 | In this one-year limited-scope study, the objectives were to test our ability to make key measures needed to study the role of nutritive body condition in the behavior and reproduction in the Northern bottlenose whale (Hyperoodon ampullatus) and the humpback whale (Megaptera novaeangliae). Our approach was to collect animal-attached tag data, photographs, and tissue samples during three research trials in Canada and Norway and from opportunistic sources. Every one of ... |

|
| The goal of this project is to improve our ability to predict the behavioral response of beaked whales to mid-frequency active (MFA) sonar, by making better use of data already collected, or being collected as part of other projects. We aim to construct and fit mathematical models of the diving behavior of beaked whales, and their response to MFA sonar. These models will be parameterized by fitting them simultaneously to ... |

|
| This is the report of the second behavioral response study to be carried out on beaked whales and pilot whales in which these animals, and other species, were exposed to carefully measured doses of underwater sound while their responses were being measured. The study is seen as a step in a series of similar experiments that are designed to safely identify the behavioral mechanisms that may be involved in the ... |

|
| Data on the responsiveness of free-ranging cetaceans to mid-frequency sonar signals are lacking, with only a few species having been studied in relation to a few types of sonar signals, mostly SURTASS-LFA (Nowacek et al., 2007). This specific project was initially motivated by observations of possible killer whale (Orcinus orca) reactions to sonars, in the Vestfjord basin of Norway and the USS Shoup incident in Haro Strait in Washington State. ... |

| Could Beaked Whales get the Bends? Effect of Diving Behaviour and Physiology on Modelled Gas Exchange for Three Species: Ziphius Cavirostris, Mesoplodon Densirostris and Hyperoodon Ampullatus |

|
| A mathematical model, based on current knowledge of gas exchange and physiology of marine mammals, was used to predict blood and tissue tension N2 (PN2) using field data from three beaked whale species: northern bottlenose whales, Cuvier's beaked whales, and Blainville's beaked whales. The objective was to determine if physiology (body mass, diving lung volume, dive response) or dive behaviour (dive depth and duration, changes in ascent rate, diel behaviour) ... |

|
| Obtaining reliable estimates of the density and distribution of cetacean species is an essential component of a risk mitigation strategy, as well as having other conservation and management uses. The overall goal of this research program was to develop statistical methods and software that substantially enhances the utility and robustness of current survey methods. To achieve this, four research projects were undertaken, to develop methods for: 1) analysis of towed ... |

|
| Determining the density and distribution of cetacean (whale and dolphin) species is fundamental to understanding their basic biology, and also to monitoring and mitigating the effect of man-made impacts on their populations. However, this task is difficult because most cetacean species occur at low density and over enormous areas, and because they spend relatively little time at the surface where they can be seen using standard, visual surveys. Our primary ... |
