You're probably looking for the map with the tide and current prediction stations on it.
It's been moved here: Tide and Current Map
Sorry about that. I personally hate it when web site admins randomly move links around. However, in order to do some maintenance (including bringing online a much-more capable server, adding more pages with additional information and additional ways of displaying tide and current information, and switching to a much larger database using XTide data as well as/instead of NOAA data), I've found it useful to make this change. I'm pretty sure I won't be changing the link paths again any time soon, so go ahead and bookmark the new link. Trust me.
You can see other choices for getting prediction information here:
You might want to check back to this welcome page every now and then, though. The new content will appear as links in this page.
Some things I hope to implement in the near future:
1. Online and offline support for mobile devices such as the iPhone/iPod (via HTML5)
2. The ability to create and download lists of dates, or possibly calendar documents, matching a particular general condition (like all weekend dates with mid-morning ebb currents in Hammersley Inlet, for example).
3. Some general content, maybe even a lesson plan, on trip planning using tides and current predictions.
4. A way to 'crowdsource' content for this site.
