skeleton_weight: Compute the skeleton weight with the buoyant weight

In EcoNum/seal.econum: Conversion, correction et analyse des données provenant du seal AA3 d'ECONUM

Description

The buoyant weight is a simply tools. This method reduces the stress during the manipulation of the coral's nubbins. The buoyant weight is used to calculate the skeleton weight. The evolution of skeleton weight can bu used to monitor the growth of the coral's nubbins.

Usage

skeleton_weight(buoyant_weight, S, T, P = 0, rho_aragonite = 2930)

rho(S = 35, T = 25, P = 0)

Arguments

buoyant_weight	buoyant weight in gramme
S	salinity in PSU
T	temperature in degree Celsius
P	hydrostatic pressure in bar
rho_aragonite	density of the aragonite

Value

skeleton weight

Note

[rho()] is borrowed from [seacarb::rho()], but its code is copied here because do *not* want to import **seacarb** that itself depends on **oce** and **gsw** that bring a lot of useless additional dependencies!

Examples

skeleton_weight(buoyant_weight = 25, S = 35, T = 25, P = 0, rho_aragonite = 2930)

# second example on a dataset , growth
data(growth) # load data
growth$skeleton_weight <- skeleton_weight(buoyant_weight = growth$weight,
S = growth$salinity, T = growth$temperature, P = 0, rho_aragonite = 2930) # compute new variable
growth$skeleton_weight # see the new variable
