DensityAndBubbles

=Density measurements and bubble pictures in McMurdo= We also took 20-30 cm long surface samples to measure density and to take pictures of thick sections once back in McMurdo (as in December samples). The densities are in the file and the overview of densities is shown in Figure 5. The photos that we took of thick sections of these "density cores" can be found [|here]; the image center is magnified (image size 21 x 32 mm). The scale of the images is marked with 5 cent "nickel" coins. The diameter is 21.21 mm. The pictures are in ascending order from core 24 to core 38 (even numbers of cores). One image shows the complete core (89 mm diameter), the other is a magnified part from the center of the image.
