The adaptation of existing imaging sonars for use on underwater sites will have widespread applicability to the nation’s thousands of submerged archaeological sites located in turbid waters that make detailed archaeological documentation impractical. LCMM has prototyped the feasibility and methodologies for this technology using a Blue View DF900-2250 Dual Frequency Miniature Multibeam Imaging System on sites in Lake Champlain.

This database of micrographs of textile fibers acquired through the use of multiple microscopic techniques contains 145 collections with 1404 individual files, and requires 23GB of storage space. Each file contains a high resolution image with text fields that delineate image location and size, image collection information, microscopy technique and details of the features presented in the image. Micrographs are shown of single fibers and fiber groups examined using brightfield, darkfield, polarized light, and differential interference contrast techniques; the sequences of images provides information complementary to the others.
