WHOI Mass Spec Data entry, Edited May 2008, DRO

Preparation Field

Within the field are semi-colon (";") separate “tags” that give the user a great deal of flexibility in describing the specimen. You may use any, all or none of the “tags”, as your data requires. We have adopted the convention of describing each “tag” followed by a colon and a “description” as follows:


The tags currently allowable are described in the following section, along with their use. A rule-of-thumb here is lower case tokens indicate system tags whereas upper case tags indicate a user parameter.

a:archive Mostly used for ODP archive vs. working samples
c:comment Multiple comments may be used, up to 256 characters
D:depth Core depth, in meters.
f:size_fraction categorization of the specimen size distribution, usually entered in the forms e.g. 250- 500, <250, >500. Try not to use embedded spaces.
n:count count of number of specimens.
o:operator Initials of the person loading the carousel at WHOI. Identifiers may be
no more than four characters in length. We prefer three characters.
p: identifies the use of pyrite. No string is necessary.
I:information user assigned ID number or string- Note the identifier may contain both letters and numbers, the only constraint being that it may not use semi-colons, colons or commas.
Q:quality a user assigned integer quality value to the specimen. The
Convention is 0:good (default) to 9:very bad.
R:requestor Initials of the person whose samples are in the carousel. Identifiers may be no more than four characters in length. We prefer three characters.
s: identifies sonification. No string is necessary.
u:units is the identifier assigned to describe the units associated with the Core-Depth field which contains the distance taken from the top of the core in centimeters ("cm"). Other two character identifiers could be used, e.g. "m." (meters), "mm", "ft", "in", etc. If the sample was take from a depth of 4 to 6 centimeters the value entry must be constructed as "4-6". The hyphen must be used.
U:units specifies some special units of measurement associated with
the users value of measurement. Length is limited to 16 characters.
V:value_string a user specified value associated with the specimen. The string
may be no longet than 32 characters. The units are as described in the U: token.
X:longitude denotes the decimal degrees of longitude of the position from which the specimen was taken. East of Greenwich is positive and the allowable range is -180 to +180. West is negative.
Y:latitude denotes the decimal degrees of latitude of the position from which the specimen was taken. North of the equator is positive and the allowable range is -90 to +90. South is negative.

Examples of data entry

Core Depth:

Enter the weight for standards ( eg. 94)
Enter the depth (eg. 105)
Enter the depth range (eg. 95-97)


Enter the Cruise-Core


Genus. species

Enter the genus and species (eg. G. ruber-w or N. pachy-L)
Standard information (powder standard)


Many items can be strung together and are separated by a semicolon

for example R:WBC;o:DRO;u:cm;f:125-150;s:;n:10
these are Curry samples loaded by ostermann, depth in cm, fraction 125-150, sonicated, n=10

NOTE: enter the things which may change, like n;10, last in the list for ease of editing

u: units (in core depth) u:cm or u:ft
f: size fraction f:125-150 or f:>250
n: number of specimens n:10
s: sonicated s:
p: pyrite present p:
c: comment c: these were very dirty bugs in general
o: operator o:DRO
R: requestor R:WBC (the PI who is paying)
V: weight (for instance) V:527
U: “V” units U:ug
I: PI supplied ID number or string I:5 or I:PT10039
V: PI supplied weight or other info V:52
U: “V” units U:ug - eg. 52 ug
a: Archive usually used with ODP samples
