  1. Could do well to do some cross-disciplinary comms with survey methodologists, seems like. There's a rich formality for coding synthesis available to tap into.

    "Massive corals build their skeletons in annual layers, like tree rings, which are used to study how their growth responds to environmental changes in the ocean. Identifying the start and end of each annual layer is not always straightforward, and individuals may place the boundaries of annual layers at different positions when assessing the same coral core. In this study, 12 people independently identified growth layers in 10 coral skeletons from Dongsha Atoll. We found that estimates of how much the corals grew each year could vary widely depending on who did the band placements, and which coral sample was used. However, when we combined results from multiple people and coral samples, the growth patterns became more consistent and reflected ocean climate patterns more consistently. These findings show that using multiple observers and samples is important for generating more reliable records of past ocean conditions from corals."
