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:
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 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.
- 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).- The date of the cast in MMDDYY.
- The time taken at the beginning (BE), bottom (BO), and completion
(EN) of the cast.
- 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.
- Depth meassured by shipboard echo sounder in meters. The nominal
depth for Station 1 = 1500m and for Station 2 = 4750m.
- Bottom depth less the maximum pressure sampled.
- The deepest pressure sampled.
- The number of bottles used during the cast.
- 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- Cast comments.
