Description

Prochlorococcus in situ growth rates from cell cycle analysis.

These data were published in:

Hynes et al., 2015

Rhodes, 2019.

McDuff & Chrisholm, 1982

Methods & Sampling

Prochlorococcus growth rates were calculated from diel time courses of the cell cycle phase fractions in data set ProCellCyclePhase from this project, as described in McDuff & Chisholm (1982) and modified by Liu et al. (1997). These calculations require an estimate of Td, the duration of the terminal cell cycle phase (in this case the combined duration of S and G2). Td is derived here using the areal median of the S and G2 time series (Braunwarth and Sommer 1985) as recommended by Hynes et al. (2015).

Data Processing Description

BCO-DMO Data Processing Notes:

- separated dateTime columns from Time.Start.UTC and Time.End.UTC to date_start_UTC and time_start_UTC and date_end_UTC and time_end_UTC (created 2 new columns)
- replaced all decimal points in column names with underscores
- reformatted date from mm/dd/yy to yyyy/mm/dd and time from AM/PM to 24hr time
- added ISO_DateTime_UTC column
