Contextual Documentation

When the 1622 wreck of the Atocha was discovered off the Florida coast, the team had to map every single coin and timber before moving them. If they had simply grabbed the gold and left, the story of how the ship broke apart would have vanished forever. This is the essence of contextual documentation, a process that captures the exact spatial relationship of every object to its surroundings. Without this record, an artifact is just a lonely object stripped of its historical identity. Archaeology is not about finding lost treasures, but about reconstructing the lives of people through the items they left behind in the mud.

The Logic of Site Mapping

Recording a site requires the same precision as a crime scene investigator documenting evidence before it disappears. We use a grid system to divide the underwater site into manageable squares, which helps us track exactly where each piece sits. Imagine trying to reassemble a complex puzzle after someone has shuffled all the pieces into a pile. By assigning a specific coordinate to every fragment, we ensure that we can digitally rebuild the site later. This method allows us to see patterns, such as where heavy cargo settled versus lighter personal belongings, which reveals the final moments of the vessel.

Key term: Provenance — the documented history and exact original location of an artifact, which confirms its authenticity and historical value.

When we document a site, we must focus on three primary data categories to ensure that future researchers can understand our findings without needing to be there themselves:

• Spatial data provides the precise three-dimensional location of an object, allowing us to map its position relative to other items on the seabed.
• Descriptive logs capture the physical state, material, and dimensions of an artifact, which helps identify its purpose and origin within the ship.
• Photographic records create a visual archive of the site before any disturbance occurs, providing a permanent reference for the original condition of the debris.

Maintaining Scientific Integrity

Documentation acts as the primary defense against the loss of historical information during the excavation process. Because water hides the site from view, we rely on these records to act as our eyes during the post-excavation analysis phase. Every measurement we take serves as a permanent anchor for the site history, ensuring that we do not lose vital context. If we fail to record the depth or orientation of a timber, we lose the ability to determine if the ship hit a reef or suffered from a structural failure. This scientific rigor separates professional archaeology from simple treasure hunting, as our goal is to preserve knowledge for future generations.

We must also account for the environmental factors that influence site formation over many centuries. Currents, marine life, and shifting sands constantly move objects, so we document the seafloor conditions alongside the artifacts themselves. This creates a complete narrative of the site, showing how nature has interacted with the human remains over time. By combining these environmental notes with our artifact data, we build a comprehensive model of the wreck. This is the application of site recording principles from Station 10, ensuring that every recovered item maintains its historical link to the larger vessel.

Accurate documentation preserves the historical story of an artifact by recording its exact location and relationship to its environment.

But this manual recording process becomes incredibly difficult when we move into deeper waters where human divers cannot safely operate.
