The conference details are already up on their website as is the call for papers (deadline is July 1, 2009). Their CFP also mentions a new journal:
The Maritime Conference Program Committee invites individual paper proposals and full panels (three proposals and a chair) on any aspect of the individual's or civilization's relationship with the sea through literature, history, or culture. Papers or panels may address such areas as literary writers and the sea from any period in American or global history; exploration; whaling; merchant or naval history; personal narratives of life at sea; survival literature; war at sea; the visual artist and the sea; poetry and the sea; or any other subject addressing our engagement with the sea through the humanities.
Selected conference papers will be published in the premier issue of the Academy's new annual peer-reviewed journal, The Nautilus: A Maritime Journal of Literature, History, and Culture, forthcoming in 2010.
I look forward to seeing the journal!
