Lighthouse Presque Isle, Mich.

attached letter: Dear Professor Lorch: At the suggestion of the July 31, 1953 Newsletter of the Michigan Historical Society I am sending you two photoes [sic] of the old lighthouse and adjoining building on Presque Isle, Michigan located on the shore of Huron lake, supposedly the oldest lighthouse on the Great Lakes. It is owned by Mr. F. B. Stebbins, 326 N. Capital, Lansing, Michigan. When through using the photos I would appreciate your returning them directly to him. The following information was given to me by Mr. Stebbins: Built in 1840, through a congressional appropriation of $5,000.- in Presque Isle county, described as, "Where a portage of 200 yards would save 4 miles of canoe trip." Jefferson Davis after graduation from West Point, was supposed to have built it. (According to careful historical investigation, this is not true. There is an article about this controversy in some back number of the Michigan History magazine. Mr. Stebbins feels very strongly about his. He prefers the legend, it sounds bigger). Francis Burgoyne Stebbins purchased from his Uncle Bliss Stebbins in 1930, who bought the property in 1930 from General Duffield of Dteoirt [sic], who had purchased it from the government a short time previously. This light-house was abandone [sic] upon the completion of a new lighthouse in 1872, one mile north from the present location. Adjoining house was used as a summer home. Condition restored in 1936. Lighthouse towe [sic] walls 3 feet thick with handhewn circular stone steps to the top. Signed, Lee H. Gregory

Characteristics, home ranges and population estimates of narwhals (Monodon monoceros) around Baffin Island

Twenty-one narwhals tagged in 2003 and 2004 in Admiralty Inlet showed a different summer distributional pattern than previous narwhal-tracking studies from Somerset Island, Eclipse Sound and Melville Bay. The migration of the narwhals tracked from Admiralty Inlet moved out through Lancaster Sound 15 days earlier (P <0.0001) than the narwhals summering around Eclipse Sound, whereas the Admiralty Inlet narwhals reached the mouths of Eclipse Sound 18 days later (P <0.0001) than the Eclipse Sound summering population. The winter range of the Admiralty Inlet narwhals overlapped with the winter range of narwhals from Melville Bay and Eclipse Sound in central southern Baffin Bay and Northern Davis Strait, but not with the winter range of narwhals from Somerset Island that wintered further north. Distribution size of range, and population size did not appear to be related. An example of considerable year to year variation between area of summer and winter distribution in the 2 years was believed to be related to the sample size and number of pods of whales tagged, rather than to differences in sex or age classes.

An update of observed stratospheric temperature trends

An updated analysis of observed stratospheric temperature variability and trends is presented on the basis of satellite, radiosonde, and lidar observations. Satellite data include measurements from the series of NOAA operational instruments, including the Microwave Sounding Unit covering 1979–2007 and the Stratospheric Sounding Unit (SSU) covering 1979–2005. Radiosonde results are compared for six different data sets, incorporating a variety of homogeneity adjustments to account for changes in instrumentation and observational practices. Temperature changes in the lower stratosphere show cooling of 0.5 K/decade over much of the globe for 1979–2007, with some differences in detail among the different radiosonde and satellite data sets. Substantially larger cooling trends are observed in the Antarctic lower stratosphere during spring and summer, in association with development of the Antarctic ozone hole. Trends in the lower stratosphere derived from radiosonde data are also analyzed for a longer record (back to 1958); trends for the presatellite era (1958–1978) have a large range among the different homogenized data sets, implying large trend uncertainties. Trends in the middle and upper stratosphere have been derived from updated SSU data, taking into account changes in the SSU weighting functions due to observed atmospheric CO2 increases. The results show mean cooling of 0.5–1.5 K/decade during 1979–2005, with the greatest cooling in the upper stratosphere near 40–50 km. Temperature anomalies throughout the stratosphere were relatively constant during the decade 1995–2005. Long records of lidar temperature measurements at a few locations show reasonable agreement with SSU trends, although sampling uncertainties are large in the localized lidar measurements. Updated estimates of the solar cycle influence on stratospheric temperatures show a statistically significant signal in the tropics (30N–S), with an amplitude (solar maximum minus solar minimum) of 0.5 K (lower stratosphere) to 1.0 K (upper stratosphere).
