Limacina helicina shell dissolution as an indicator of declining habitat suitability owing to ocean acidification in the California Current Ecosystem

Creator:: Bednaršek, N., Feely, R. A., Reum, J. C. P., Peterson, B., Menkel, J., Alin, S. R., and Hales, B.
Abstract:: Few studies to date have demonstrated widespread biological impacts of ocean acidification (OA) under conditions currently found in the natural environment. From a combined survey of physical and chemical water properties and biological sampling along the Washington–Oregon–California coast in August 2011, we show that large portions of the shelf waters...

River Microbiome Composition Reflects Macroscale Climatic and Geomorphic Differences in Headwater Streams

Creator:: URycki, Dawn R., Good, Stephen P., Crump, Byron C., Chadwick, Jessica, and Jones, Gerrad D.
Abstract:: Maintaining the quality and quantity of water resources in light of complex changes in climate, human land use, and ecosystem composition requires detailed understanding of ecohydrologic function within catchments, yet monitoring relevant upstream characteristics can be challenging. In this study, we investigate how variability in riverine microbial communities can be...

The salinity signature of the cross-shelf exchanges in the Southwestern Atlantic Ocean: Satellite observations

Creator:: Guerrero, Raul A., Piola, Alberto R., Fenco, Harold, Matano, Ricardo P., Combes, Vincent, Chao, Yi, James, Corinne, Palma, Elbio D., Saraceno, Martin, and Strub, P. Ted
Abstract:: Satellite‐derived sea surface salinity (SSS) data from Aquarius and SMOS are used to study the shelf‐open ocean exchanges in the western South Atlantic near 35°S. Away from the tropics, these exchanges cause the largest SSS variability throughout the South Atlantic. The data reveal a well‐defined seasonal pattern of SSS during...

Biological production in the NE Pacific and its influence on air-sea CO2 flux: Evidence from dissolved oxygen isotopes and O2/Ar

Creator:: Juranek, L. W., Quay, P. D., Feely, R. A., Lockwood, D., Karl, D. M., and Church, M. J.
Abstract:: We determine rates of gross photosynthetic O₂ production (GOP) and net community O₂ production (NCP) using the triple oxygen isotope and O₂/Ar approach on two spring and two late summer meridional transects of the NE Pacific. Observed GOP and NCP in the subtropical (89 ± 9 and 8.3 ± 1.3...

Biodiversity on the Rocks : Macrofauna Inhabiting Authigenic Carbonate at Costa Rica Methane Seeps

Creator:: Levin, Lisa A., Mendoza, Guillermo F., Grupe, Benjamin M., Gonzalez, Jennifer P., Jellison, Brittany, Rouse, Greg, Thurber, Andrew R., and Waren, Anders
Abstract:: Carbonate communities:The activity of anaerobic methane oxidizing microbes facilitates precipitation of vast quantities of authigenic carbonate at methane seeps. Here we demonstrate the significant role of carbonate rocks in promoting diversity by providing unique habitat and food resources for macrofaunal assemblages at seeps on the Costa Rica margin (400–1850 m)....

Age systematics of two young en echelon Samoan volcanic trails

Creator:: Koppers, Anthony A. P., Russell, Jamie A., Roberts, Jed, Jackson, Matthew G., Konter, Jasper G., Wright, Dawn J., Staudigel, Hubert, and Hart, Stanley R.
Abstract:: The volcanic origin of the Samoan archipelago can be explained by one of three models, specifically, by a hot spot forming over a mantle plume, by lithospheric extension resulting from complex subduction tectonics in the region, or by a combination of these two processes, either acting sequentially or synchronously. In...

The WAIS Divide deep ice core WD2014 chronology – Part 1: Methane synchronization (68–31 kaBP) and the gas age–ice age difference

Creator:: Buizert, C., Cuffey, K. M., Severinghaus, J. P., Baggenstos, D., Fudge, T. J., Steig, E. J., Markle, B. R., Winstrup, M., Rhodes, R. H., Brook, Edward J., Sowers, T. A., Clow, G. D., Cheng, H., Edwards, R. L., Sigl, M., McConnell, J. R., and Taylor, K. C.
Abstract:: The West Antarctic Ice Sheet Divide (WAIS Divide, WD) ice core is a newly drilled, high-accumulation deep ice core that provides Antarctic climate records of the past ~68 ka at unprecedented temporal resolution. The upper 2850 m (back to 31.2 ka BP) have been dated using annual-layer counting. Here we...

C., Vandemark, D., Vlahos, P., Wallace, D. W. R., Wanninkhof, R., and Watson, A. J.
Abstract:: The Surface Ocean CO2 Atlas (SOCAT), an activity of the international marine carbon research community, provides access to synthesis and gridded fCO2 (fugacity of carbon dioxide) products for the surface oceans. Version 2 of SOCAT is an update of the previous release (version 1) with more data (increased from 6.3...
