Objective: Development of an R / R Shiny platform to investigate historic maritime exploration.

Building upon work focused on models of Polynesian exploration and settlement during pre-colonial times, this R project integrates environmental and paleoenvironmental data from a variety of sources to create an agent-based simulation of maritime exploration. Canoe and navigation strategies comes from historic and indigenous knowledge.

Data Sources

  • Winds – NCEP daily wind data (1948-2020)
  • Currents – OSCAR 1/3 degree current data in 5 day cycle
  • Land – Natural Earth 10m vector
  • Vessels – This sets the leeward drift profile and performance as described by the USCG (2013:440-443) profiles

Radiocarbon Dating Chart

Development of a flexible specialised graph in R (ggplot) for integrating large numbers of radiocarbon dates from Aotearoa New Zealand and Rapa Nui (Easter Island). The graph highlights specific groups of dates (e.g., from a single site) showing the calibration probability curves over a summary of selected range of dates such as from a geographic region. Scaled to a R Shiny application with site location maps.
