Miocene to recent dust record from the Southwest Pacific Ocean (2008)

Stancin, Andrea M, Gleason, James D, Hovan, Steven A, Rea, David K, Owen, Robert M, Moore, Theodore C, ...

A 14-meter long pelagic clay core recovered at Marlin Rise (40°00.531'S, 154°2.601'W; 4775 m water depth) in the Southwest Pacific Basin contains a record of eolian dust deposited since the early...

Influence of Snow and Ice Crystal Formation and Accumulation on Mercury Deposition to the Arctic (2008)

Douglas, Thomas A, Sturm, Matthew, Simpson, William R, Blum, Joel D, Alvarez-Aviles, Laura, Keeler, Gerald J, ...

Mercury is deposited to the Polar Regions during springtime atmospheric mercury depletion events (AMDEs) but the relationship between snow and ice crystal formation and mercury deposition is not well...

Isotope record of Nd-Sr-Pb in deep sea sediments from the Pacific (Table 2) (2006)

Stancin, Andrea M, Gleason, James D, Rea, David K, Owen, Robert M, Moore, Theodore C, Blum, Joel D, ...

Pelagic clay of the east-central Pacific province is shown to be a mixture of three primary detrital components, reflecting continental source areas in Asia, North America, and Central and South...

Concentrations of Ti, Fe, and Al and radiogenic isotope data for sediments of ODP Leg 177 (2006)

Latimer, Jennifer C, Filippelli, Gabriel M, Hendy, Ingrid L, Gleason, James D, Blum, Joel D

Identifying terrigenous sources in deep-sea sediments may reveal temporal trends in paleocirculation and the relative role of eolian, upwelled, and hemipelagic Fe sources to surface waters. Bulk...

Dissolution of wollastonite during the experimental manipulation of Hubbard Brook Watershed 1 (2004)

Peters, Stephen C., Blum, Joel D., Driscoll, Charles T., Likens, Gene E.

Powdered and pelletized wollastonite (CaSiO 3 ) was applied to an 11.8 ha forested watershed at the Hubbard Brook Experimental Forest (HBEF) in northern New Hampshire, U.S.A. during October of 1999....

EGGSHELL CHARACTERISTICS AND CALCIUM DEMANDS OF A MIGRATORY SONGBIRD BREEDING IN TWO NEW ENGLAND FORESTS (2001)

E. HANK TALIAFERRO, RICHARD T. HOLMES, JOEL D. BLUM

Calcium has been reported to be a limiting nutrient for eggshell production in birds living in areas of northern Europe suffering from heavy acid deposition. To investigate whether calcium might be...

Determining the sources of calcium for migratory songbirds using stable strontium isotopes (2001)

Blum, Joel D., Holmes, Richard T., Taliaferro, E. Hank

We investigated natural variations in the stable isotopic composition of strontium (a surrogate for calcium) in the bones of a single species of breeding migratory songbird, as well as in their...

Changes in Sr/Ca, Ba/Ca and 87Sr/86Sr ratios between trophic levels in two forest ecosystems in the northeastern U.S.A. (2000)

Blum, Joel D., Taliaferro, E. Hank, Weisse, Marie T., Holmes, Richard T.

The variability and biologicalfractionation of Sr/Ca, Ba/Ca and 87 Sr/ 86 Srratios were studied in a soil–plant–invertebrate–bird food chain in two forested ecosystems withcontrasting calcium...

Algal blooms reduce the uptake of toxic methylmercury in freshwater food webs

Pickhardt, Paul C., Folt, Carol L., Chen, Celia Y., Klaue, Bjoern, Blum, Joel D.

Mercury accumulation in fish is a global public health concern, because fish are the primary source of toxic methylmercury to humans. Fish from all lakes do not pose the same level of risk to...
