The cross-section reveals a narrative written in cambium -- each ring a year's testimony of rainfall, drought, fire, and stillness. The wider bands of the 8th century correspond to the Medieval Warm Period; the compressed lines of the 14th mark the onset of the Little Ice Age. Station EESUGI's spectral analysis has identified 47 distinct chemical signatures within the heartwood, each a timestamp of atmospheric composition now lost to history.

NON-INVASIVE SCANNING

The EESUGI station employs a proprietary holographic scanning array that captures cellular-level detail without physical contact. Each specimen is mapped through 14,400 individual scan passes over a 72-hour acquisition window. The resulting point cloud contains approximately 2.3 billion vertices per specimen, rendering the internal ring structure with sub-millimeter accuracy.

SPECTRAL ANALYSIS

Chemical composition of each ring is determined via non-destructive spectroscopy. Carbon isotope ratios (delta-13C) and oxygen isotope ratios (delta-18O) provide proxy records of temperature and precipitation for each growth year. Heavy metal traces in outer rings document industrial atmospheric changes beginning in the Meiji period.

ARCHIVAL ENCODING

Completed scans are encoded into the EESUGI Dendro Archive format (.eda), a lossless three-dimensional representation that preserves spatial relationships between rings, ray parenchyma, and resin canals. Each archive record is cryptographically timestamped and distributed across seven geographically separated cold-storage facilities.
