Thanks Brian, I'll pass that mis-link along. Canie, yes to all. It is a very deep bathymetric basin: 3 basins each with water deeper than 1200 m, and the young sedimentary basins plus the water are as much as about 6 km, as shown by the deep crustal seismic from the French (the upper part of one of these French profiles is shown under "approach": Seismarmara leg 2; this profile images far deeper than does our data, but as shown the esolution is not as good.

These basins are indeed somewhat similar to LA basin, but maybe a bit more to some of the offshore basins. The difference is that most of the basins in southern California, including LA basin, have there modern form mainly from thrusting causing uplift around them, with the sediment and tectonic loads enhancing subsidence of the basins. The Marmara basins are mainly formed by an extensional component across segments of the North Anatolian fault, so maybe a little like northern Salton Trough.

There are, however, thrust folds that form ridges in Marmara Sea. These are poorly understood, even by us, and have been publiched over and over as horsts (extensional structures), which is wrong. I wrote a letter to GSA Today (Sorlien and Seeber, 2000) to say that the published Aksu et al model for this did not make sense.

I spent part of this past week trying to do advanced processing to remove the water layer reverberation ("multiples"), on a profile that crosses the Marmara Sea southern basins and shelf, including deltas, and this was not sucessful. I am now trying to do the same for a seismic reflection profile that is part of our site survey for IODP in Santa Barbara Basin (Nicholson, Sorlien, Kennett, Behl, Marshall, others).
