  • Accounting for marine economic activities in large marine ecosystems 

    Hoagland, Porter; Jin, Di (2007-09)
    We develop an index that is a measure of the intensity of marine activities in large marine ecosystems (LMEs). We compare this marine activity index with an index of socioeconomic development across ocean regions. This ...

  • An analysis of fishing vessel accidents in fishing areas off the northeastern United States 

    Jin, Di; Thunberg, Eric M. (2005-02-17)

  • Anthropogenic nutrients and harmful algae in coastal waters 

    Davidson, Keith; Gowen, Richard J.; Harrison, Paul J.; Fleming, Lora E.; Hoagland, Porter; Moschonas, Grigorios (Elsevier, 2014-08-28)
    Harmful algal blooms (HABs) are thought to be increasing in coastal waters worldwide. Anthropogenic nutrient enrichment has been proposed as a principal causative factor of this increase through elevated inorganic and/or ...
  • Aquaculture and capture fisheries : a conceptual approach toward an integrated economic-ecological analysis 

    Jin, Di (2012-08-02)
    This study presents a framework for analyzing the interactions between aquaculture and capture fisheries in the context of ecosystem-based management. We extend a model of the economic and ecological systems in coastal ...
  • Are marine protected areas a red herring or fisheries panacea? 

    Kaiser, Michel J. (National Research Council Canada, 2005-05-31)
    Chronic failures in marine fisheries management have led some to suggest that marine protected areas (MPAs) are the solution to achieve sustainable fisheries. While such systems work for certain habitat-specific and nonmobile ...
  • Are there eco-metrics for fisheries? 

    Steele, John H. (2005-11-03)
    Ecosystem based management of marine resources is a worthy ideal. At present, however, the science is unable to measure and relate the fundamental concepts of diversity, productivity and resilience required for management ...
  • Assessment of management to mitigate anthropogenic effects on large whales 

    van der Hoop, Julie M.; Moore, Michael J.; Barco, Susan G.; Cole, Timothy V. N.; Daoust, Pierre-Yves; Henry, Allison G.; McAlpine, Donald F.; McLellan, William A.; Wimmer, Tonya; Solow, Andrew R. (John Wiley & Sons, 2012-10-01)
    United States and Canadian governments have responded to legal requirements to reduce human-induced whale mortality via vessel strikes and entanglement in fishing gear by implementing a suite of regulatory actions. We ...
  • Balancing end-to-end budgets of the Georges Bank ecosystem 

    Steele, John H.; Collie, Jeremy S.; Bisagni, James J.; Gifford, Dian J.; Fogarty, Michael J.; Link, Jason S.; Sullivan, B. K.; Sieracki, Michael E.; Beet, Andrew R.; Mountain, David G.; Durbin, Edward G.; Palka, D.; Stockhausen, W. T. (2007-05-09)
    Oceanographic regimes on the continental shelf display a great range in the time scales of physical exchange, biochemical processes and trophic transfers. The close surface-to-seabed physical coupling at intermediate scales ...
  • A broad-scale profile of the marine advanced technology industry 

    Kite-Powell, Hauke L. (Woods Hole Oceanographic Institution, 1988-03)
    Within the maritime sector of the United States economy, in which many industries are largely moribund (shipbuilding), flagging (international shipping), or often in disarray (fisheries), electronic marine instrumentation ...
  • The challenge to detect and attribute effects of climate change on human and natural systems 

    Stone, Daithi; Auffhammer, Maximilian; Carey, Mark; Hansen, Gerrit; Huggel, Christian; Cramer, Wolfgang; Lobell, David; Molau, Ulf; Solow, Andrew R.; Tibig, Lourdes; Yohe, Gary (Springer, 2013-08-30)
    Anthropogenic climate change has triggered impacts on natural and human systems world-wide, yet the formal scientific method of detection and attribution has been only insufficiently described. Detection and attribution ...
  • Changes in work habits of lifeguards in relation to Florida red tide 

    Nierenberg, Kate; Kirner, Karen; Hoagland, Porter; Ullmann, Steven G.; LeBlanc, William G.; Kirkpatrick, Gary; Fleming, Lora E.; Kirkpatrick, Barbara (2010-06-15)
    The marine dinoflagellate, Karenia brevis, is responsible for Florida red tides. Brevetoxins, the neurotoxins produced by K. brevis blooms, can cause fish kills, contaminate shellfish, and lead to respiratory illness in ...
  • Characterizing the error in the estimated age-depth relationship 

    Solow, Andrew R. (Dept. of Geosciences, University of Arizona, 2003)
    It is common practice to estimate the age of undated material extracted from a sediment core from radiocarbon or other radiometric dates of samples taken above and below the extracted material. This paper presents a simple ...
  • Climate-driven sea level anomalies modulate coastal groundwater dynamics and discharge 

    Gonneea, Meagan E.; Mulligan, Ann E.; Charette, Matthew A. (John Wiley & Sons, 2013-06-03)
    To better understand the physical drivers of submarine groundwater discharge (SGD) in the coastal ocean, we conducted a detailed field and modeling study within an unconfined coastal aquifer system. We monitored the hydraulic ...
  • Comparing multistate expected damages, option price and cumulative prospect measures for valuing flood protection 

    Farrow, Scott; Scott, Michael (John Wiley & Sons, 2013-05-28)

  • Comparing species and ecosystem-based estimates of fisheries yields 

    Steele, John H.; Gifford, Dian J.; Collie, Jeremy S. (2011-06)
