Tri-tube Freeze-core Procedure for Sampling Stream Gravels
Autor: Barry H. Reid, Frederick B. Lotspeich
Publikováno v: The Progressive Fish-Culturist. 42:96-99
This paper presents a description of equipment and methods for sampling streambed gravels by using a three-tube array of cryogenic samplers and compares the tri-tube freeze-core sampler with single-tube freeze-core samplers.

WATERSHEDS AS THE BASIC ECOSYSTEM: THIS CONCEPTUAL FRAMEWORK PROVIDES A BASIS FOR A NATURAL CLASSIFICATION SYSTEM
Autor: Frederick B. Lotspeich
Publikováno v: Journal of the American Water Resources Association. 16:581-586
A scheme is outlined to classify watersheds as ecosystems, based on their natural attributes. Two physical factors of the environment, climate and geology, are selected as state factors. Climate is the master factor that supplies energy and water to

Effects of Forest Fertilization on Two Southeast Alaska Streams
Autor: Frederick B. Lotspeich, William R. Meehan, Ernst W. Mueller
Publikováno v: Journal of Environmental Quality. 4:50-55
Four streams in southeast Alaska were studied to determine the effects of forest fertilization with urea on basic productivity and water quality. An initial, short-term increase in ammonia-nitrogen was observed in the treated streams, and nitrate-nit

An Integrated Land-Aquatic Classification System
Autor: William S. Platts, Frederick B. Lotspeich
Publikováno v: North American Journal of Fisheries Management. 2:138-149
Responsible resource use depends largely on accurate inventories, which implies the creation of a land classification system because an inventory without classification is mainly an unorganized list. In this paper we develop a simple classification s

Vegetation as a Soil-Forming Factor on the Quillayute Physiographic Unit in Western Clallam County, Washington
Autor: Rose Okazaki, Frederick B. Lotspeich, Henry W. Smith, Jack B. Secor
Publikováno v: Ecology. 42:53-68
Several treeless areas (i.e., prairies) in an otherwise heavily forested locale are known in Clallam County, on the Olympic Peninsula in northwestern Washington (Wheeting 1936, Fowler and Wheeting 1941). These persistent elements of the landscape, in

Quality of Waters From Playas on the Southern High Plains
Autor: Frederick B. Lotspeich, Oliver R. Lehman, Victor L. Hauser
Publikováno v: Water Resources Research. 5:48-58
An estimated 2.5 to 3.0 million acre-feet of runoff water accumulate annually in playas on the Southern High Plains. This large water resource should be developed for more intensive use; however, past lack of knowledge about its quality has impeded p
