Technical note: Time lag correction of aquatic eddy covariance data measured in the presence of waves

Creator:: Berg, P., Reimers, Clare E., Rosman, J. H., Huettel, M., Delgard, M. L., Reidenbach, M. A., and Özkan-Haller, H. Tuba
Abstract:: Extracting benthic oxygen fluxes from eddy covariance time series measured in the presence of surface gravity waves requires careful consideration of the temporal alignment of the vertical velocity and the oxygen concentration. Using a model based on linear wave theory and measured eddy covariance data, we show that a substantial...

The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns

Creator:: Henty-Ridilla, Jessica L., Shimono, Masaki, Li, Jiejie, Chang, Jeff H., Day, Brad, and Staiger, Christopher J.
Abstract:: Plants are constantly exposed to a large and diverse array of microbes; however, most plants are immune to the majority of potential invaders and susceptible to only a small subset of pathogens. The cytoskeleton comprises a dynamic intracellular framework that responds rapidly to biotic stresses and supports numerous fundamental cellular...

Switching Hemispheres: A New Migration Strategy for the Disjunct Argentinean Breeding Population of Barn Swallow (Hirundo rustica)

Creator:: Garcia-Perez, Belen, Hobson, Keith A., Powell, Rebecca L., Still, Christopher J., and Huber, Gernot H.
Abstract:: Background: Barn Swallows (Hirundo rustica) breed almost exclusively in the Northern Hemisphere. However, since the early 1980's, a small disjunct breeding population has become established in eastern Argentina, presumably by birds previously derived from those breeding in North America. Currently, it is unknown where these individuals go following breeding and...

Calcium carbonate production response to future ocean warming and acidification

Creator:: Pinsonneault, A. J., Matthews, H. D., Galbraith, E. D., and Schmittner, A.
Abstract:: Anthropogenic carbon dioxide (CO₂) emissions are acidifying the ocean, affecting calcification rates in pelagic organisms, and thereby modifying the oceanic carbon and alkalinity cycles. However, the responses of pelagic calcifying organisms to acidification vary widely between species, contributing uncertainty to predictions of atmospheric CO₂ and the resulting climate change. At...

High resolution measurements of carbon monoxide along a late Holocene Greenland ice core: evidence for in situ production

Creator:: Faïn, X., Chappellaz, J., Rhodes, R. H., Stowasser, C., Blunier, T., McConnell, J. R., Brook, E. J., Preunkert, S., Legrand, M., Debois, T., and Romanini, D.
Abstract:: We present high-resolution measurements of carbon monoxide (CO) concentrations from a shallow ice core of the North Greenland Eemian Ice Drilling project (NEEM-2011-S1). An optical-feedback cavity-enhanced absorption spectrometer (OF-CEAS) coupled to a continuous melter system performed continuous, online analysis during a four-week measurement campaign. This analytical setup generated stable measurements...

Seasonal methane accumulation and release from a gas emission site in the central North Sea

Creator:: Mau, S., Gentz, T., Körber, J.-H., Torres, M. E., Römer, M., Sahling, H., Wintersteller, P., Martinez, R., Schlüter, M., and Helmke, E.
Abstract:: Hydroacoustic data document the occurrence of 5 flare clusters and several single flares from which bubbles rise through the entire water column from an active seep site at 40 m water depth in the central North Sea. We investigated the difference in dissolved methane distributions along a 6 km transect...

Seasonal methane accumulation and release from a gas emission site in the central North Sea

Creator:: Mau, S., Gentz, T., Körber, J.-H., Torres, M. E., Römer, M., Sahling, H., Wintersteller, P., Martinez, R., Schlüter, M., and Helmke, E.
Abstract:: We investigated dissolved methane distributions along a 6 km transect crossing active seep sites at 40 m water depth in the central North Sea. These investigations were done under conditions of thermal stratification in summer (July 2013) and homogenous water column in winter (January 2014). Dissolved methane accumulated below the...

Where to find 1.5 million yr old ice for the IPICS “Oldest-Ice” ice core

Creator:: Fischer, H., Severinghaus, J., Brook, Edward J., Wolff, E., Albert, M., Alemany, O., Arthern, R., Bentley, C., Blankenship, D., Chappellaz, J., Creyts, T., Dahl-Jensen, D., Dinn, M., Frezzotti, M., Fujita, S., Gallee, H., Hindmarsh, R., Hudspeth, D., Jugie, G., Kawamura, K., Lipenkov, V., Miller, H., Mulvaney, R., Parrenin, F., Pattyn, F., Ritz, C., Schwander, J., Steinhage, D., van Ommen, T., and Wilhelms, F.
Abstract:: The recovery of a 1.5 million yr long ice core from Antarctica represents a keystone of our understanding of Quaternary climate, the progression of glaciation over this time period and the role of greenhouse gas cycles in this progression. Here we tackle the question of where such ice may still...

Local artifacts in ice core methane records caused by layered bubble trapping and in situ production: a multi-site investigation

Creator:: Rhodes, Rachael H., Faïn, Xavier, Brook, Edward J., McConnell, Joseph R., Maselli, Olivia J., Sigl, Michael, Edwards, Jon, Buizert, Christo, Blunier, Thomas, Chappellaz, Jérôme, and Freitag, Johannes
Abstract:: Advances in trace gas analysis allow localised, non-atmospheric features to be resolved in ice cores, superimposed on the coherent atmospheric signal. These high-frequency signals could not have survived the low-pass filter effect that gas diffusion in the firn exerts on the atmospheric history and therefore do not result from changes...
