Subject: Completion of Geophysical Work under Notice No. N03-01

Dear Ron:

In accordance with 30 CFR 251.4 (b) (2), this letter is to inform you that USGS has completed the geophysical research cruise that is assigned Notice Number N03-01.

The cruise took place on 1-14 May in the north central Gulf of Mexico aboard R/V Gyre, operated by Texas A&M. We collected more than 1000 km of high-resolution multichannel seismic reflection data in the vicinity of lease blocks Keathley Canyon 195 and Atwater Valley 14. We also collected profiles that connected these new data sets to the two multichannel data sets that USGS collected in 1998 and 1999. A cruise report summarizing the data and results is being sent to Mike Smith at MMS under separate cover.

Please call me if you have questions or need additional information about this cruise.

                                                              Sincerely yours,



                                                              Deborah R. Hutchinson
