Thomas L. Wright, Fred W. Klein
2014, Professional Paper 1806
This publication summarizes the evolution of the internal plumbing of Kīlauea Volcano on the Island of Hawaiʻi from the first documented eruption in 1790 to the explosive eruption of March 2008 in Halemaʻumaʻu Crater. For the period before the founding of the Hawaiian Volcano Observatory in 1912, we rely on...

Gary L. Krapu, David A. Brandt, Paul J. Kinzel, Aaron T. Pearse
2014, Wildlife Monographs (189) 1-41
We conducted a 10-year study (1998–2007) of the Mid-Continent Population (MCP) of sandhill cranes (Grus canadensis) to identify spring-migration corridors, locations of major stopovers, and migration chronology by crane breeding affiliation (western Alaska–Siberia [WA–S], northern Canada–Nunavut [NC–N], west-central Canada–Alaska [WC–A], and east-central Canada–Minnesota [EC–M]). In the Central Platte River Valley...

Spatial extent and dissipation of the deep chlorophyll layer in Lake Ontario during the Lake Ontario lower foodweb assessment, 2003 and 2008
J. M. Watkins, Brian M. Weidel, L. G. Rudstam, K. T. Holek
2014, Aquatic Ecosystem Health & Management (18) 18-27
Increasing water clarity in Lake Ontario has led to a vertical redistribution of phytoplankton and an increased importance of the deep chlorophyll layer in overall primary productivity. We used in situ fluorometer profiles collected in lakewide surveys of Lake Ontario in 2008 to assess the spatial extent and intensity of...

Oliver S. Boyd, Chris H. Cramer
2014, Bulletin of the Seismological Society of America (104) 1709-1722
A new macroseismic intensity prediction equation is derived for the central and eastern United States and is used to estimate the magnitudes of the 1811–1812 New Madrid, Missouri, and 1886 Charleston, South Carolina, earthquakes. This work improves upon previous derivations of intensity prediction equations by including additional intensity data, correcting...

Time-averaged discharge rate of subaerial lava at Kīlauea Volcano, Hawai‘i, measured from TanDEM-X interferometry: Implications for magma supply and storage during 2011-2013
Michael P. Poland
2014, Journal of Geophysical Research B: Solid Earth (119) 5464-5481
Differencing digital elevation models (DEMs) derived from TerraSAR add-on for Digital Elevation Measurements (TanDEM-X) synthetic aperture radar imagery provides a measurement of elevation change over time. On the East Rift Zone (EZR) of Kīlauea Volcano, Hawai‘i, the effusion of lava causes changes in topography. When these elevation changes are summed...
Late Holocene sea level variability and Atlantic Meridional Overturning Circulation
Thomas M. Cronin, Jesse R. Farmer, R. E. Marzen, E. Thomas, J.C. Varekamp
2014, Paleoceanography (29) 765-777
Pre-twentieth century sea level (SL) variability remains poorly understood due to limits of tide gauge records, low temporal resolution of tidal marsh records, and regional anomalies caused by dynamic ocean processes, notably multidecadal changes in Atlantic Meridional Overturning Circulation (AMOC). We examined SL and AMOC variability along the eastern United...
Identifying dominant controls on hydrologic parameter transfer from gauged to ungauged catchments: a comparative hydrology approach
R. Singh, S.A. Archfield, T. Wagener
2014, Journal of Hydrology (517) 985-996
Daily streamflow information is critical for solving various hydrologic problems, though observations of continuous streamflow for model calibration are available at only a small fraction of the world’s rivers. One approach to estimate daily streamflow at an ungauged location is to transfer rainfall–runoff model parameters calibrated at a gauged (donor)...

2014, Earth and Planetary Science Letters (401) 47-56
The U.S. southwest has a limited water supply and is predicted to become drier in the 21st century. An improved understanding of factors controlling moisture sources and availability is aided by reconstruction of past responses to global climate change.

Decreased atmospheric sulfur deposition across the southeastern U.S.: When will watersheds release stored sulfate?
Karen C. Rice, Todd M. Scanlon, Jason A. Lynch, Bernard J. Cosby
2014, Environmental Science & Technology (48) 10071-10078
Emissions of sulfur dioxide (SO2) to the atmosphere lead to atmospheric deposition of sulfate (SO42-), which is the dominant strong acid anion causing acidification of surface waters and soils in the eastern United States (U.S.). Since passage of the Clean Air Act and its Amendments, atmospheric deposition of SO2 in...
