# talk_*.dat (Files 10-14)

These files provide the interpolated TALK fields calculated annually and for each quarter (talk_ann.dat, talk_djf.dat, talk_mam.dat, talk_jja.dat, and talk_son.dat). The files are sorted by longitude and latitude and can be read by using the following FORTRAN 77 code [contained in talkdat.for (File 5)]:

REAL lon, lat, dep, mld, talk, tmp, sal, coefa, coefb REAL coefc read (1, 10, end=999) lon, lat, dep, mld, talk, tmp, 1 sal, coefa, coefb, coefc 10 format (F7.1, 1X, F6.1, 1X, F7.1, 1X, F7.1, 1X, F9.1, 1 1X, F7.3, 1X, F7.3, 1X, F10.3, 1X, F10.3, 1X, F10.3)

Stated in tabular form, the contents include the following:

Variable | Variable type | Variable width | Starting column | Ending column |
---|---|---|---|---|

lon | Numeric | 7 | 1 | 8 |

lat | Numeric | 6 | 9 | 16 |

dep | Numeric | 7 | 16 | 25 |

mld | Numeric | 7 | 24 | 34 |

talk | Numeric | 9 | 32 | 43 |

tmp | Numeric | 7 | 42 | 52 |

sal | Numeric | 7 | 50 | 61 |

coefa | Numeric | 10 | 58 | 70 |

coefb | Numeric | 10 | 69 | 79 |

coefc | Numeric | 10 | 80 | 88 |

The variables are defined as follows:

lon | - | is the longitude for which TALK was calculated; |

lat | - | is the latitude for which TALK was calculated; |

dep | - | is the depth for which TALK was calculated (m); |

mld | - | is the maximum layer depth (m); |

talk | - | is the total alkalinity (µmol/kg); |

tmp | - | is the temperature (°C); |

sal | - | is the salinity; |

coefa | - | is the a coefficient (offset); |

coefb | - | is the b coefficient to temperature; and |

coefc | - | is the c coefficient to salinity. |
