  • CO2 deposition over the multi-year ice of the western Weddell Sea 

    Zemmelink, Hendrik J.; Delille, B.; Tison, J. L.; Hintsa, Eric J.; Houghton, Leah; Dacey, John W. H. (American Geophysical Union, 2006-07-13)
    Field measurements by eddy correlation (EC) indicate an average uptake of 0.6 g CO2 m−2 d−1 by the ice-covered western Weddell Sea in December 2004. At the same time, snow that covers ice floes of the western Weddell Sea ...
  • Dimethylsulfide emissions over the multi-year ice of the western Weddell Sea 

    Zemmelink, Hendrik J.; Dacey, John W. H.; Houghton, Leah; Hintsa, Eric J.; Liss, P. S. (American Geophysical Union, 2008-03-20)
    This study, conducted in December 2004, is the first to present observations of DMS in a snow pack covering the multi-year sea ice of the western Weddell Sea. The snow layer is important because it is the interface through ...
  • Direct measurements of biogenic dimethylsulphide fluxes from the oceans : a synthesis 

    Zemmelink, Hendrik J.; Dacey, John W. H.; Hintsa, Eric J. (National Research Council Canada, 2004-06-24)
    This paper provides a brief overview of the state-of-the-art of techniques that are currently used for field measurements of trace gas fluxes and the subsequent derivation of gas transfer rates over the oceans. Special ...
  • Emission of dimethylsulfide from Weddell Sea leads 

    Zemmelink, Hendrik J.; Houghton, Leah; Dacey, John W. H.; Worby, A. P.; Liss, P. S. (American Geophysical Union, 2005-12-10)
    The distribution of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP) and dimethylsulfoxide (DMSO) was examined in lead water in pack ice of the Weddell Sea. Samples were taken by pulling water into a syringe from ...
  • Environmental turbulent mixing controls on air-water gas exchange in marine and aquatic systems 

    Zappa, Christopher J.; McGillis, Wade R.; Raymond, Peter A.; Edson, James B.; Hintsa, Eric J.; Zemmelink, Hendrik J.; Dacey, John W. H.; Ho, David T. (American Geophysical Union, 2007-05-17)
    Air-water gas transfer influences CO2 and other climatically important trace gas fluxes on regional and global scales, yet the magnitude of the transfer is not well known. Widely used models of gas exchange rates are based ...
  • Fluxes and gas transfer rates of the biogenic trace gas DMS derived from atmospheric gradients 

    Zemmelink, Hendrik J.; Dacey, John W. H.; Hintsa, Eric J.; McGillis, Wade R.; Gieskes, Winfried W. C.; Klaassen, Wim; de Groot, Henk W.; Baar, Hein J. W. de (American Geophysical Union, 2004-06-30)
    Gas transfer rates were determined from vertical profile measurements of atmospheric dimethylsulfide (DMS) gradients over the equatorial Pacific Ocean obtained during the GasEx-2001 cruise. A quadratic relationship between ...
  • Gradients in dimethylsulfide, dimethylsulfoniopropionate, dimethylsulfoxide, and bacteria near the sea surface 

    Zemmelink, Hendrik J.; Houghton, Leah; Sievert, Stefan M.; Frew, Nelson M.; Dacey, John W. H. (Inter-Research, 2005-06-23)
    Gradients of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP), dimethylsulfoxide (DMSO), and bacterial numbers and diversity from the surface microlayer to 500 cm depth were assessed in coastal waters surrounding ...
  • Physical exchanges at the air–sea interface : UK–SOLAS field measurements 

    Brooks, Ian M.; Bloom, A. Anthony; Brooks, Barbara J.; Lingard, Justin J. N.; McQuaid, James B.; Norris, Sarah J.; Smith, Michael H.; Smith, Paul D.; Yelland, Margaret J.; Moat, Ben I.; Pascal, Robin W.; Prytherch, John; Srokosz, Meric; Taylor, Peter K.; Upstill-Goddard, Robert C.; Salter, Matt; Nightingale, Philip D.; Archer, Stephen D.; Beale, Rachael; Dixon, Jo; Goldson, Laura E.; Hardman-Mountford, Nick; Liddicoat, Malcolm; Moore, Gerald; Stephens, John A.; D'Asaro, Eric A.; McNeil, Craig L.; Beatty, Cory; DeGrandpre, Michael D.; Blomquist, Byron; Huebert, Barry; Cluderay, John; Zemmelink, Hendrik J.; Coles, David; Hsueh, Ping-Chang; Leighton, Timothy G.; Dacey, John W. H.; Drennan, William M.; Rebozo, Mike; Sahlee, Erik; Gabriele, Joseph; Hill, Martin K.; Horn, Matt; De Leeuw, Gerrit; Neill, Craig; Skjelvan, Ingunn; O'Doherty, Simon; Walsh, Roisin; Young, Dickon; Schuster, Ute; Telszewski, Maciej; Slagter, Hans; Ward, Brian; Woolf, David K. (American Meteorological Society, 2009-05)
    As part of the U.K. contribution to the international Surface Ocean–Lower Atmosphere Study, a series of three related projects—DOGEE, SEASAW, and HiWASE—undertook experimental studies of the processes controlling the ...
  • Relaxed eddy accumulation measurements of the sea-to-air transfer of dimethylsulfide over the northeastern Pacific 

    Zemmelink, Hendrik J.; Gieskes, Winfried W. C.; Klaassen, Wim; Beukema, Wim J.; de Groot, Henk W.; Baar, Hein J. W. de; Hintsa, Eric J.; McGillis, Wade R.; Dacey, John W. H. (American Geophysical Union, 2004-01-30)
    Gas transfer rates were determined from relaxed eddy accumulation (REA) measurements of the flux of dimethylsulfide (DMS) over the northeastern Pacific Ocean. This first application of the REA technique for the measurement ...
  • Sea-to-air fluxes from measurements of the atmospheric gradient of dimethylsulfide and comparison with simultaneous relaxed eddy accumulation measurements 

    Hintsa, Eric J.; Dacey, John W. H.; McGillis, Wade R.; Edson, James B.; Zappa, Christopher J.; Zemmelink, Hendrik J. (American Geophysical Union, 2004-01-30)
    We measured vertical profiles of dimethylsulfide (DMS) in the atmospheric marine boundary layer from R/P FLIP during the 2000 FAIRS cruise. Applying Monin-Obukhov similarity theory to the DMS gradients and simultaneous ...
