Welcome to the HOT Data Base

Cruises are made to the HOT deep water station approximately
once a month, and are denoted as HOT-n, where n is the
sequential cruise number. HOT-1 was in October 1988.

Station inventories are given in files with the extension "sum" (e.g.,
HOT-1 is summarized in hot1.sum).

Station inventories from the ALOHA-Climax (AC) cruises are summarized
in files with the prefix ac (e.g., AC-1 is summarized in ac1.sum).

These summary files are written using formats specified by the WOCE
Hydrographic Programme Office, and are detailed in the WHP Office
Report WHPO 90-1, available from Steve Diggs, WHPO Data Manager,
Scripps Institution of Oceanography, 9500 Gilman Drive, La Jolla, CA
92093-0214.

The station summary file contains the following columns:

Country Code-Ship Code-Expedition Designation / Leg (EXPOCODE):
  This code allows for the indentification of cast.  It consists
  of a 4 character NODC country-ship code, a maximum of 8 charac-
  ter cruise number followed by a "/" and leg number.  For example,
  the EXPOCODE for HOT-13 on the Moana Wave would be 31MW013/1.
  
WHP-ID:
  The WHP section designator.
  
Station number

Cast number and type:
  The cast type is a three letter description (i.e., ROS =
  Rosette water samples plus CTD; CTD = CTD only, LVS = large
  volume samples).
  
Date:
  The date of the cast in MMDDYY.
  
Time:
  The time taken at the beginning (BE), bottom (BO), and completion
  (EN) of the cast.
  
Position:
  Positions are recorded as (D)DD MM.MM X, where X is N or S for
  latitude and E or W for longitude.  The navigation system code has
  been set to GPS.
  
Bottom depth:
  Depth meassured by shipboard echo sounder in meters.  The nominal
depth for Station 1 = 1500m and for Station 2 = 4750m.
  
Height above bottom:
  Bottom depth less the maximum pressure sampled.
  
Maximum pressure:
  The deepest pressure sampled.
  
Number of bottles:
  The number of bottles used during the cast.
  
Parameters:
  A list of the parameters measured from the water samples collected
  during the cast.  The identification numbers are listed below.
  
  	1 = Salinity
	2 = Oxygen
	3 = Silicate
	4 = Nitrate
	5 = Nitrite
	6 = Phosphate
	7 = Freon 11
	8 = Freon 12
	9 = Tritium
	10= Helium
	11= Carbon 14
	12= Carbon 13
	13= Krypton 85
	14= Argon
	15= Argon 39
	16= Neon
	17= Radium
	18= Radium 226
	19= o18/o16 ratio
	20= Stronitum 90
	21= Cesium 137
