Water Quality Dynamics Of Lake James In The Catawba River Basin Of North Carolina, Susan Stokes Dec 2007

Water Quality Dynamics Of Lake James In The Catawba River Basin Of North Carolina, Susan Stokes

All Dissertations

Lake James is the uppermost hydropower reservoir in the Catawba River drainage in North Carolina. The Lake James Assessment (LJA) was a descriptive study initiated between Clemson University and Duke Energy Corporation to explore the physical, chemical and biological dynamics of this oligotrophic reservoir from spring 1997 through fall 1999 (Schindler 1997). The goals of this study were to ascertain the primary drivers for the chemical dynamics of Lake James, to assess the quantities of constituents entering and leaving the reservoir, where these chemicals were incorporated within the reservoir basins, and to evaluate the efficacy of the LJA chemical budget …


Mesosphere And Lower Thermosphere Neutral Winds Observations Using Rocket-Released Chemical Trails At Poker Flat, Alaska, Tianyu Zhan Aug 2007

Mesosphere And Lower Thermosphere Neutral Winds Observations Using Rocket-Released Chemical Trails At Poker Flat, Alaska, Tianyu Zhan

All Dissertations

Sounding rocket campaigns ARIA I through ARIA IV, CODA 2, HEX 1, JOULE 1 and JOULE 2 all carried out at Poker Flat Research Range at Alaska, covering the geomagnetic condition from quiet to highly disturbed. Trimethyl aluminum (TMA) were released during the rocket flights to study the mesosphere and lower thermosphere neutral wind at high-latitude region. The results of horizontal neutral wind profiles are presented. The comparison shows that under disturbed condition the wind velocity is stronger and the jet feature at the bottom side of wind maximum with unstable wind shear is lifted to a higher altitude. Under …
