Metabolic balance of coastal Antarctic waters revealed by autonomous pCO₂ and ΔO₂/Ar measurements

Creator:: Tortell, Philippe D., Asher, Elizabeth C., Ducklow, Hugh W., Goldman, Johanna A. L., Dacey, John W. H., Grzymski, Joseph J., Young, Jodi N., Kranz, Sven A., Bernard, Kim S., and Morel, François M. M.
Abstract:: We use autonomous gas measurements to examine the metabolic balance (photosynthesis minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations capture the development of a massive phytoplankton bloom and reveal striking variability in pCO₂ and biological oxygen saturation (ΔO₂/Ar) resulting from large shifts in community metabolism...

Deeply dredged submarine HIMU glasses from the Tuvalu Islands, Polynesia: Implications for volatile budgets of recycled oceanic crust

Creator:: Jackson, M. G., Koga, K. T., Price, A., Koppers, A. A. P., Finlayson, V. A., Konrad, K., Hauri, E. H., Kylander-Clark, A., Kelley, K. A., and Kendrick, M. A.
Abstract:: Ocean island basalts (OIB) with extremely radiogenic Pb-isotopic signatures are melts of a mantle component called HIMU (high µ, high ²³⁸U/²⁰⁴Pb). Until now, deeply dredged submarine HIMU glasses have not been available, which has inhibited complete geochemical (in particular, volatile element) characterization of the HIMU mantle. We report major, trace...

Geochemical evidence in the northeast Lau Basin for subduction of the Cook-Austral volcanic chain in the Tonga Trench

Creator:: Price, Allison A., Jackson, Matthew G., Blichert-Toft, Janne, Blusztajn, Jerzy, Conatser, Christopher S., Konter, Jasper G., Koppers, Anthony A. P., and Kurz, Mark D.
Abstract:: Lau Basin basalts host an array of geochemical signatures that suggest incorporation of enriched mantle source material often associated with intraplate hotspots, but the origin of these signatures remain uncertain. Geochemical signatures associated with mantle material entrained from the nearby Samoan hotspot are present in northwest Lau Basin lavas, and...

Influence of varying upper ocean stratification on coastal near-inertial currents

Creator:: Kim, Sung Yong, Kurapov, Alexander L., and Kosro, P. Michael
Abstract:: The influence of varying horizontal and vertical stratification in the upper layer ( inline image m) associated with riverine waters and seasonal atmospheric fluxes on coastal near-inertial currents is investigated with remotely sensed and in situ observations of surface and subsurface currents and realistic numerical model outputs off the coast...

Southern Ocean control of glacial AMOC stability and Dansgaard-Oeschger interstadial duration

Creator:: Buizert, Christo and Schmittner, Andreas
Abstract:: Glacial periods exhibit abrupt Dansgaard-Oeschger (DO) climatic oscillations that are thought to be linked to instabilities in the Atlantic meridional overturning circulation (AMOC). Great uncertainty remains regarding the dynamics of the DO cycle, as well as controls on the timing and duration of individual events. Using ice core data we...

A multiscale climate emulator for long-term morphodynamics (MUSCLE-morpho)

Creator:: Antolínez, José Antonio A., Méndez, Fernando J., Camus, Paula, Vitousek, Sean, González, E. Mauricio, Ruggiero, Peter, and Barnard, Patrick
Abstract:: Interest in understanding long-term coastal morphodynamics has recently increased as climate change impacts become perceptible and accelerated. Multiscale, behavior-oriented and process-based models, or hybrids of the two, are typically applied with deterministic approaches which require considerable computational effort. In order to reduce the computational cost of modeling large spatial and...

Precipitation and winter temperature predict long-term range-scale abundance changes in Western North American birds

Creator:: Illán, Javier Gutiérrez, Thomas, Chris D., Jones, Julia A., Wong, Weng-Keen, Shirley, Susan M., and Betts, Matthew G.
Abstract:: Predicting biodiversity responses to climate change remains a difficult challenge, especially in climatically complex regions where precipitation is a limiting factor. Though statistical climatic envelope models are frequently used to project future scenarios for species distributions under climate change, these models are rarely tested using empirical data. We used long-term...

Does wildfire likelihood increase following insect outbreaks in conifer forests?

Creator:: Meigs, Garrett W., Campbell, John L., Zald, Harold S. J., Bailey, John D., Shaw, David C., and Kennedy, Robert E.
Abstract:: Although there is acute concern that insect-caused tree mortality increases the likelihood or severity of subsequent wildfire, previous studies have been mixed, with findings typically based on stand-scale simulations or individual events. This study investigates landscape- and regional-scale wildfire likelihood following outbreaks of the two most prevalent native insect pests...
