Habitat comparisons and productivity in nesting common terns on the mid-Atlantic coast
R.M. Erwin, D. C. Smith
1985, Colonial Waterbirds (8) 155-165
Nesting Common Terns (Sterna hirundo) were studied at a number of barrier beaches and small islands of tidal salt marsh in New Jersey and the Eastern Shore of Maryland-Virginina from 1980 through 1982. Data were collected on clutch sizes, nest spacing, and nesting success. The principal null hypothesis tested was...

Leaching characteristics of ash from the May 18, 1980, eruption of Mount St. Helens Volcano, Washington

1982, Open-File Report 82-987
Leaching of freshly erupted air-fall ash, unaffected by rain, from the May 18, 1.980,eruption of Mount St. Helens volcano, Washington, shows that Ca 2+, Na+, Mg+, SO4 2-, and Cl- are the predominant chemical species released on first exposure of the ash to water. Extremely high correlation of Ca with...
Water-soluble material on aerosols collected within volcanic eruption clouds

1982, Journal of Geophysical Research - Oceans (87) 4963-4972
In February and March of 1978, filter samplers mounted on an aircraft were used to collect the aerosol fraction of the eruption clouds from three active Guatemalan volcanoes (Fuego, Pacaya, and Santiaguito). The samples were collected on Teflon (Fluoropore) filters with a nominal pore diameter of 0.5μm. The mass of...
Leachability of uranium and other elements from freshly erupted volcanic ash

1982, Journal of Volcanology and Geothermal Research (13) 1-30
A study of leaching of freshly erupted basaltic and dacitic air-fall ash and bomb fragment samples, unaffected by rain, shows that glass dissolution is the dominant process by which uranium is initially mobilized from air-fall volcanic ash. Si, Li, and V are also preferentially mobilized by glass dissolution. Gaseous transfer...
Common tern colonies along the mid-Atlantic coast. I. Nestling chronology

1. Sixteen Common Tern colonies in Rhode Island, New Jersey, Virginia, and North Carolina were studied from May through July 1980 by four investigators. Nests were marked during egg laying and were monitored every 5-7 days until fledging of young. 2. Results from 1980 indicate that ambient temperature differences...

The flow mechanism in the Chalk based on radio-isotope analyses of groundwater in the London Basin
R.A. Downing, F.J. Pearson, D. B. Smith
1979, Journal of Hydrology (40) 67-83
14C analyses of groundwaters from the Chalk of the London Basin are re-interpreted and the age of the groundwater is revised. Radio-isotope analyses are used to examine the flow mechanism in the aquifer. The evidence supports the view that a network of micro-fissures and larger intergranular pores in the matrix...
The age of groundwater in the Lincolnshire Limestone, England and its relevance to the flow mechanism
R.A. Downing, D. B. Smith, F.J. Pearson, R.A. Monkhouse, R.L. Otlet
1977, Journal of Hydrology (33) 201-216
Groundwater samples from the Lincolnshire Limestone have been analysed for tritium, radiocarbon, and the stable-isotope ratios 13C12C">13C12C, 18O16O">18O16O and D/H. The age of the water increases in a downgradient direction below overlying confining deposits and reaches a maximum age greater than...
