Environmental Data Meeting Part 3
Yesterday’s meeting notes
In the third installment of our “what does all of this actually mean” meetings, Micah, Alex, Emma, Brent, Laura, Steven and I discussed the progress we’ve made integrating all of our data into one cohesive story.
Notes:
- Dissolved oxygen measurements
- FB most eelgrass dominated, higher pH, could have daily super saturation (DO > 12)
- Need to do literature survey to verify measurements are “real”
- Padilla Bay: DO ~ 19.3 max for sensors that never come out of the water
- FB most eelgrass dominated, higher pH, could have daily super saturation (DO > 12)
- Should clip DO, pH and salinity data
- Conservative one hour/one foot clipping
- Use Union for SK tidal data
- Just use bare for all sites
- Correcting values to the right mean salinity from sensors can be difficult, lead to discrepancies
- End drops in salinity and pH could be burials
- Can examine brief window of environmental data one or two days before sampling
- Number of low tides could be interesting
- ex. Lots of drops in salinity at WB –> could number of low tides affect protein expression?
- Eelgrass extent as an explanatory variable
- Global eelgrass effect could override any bare sites?
- Biomarker data
- Ignore fatty acid data for now since there’s a low sample size
- Final height is a proxy for growth
- FB grew the most, CI grew the least
- Tissue mass highest in FB, then PG. WB, SK, and CI were similar
Next steps:
- Figure out biomarker comparison table code
- Scrub data
- Make environmental variable table
- Average
- Median
- Maximum
- Minimum
- Standard deviation/variance
- Number of observations above/below SD/2 SDs
- Number of exposures/low tides
- Days exposed
- Total time exposed
