Tatshenshini and Alsek Rivers of Alaska
ASSESSING THE RISKOF BEAR-HUMANINTERACTION AT RIVERCAMPSITES A. GRANTMacHUTCHON, 237 CurtisRoad, Comox,BC V9M3W1, Canada, email: [email protected] DEBBIEW. WELLWOOD, P.O. Box 3217, Smithers,BC VOJ2N0, Canada,email: [email protected] Abstract: The Alsek and Tatshenshinirivers of Yukon, British Columbia, and Alaska, and the Babine River, British Columbia, are seasonally importantfor grizzly bears(Ursus arctos) and Americanblack bears(Ursus americanus). Recreationaltravelers on these rivers use riparianhabitats for camping, which could lead to bear-humaninteraction and conflict. During visits in late summer 1998-99, we used 4 qualitativeindicators to assess risk of bear-humaninteraction at river campsites: (1) seasonal habitatpotential, (2) travel concerns, (3) sensory concerns, and (4) bear sign. We then rated each campsite on a 5-class scale, relative to other campsites, for the potential to displace bears and the potential for bear-human encounters. We used these ratingsto recommendhuman use of campsites with relatively low risk.

Glaciomarine Sedimentation at the Continental Margin of Prydz Bay, East Antarctica: Implications on Palaeoenvironmental Changes During the Quaternary
Alfred-Wegener-Institut für Polar- und Meeresforschung Universität Potsdam, Institut für Erd- und Umweltwissenschaften Glaciomarine sedimentation at the continental margin of Prydz Bay, East Antarctica: implications on palaeoenvironmental changes during the Quaternary Dissertation zur Erlangung des akademischen Grades Doktor der Naturwissenschaften (Dr. rer. nat.) in der Wissenschaftsdisziplin “Geowissenschaften” eingereicht an der Mathematisch-Naturwissenschaftlichen Fakultät der Universität Potsdam von Andreas Borchers Potsdam, 30. November 2010 Das Höchste, wozu der Mensch gelangen kann, ist das Erstaunen. J. W. von Goethe Acknowledgements This dissertation would not have been possible without the support and help of numerous people to whom I would like to express my gratitude. First, I am highly indebted to PD Dr. Bernhard Diekmann for the possibility to conduct this work under his supervision and for his constant support, whenever discussion or advice was needed. I appreciated his vast expertise and knowledge of marine geology, sedimentology and Quaternary Science that he so enthusiastically shared with me, adding considerably to my experience. Besides being a full-hearted geologist, he is also a great guitarist, which I enjoyed during the past years, especially during the expeditions I had the chance to participate. I would also like to thank Prof. Dr. Hans-Wolfgang Hubberten for his general support and understanding, giving me the opportunity to broaden my knowledge of marine geology in the field. Using the infrastructure of the institute in Potsdam, Bremerhaven and on the world’s oceans has made a major contribution realizing this work. I am deeply grateful to Prof. Dr. Ulrike Herzschuh and Dr. Gerhard Kuhn who provided a large part of assistance by discussions, constructive advices and moral support. -

GSI and PBT were applied to assessment of 2019 coho salmon fisheries northern and 22 central British Columbia (BC), Canada. The catch from northern freezer troll (Area F) and ice 23 boat troll (Area F), recreational catch in Statistical Areas 3/4, the lower Skeena River test fishery 24 at Tyee, and the Heiltsuk First Nation food, social, and ceremonial fishery near Bella Bella on 25 the central coast of BC were sampled. There were 1,223 individuals successfully genotyped 26 from fishery samples and 4 parentage-based tagging identifications made. The large majority of 27 the catch in the northern troll fishery was derived from northern and central coast Conservation 28 Units. 3 29 Introduction 30 Coho salmon (Oncorhynchus kisutch) are caught in commercial, recreational, and First 31 Nations fisheries in British Columbia, and determination of the impact of these fisheries is of 32 fundamental importance to status assessment for wild populations and management of large- 33 scale hatchery production. -

