Densities of fishes, invertebrates and plants at rocky intertidal and shallow subtidal sites were censused 1-2 days prior to the Jessica oil spill and compared with information obtained for the same sites one month after the spill, both for sites impacted by oil and unaffected reference sites. While the availability of pre-spill data made this analysis one of the most powerful to date for testing impacts of oil on shoreline environments, no clear changes attributable to oiling could be identified. Discharged oil appeared to cause very little impact in the intertidal and shallow subtidal zones, with such impacts lying within the range of natural spatial and temporal variation at sites investigated. Factors considered to minimize impact in Galápagos included paucity of fully sheltered shores in spill path, moderate wave action, warm temperature, high levels of sunlight, and mixing of bunker oil with diesel.
在杰西卡号石油泄漏事件发生前1至2天，对岩石潮间带和浅潮下带的鱼类、无脊椎动物和植物密度进行了普查，并与泄漏事件发生一个月后在同一地点获得的信息进行了比较，这些地点既有受石油影响的，也有未受影响的参考地点。虽然溢油前的数据可用性使这项分析成为迄今为止测试石油对海岸线环境影响最有力的分析之一，但无法确定任何可归因于油污的明显变化。排放的石油似乎对潮间带和浅潮下带造成的影响很小，这种影响处于所调查地点自然空间和时间变化的范围内。在加拉帕戈斯群岛，被认为可将影响降至最低的因素包括溢油路径中完全遮蔽的海岸较少、适度的海浪作用、温暖的温度、充足的阳光以及燃料油与柴油的混合。
