F. Smith. Version 1 was officially introduced to Lamont scientists in July 1988. <A NAME="tex2html29" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> 1 migrated by word of mouth (and tape) to other institutions in the United States, UK, Japan, and France and attracted a small following. Paul took a Post-doctoral position at SOEST in December 1989 and continued the <A NAME="tex2html30" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> development. Version 2.0 was released with an article in EOS, October 1991, and quickly spread worldwide. We obtained NSF-funding for <A NAME="tex2html31" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> version 3.0 in 1993 which was released with another article in EOS on August 15, 1995. Significantly improved versions (3.1-3.3, 3.3.1-6), 3.4, 3.4.1-5, and 4.0-4.5.1 were released between November 1998 and September 2009, culminating in the Jan 2010 introduction of 4.5.2. <A NAME="tex2html32" HREF="http://gmt.soest.hawaii.edu"><B>GMT</B></A> now is used by <IMG WIDTH="16" HEIGHT="15" ALIGN="BOTTOM" BORDER="0" SRC="img4.png" ALT="$\sim$">15,000 users worldwide in a broad range of disciplines. <P> <HR> <!--Navigation Panel--> <A NAME="tex2html417" HREF="node5.html"> <IMG WIDTH="37" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="next" SRC="next.png"></A> <A NAME="tex2html411" HREF="node3.html"> <IMG WIDTH="26" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="up" SRC="up.png"></A> <A NAME="tex2html405" HREF="node3.html"> <IMG WIDTH="63" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="previous" SRC="prev.png"></A> <A NAME="tex2html413" HREF="node1.html"> <IMG WIDTH="65" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="contents" SRC="contents.png"></A> <A NAME="tex2html415" HREF="node63.html"> <IMG WIDTH="43" HEIGHT="24" ALIGN="BOTTOM" BORDER="0" ALT="index" SRC="index.png"></A> <BR> <B> Next:</B> <A NAME="tex2html418" HREF="node5.html">Philosophy</A> <B> Up:</B> <A NAME="tex2html412" HREF="node3.html">GMT overview: History, philosophy,</A> <B> Previous:</B> <A NAME="tex2html406" HREF="node3.html">GMT overview: History, philosophy,</A> <B> <A NAME="tex2html414" HREF="node1.html">Contents</A></B> <B> <A NAME="tex2html416" HREF="node63.html">Index</A></B> <!--End of Navigation Panel--> <ADDRESS> Paul Wessel 2010-01-14 </ADDRESS> </BODY> </HTML>
