Site 604, from the uppermost continental rise 100 mi. southeast of Atlantic City, New Jersey, was investigated for diatoms, utilizing the processing methods of Abbott (1978, doi:10.1016/0377-8398(78)90009-9). Most of this assemblage is poorly preserved and appears to be reworked from Miocene and Eocene deposits.