Klein Vatche P. Tchakerian Mahlon Kennicutt Head of Department, Douglas Sherman December 2005 Major Subject: Geography iii ABSTRACT Investigation of Glacial Dynamics in Lambert Glacial Basin Using Satellite Remote Sensing Techniques. Jaehyung Yu, B.S., Chungnam National University; M.S., Chungnam National University Chair of Advisory Committee: Dr. Hongxing Liu The Antarctic ice sheet mass budget is a very important factor for global sea level. An understanding of the glacial dynamics of the Antarctic ice sheet are essential for mass budget estimation. Utilizing a surface velocity field derived from Radarsat three-pass SAR interferometry, this study has investigated the strain rate, grounding line, balance velocity, and the mass balance of the entire Lambert Glacier – Amery Ice Shelf system, East Antarctica. The surface velocity increases abruptly from 350 m/year to 800 m/year at the main grounding line. It decreases as the main ice stream is floating, and increases to 1200 to 1500 m/year in the ice shelf front. -

The multi-locus genotypes of all fish surveyed were provided to Dr. P. Moran of the National Marine Fisheries Service Montlake Laboratory for incorporation into the GAPS database. The number of alleles observed at a locus varied from 11 (Ots9) to 71 (Omm1070), with all loci in Hardy-Weinberg equilibrium (Table 2). -

Glacier Webquest Answer Key Questions: 1. What are glaciers? Glaciers are masses of ice made made up of snow that has accumulated over time. 2. What are the parts of a glacier? Describe the main parts. Accumulation area is part of the glacier at the highest elevation where snow falls and accumulates. Ablation area is the part of the glacier at lower elevations where melting and ablation occur. Crevasses are cracks that form in the glacier. Moraines form when glaciers carry rocky debris as they move. These can be medial (along the middle) or terminal (at the end of the glacier). 3. What qualifies an ice mass as a glacier? To classify an ice mass as a glacier, it must be more than 164 feet thick and 4. Where is Earth’s largest glacier? What is the glacier named? How large is the glacier? Earth’s largest glacier is the Lambert-Fisher Glacier in Antarctica. It’is 250 miles long, and up to 60 miles wide. 5. Where and how do glaciers form? Glaciers form in areas where snow accumulates and turns into ice. As new snow falls each year, new layers form and compress the snow turning it into ice. 6. Where on Earth are glaciers located? Why do they still exist there? Glaciers are found on most continents in areas where temperatures are cool year round and snow falls. 7. How does elevation affect glacier formation? Earth’s colder regions such as the poles and higher elevations provide conditions for the formation of glaciers where snow can accumulate over time. -
Population Structure of Lake-Type and River-Type Sockeye Salmon in Transboundary Rivers of Northern British Columbia
Journal of Fish Biology (2004) 65, 389–402 doi:10.1111/j.1095-8649.2004.00457.x,availableonlineathttp://www.blackwell-synergy.com Population structure of lake-type and river-type sockeye salmon in transboundary rivers of northern British Columbia T. D. BEACHAM*, B. MC INTOSH AND C. MACC ONNACHIE Department of Fisheries and Oceans, Pacific Biological Station, Nanaimo, B. C., V9T 6N7, Canada (Received 6 October 2003, Accepted 22 April 2004) The population structure of ‘lake-type’ and ‘river-type’ sockeye salmon Oncorhynchus nerka, primarily in transboundary rivers in northern British Columbia, was examined with a survey of microsatellite variation. Variation at 14 microsatellite loci was surveyed from c. 3000 lake-type and 3200 river-type sockeye salmon from 47 populations in six river drainages in British Columbia. The mean FST for the 14 microsatellite loci and 47 populations was 0Á068, and 0Á034 over all river-type populations. River-type sockeye salmon were more genetically diverse than lake-type sockeye salmon, with expected heterozygosity of river-type sockeye salmon 0Á72 and with an average 12Á7 alleles observed per locus, whereas expected heterozygosity of lake-type sockeye salmon was 0Á65 with and average 10Á5 alleles observed per locus. River drainage of origin was a significant unit of population structure. There was clear evidence of genetic differentiation among river-type populations of sockeye salmon from different drainages over a broad geographic range in British Columbia. # 2004 The Fisheries Society of the British Isles Key words: genetic variation; microsatellites; population structure; sockeye salmon. INTRODUCTION Sockeye salmon Oncorhynchus nerka (Walbaum) can display considerable var- iation in life history. -
