This web site makes extensive use of CSS for styling
AND to display mouse-over 'pop ups' of images.
If you can read this message, it is probable that the header image is not displaying because your browser does not properly
support CSS or you have disabled this yourself.
Although the content looks better with with CSS 'turned on', this site is perfectly readable either way.
I have a long-held interest in Antarctica - its history and wildlife - and I have a fascination with icebergs. I just had to get this one out of my system!.
