Finite element simulation of dispersion in the Bay of Santander

Two mathematical models are used to simulate pollution in the Bay of Santander. The first is the hydrodynamic model that provides the velocity field and height of the water. The second gives the pollutant concentration field as a resultant. Both models are formulated in two-dimensional equations. Linear triangular finite elements are used in the Galerkin procedure for spatial discretization. A finite difference scheme is used for the time integration. At each time step the calculated results of the first model are input to the second model as field data. The efficiency and accuracy of the models are tested by their application to a simple illustrative example. Finally a case study in simulation of pollution evolution in the Bay of Santander is presented

Emerging From the Shadows : the Life of Captain John (Deserontyou), Circa 1742-1811, Founder of the Bay of Quinte Mohawk Village

This thesis is a biographical examination of the life of Mohawk leader Deserontyou (Captain John) and covers the years from the 1730's up to, and briefly following, 1811. The social, economic and political position of the Mohawk people and Deserontyou's position within the Fort Hunter community prior to the Revolution are addressed first. The Revolutionary War years are then covered with emphasis placed on Deserontyou's military role, the unpleasant conditions at Lachine and the painful reality for the Mohawk people in the aftermath of Britain's defeat. The post-war settlement on the Bay of Quinte is then explored, including the difficulties that Deserontyou experienced with the land, with the British Government, and with his own people. The documents upon which this examination are based come from many primary collections including: The Draper Manuscripts, the Haldimand Papers, the Stuart Papers, Ontario Lands & Forest Survey Records, the Society for the Propagation of the Gospel in Foreign Parts, Episcopal Records, the Bell Papers, the File Collection, the Claus Papers and Indian Affairs Papers.

Paleotemperatures and paleosalinities from the Celtic Margin (Bay of Biscay)

During the late Quaternary, both external and internal forcings have driven major climatic shifts from glacial to interglacial conditions. Nonlinear climatic steps characterized the transitions leading to these extrema, with intermediate excursions particularly well xpressed in the dynamics of the Northern Hemisphere cryosphere. Here we document the impact of these dynamics on the north-eastern North Atlantic Ocean, focussing on the 35-10 ka interval. Sea-surface salinities have been reconstructed quantitatively based on two independent methods from core MD95-2002, recovered from the northern Bay of Biscay adjacent to the axis of the Manche paleoriver outlet and thus in connection with proximal European ice sheets and glaciers. Quantitative reconstructions deriving from dinocyst and planktonic foraminiferal analyses have been combined within a robust chronology to assess the amplitude and timing of hydrological changes in this region. Our study evidences strong pulsed freshwater discharges which may have impacted the North Atlantic Meridional Overturning Circulation.
