Erosion by rivers and transport pathways in the ocean: A provenance tool using 40Ar--39Ar incremental heating on fine-grained sediment

Creator:: VanLaningham, Sam, Duncan, Robert A., and Pisias, Nicklas G.
Abstract:: We use Ar-40-Ar-39 incremental heating to fingerprint bulk fluvial sediment entering the northeast Pacific Ocean, with the long-term intent of tracking sediment source and transport changes from the terrestrial system to the marine environment through time. We show reproducible age spectra from individual rivers accounting for the majority of sediment...

Urbanization causes increased cloud base height and decreased fog in coastal Southern California

Creator:: Williams, A. Park, Schwartz, Rachel E., Iacobellis, Sam, Seager, Richard, Cook, Benjamin I., Still, Christopher J., Husak, Gregory, and Michaelsen, Joel
Abstract:: Subtropical marine stratus clouds regulate coastal and global climate, but future trends in these clouds are uncertain. In coastal Southern California (CSCA), interannual variations in summer stratus cloud occurrence are spatially coherent across 24 airfields and dictated by positive relationships with stability above the marine boundary layer (MBL) and MBL...

Downstream Warming and Headwater Acidity May Diminish Coldwater Habitat in Southern Appalachian Mountain Streams

Creator:: McDonnell, T. C., Sloat, M. R., Sullivan, T. J., Dolloff, C. A., Hessburg, P. F., Povak, N. A., Jackson, W. A., and Sams C.
Abstract:: Stream-dwelling species in the U.S. southern Appalachian Mountains region are particularly vulnerable to climate change and acidification. The objectives of this study were to quantify the spatial extent of contemporary suitable habitat for acid- and thermally sensitive aquatic species and to forecast future habitat loss resulting from expected temperature increases...

Spatial and Temporal Patterns of Cloud Cover and Fog Inundation in Coastal California: Ecological Implications

Creator:: Rastogi, Bharat, Williams, A. Park, Fischer, Douglas T., Iacobellis, Sam F., McEachern, Kathryn, Carvalho, Leila, Jones, Charles, Baguskas, Sara A., and Still, Christopher J.
Abstract:: The presence of low-lying stratocumulus clouds and fog has been known to modify biophysical and ecological properties in coastal California where forests are frequently shaded by low-lying clouds or immersed in fog during otherwise warm and dry summer months. Summer fog and stratus can ameliorate summer drought stress and enhance...

Giant magnetostriction in annealed Co1 − xFex thin-films

Creator:: Hunter, Dwight, Osborn, Will, Wang, Ke, Kazantseva, Nataliya, Hattrick-Simpers, Jason, Suchoski, Richard, Takahashi, Ryota, Young, Marcus L., Mehta, Apurva, Bendersky, Leonid A., Lofland, Sam E., Wuttig, Manfred, and Takeuchi, Ichiro
Abstract:: Chemical and structural heterogeneity and the resulting interaction of coexisting phases can lead to extraordinary behaviours in oxides, as observed in piezoelectric materials at morphotropic phase boundaries and relaxor ferroelectrics. However, such phenomena are rare in metallic alloys. Here we show that, by tuning the presence of structural heterogeneity in...

State of the California Current 2014-15: Impacts of the Warm-Water "Blob"

Creator:: Leising, Andrew W., Schroeder, Isaac D., Bograd, Steven J., Abell, Jeffrey, Durazo, Reginaldo, Gaxiola-Castro, Gilberto, Bjorkstedt, Eric P., Field, John, Sakuma, Keith, Robertson, Roxanne R., Goericke, Ralf, Peterson, William T., Brodeur, Ric, Barceló, Caren, Auth, Toby D., Daly, Elizabeth A., Suryan, Robert M., Gladics, Amanda J., Porquez, Jessica M., McClatchie, Sam, Weber, Edward D., Watson, William, Santora, Jarrod A., Sydeman, William J., Melin, Sharon R., Chavez, Francisco P., Golightly, Richard T., Schneider, Stephanie R., Fisher, Jennifer, Morgan, Cheryl, Bradley, Russell, and Warybok, Peter
Abstract:: In 2014, the California Current (~28˚–48˚N) saw average, or below average, coastal upwelling and relatively low productivity in most locations, except from 38˚–43˚N during June and July. Chlorophyll-a levels were low throughout spring and summer at most locations, except in a small region around 39˚N. Catches of juvenile rockfish (an...

Complete genome sequence of Nitrosomonas sp. Is79, an ammonia oxidizing bacterium adapted to low ammonium concentrations

Creator:: Bollmann, Annette, Sedlacek, Christopher J., Norton, Jeanette, Laanbroek, Hendrikus J., Suwa, Yuichi, Stein, Lisa Y., Klotz, Martin G., Arp, Daniel J., Sayavedra-Soto, Luis, Lu, Megan, Bruce, David, Detter, Chris, Tapia, Roxanne, Han, James, Woyke, Tanja, Pitluck, Sam, Pennacchio, Len, Nolan, Matt, Land, Miriam L., Huntemann, Marcel, Deshpande, Shweta, Han, Cliff, Chen, Amy, Kyrpides, Nikos, Movromatis, Konstantinos, Markowitz, Victor, Szeto, Ernest, Ivonova, Natalia, Mikhailova, Natalia, Pagani, Ioanna, Pati, Amrita, Peters, Lin, Ovchinnikova, Galina, Goodwin, Lynne A., and Lucas, Susan M.
Abstract:: Nitrosomonas sp. Is79 is a chemolithoautotrophic ammonia-oxidizing bacterium that belongs to the family Nitrosomonadaceae within the phylum Proteobacteria. Ammonia oxidation is the first step of nitrification, an important process in the global nitrogen cycle ultimately resulting in the production of nitrate. Nitrosomonas sp. Is79 is an ammonia oxidizer of high...
