英国诺森伯兰郡近海沃茨水域是海洋哺乳动物和海鸟等海洋巨型动物的重要栖息地。该地区还拥有广泛的人类活动，包括航运，海洋可再生能源开发，渔业和旅游业。同时，缺乏关于齿鲸发生的基线数据，无法评估人为干扰的潜在影响。最近在该地区看到普通海豚（Tursiops truncatus）的数量增加，为保护管理人员和政策制定者提供了新的数据。为了提供这一信息，声学数据收集使用宽带被动声记录仪在三个站点（Druridge湾，滨海纽宝因，和圣玛丽的岛）关闭诺森伯兰郡海岸和分析，以确定物种特定的点击列车常见的海豚，白喙海豚（Laguhynchus albirostris）和港口鼠海豚（Phocoena phocoena）。检测数据建模为每个物种的检测阳性小时（DPH）使用广义加性模型与广义估计方程（GAM-GEE），以调查环境协变量的影响，包括一年中的一天，昼夜相位，月相，盐度，年，月和海面温度，以及它们与位置的相互作用。在研究期间共记录了20，845小时，分别为白海豚、白嘴海豚和鼠海豚确定了1660、71和1111只DPH。海豚的最终模型保留了所有的协变量，除了潮汐指数和模型选择后的位置和一年中的一天之间的相互作用，最终模型中的所有协变量都是显着的。最终的模型保留的月份，年份，位置，昼夜指数，温度，月球指数和位置和昼夜指数之间的相互作用和所有的协变量，除了月球指数显着的白嘴海豚。海豚的最终模型保留了所有的协变量和位置和昼夜相位，一年中的日子，月球指数和盐度之间的相互作用，但是，盐度和位置和月球指数之间的相互作用并不显着。宽吻海豚点击检测在该地区全年，但有两个高峰期发生在5月和9月下旬;白喙海豚点击检测主要是在7月和8月;和海豚点击是目前全年，但更大的概率检测在Druridge湾网站，那里有高峰在冬季和9月。这项研究的结果提供了重要的信息，保护和管理行动，可能需要减少英国沃茨的齿鲸类的人为压力。
Nearshore coastal waters off Northumberland, UK, are important habitats for marine megafauna including marine mammals and seabirds. The area also features extensive anthropogenic activities including shipping, marine renewables development, fisheries, and tourism. Meanwhile there is lack of baseline data on odontocete occurrence to allow assessment of the potential impact from human disturbance. A recent increase in the number of sightings of common bottlenose dolphins (Tursiops truncatus) in the area has provided impetus for new data to inform conservation managers and policy makers. To provide this information, acoustic data were collected using broadband passive acoustic recorders at three sites (Druridge Bay, Newbiggin-by-the-Sea, and St Mary's Island) off the Northumberland coast and analyzed to identify species-specific click trains of common bottlenose dolphin, white-beaked dolphin (Lagenorhynchus albirostris) and harbor porpoise (Phocoena phocoena). Detection data were modelled for each species as detection-positive hours (DPH) using Generalized Additive Models with Generalized Estimating Equations (GAM-GEE) to investigate the effects of environmental covariates, including day of year, diel phase, lunar phase, salinity, year, month and sea surface temperature, and their interaction with location. A total of 20,845 h were recorded during the study resulting in a total of 1660, 71, and 1111 DPH identified for bottlenose dolphin, white-beaked dolphin and porpoise, respectively. The final model for bottlenose dolphins retained all covariates except tidal index and an interaction between location and day of year after model selection and all covariates in the final model were significant. The final model for white-beaked dolphin retained month, year, location, diel index, temperature, lunar index and interactions between location and diel index and all covariates except lunar index were significant. The final model for porpoise retained all covariates and interactions between location and diel phase, day of year, lunar index, and salinity, however, salinity and the interaction between location and lunar index were not significant. Bottlenose dolphin clicks were detected in the area year-round but with two peak periods in occurrence coinciding with May and late September; white-beaked dolphin clicks were detected predominantly in July and August; and porpoise clicks were present year-round but with much greater probability of detection at the Druridge Bay site, where there were peaks in winter and in September. The results of this study provide important information for conservation and management actions that may be needed to reduce anthropogenic pressures on odontocetes in UK waters.
