Managing deepsea oil spills through a systematic modeling approach

Author(s): Chen Z; Yang Z; Lee K; Lu Y;

Offshore oil exploration and production in deepwater are associated with environmental risks to marine ecosystems. This research introduces DWOSM (Deep Water Oil Spill Model), a three-dimensional Lagrangian model, which is developed to simulate the transport and fate of oil spills resulting from subsea blowouts. DWOSM comprises three interconnected module ...

Insomnia symptoms among older adults during the first year of the COVID-19 pandemic: A longitudinal study

Author(s): Gong K; Garneau J; Grenier S; Vasiliadis HM; Dang-Vu TT; Dialahy IZ; Gouin JP;

Objective: To identify sociodemographic, psychological, and health factors related to trajectories of insomnia symptoms in older adults during the COVID-19 pandemic. Methods: From May 2020 to May 2021, 644 older adults (mean age = 78.73, SD = 5.60) completed telephone-administered self-reported measures (ie, Insomnia Severity Index, consensus sleep diari ...

Development and testing of a 2D offshore oil spill modeling tool (OSMT) supported by an effective calibration method

Author(s): Yang Z; Chen Z; Lee K;

An Oil Spill Modeling Tool (OSMT) has been developed in this study to predict the transport and fate of oil spills resulting from surface releases. Particularly, the Kullback-Leibler (KL) divergence method is adopted as a performance metric for the first time to formulate a calibration framework for spill trajectory prediction (STP) from the Lagrangian tr ...
