Between November 1989 and March 2013, 1033 Antarctic fur seals Arctocephalus gazella were observed entangled in marine debris at Bird Island, South Georgia. The majority of entanglements involved plastic packaging bands (43%), synthetic line (25%) or fishing net (17%). Juvenile male seals were the most commonly entangled (44%). A piecewise regression analysis showed that a single breakpoint at 1994 gave the best description of inter-annual variability in the data, with higher levels of entanglements prior to 1994 (mean=110±28) followed by persistent lower levels (mean=28±4). Records of entanglements from other sites monitored in the Scotia Sea are also presented. Legislation imposed by the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) has, to a certain extent, been effective, but persistent low levels of seal entanglements are still a cause for concern at South Georgia.
1989 年 11 月至 2013 年 3 月期间，在南乔治亚的伯德岛观察到 1033 只南极软毛海豹（Arctocephalus gazella）被海洋废弃物缠住。大多数纠缠涉及塑料包装带（43%）、合成线（25%）或渔网（17%）。幼年雄性海豹最常被缠住（44%）。分段回归分析表明，1994 年的单一断点可以最好地描述数据的年度间变化，1994 年之前的纠缠水平更高（平均值=110±28），随后是持续较低的水平（平均值=28±4）。还介绍了斯科舍海其他监测点的纠缠记录。南极海洋生物资源保护委员会（CCAMLR）实施的立法在一定程度上是有效的，但南乔治亚海豹持续低水平的纠缠仍然令人担忧。
