Grouping - Tracer ID numbers - plankton number

  • pico - 21:24 - c1 to c4
  • cocco - 25:29 - c5 to c9
  • diazotrophs - 30:34 - c10 to c14
  • diatoms - 35:43 - c15 to c23
  • mixotophic dinoflagellates - 44:51 - c24 to c31
  • zooplankton - 52:67 - c32 to c47
  • heterotrophic bacteria - 68:70 - c48 to c50

All tracer names are in the form "TRAC[ID]" where [ID] is the tracer ID number.
