  • Decoupled sedimentary records of combustion : causes and implications 

    Hanke, Ulrich; Eglinton, Timothy I.; Braun, Ana L. L.; Reddy, Christopher M.; Wiedemeier, Daniel B.; Schmidt, Michael W. I. (John Wiley & Sons, 2016-05-30)
    Pyrogenic carbon (PyC) is a collective term for carbon-rich residues comprised of a continuum of products arising from biomass burning and fossil-fuel combustion. PyC is ubiquitous in the environment where it can be ...
  • N2 fixation in eddies of the eastern tropical South Pacific Ocean 

    Löscher, Carolin; Bourbonnais, Annie; Dekaezemacker, Julien; Charoenpong, Chawalit; Altabet, Mark; Bange, Hermann; Czeschel, Rena; Hoffmann, Chris; Schmitz, Ruth (Copernicus Publications on behalf of the European Geosciences Union, 2016-05-18)
    Mesoscale eddies play a major role in controlling ocean biogeochemistry. By impacting nutrient availability and water column ventilation, they are of critical importance for oceanic primary production. In the eastern ...
  • Ephemerality of discrete methane vents in lake sediments 

    Scandella, Benjamin; Pillsbury, Liam; Weber, Thomas; Ruppel, Carolyn D.; Hemond, Harold; Juanes, Ruben (John Wiley & Sons, 2016-05-04)
    Methane is a potent greenhouse gas whose emission from sediments in inland waters and shallow oceans may both contribute to global warming and be exacerbated by it. The fraction of methane emitted by sediments that bypasses ...
  • A compilation of global bio-optical in situ data for ocean-colour satellite applications 

    Valente, André; Sathyendranath, Shubha; Brotas, Vanda; Groom, Steven; Grant, Michael; Taberner, Malcolm; Antoine, David; arnone, robert; Balch, William; Barker, Kathryn; Barlow, Ray; Belanger, Simon; Berthon, Jean-François; Besiktepe, Sukru; Brando, Vittorio; Canuti, Elisabetta; Chavez, Francisco; Claustre, Hervé; Crout, Richard; Frouin, Robert; García-Soto, Carlos; Gibb, Stuart W.; Gould, Richard; Hooker, Stanford; Kahru, Mati; Klein, Holger; Kratzer, Susanne; loisel, hubert; McKee, David; Mitchell, Brian G.; Moisan, Tiffany; Muller-Karger, Frank; O'Dowd, Leonie; Ondrusek, Michael; Poulton, Alex J.; REPECAUD, Michel; Smyth, Timothy; Sosik, Heidi M.; Twardowski, Michael; Voss, Kenneth; Werdell, Jeremy; Wernand, Marcel; Zibordi, Giuseppe (Copernicus Publications on behalf of the European Geosciences Union, 2016-06-03)
    A compiled set of in situ data is important to evaluate the quality of ocean-colour satellite-data records. Here we describe the data compiled for the validation of the ocean-colour products from the ESA Ocean Colour Climate ...
  • Interpretation of gravity and magnetic anomalies at Lake Rotomahana: geological and hydrothermal implications 

    Tontini, F. Caratori; de Ronde, Cornel E. J.; Scott, Bradley J.; Soengkono, Supri; Stagpoole, Vaughan; Timm, Christian; Tivey, Maurice (2015-03)
    We investigate the geological and hydrothermal setting at Lake Rotomahana, using recently collected potential-field data, integrated with pre-existing regional gravity and aeromagnetic compilations. The lake is located ...
  • Phase separation of signaling molecules promotes T cell receptor signal transduction 

    Su, Xiaolei; Ditlev, Jonathon; Hui, Enfu; Xing, Wenmin; Banjade, Sudeep; Okrut, Julia; King, David S.; Taunton, Jack; Rosen, Michael K.; Vale, Ronald D. (2016-03)
    Activation of various cell surface receptors triggers the reorganization of downstream signaling molecules into micron- or submicron-sized clusters. However, the functional consequences of such clustering has been unclear. ...
  • Quantifying the impact of submesoscale processes on the spring phytoplankton bloom in a turbulent upper ocean using a Lagrangian approach 

    Brody, Sarah R.; Lozier, M Susan; Mahadevan, Amala (John Wiley & Sons, 2016-05-18)
    The spring phytoplankton bloom in the subpolar North Atlantic and the mechanisms controlling its evolution and onset have important consequences for marine ecosystems and carbon cycling. Submesoscale mixed layer eddies ...
  • On the temperature dependence of oceanic export efficiency 

    Cael, B. Barry; Follows, Michael J. (John Wiley & Sons, 2016-05-18)
    Quantifying the fraction of primary production exported from the euphotic layer (termed the export efficiency ef) is a complicated matter. Studies have suggested empirical relationships with temperature which offer attractive ...
  • Mapping turbulent diffusivity associated with oceanic internal lee waves offshore Costa Rica 

    Fortin, Will F. J.; Holbrook, W. Steven; Schmitt, Raymond W. (Copernicus Publications on behalf of the European Geosciences Union, 2016-04-26)
    Breaking internal waves play a primary role in maintaining the meridional overturning circulation. Oceanic lee waves are known to be a significant contributor to diapycnal mixing associated with internal wave dissipation, ...
  • High-resolution water column survey to identify active sublacustrine hydrothermal discharge zones within Lake Rotomahana, North Island, New Zealand 

    Walker, Sharon L.; de Ronde, Cornel E. J.; Fornari, Daniel J.; Tivey, Maurice; Stucker, Valerie (Elsevier, 2015-08-12)
    Autonomous underwater vehicles were used to conduct a high-resolution water column survey of Lake Rotomahana using temperature, pH, turbidity, and oxidation–reduction potential (ORP) to identify active hydrothermal discharge ...
