The data were received at NGDC via NODC on August 19, 1997. Additional data codes and documentation are in poor, extremely hard to read condition. Some parts of the documentation are available below, some in the .pdf file referenced above. There are known problems in these data files, including truncation of records past the 80th column in the first file (Benthic Sediment Characteristics). Other problems exist in device codes and analyses that were unable to be resolved by multiple exchanges with the contributor. Other problems not mentioned may exist in the data, including variations from the specified formats. AVAILABILITY Data are available at no charge from the NGDC Web site.
