Many thousands of kilometers of high resolution seismic data and hundreds of sediment cores were collected using our research vessel R/V Lone Star during the past ten years. We completed data collection on the continental shelf and sold the Lone Star in 2000. We have purchased a new vessel, the R/V Trinity. The Trinity allows us to work in much shallower water and to take longer cores.
