            <gco:CharacterString>Advanced Very High Resolution Radiometer

A meteorological satellite [instrument] with two bands that is used for large area Earth observation at 1 km spatial resolution. Source: Glossary of GIS and Remote Sensing Terms, University of Vermont. (http://fwie.fw.vt.edu/tws-gis/glossary.htm; last accessed on 09/22/2004).

Specifically, this instrument type is to be used to represent AVHRR/1: "There are two series of AVHRR instruments. Built by ITT Aerospace/Optical Division in the mid 1970s, the AVHRR/1 is a four-channel, filter-wheel spectrometer/radiometer (Appendix) while the AVHRR/2, built in the early 1980s, is identical except for the addition of Channel 5."

            <gco:CharacterString>Updated information from ICES for the vessel CHARLES DARWIN from UNITED KINGDOM

Code : 74AB
Name : CHARLES DARWIN
Flag : UNITED KINGDOM - GB (ISO Country Code)
Call Sign : GDLS
Title : RRS
Platform Class : Research vessel
IMO : 8207941
Commissioned Date : 1985-02-13
Decommissioned Date : 2006-06-30
Current Length : 69.4
Built : 1984
Notes : NERC deep-sea research vessel until sold in July 2006 and renamed Ocean Researcher.

Same Vessels Info
74OA - OCEAN RESEARCHER

General Comments:
Wikipedia claims a build date of 1985, which is incorrect. I saw her in Falmouth fully fitted out and undergoing acceptance trials in September 1984. 1985-02-13 is date of first cruise.

In Jan. 2007, the name associated with the code 74AB was changed to OCEAN RESEARCHER. In Feb. 2007 an additional code was created for the OCEAN RESEARCHER. In 2009, the platform group agreed attribute change and code creation procedures. The name for 74AB was changed back to CHARLES DARWIN.</gco:CharacterString>
