Update guidance to version 2.1.1

[jaxinewolfe]

Carry over changes from v1 to v2 database update and add columns which are created during the post processing step.

• rename or delete attribute names where applicable
• habitat will be included in the cores and species table
• quality codes in the cores table
• country and admin_division in the cores table

Knit-picky notes, tasks, and questions

• species spelling should be resolved at the curation level. Post-synthesis, the taxa database should be updated if necessary and there should be a lookup table (perhaps another col in the database) which equates species to different habitats. This is & will be a manual assignment.
  • should we create/maintain a species-to-habitat lookup table? (or genus level)?
• Habitat assignments
  • should we look at satellite imagery for hotspot sites? or crossref with the CCAP?
  • from the species table (assigned in hook script via our species-assigned-habitat lookup table) is used to inform core-level habitat. should this be part of the post-processing step?
  • use the Cowardin et al 1979 wetland classification scheme for our database?
• Holmquist synthesis: Nyman et al 1993 salinity class misspelled => “brackish to saline (theres a lot of uncontrolled vars in this synth)
• dated cores => resolve the Plum model stuff
• year and month have two different definitions within the CCN database
• age
  • age values range from 5818 (Drexler 2009) to -47 (Krauss 2018), there’s a mix of calendar year and year values
• marker date…is it numeric (real v integer) or date?
• Will CRS age depth model always use mass accumulation as the rate?
• should we include detector limits for radioisotopes? could be different for each…
• I’m confused about how we indicate sample age…is it age like 150 years? Or age like a date 1871?) (Ex. Eagle study)
