Effects of the Exxon Valdez oil spill on the abundance and distribution of humpback whales (Megaptera novaeangliae) in Prince William Sound by Marilyn E Dahlheim( Book )

"Photo-identification studies of Prince William Sound humpback whales were conducted from May to September in 1989 and 1990 to assess the impact of the spill on humpback whale life history and ecology. In 1989, concurrent studies were conducted in Southeast Alaska on humpback whales to determine if whales avoided contaminated waters of PrInce William Sound and moved to other northern feeding areas. In 1989, photographic analysis of Prince William humpbacks resulted in the identification of 59 whales. In 1990, 66 whales were documented. More whales were seen in these two seasons than any year previous to the spill. The increase in whale sightings may have been due to the increase in effort during the 1989 and 1990. Because of the difference in survey effort before and after the spill, it is impossible to determine if in the number of humpback whales using the Sound. Distribution varied among years and may be related to prey distribution. Only one Prince William Sound humpback whale was documented to move from Prince William Sound to southeastern Alaska during the 1989 season. Calving rates during 1989 and 1990 were not significantly different than in previous years. No reports of dead stranded humpback whales occurred during the study period. No observations were made of humpback whales swimming through oil"--Abstract

Assessment of injuries and recovery monitoring of Prince William Sound killer whales using photo-identification techniques by Marilyn Elayne Dahlheim( Book )

2 editions published in 1994 in English and held by 11 WorldCat member libraries worldwide

"Photo-identification studies of individual killer whales inhabiting Prince William Sound were collected from 1989-91 and from July to September 1993 to determine the impact of the spill on whale abundance and distribution (1989-1991) and monitor recovery (1993). Concurrent photo-identification studies were also conducted in Southeast Alaska to determine if PWS killer whales were displaced to other areas between 1989 and 1991. Despite increased effort, the number of encounters with PWS killer whales appears to be decreasing. Analysis of photographic data revealed 14 animals missing from AB pod over the three-year period. Mortality rates for AB pod ranged from 3.1% in 1988 to 19.4% in 1989, 20.7% in 1990, and 4.3% in 1991. Zero mortality occurred in 1992 and 1993. Mortality rates on the order of 20% are unprecedented for North Pacific killer whales. No new calves were born into AB pod in 1989 or 1990. There was one calf born in 1991, two born in 1992, and one born in 1993. AB pod size in 1988 was 36; in late 1993 the pod had 26 members. The cause(s) of the disappearance of 14 killer whales from AB pod is unknown. We assume, that the whales are dead from natural causes, a result of interactions with fisheries, from the spill, or a combination of these causes"--Abstract

Southern Resident Killer Whale Workshop : National Marine Mammal Laboratory, Seattle, WA, 1-2 April 2000 by Southern Resident Killer Whale Workshop( Book )

1 edition published in 2000 in English and held by 7 WorldCat member libraries worldwide

"Since 1974, a census of the southern resident community of killer whales (J, K, and L pods) of Puget Sound has been taken annually using photo-identification methodology. Based on this research, the southern resident killer whale population was shown to grow to nearly 100 individuals by the mid-1990s. However, during the last few years (1995-99), a decline in population level has been observed. In May 1995, the population count was 98 individuals. By October 1999 this number had dropped to 83 whales, a decline of more than 15%. Possible factors influencing the southern resident community of killer whales included high levels of contaminants, availability of prey resources, and increased whale watching activities in the San Juan islands. Killer whale researchers believed a workshop was warranted to review the status of southern resident killer whales. On 1 and 2 April 2000, a killer whale workshop was held at the National Marine Mammal Laboratory on 1 and 2 April 2000, a killer whale workshop was held at the National Marine Mammal Laboratory in Seattle, Washington. Sponsors of the workshop included the Alaska Fisheries Science Center (National Marine Mammal Laboratory), Center for Whale Research, Six Flags Marine World Vallejo, and The Whale Museum. Contributions were made by the Department of Fisheries and Oceans (DFO Canada) and the American Cetacean Society. The purpose of the workshop was to review the current status of southern resident killer whales and help the research community coordinate future research. The workshop focused on four areas of research to include: 1) Population Dynamics of Eastern North Pacific Killer Whales, 2) Stock structure of Eastern North Pacific Killer Whales, 3) Possible Factors Influencing Killer Whale Populations, and 4) Cross-Border Stranding Protocol/Emergency Responses. In addition to several oral presentations covering these topics, background documents were also submitted"--Preface

"On 30 April 1994, Public Law 103-238 was enacted allowing significant changes to provisions within the Marine Mammal Protection Act (MMPA). Interactions between marine mammals and commercial fisheries are addressed under three new sections. This new regime replaced the interim exemption that has regulated fisheriesrelated incidental takes since 1988. Section 117, Stock Assessments, required the establishment of three regional scientific review groups to advise and report on the status of marine mammal stocks within Alaska waters, along the Pacific Coast (including Hawaii), and the Atlantic Coast (including the Gulf of Mexico). This report provides information on the marine mammal stocks of Alaska under the jurisdiction of the National Marine Fisheries Service"--Preface.

