Grand Manan Basin - Deep Water Sediment Community (OBIS Canada)

This study investigates the faunal biodiversity of the deep water sediments of Grand Manan Basin in the Bay Fundy on the East Coast of North America. Specimens were collected using a 0.1m2 grab, and identified and enumerated at the Atlantic Reference Centre. The sediment types at the research sites were found to be complex containing cobbles, pebbles, sand and clay. The specimens retrieved from these samples showed a great degree of biodiversity, and include species not previously reported in this region.

本研究针对北美东海岸芬迪湾（Bay Fundy）内格兰德曼安盆地（Grand Manan Basin）的深水沉积物动物群生物多样性展开调查。研究采用0.1平方米抓斗采泥器（0.1m2 grab）采集沉积物样本，并于大西洋参考中心（Atlantic Reference Centre）完成标本的鉴定与计数工作。经检测，本次研究点位的沉积物类型复杂多样，涵盖巨砾、砾石、砂与黏土。从上述样本中获取的标本展现出极高的生物多样性，其中包含该区域此前未曾记录的物种。
