I deleted the menus below the banner for Ocean Heat Content and for the Sea Surface Temperature Updates. I wasn’t maintaining them.
I have, however, added a widget for post categories to the right-hand sidebar. Ocean Heat Content and SST Updates are included. I’ve been working my way back through the posts to categorize them. I’ve gone back as far as February 2010 as of today and I’ll try to finish those changes in the next couple of weeks.
