Kirwan: [PowerPoint Presentation] My report this morning will be devoted primarily to the Academic Plan and its importance not only to Ohio State, but also to the State of Ohio and its citizens. First, however, I feel it is important to report briefly on the campus area disturbances in the neighborhood east of High Street following the Michigan football game. Throughout that night, some 125 fires were set, four automobiles were badly damaged or demolished, and many car windows were broken. One student was stabbed as he tried to get people to leave a party in his apartment. Thankfully, he is recovering. Eleven students were arrested on a variety of charges and several more may be arrested before the Columbus police close this matter.

    Lake Erie Watersnake Recovery Plan (Nerodia sipedon insularum) September 2003 Department of the Interior U. S. Fish and Wildlife Service Great Lakes-Big Rivers Region (Region 3) Fort Snelling, MN ii DISCLAIMER Recovery plans delineate reasonable actions which are believed to be required to recover and/or protect listed species. Plans are published by the U.S. Fish and Wildlife Service, sometimes prepared with the assistance of recovery teams, contractors, State agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans do not necessarily represent the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and completion of recovery tasks. LITERATURE CITATION U.S. Fish and Wildlife Service. 2003.

  • Geophysical Methods in Impact Crater Hunting – Case Summanen
    Geophysical methods in impact crater hunting – Case Summanen L.J. Pesonen1, S. Hietala2*, J. Plado3, T. Kreitsmann3, J. Lerssi2, and J. Nenonen2 1 Solid Earth Geophysics Laboratory, Physics Department, University of Helsinki, Finland 2 Geological Survey of Finland, Kuopio, Finland 3 Department of Geology, University of Tartu, Estonia, *correspondence: [email protected] Abstract Impact cratering is a ubiquitous process in our solar system affecting all planetary surfaces throughout geologic time. On Earth, there are currently 190 confirmed impact structures, which are distributed unevenly. The Fennoscandian Shield houses 17 % of them. The large amount of impact structures makes Fennoscandia one of the most densely cratered terrains on Earth. A dozen (12) impact structures have been discovered in Finland. The latest discovery, Lake Summanen is located in Central Finland, about 9 km southeast of city Saarijärvi. An impact generated structure was first hinted by airborne geophysical mapping by the Geological Survey of Finland in the early 2000`s (Lerssi et al., 2007) that revealed a circular ~2.6 km wide striking aeroelectromagnetic resistivity anomaly. Recent studies in 2017-2018 confirmed its impact origin based on the findings of shatter cone-bearing rocks and the identification of planar deformation features in quartz. 1. INTRODUCTION Summanen impact crater (62°39’00’’N, 25°22’30’’E) is located within the Paleoproterozoic Central Finland Granite Belt and is covered with the Lake Summanen. The lake is somewhat elliptical (8 km x 9 km x 4 km) in shape, whereby the longest axis extends in NW–SE direction due to the erosional influence of the latest (Weichselian) glaciation.

  • Lake Erie Islands
    Number of Lake Erie Islands in Ohio: 15* 2010 Island Population: 945 (not including Johnson’s Island) Number of Access Sites: South Bass Island: 13 Middle Bass Island: 4 North Bass Island: 3 Kelleys Island: 6 Number of Right-of-Way Sites: 1 Miles of Publicly Accessible Coast: 9.7 miles Lake Erie Islands Ohio has over a dozen natural islands in Lake Erie’s Western Basin. The Lake Erie Islands range in size from miniscule rock outcroppings that disappear and reappear with the rise and fall of the lake’s water levels, to larger inhabited land masses. Ohio’s largest island is Kelleys Island (2,837 acres), followed by South Bass (1,523 acres), Middle Bass (771 acres) and North Bass (677 acres) islands. The remaining Lake Erie Islands in Ohio are all smaller than 100 acres. Johnson’s Island, located in Sandusky Bay, is 300 acres. Canada’s Pelee Island (10,330 acres) is the largest island in Lake Erie. Ohio’s islands are renowned for their natural resources, recreational opportunities, cultural attractions and charm. South Bass Island is the southernmost and most developed of the three Bass Islands. It is located in Ottawa County approximately three miles north of Catawba Point. In the 1850s, the grape-growing and wine-making industries began to flourish, which helped establish the island as a popular vacation destination. The 625-room Hotel Victory was built in 1892. When it opened it was the largest resort hotel in the country and featured the first co-ed swimming pool. Fire destroyed the hotel in 1919.