"On 30 April 1994, Public Law 103-238 was enacted allowing significant changes to provisions within the Marine Mammal Protection Act (MMPA). Interactions between marine mammals and commercial fisheries are addressed under three new sections. This new regime replaced the interim exemption that has regulated fisheriesrelated incidental takes since 1988. Section 117, Stock Assessments, required the establishment of three regional scientific review groups to advise and report on the status of marine mammal stocks within Alaska waters, along the Pacific Coast (including Hawaii), and the Atlantic Coast (including the Gulf of Mexico). This report provides information on the marine mammal stocks of Alaska under the jurisdiction of the National Marine Fisheries Service. Each stock assessment includes, when available, a description of the stock’s geographic range; a minimum population estimate; current population trends; current and maximum net productivity rates; optimum sustainable population levels and allowable removal levels; estimates of annual human-caused mortality and serious injury through interactions with commercial, recreational, and subsistence fisheries, takes by subsistence hunters, and other human-caused events (e.g., entanglement in marine debris, ship strikes); and habitat concerns. The commercial fishery interaction data will be used to evaluate the progress of each fishery towards achieving the MMPA’s goal of zero fishery-related mortality and serious injury of marine mammals. The Stock Assessment Reports should be considered working documents, as they are updated as new information becomes available. The Alaska Stock Assessment Reports were originally developed in 1995 (Small and DeMaster 1995). Revisions have been published for the following years: 1996 (Hill et al. 1997), 1998 (Hill and DeMaster 1998), 1999 (Hill and DeMaster 1999), 2000 (Ferrero et al. 2000), 2001 (Angliss et al. 2001), 2002 (Angliss and Lodge 2002), 2003 (Angliss and Lodge 2004), 2005 (Angliss and Outlaw 2005), 2006 (Angliss and Outlaw 2007), 2007 (Angliss and Outlaw 2008), 2008 (Angliss and Allen 2009), 2009 (Allen and Angliss 2010), 2010 (Allen and Angliss 2011), 2011 (Allen and Angliss 2012), 2012 (Allen and Angliss 2013), 2013 (Allen and Angliss 2014), 2014 (Allen and Angliss 2015), and 2015 (Muto et al. 2016). Each Stock Assessment Report is designed to stand alone and is updated as new information becomes available. The MMPA requires Stock Assessment Reports to be reviewed annually for stocks designated as strategic, annually for stocks where there is significant new information available, and at least once every 3 years for all other stocks. New information for all strategic stocks (Western U.S. Steller sea lions, northern fur seals, Cook Inlet beluga whales, AT1 Transient killer whales, harbor porpoise, sperm whales, humpback whales, fin whales, North Pacific right whales, and bowhead whales) was reviewed in 2015-2016. This review, and a review of other stocks, led to the revision of the following stock assessments for the 2016 document: Western U.S. and Eastern U.S. stocks of Steller sea lions; northern fur seals; bearded seals; ringed seals; Cook Inlet beluga whales; narwhals; Eastern North Pacific (ENP) Alaska Resident, ENP Gulf of Alaska, Aleutian Islands, and Bering Sea Transient, and AT1 Transient stocks of killer whales; Southeast Alaska, Gulf of Alaska, and Bering Sea stocks of harbor porpoise; sperm whales; Western North Pacific and Central North Pacific stocks of humpback whales; fin whales; North Pacific right whales, and bowhead whales. The Stock Assessment Reports for all stocks, however, are included in this document to provide a complete reference. Those sections of each Stock Assessment Report containing significant changes are listed in Appendix 1. The authors solicit any new information or comments which would improve future Stock Assessment Reports. The U.S. Fish and Wildlife Service (USFWS) has management authority for polar bears, sea otters, and walruses. Copies of the stock assessments for these species are included in Appendix 8 of this NMFS Stock Assessment Report for your convenience. Ideas and comments from the Alaska Scientific Review Group (SRG) have significantly improved this document from its draft form. The authors wish to express their gratitude for the thorough reviews and helpful guidance provided by the Alaska Scientific Review Group members: Karl Haflinger, Lloyd Lowry (Chair from 2012 to 2016), Beth Mathews, Craig Matkin, Mike Miller, Grey Pendleton, Robert Small, Kate Stafford, Robert Suydam, David Tallmon, and Kate Wynne. We would also like to acknowledge the contributions from the NMFS Alaska Region and the Communications Program of the Alaska Fisheries Science Center. The information contained within the individual Stock Assessment Reports stems from a variety of sources. Where feasible, we have attempted to utilize only published material. When citing information contained in this document, authors are reminded to cite the original publications, when possible"--Preface.
