摘要： Seagrass meadows (Zostera marina) are important coastal ecosystems with high levels of productivity and biodiversity. They often have high biomass turnover and are susceptible to dislodgment, leading to export of biomass from seagrass beds. In September 2016, two cruises covering a total area of 52 km x 15 km (38 degrees 57'1.14 ''-39 degrees 0'41.28 '' N, 118 degrees 45'23.22 ''-118 degrees 47'6.96 '' E) found floating Z. marina aggregations along 13 km of the transect in the northernmost area of Bohai Bay, in the Bohai Sea, China. This floating seagrass was 6.3-13.4 km northeast (offshore) of the Caofeidian seagrass bed, which is a large (10 km(2)) seagrass bed discovered in 2015 in the Bohai Sea, China. The modal length of floating intact shoots (from meristem to longest leaf tip) matched samples from the Caofeidian seagrass bed. The dominant individuals lengths were 40-50 cm, with less than 5% of the total number of individuals found in larger size categories (80-90 and 90-100 cm). We concluded that they originated from the nearby Caofeidian seagrass meadows.
