Geological Field Guide To The Cedar Point Biological Station, Keith County, Nebraska, Robert F. Diffendal Jr., Roger K. Pabian
Geological Field Guide To The Cedar Point Biological Station, Keith County, Nebraska, Robert F. Diffendal Jr., Roger K. Pabian
School of Natural Resources: Faculty Publications
This field guide was produced by staff members of the Conservation and Survey Division of the University of Nebraska originally in 1979 at the request of Dr. Brent Nickol, former Director of the Cedar Point Biological Station. It is an introduction to the geologic history and paleoecology of the Cedar Point area intended for students, staff, and other persons using the camp. This revision has been made some 15 years after the first version to reflect changes in ideas resulting from new data collected during that time.
Users of this guide should take care when studying the rock exposures described …

Monthly mean maximum and minimum temperatures for over 50% (10%) of the Northern (Southern) Hemisphere landmass, accounting for 37% of the global landmass, indicate that the rise of the minimum temperature has occurred at a rate three times that of the maximum temperature during the period 1951-90 (0.84°C versus 0.28°C). The decrease of the diumal temperature range is approximately equal to the increase of mean temperature. The asymmetry is detectable in all seasons and in most of the regions studied.

Reflectance spectra from 400 to 750 nm were measured in Lake Kinneret, when low phytoplankton stock prevailed, with chlorophyll concentrations from 3.1 to 7.3 μg/l. Algorithms for estimation of chlorophyll (CHL) concentration were devised using reflectances in the blue and green region of the spectrum and natural solar induced fluorescence. The fluorescence was calculated either from the reflectance height above a baseline drawn between 650 and 715 nm or between 670 and 730 nm, and also from the sum of reflectance above the base line through 670 and 730 nm. This paper presents experimental evidence showing that fluorescence can be …
Reflectance Models For Quantifying Chlorophyll In Inland Waters, Anatoly A. Gitelson
Reflectance Models For Quantifying Chlorophyll In Inland Waters, Anatoly A. Gitelson
School of Natural Resources: Faculty Publications
To develop the models for chlorophyll (CHL) estimation, the nature of a peak near 700 nm on the reflectance spectrum of water should be investigated. Simultaneous measurements of the reflectance spectra from 400 to 750 nm and relevant water quality constituent concentrations were carried out. A shift of the peak position and an increase of the peak magnitude, when chlorophyll concentration increased, were observed. The relationships of the magnitude and position of the peak to chlorophyll-a, were applied to several independent data sets. The parameters of the peak can be used as precise indicators of CHL content in inland waters.
