远洋船舶携带的海水作为压舱物，在港口被吸收，并在随后的停靠港被释放。从日本压载水释放在俄勒冈州的浮游生物样本包含367个分类群。在压载水中发现了大多数在其生命周期中处于水生阶段的类群，所有主要的海洋生境和营养类群也是如此。整个沿海浮游生物群落跨越海洋屏障迁移到相似的生境，使海湾、河口和内陆沃茨成为世界上最受威胁的生态系统。这些样本中存在分类困难或不显眼的类群表明压载水入侵已经普遍存在。
Ocean-going ships carry, as ballast, seawater that is taken on in port and released at subsequent ports of call. Plankton samples from Japanese ballast water released in Oregon contained 367 taxa. Most taxa with a planktonic phase in their life cycle were found in ballast water, as were all major marine habitat and trophic groups. Transport of entire coastal planktonic assemblages across oceanic barriers to similar habitats renders bays, estuaries, and inland waters among the most threatened ecosystems in the world. Presence of taxonomically difficult or inconspicuous taxa in these samples suggests that ballast water invasions are already pervasive.
