Campus Data

 
 

Lake Water Quality

Setup - Water quality monitoring on Campus Lake 9A at 6-hour intervals.

Sampling Site: Lake 9A, Zone B = Middle of eastern portion

Data Legend

Variable Abbreviation Units
depth depth meters
temperature temp degrees Celsius
conductivity cond microsiemens/cm
dissolved oxygen DO% % air saturation
dissolved oxygen DO ppm mg/liter
pH pH pH units

Data Notes

Conductivity is a proxy for the amount of dissolved solids, which affect a liquids electrical properties

Water Quality Disturbance Event

Background - Site preparation associated with the construction of Academic Building 3 resulted in breaking into the cap rock allowing groundwater to flow to the surface. In order to prevent flooding, this groundwater, and associated silt, was pumped into Lake 10A beginning Wednesday, October 7, 1998.

Goal - To determine if the puming of excess groundwater and associated silt into one of the campus lakes significantly affects lake water quality.

Setup - Water quality monitoring at various sites within lake 10A, the experimental lake, and within lake 9A which remains unaffected by pumping operations and is therefore used as a control.

Sampling Sites:

Lake 9A
Zone A = SE end next to BHG III
Zone B = Middle of eastern portion
Zone C = North end next to rip rap
Lake 10A
Zone D = East end next to library
Zone E = Middle next to silt barrier
Zone F = South end behind Physical Plant trailers

Secchi depth is a measure of water clarity. It is measured as the depth at which a white disk is no longer visible from the surface. The greater the Secchi depth, the greater the water clarity and the lower the turbidity (suspended solids)

Forest Plot Data

This database includes information for a 1-hectare plot used to study forest dynamics. The database includes two sets of data on tree diameters, an initial measurement, and a remeasurement approximately three years later. Each stem reaching the minimum size of 10 cm diameter is measured and tagged.

This plot is intended as a first example of what could be a network of plots in Southwest Florida.

Chlorophyll Profiles

Setup - Water quality monitoring and chlorophyll determinations at 3stations on North Lake. Measurements made at 1-meter depth increments from the surface to the nottom at each station.

Sampling Sites:

North Lake
Station 1 = Between two buoys located farthest to the east
Station 2 = Between two middle buoys
Ststion 3 = Between two buoys located farthest to the west.

Data Legend

Variable Abbreviation Units

Secchi depth Secchi depth meters

Secchi depth is a measure of water clarity. It is measured as the depth at which a white disk is no longer visible from the surface. The greater the Secchi depth, the greater the water clarity and the lower the turbidity (suspended solids)

Chlorophyll concentration is used as a proxy for phytoplankton biomass and is measured using
a ship-board fluorometer

CREW Amphibian and Reptile Monitoring

These data were collected on the CREW Land Trust. Drfit fences were established at the exact sites from a previous study, and followed for 18 months, documenting the organisms captured in funnel traps during an eight-day sampling period each month.
