ecollectionevents > Exp/Method
This tab includes information about expeditions that produced samples in the collection. Expeditions include both terrestrial and marine programs. For the latter, this tab also includes fields for identifying vessels and cruises.

Expedition Name |
The name of the expedition or field program during which a collecting event took place. Names are typically assigned by the sponsor of an expedition and should use their exact format when possible.
For cruises that are not part of a larger expedition, it can be useful to provide a long-form cruise identifier in this field. For example, leg 2 of cruise ABCD of the Enterprise can be entered as “Enterprise Cruise ABCD (Leg 2)”. This allows the cataloger to include a more readable version of the cruise identifier.

Vessel Name |
The name of the ship from which a sample was collected.
Usage
Omit if no appropriate data is available
Format
If a ship-supported submersible (like Alvin) was used, include both the ship and submersible, separated by a semicolon (“Atlantis II; Alvin”). Omit the prefix “R/V” when entering a ship name in EMu.

The identifier assigned by the organization that operates a vessel to a research cruise, that is, a continuous, port-to-port voyage conducted to make observations or collect specimens. The terms “cruise” and “leg” are interchangeable for the purposes of this field.
Usage
Omit if no appropriate data is available
Format
Typically, the identifier is either a number or an alphanumeric code. Cruise number formats vary widely between or even within organizations, with different abbreviations, delimiters, or zero-padding conventions being used in different documents. There are no hard rules for formatting a cruise number, but a good practice is to search for a vessel name to see how cruise numbers for that vessel have been recorded previously.
Cruise numbers should include the leg if known, and legs should not be recorded elsewhere (for example, in notes). Many organizations already incorporate the leg into their cruise identifiers, but if not, it is acceptable to append the leg to the cruise number. For example, leg 2 of cruise ABCD can be entered as “ABCD-2”.

Date |
The start and end dates for an expedition or cruise
Usage
Omit if no appropriate data is available
Format
EMu depicts dates using the following formats:
Year, month, and day: 1 Jan 1970
Year and month: Jan 1970
Year: 1970
It accepts a variety of formats in addition to the display formats above, including but not limited to: * January 1, 1970 * Jan 1, 1970 * 1970-01-01 * 1970-01 * 0101970
Use the most specific date format possible.
If only a single date is available, include that date in both the start and completion date fields. For example, if a cruise took place in Jan 1970 but the exact start and end dates are not known, enter “Jan 1970” in both fields. If a cruise took place in 1970 and the exact dates are not known, enter “1970” in both fields.

Collection Method |
The device used to collect a specimen
Usage
Required for marine specimens and terrestrial drill cores. Omit otherwise. Specimens collected during routine field work do not need to indicate a collection method.
Format
The format of this field is under review. Historically, we have only captured three collection methods: core (sometimes given as drill core), dredge, and submersible. NOAA’s IMLGS includes a more detailed vocabulary that may be worth a look.

Core
Dredge
Submersible (HOV)
Submersible (ROV)
