Jon Knight, PhD.
Limnologist
Charlotte,
NC
email:
joncknight@adelphia.net
Professional
experience has covered a broad range of limnology, with emphasis
on physical (heat and mass transfer) and chemical (dissolved oxygen,
carbon dioxide, and nutrient) processes as related to plankton dynamics,
plankton bioenergetics, and suspended solids. Professional goal
is to establish valid limnological and ecological models for reservoirs
and associated downstream releases for use in establishing reservoir
management strategies. Current research activities center on the
role of water use patterns (intake and discharge structures), meteorological,
and land use (erosion and runoff), as influencing the physical and
associated chemical dynamics of reservoirs and rivers.
