      A two-dimensional (cross-shelf) numerical model of the mean seasonal circulation offshore of southern New England predicts upwelling at the shelfbreak front. Expected ramifications of this upwelling include enhancement of ...
    • Is global ocean sprawl a cause of jellyfish blooms? 

      Duarte, Carlos M.; Pitt, Kylie A.; Lucas, Cathy H.; Purcell, Jennifer E.; Uye, Shin-Ichi; Robinson, Kelly L.; Brotz, Lucas; Decker, Mary Beth; Sutherland, Kelly R.; Malej, Alenka; Madin, Laurence P.; Mianzan, Hermes; Gili, Josep-Maria; Fuentes, Veronica; Atienza, Dacha; Pages, Francesc; Breitburg, Denise L.; Malek, Jennafer; Graham, William M.; Condon, Robert H. (Ecological Society of America, 2012-09-07)
      Jellyfish (Cnidaria, Scyphozoa) blooms appear to be increasing in both intensity and frequency in many coastal areas worldwide, due to multiple hypothesized anthropogenic stressors. Here, we propose that the proliferation ...
    • Is it the global net? 

      Avery, Beth; Pretorius, Martha (IAMSLIC, 2002)
    • Is science as global as we think? 

      Wong, Bob B. M.; Kokko, Hanna (2005)
      A cornerstone of scientific practice is the perceived freedom with which knowledge is disseminated. But does the scientific community make good use of all that is available? Researchers have, on occasion, been accused of ...
    • Is the Faroe Bank Channel overflow hydraulically controlled? 

      Girton, James B.; Pratt, Lawrence J.; Sutherland, David A.; Price, James F. (American Meteorological Society, 2006-12)
      The overflow of dense water from the Nordic Seas through the Faroe Bank Channel (FBC) has attributes suggesting hydraulic control—primarily an asymmetry across the sill reminiscent of flow over a dam. However, this aspect ...
    • Is the northern high-latitude land-based CO2 sink weakening? 

      Hayes, Daniel J.; McGuire, A. David; Kicklighter, David W.; Gurney, Kevin R.; Burnside, T. J.; Melillo, Jerry M. (American Geophysical Union, 2011-08-30)
      Studies indicate that, historically, terrestrial ecosystems of the northern high-latitude region may have been responsible for up to 60% of the global net land-based sink for atmospheric CO2. However, these regions have ...
    • Is there a need for a Mediterranean interest group? 

      Collins, Jean (IAMSLIC, 2002)
    • iSAM2 : incremental smoothing and mapping using the Bayes tree 

      Kaess, Michael; Johannsson, Hordur; Roberts, Richard; Ila, Viorela; Leonard, John J.; Dellaert, Frank (2011-04-06)
      We present a novel data structure, the Bayes tree, that provides an algorithmic foundation enabling a better understanding of existing graphical model inference algorithms and their connection to sparse matrix factorization ...
    • ISLANDS OF WORDS: INTEGRATING WRITING CENTERS INTO LIBRARIES 

      Caton, Amy; Baca, David (IAMSLIC, 2015)
    • Isolated communities of Epsilonproteobacteria in hydrothermal vent fluids of the Mariana Arc seamounts
