These seismic data were collected to infer the paleodepositional environment of Pulley Ridge through seismic facies analysis. Without actual rock cores, remote sensing is the next best tool. It was uncertain if Pulley Ridge represented a drowned reef or paleoshoreline. Through seismic imaging, it was determined from the high-amplitude, level-bedded nature of material in the sub-surface that Pulley Ridge represents several stages of barrier-island development. For more information on the seismic surveys see http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2001-010-FA These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.本数据集采集的地震数据旨在通过地震相分析（seismic facies analysis）推断普利岭（Pulley Ridge）的古沉积环境。在缺乏实际岩心的情况下，遥感（remote sensing）为次优替代探测手段。此前学界对普利岭（Pulley Ridge）究竟属于淹没礁（drowned reef）还是古岸线（paleoshoreline）尚无定论。通过地震成像（seismic imaging）对地下介质的高振幅、水平层状特征开展分析后，最终确定普利岭（Pulley Ridge）经历了多期障壁岛（barrier-island）的发育演化过程。 如需了解本次地震勘探的详细信息，请访问：http://woodshole.er.usgs.gov/operations/ia/public_ds_info.php?fa=2001-010-FA 该数据集还可通过GeoMapApp（http://www.geomapapp.org/）与Virtual Ocean（http://www.virtualocean.org/）两款地球科学勘探与可视化应用程序获取。
