Artifacts recovered after long immersion in salt or freshwater require conservation treatment if they are to last. On exposure to high concentrations of oxygen in the air, iron artifacts will bloom into piles of rust. Wood will crack and split if dried out improperly. Organic materials will crumble to dust.
The manual below details conservation methods for many types of materials and artifacts.
Nerodia sipedon
Size: to 42"
Habitat: in and around water
Notes: Not poisonous, but likely to bite if caught, with sharp, needle-like teeth. These snakes retreat into the water at the slightest disturbance, and are excellent swimmers, although they show no particular adaptations to it like oceanic sea snakes. Common small harmless Garter snakes are also often found around water. Most sport some variation of an attractive pattern of yellow/black stripes.
