    • Global oceanic emission of ammonia : constraints from seawater and atmospheric observations 

      Paulot, Fabien; Jacob, Daniel J.; Johnson, Martin T.; Bell, Tom G.; Baker, Alexander R.; Keene, William C.; Lima, Ivan D.; Doney, Scott C.; Stock, Charles A. (John Wiley & Sons, 2015-08-13)
      Current global inventories of ammonia emissions identify the ocean as the largest natural source. This source depends on seawater pH, temperature, and the concentration of total seawater ammonia (NHx(sw)), which reflects ...

      Schanze, Julian J.; Schmitt, Raymond W.; Yu, Lisan (Sears Foundation for Marine Research, 2010-05-01)
      The current capabilities of quantifying the oceanic freshwater cycle are shown based on new observations from satellite data and re-analysis models for evaporation and precipitation over the ocean. For this purpose, we ...
    • Global patterns of diapycnal mixing from measurements of the turbulent dissipation rate 

      Waterhouse, Amy F.; MacKinnon, Jennifer A.; Nash, Jonathan D.; Alford, Matthew H.; Kunze, Eric; Simmons, Harper L.; Polzin, Kurt L.; St. Laurent, Louis C.; Sun, Oliver M. T.; Pinkel, Robert; Talley, Lynne D.; Whalen, Caitlin B.; Huussen, Tycho N.; Carter, Glenn S.; Fer, Ilker; Waterman, Stephanie N.; Naveira Garabato, Alberto C.; Sanford, Thomas B.; Lee, Craig M. (American Meteorological Society, 2014-07)
      The authors present inferences of diapycnal diffusivity from a compilation of over 5200 microstructure profiles. As microstructure observations are sparse, these are supplemented with indirect measurements of mixing obtained ...
    • A global relationship between the ocean water cycle and near-surface salinity 

      Yu, Lisan (American Geophysical Union, 2011-10-18)
      Ocean evaporation (E) and precipitation (P) are the fundamental components of the global water cycle. They are also the freshwater flux forcing (i.e., E-P) for the open ocean salinity. The apparent connection between ocean ...
    • The global subduction/obduction rates : their interannual and decadal variability 

      Liu, Ling Ling; Huang, Rui Xin (American Meteorological Society, 2012-02-15)
      Ventilation, including subduction and obduction, for the global oceans was examined using Simple Ocean Data Assimilation (SODA) outputs. The global subduction rate averaged over the period from 1959 to 2006 is estimated ...
    • Global temperature calibration of the alkenone unsaturation index (UK′37) in surface waters and comparison with surface sediments 

      Conte, Maureen H.; Sicre, Marie-Alexandrine; Ruhlemann, Carsten; Weber, John C.; Schulte, Sonja; Schulz-Bull, Detlef; Blanz, Thomas (American Geophysical Union, 2006-02-07)
      In this paper, we compile the current surface seawater C37 alkenone unsaturation (UK′37) measurements (n=629, −1 to 30°C temperature range) to derive a global, field-based calibration of UK′37 with alkenone production ...
    • Global transcriptional profiling of the toxic dinoflagellate Alexandrium fundyense using Massively Parallel Signature Sequencing 

      Erdner, Deana L.; Anderson, Donald M. (BioMed Central, 2006-04-25)
      Dinoflagellates are one of the most important classes of marine and freshwater algae, notable both for their functional diversity and ecological significance. They occur naturally as free-living cells, as endosymbionts ...
    • Global variations in oceanic evaporation (1958–2005) : the role of the changing wind speed 

      Yu, Lisan (American Meteorological Society, 2007-11-01)
      Global estimates of oceanic evaporation (Evp) from 1958 to 2005 have been recently developed by the Objectively Analyzed Air–Sea Fluxes (OAFlux) project at the Woods Hole Oceanographic Institution (WHOI). The nearly 50-yr ...
    • Global viewport to deep-sea vents : dataset for spherical display systems 

      Beaulieu, Stace E.; Brickley, Annette; Spargo, Abbey; Joyce, Katherine; Silva, Tim; Patterson, Kathleen; Madin, Katherine; Emery, Meredith (2014-09-11)
      Spherical display systems, including digital globes, are new technologies increasingly used in both informal and formal education to display global datasets. By creating a narrative using multiple datasets, inter‐disciplinary ...
    • The global, complex phenomena of harmful algal blooms 

      Glibert, Patricia M.; Anderson, Donald M.; Gentien, Patrick; Graneli, Edna; Sellner, Kevin G. (Oceanography Society, 2005-06)
      Marine and fresh waters team with life, much of it microscopic, and most of it harmless; in fact, it is this microscopic life on which all aquatic life ultimately depends for food. Microscopic algae also play an ...
