After a bit of a sabbatical, the Eastern Korinthia Archaeological Survey (EKAS) has returned to the web (albeit only in beta... for now).
Survey projects on the web are tricky things.
Nemea Valley Archaeological Project
Pylos Regional Archaeological Project
Sydney Cyprus Survey Project
Troodos Archaeological and Environmental Survey Project
Rough Cilicia Archaeological Survey Project
Kythera Island Project
Pyla-Koutsopetria Archaeological Project
Australia Paliochora Kythera Archaeological Survey
Saronic Harbors Exploration Project
Sikyon Survey Project
The Shala Valley Project
As these links suggest, survey project websites are a mixed bag. (In fact I could not find any presence on the web for some projects like the Nikopolis Survey and the massive, long running, and complex Argolid Exploration Project (aka Southern Argolid Survey)). It seems to me that since many survey projects tend to be less stable institutional entities with life spans between a few years and a decade and make little investment in semipermanent, physical infrastructure (e.g. dig houses, site guards, fences, et c.), this often translates to instability on the web. Big digs, in contrast, with their well-developed infrastructures, long term (and sometimes permanent) staff, and persistent financial commitments from home institutions seem to have better chances for producing a stable presence on the Internet. The preceding links to survey projects show how most (but not all!) have broken links, pictures that fail to appear, or offer little more than static data (nice photos, some maps... in fact, much of this doesn't count as data at all; of course, some surveys, like the the Sydney Cyprus Survey Project, have archived their data officially in places like the Arts and Humanities Data Service ).
None of these observations are profound, and this is not to suggest that EKAS is better. In fact, EKAS totally vanished from the web for a time (and because it's previous home http://web.stcloudstate.edu/eleftheria/ blocked robots like the Internet Archive the site is gone from public view in a profound way! One cannot even "excavate" an early version of the site).
This is all to say that EKAS has reemerged, and the only reason that it has come back is because for David Pettegrew's class in Classical Archaeology. So, enjoy it while you can!
