    • A large-scale methane model by incorporating the surface water transport 

      Lu, Xiaoliang; Zhuang, Qianlai; Liu, Yaling; Zhou, Yuyu; AghaKouchak, Amir (John Wiley & Sons, 2016-06-28)
      The effect of surface water movement on methane emissions is not explicitly considered in most of the current methane models. In this study, a surface water routing was coupled into our previously developed large-scale ...
    • Large-scale responses of complex-shaped coastlines to local shoreline stabilization and climate change 

      Slott, Jordan M.; Murray, A. Brad; Ashton, Andrew D. (American Geophysical Union, 2010-09-16)
      When modeling the large-scale (> km) evolution of coastline morphology, the influence of natural forces is not the only consideration; ongoing direct human manipulations can substantially drive geomorphic change. In this ...
    • Large-scale, realistic laboratory modeling of M2 internal tide generation at the Luzon Strait 

      Mercier, Matthieu J.; Gostiaux, Louis; Helfrich, Karl R.; Sommeria, Joel; Viboud, Samuel; Didelle, Henri; Ghaemsaidi, Sasan J.; Dauxois, Thierry; Peacock, Thomas (John Wiley & Sons, 2013-11-04)
      The complex double-ridge system in the Luzon Strait in the South China Sea (SCS) is one of the strongest sources of internal tides in the oceans, associated with which are some of the largest amplitude internal solitary ...
    • A large-volume, deep-sea submersible pumping system 

      Sachs, Peter L.; Hammar, Terence R.; Bacon, Michael P. (Woods Hole Oceanographic Institution, 1989-11)
      Eight self-contained, in-situ pumps have been used effectively and routinely by our group for the past six years to collect both particulate and dissolved phases from large volumes of sea water. Multiple pumps are rapidly ...
    • Larvae from afar colonize deep-sea hydrothermal vents after a catastrophic eruption 

      Mullineaux, Lauren S.; Adams, Diane K.; Mills, Susan W.; Beaulieu, Stace E. (2010-01-29)
      The planktonic larval stage is a critical component of life history in marine benthic species because it confers the ability to disperse, potentially connecting remote populations and leading to colonization of new sites. ...
    • Larval dispersal : vent life in the water column 

      Adams, Diane K.; Arellano, Shawn M.; Govenar, Breea (The Oceanography Society, 2012-03)
      Visually striking faunal communities of high abundance and biomass cluster around hydrothermal vents, but these animals don't spend all of their lives on the seafloor. Instead, they spend a portion of their lives as tiny ...
    • Larval dispersal between hydrothermal vent habitats 

      Kim, Stacy L. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1996-01)
      Hydrothermal vents are isolated, short-term habitats that support unique biotic assemblages with relatively high biomass utilizing an unusual energy source. How these communities establish themselves and maintain species ...
    • Larval dispersion along an axially symmetric mid-ocean ridge 

      McGillicuddy, Dennis J.; Lavelle, J. William; Thurnherr, Andreas M.; Kosnyrev, V. K.; Mullineaux, Lauren S. (2009-12-22)
      We investigated planktonic larval transport processes along an axially symmetric mid-ocean ridge with characteristics similar to that of the East Pacific Rise (EPR) segment at 9-10°N. The hydrodynamic basis for this study ...
    • Larval ecology and synchronous reproduction of two crustacean species : Semibalanus balanoides in New England, USA and Gecarcinus quadratus in Veraguas, Panama 

      Gyory, Joanna (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2011-02)
      The environmental cues for synchronous reproduction were investigated for two highly abundant, ecologically important crustacean species: the temperate acorn barnacle, Semibalanus balanoides, and the tropical terrestrial ...
    • Larval responses to turbulence and temperature in a tidal inlet: Habitat selection by dispersing gastropods? 

      Fuchs, Heidi L.; Solow, Andrew R.; Mullineaux, Lauren S. (Sears Foundation for Marine Research, 2010-06)
      Marine larval dispersal is affected by hydrodynamic transport and larval behavior, but little is known about how behavior affects large-scale patterns of dispersal and recruitment. Intertidal habitats are characterized by ...
    • Larval settlement in flocculated particulates 

      Zimmer, Cheryl Ann; Starczak, Victoria R.; Arch, Victoria S.; Zimmer, Richard K. (Sears Foundation for Marine Research, 2008-03)
      Planktonic larval settlement can be a major determinant of population and community dynamics. Settlement templates of benthic invertebrates have been attributed to biological, chemical, and hydrodynamic mechanisms. Completely ...
    • Larval transport and dispersal in the coastal ocean and consequences for population connectivity 

      Pineda, Jesus; Hare, Jonathan A.; Sponaungle, Su (Oceanography Society, 2007-09)
      Many marine species have small, pelagic early life stages. For those species, knowledge of population connectivity requires understanding the origin and trajectories of dispersing eggs and larvae among subpopulations. ...
    • Laser (U-Th)/He thermochronology of detrital zircons as a tool for studying surface processes in modern catchments 

      Tripathy-Lang, Alka; Hodges, Kip V.; Monteleone, Brian D.; van Soest, Matthijs C. (John Wiley & Sons, 2013-07-26)
      Detrital mineral thermochronology of modern sediments is a valuable tool for interrogating landscape evolution. Detrital zircon (U-Th)/He thermochronology is of particular interest because zircons are durable and withstand ...
    • Laser diffraction particle sizing : sampling and inversion 

      Riley, James B. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1987-08-13)
      The inverse problem of obtaining particle size distributions from observations of the angular distribution of near forward scattered light is reexamined. Asymptotic analysis of the forward problem reveals the ...
    • Laser induced breakdown spectroscopy for heavy metal detection in a sand matrix 

      Michel, Anna P. M.; Sonnichsen, Frederick (2016-09-21)
      Sediments in many locations, including harbors and coastal areas, can become contaminated and polluted, for example, from anthropogenic inputs, shipping, human activities, and poor waste management. Sampling followed by ...

      Magidson, Valentin; Loncarek, Jadranka; Hergert, Polla; Rieder, Conly L.; Khodjakov, Alexey (2007-06)
      Modern biology is based largely on a reductionistic ‘dissection’ approach – most cell biologists try to determine how complex biological systems work by removing their individual parts and studying the effects of this ...
