Continuous monitoring of Hawaiian volcanoes with thermal cameras
Matthew R. Patrick, Tim R. Orr, Loren Antolik, Robert Lopaka Lee, Kevan P. Kamibayashi
2014, Journal of Applied Volcanology (3)
Continuously operating thermal cameras are becoming more common around the world for volcano monitoring, and offer distinct advantages over conventional visual webcams for observing volcanic activity. Thermal cameras can sometimes “see” through volcanic fume that obscures views to visual webcams and the naked eye, and often provide a much clearer...
Upwelling rebound, ephemeral secondary pycnoclines, and the creation of a near-bottom wave guide over the Monterey Bay continental shelf
Olivia M. Cheriton, Erika E. McPhee-Shaw, Curt D. Storlazzi, Kurt J. Rosenberger, William J. Shaw, Ben Y. Raanan
2014, Geophysical Research Letters (41) 8503-8511
Several sequential upwelling events were observed in fall 2012, using measurements from the outer half of the continental shelf in Monterey Bay, during which the infiltration of dense water onto the shelf created a secondary, near-bottom pycnocline. This deep pycnocline existed in concert with the near-surface pycnocline and enabled the...

Fred Amidon, Richard J. Camp, Ann P. Marshall, Thane K. Pratt, Laura Williams, Paul Radley, Justine B. Cruz
2014, Bird Conservation International (24) 505-517
The island of Aguiguan is part of the Mariana archipelago and currently supports populations of four endemic species, including one endemic genus, Cleptornis. Bird population trends since 1982 were recently assessed on the neighbouring islands of Saipan, Tinian, and Rota indicating declines in some native species. Point-transect surveys were conducted in...
Pedological and geological relationships with soil lichen and moss distribution in the eastern Mojave Desert, CA, USA
Jayne Belnap, David M. Miller, David R. Bedford, Susan L. Phillips
2014, Journal of Arid Environments (106) 45-57
Biological soil crusts (biocrusts) are ubiquitous in drylands globally. Lichens and mosses are essential biocrust components and provide a variety of ecosystem services, making their conservation and management of interest. Accordingly, understanding what factors are correlated with their distribution is important to land managers. We hypothesized that cover would be...

2014, Professional Paper 1708-G.7
Natural gases and associated crude oils in the “Clinton” sandstone, Medina Group sandstones, and equivalent Tuscarora Sandstone in the northern Appalachian basin are part of a regional, continuous-type or basin-centered accumulation. The origin of the hydrocarbon charge to regional continuoustype accumulations is poorly understood. We have analyzed the molecular and...
