Scale-dependent correlation of seabirds with schooling fish in a coastal ecosystem
Davod C. Schneider, John F. Piatt
1986, Marine Ecology Progress Series (32) 237-246
The distribution of piscivorous seabirds relative to schooling fish was investigated by repeated censusing of 2 intersecting transects in the Avalon Channel, which carries the Labrador Current southward along the east coast of Newfoundland. Murres (primarily common murres Uria aalge), Atlantic puffins Fratercula arctica, and schooling fish (primarily capelin Mallotus...
What won't Turnstones eat?
Robert E. Gill Jr.
1986, British Birds (79) 402-403
The Turnstone Arenaria interpres probably has one of the most varied diets of any wader species. Besides the 'normal' foods taken (see, e.g., Prater 1972, Nettleship 1973, Jones 1975), a considerable variety of 'unusual' foods and feeding behaviours has also been reported. Items taken include soap, gull excrement, dog food,...
Transport of chloride ion in a water-unsaturated soil exhibiting anion exclusion
Ronald V. James, Jacob Rubin
1986, Soil Science Society of America Journal (50) 1142-1149
Miscible displacement techniques were used to create Cl- concentration profiles in unsaturated laboratory columns of Delhi sand (Typic Xeropsamments), each having a nearly uniform water content. The three steady flow rates used resulted in three different, average water contents. Chloride concentrations near the top of the column were smaller and...
Living with the earthquake risk
A. M. Rogers
1986, Earthquakes & Volcanoes (USGS) (18) 113-121
The principal hazards from earthquakes are surface faulting, ground failure, and ground shaking. In coastal areas tsunamis, or seismic sea waves, also are a potential hazard. We will consider each of these hazards briefly to assess their possible effects on the structures of man.  ...
Meteoroids and impact craters
Henry Spall
1986, Earthquakes & Volcanoes (USGS) (18) 84-89
On a clear night scores of meteoroids streak across the sky. they leave light paths we call meteors or shooting stars as the Earth is showered with debris from distant parts of the solar system. When these meteoroids hit the Earth (as meteorites) they range in size from pebbles to...
The Pacific tsunami warning system
G. Pararas-Carayannis
1986, Earthquakes & Volcanoes (USGS) (18) 122-130
Of all natural disasters, tsunamis are among the most terrifying and complex phenomena, responsible for great loss of lives and vast destruction of property. Enormous destruction of coastal communities has taken place throughout the world by such great waves since the beginning of recorded history. The impact of tsunamis on human...
Earthquakes, January-February 1986
W. J. Person
1986, Earthquakes & Volcanoes (USGS) (18) 235-237
The first two months of the year were somewhat quiet seismically speaking. There were no major earthquakes (7.0-7.9) but one death was caused by an earthquake in Peru. In the United States a magntidue 4.9 earthquake in Ohio on January 31 caused some minor injuries and was felt in eleven states,...
Earthquakes, March-April 1986
W. J. Person
1986, Earthquakes & Volcanoes (USGS) (18) 237-239
There was one major earthquake (7.0-7.9) in Mexico on April 30, during this reporting period. Earthquake-related deaths were reported in India and Peru. In the United States, California experienced three widely felt earthquakes. ...
Halley’s comet; a benevolent visitor to Earth
H. Spall
1986, Earthquakes & Volcanoes (USGS) (18) 98-102
In late 1985 and early 1986 a comet was visible to the Earth that has been observed for over 2000 years. One of the most famous of celestial visitors, Comet Halley appeared last in 1910 and will not be seen again until the year 2061. the comet has been the...
New theories about ancient extinctions
H. Spall
1986, Earthquakes & Volcanoes (USGS) (18) 90-92
The abrupt disappearance of all the dinosaurs about 65 million years ago, along with perhaps half the plant species and other animals, has been one of the great geological mysteries. Clues to the cause of these extinctions have been scarce and open to many interpretations. But all this may be changing....
Volcanoes and atmospheres; catastrophic influences on the planets
S. W. Kieffer
1986, Earthquakes & Volcanoes (USGS) (18) 76-83
For a rare and brief instant in geologic time, we can imagine that the sulfurous, chromatic surface of Io (one of the satellites of Jupiter) lies quiet. Perhaps stars glisten brilliantly through the tenuous nigh sky. Here and there, thick icy fogs enshroud fumaroles where sulfur dioxide leaks from the...
The Tunguska comet or the great Siberian mystery explosion of 1908
H. Spall
1986, Earthquakes & Volcanoes (USGS) (18) 93-97
It is dawn on a June morning in Siberia in 1908. The sky is cloudless, but even in summer this part of Russia the cold at dawn takes your breath away. Fur-clad nomads are beginning to herd their sheep and goats towards lush grazing on the banks of the river-one...
Cooperative earthquake research between the United States and the People’s Republic of China
D. P. Russ, L.E. Johnson
1986, Earthquakes & Volcanoes (USGS) (18) 138-140
Cooperative research by scientists of the United States and the People's Republic of China (PRC) has resulted in important new finding concerning the fundamental characteristics of earthquakes and new insight into mitigating earthquake hazards. Much of the research is being conducted under the U.S State Department Protocol for Scientific and...
Land subsidence
T.L. Holzer
1986, Earthquakes & Volcanoes (USGS) (18) 131-137
In November 1966, sixty percent of Venice, Italy, is inundated by a storm surge that causes waters in the Venetian lagoon to rise more than 6 feet. On December 28, 1971, a janitor at the Washington Elementary School in Johnston City, Illinois, discovers sever cracking of the school. In January...
Vegetation and terrain mapping in Alaska using Landsat MSS and digital terrain data
Mark Shasby, David M. Carneggie
1986, Photogrammetric Engineering and Remote Sensing (52) 779-786
During the past 5 years, the U.S. Geological Survey's (USGS) Earth Resources Observation Systems (EROS) Data Center Field Office in Anchorage, Alaska has worked cooperatively with Federal and State resource management agencies to produce land-cover and terrain maps for 245 million acres of Alaska. The need for current land-cover information...
Marine birds
Anthony R. DeGange, Gerald A. Sanger
Donald W. Hood, Steven T. Zimmerman, editor(s)
1986, Book chapter, The Gulf of Alaska: Physical environment and biological resources
In this chapter we review existing knowledge of marine birds in the Gulf of Alaska. Three estuarine systems in the Gulf provide critical habitat for migratory shorebirds and waterfowl: 1) the Stikine River Delta, 2) Cook Inlet, and 3) the Copper River Delta. Over 20 million waterbirds are estimated to...
High-energy nearshore processes
1986, Eos, Transactions, American Geophysical Union (67) 1369-1371
The problem of shoreline erosion has become a matter of much interest in the recent press. To some extent this interest has been driven by the slow rise in sea level that has lent an air of inevitabilty to matters. However, the discussions certainly become more focused by the approach...
