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.

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:

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 character 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
