This function converts a CTD hexadecimal (.hex) file to bathythermic data (.btd) and bathythermic header files (.bth). If you are unable to convert your file, please contact sean.rohan@noaa.gov.

Usage

convert_ctd_btd(
  filepath_hex,
  dirpath_output = "./",
  filepath_xmlcon = NULL,
  latitude = NA,
  VESSEL = NA,
  CRUISE = NA,
  HAUL = NA,
  MODEL_NUMBER = NA,
  VERSION_NUMBER = NA,
  SERIAL_NUMBER = NA,
  instrument_timezone = "America/Anchorage",
  filename_add = "new"
)

Arguments

filepath_hex

Required. Filepath to the SBE19plus hexadecimal (.hex) file from a single cast as a character vector (e.g. "C:/CTD/202301_162_L1/sbe19plus01908091_05_04_0001.hex")/.

dirpath_output

Optional. The default is the local working directory but may be specified with a string.

filepath_xmlcon

Required. Filepath to the instrument configuration file (.xmlcon) for the CTD (e.g. serial number 8091 would use the file with 8091 in the name ("C:/CTD/xmlcon configuration files/SBE19plusV2_8091.xmlcon").

latitude

Required. Latitude in decimal degrees (approximate).

VESSEL

Required. The vessel number (e.g., 94).

CRUISE

Required. The cruise number (e.g., 201901).

HAUL

Required. The haul number (e.g. 150).

MODEL_NUMBER

Optional. The model number of the CTD .

VERSION_NUMBER

Optional. The version number of the CTD.

SERIAL_NUMBER

Optional. The serial number of the CTD.

instrument_timezone

Time zone for the instrument data. Do not change unless the instrument is not setup for Alaska Time

filename_add

Optional. Default = "new". This string will be added to BTD and BTH outputs. This can help prevent accidentally overwriting BTH and BTD files.

Value

.BTH and .BTD files to the dirpath_output directory.
