Available in PDF, EPUB and Kindle. Book excerpt: Acoustic monitoring is an effective means by which to study cetaceans, such as beluga whales (Delphinapterus leucas), and can be useful in determining habitat preference and geographic variation among populations. Acoustic monitoring data were analyzed using a combination of automated detection and manual analysis to determine habitat preference of Cumberland Sound beluga in their summering range. Belugas were primarily detected in the northernmost site in Clearwater Fiord, with diel variation in call patterns at two separate sites in different years. No correlation was evident between tidal cycles and beluga detections. A second study examined geographic variation in simple contact calls (SCC's) among four Canadian beluga populations. Results indicate variation in the measured parameters (duration, peak frequency and pulse repetition rate) among four populations and align with genetic variation previously described in the literature. These findings provide important information necessary for the conservation and management of beluga populations in Canada.

Available in PDF, EPUB and Kindle. Book excerpt: Deep learning (DL), mainly composed of deep and complex neural networks such as recurrent network and convolutional network, is an emerging research branch in the field of artificial intelligence and machine learning. DL revolution has a far-reaching impact on all scientific disciplines and every corner of our lives. With continuing technological advances, marine science is entering into the big data era with the exponential growth of information. DL is an effective means of harnessing the power of big data. Combined with unprecedented data from cameras, acoustic recorders, satellite remote sensing, and large model outputs, DL enables scientists to solve complex problems in biology, ecosystems, climate, energy, as well as physical and chemical interactions. Although DL has made great strides, it is still only beginning to emerge in many fields of marine science, especially towards representative applications and best practices for the automatic analysis of marine organisms and marine environments. DL in nowadays' marine science mainly leverages cutting-edge techniques of deep neural networks and massive data which collected by in-situ optical or acoustic imaging sensors for underwater applications, such as plankton classification and coral reef detection. This research topic aims to expand the applications of marine science to cover all aspects of detection, classification, segmentation, localization, and density estimation of marine objects, organisms, and phenomena.

This book was released on 2018-12-14 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Law Library presents the complete text of the Endangered and Threatened Species - Designation of Critical Habitat for Cook Inlet Beluga Whale (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition). Updated as of May 29, 2018 We, the National Marine Fisheries Service (NMFS), designate critical habitat for the Cook Inlet beluga whale (Delphinapterus leucas) distinct population segment (DPS) under the Endangered Species Act (ESA). Two areas are designated, comprising 7,800 square kilometers (3,013 square miles) of marine habitat. In developing this final rule we considered public and peer review comments, as well as economic impacts and impacts to national security. We have decided in the final rule to exclude the Port of Anchorage (POA) in consideration of national security interest. Additionally, consistent with the proposed rule, portions of military lands were determined to be ineligible for designation as critical habitat. We solicited comments from the public on all aspects of the proposed rule, and conducted four public hearings on the action. Along with the proposed rule, we published a draft economic impacts analysis, entitled "Draft RIR/4(b)(2) Preparatory Assessment/IFRA for the Critical Habitat Designation of Cook Inlet Beluga Whale." This economic analysis has been completed to support the final designation. See "Final RIR/4(b)(2) Preparatory Assessment/FRFA for the Critical Habitat Designation of Cook Inlet Beluga Whale" for a discussion of these topics. This ebook contains: - The complete text of the Endangered and Threatened Species - Designation of Critical Habitat for Cook Inlet Beluga Whale (US National Oceanic and Atmospheric Administration Regulation) (NOAA) (2018 Edition) - A dynamic table of content linking to each section - A table of contents in introduction presenting a general overview of the structure

This book was released on 1985 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hunts of beluga whales were monitored in Clearwater Fiord during the summers of 1982, 1983 and 1984 and a spring floe edge hunt of beluga and narwhal in Cumberland Sound was monitored in May of 1983. Hunting techniques were recorded and biological samples and measurements were collected when possible. The report presents a summary of information collected during these hunts.

This book was released on 2005 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the peer review meeting summarized in this report was to proceed with a recovery potential assessment for 4 beluga populations designated as at risk under the Species at Risk Act (SARA). The 4 beluga populations are the Cumberland Sound, the Saint Lawrence Estuary, the Ungava Bay and the Eastern Hudson Bay populations. The 1st part of the meeting focussed on the development of interim descriptions of the biological properties of suitable recovery targets and recovery times that could be applied to beluga populations of concern. The 2nd part of the meeting addressed the recovery potential assessment for each beluga population.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents proceedings of a workshop to review four presentations and draft a stock status report on Cumberland Sound belugas, and to start drafting a recovery strategy for that beluga population. The four presentations summarized recent research on seasonal movements & habitat use, genetic & contaminant profiles, population size & trend, and population modelling & risk analysis of Cumberland Sound belugas. These presentations provided pertinent information and served as a basis for discussion to aid in drafting the stock status report.
