Abstract:
During spring (3 April – 15 May 2019) the Northeast Fisheries Science Center (NEFSC) conducted aerial abundance surveys targeting marine mammals and sea turtles. The southwestern extent was New Jersey and the northeastern extent was off of Halifax, Nova Scotia, Canada on the Scotia Shelf. The surveys covered waters from the coastline to about the 2000-m depth contour. Track lines were flown 183 m (600 ft) above the water surface, at about 200 kph (110 knots). The two-independent team methodology was used to collect data. Approximately 10,392 km of on-effort track lines were surveyed, where 89% of this effort was in Beaufort 3 and below.

摘要：2019年春季（4月3日至5月15日），美国国家海洋和大气管理局东北渔业科学中心（NOAA Northeast Fisheries Science Center, NEFSC）开展了针对海洋哺乳动物与海龟的航空丰度调查。本次调查的西南端点为美国新泽西州，东北端点则位于加拿大新斯科舍省哈利法克斯外海的新斯科舍陆架海域。调查覆盖了从海岸线至约2000米等深线的海域。勘测航线以距水面183米（600英尺）的高度飞行，航速约200公里/小时（110节）。本次调查采用双独立团队方法开展数据采集工作。累计完成有效作业航线勘测里程约10392公里，其中89%的作业时段海况处于蒲福风级3级及以下。
