They are also primarily found in the lower portion of the Bay of Fundy, with some individuals observed in the upper Bay (Figure 11-5; NOAA 2012). The minimum population estimate for the Gulf of Maine and Bay of Fundy was 823 individuals in 2008 (NOAA 2012). Minke whales found in the Bay of Fundy are considered to be part of the Canadian East Coast stock with an estimated abundance of 20,741 individuals in 2007 (NOAA 2013a). They are typically observed in the Bay from July to September, with some individuals remaining year round (Lien 2001). They are usually concentrated in the lower Bay (Ingram et al. 2007), with some observations occurring in the upper Bay (Figure 11-6). Atlantic white-sided dolphin and harbour porpoise, both toothed whales, are found-year round in the Bay of Fundy. Harbour porpoise has a wider distribution within the Bay of Fundy than Atlantic white-sided dolphin, although both species have concentrations in the lower part of the Bay (Figure 11-7 and Figure 11-8). The Gulf of Maine/Bay of Fundy harbour porpoise stock was estimated to have 79,883 individuals in 2011 (NOAA 2013b). The highest densities of harbour porpoises are observed during the summer (July and August) when feeding (Trippel et al. 1999), while densities decrease during the winter as many individuals migrate south to the eastern coast of the US (NOAA 2013b). Individuals have been observed in the upper Bay of Fundy and along the south and west shores of Nova Scotia, but numbers are much higher in the lower Bay of Fundy (COSEWIC 2006; Palka 2000). Atlantic white-sided dolphin densities in the Gulf of Maine and Bay of Fundy are higher in the summer and lower in the winter when the species move south down the northeastern seaboard of the United States (Northridge et al. 1997). They have been sighted throughout the Bay of Fundy, although concentrated in the lower half of the Bay and have an abundance estimate of 48,819 individuals in 2011 (NOAA 2013c). Harbour seals are the only pinniped species commonly found within the RAA, with highest abundances in the summer, but are present year-round (Jacobs and Terhune 2000; Rosenfeld et al. 1988; NOAA 2014). They are found throughout the Bay of Fundy, including near industrialized sites, with the highest abundance in the lower Bay of Fundy and moderate abundance in the upper Bay (Stobo and Fowler 1994). The best Canadian estimate of abundance is approximately 10,000 animals, based on summing other population estimates (COSEWIC 2007a). Marine mammal species, including SARA-listed species that are most likely to occur in the RAA are listed in Table 11-2. Energy East Pipeline Ltd.
