of them
Do Ice Cores Disprove Recent Creation?
The particular sample they are arguing against is from the The Greenland Ice Sheet Project 2 (GISP2) core samples taken in 1997.
Here are the actual GISP2 results
Notice that each annual layer is determined by at least three and more where applicable of six independent methods.
What do the liars at ICR have to say? First they start bellyaching about indistinct signal the very bottom of the core at 2800m and completely ignore the data with <2% error above 39,850 YPB.
Second they start bellyaching that each annual layer could really be dozens of layer produced by multiple dust storms. This completely ignores that the layer were cross correlated with known volcanic eruptions (besides the other 5 counting methods) providing independent confirmation that the layers are indeed annual.
There you have YEC "science" at its finest. Ignore the actual data, make up lies about the rest, PRAISE JESUS! the world must be really young.
For a great laugh I highly recommend you read the actual GISP2 paper then look at the spin the YECs tried to put on it.

The Greenland Ice Sheet Project 2 depth‐age scale: Methods and results
Meese et al
Journal of Geophysical Research. 102 (C12): 26411–26423 Nov 1997
Abstract: The Greenland Ice Sheet Project 2 (GISP2) depth-age scale is presented based on a multiparameter continuous count approach, to a depth of 2800 m, using a systematic combination of parameters that have never been used to this extent before. The ice at 2800 m is dated at 110,000 years B.P. with an estimated error ranging from 1 to 10% in the top 2500 m of the core and averaging 20% between 2500 and 2800 m. Parameters used to date the core include visual stratigraphy, oxygen isotopic ratios of the ice, electrical conductivity measurements, laser-light scattering from dust, volcanic signals, and major ion chemistry. GISP2 ages for major climatic events agree with independent ages based on varve chronologies, calibrated radiocarbon dates, and other techniques within the combined uncertainties. Good agreement also is obtained with Greenland Ice Core Project ice core dates and with the SPECMAP marine timescale after correlation through the δ18O of O2. Although the core is deformed below 2800 m and the continuity of the record is unclear, we attempted to date this section of the core on the basis of the laser-light scattering of dust in the ice
