In tomhull/airsea: Tools for air/sea gas exchange
The airsea R package
What is this repository for?
- Tools for marine air-sea gas exchange studies.
- Version 0.1
What can the package do?
- Calculate water-side and air-side gas transfer velocity using a range of modern parametisations.
- Calculate Schmit numbers for (almost) any gas
- Calculate bubble supersaturation effects (bubble induced equilibrium concentration)
- Calculate net community production from in-situ oxygen observations (also known as open water metabolism).
- Calculate various seawater properies, density, viscosity...
airsea and marelac
marelac and airsea have some similar features with differing implementation:
- Schmit number calculation, however marelac assumes 35 salinity, airsea has more gasses.
- Gas saturation concentration, airsea only includes O2 based on Benson and Krause. marelac uses Weiss for several gases and includes pressure compensation.
Gasses in marelac gas_schmit but not in airsea
- Helium (He)
- Sulfur hexafluoride (SF6)
- Trichlorofluoromethane (CCl3F)
- Dichlorodifluoromethane (CCl2f2)
TODO
- explore marelac vs liang solubility
- fully implement liang2013 bubble and kw
Installation
