Water Quality Monitoring

Page 2: Florida Keys National Marine Sanctuary Steering Committee Meeting Marathon  2/20/2013

• Establish baseline information about FKNMS waters

• Document events, both chronic and episodic

• Assess trends or changes in WQ over time • Explain causes in WQ changes (internal & external driver)

• Provide relevant information for resource management decisions • Document compliance practices (regulatory)

•Educate public & stakeholders about water quality *

Monitoring Water Quality in FKNMS

Page 3: Florida Keys National Marine Sanctuary Steering Committee Meeting Marathon  2/20/2013
Page 4: Florida Keys National Marine Sanctuary Steering Committee Meeting Marathon  2/20/2013

EPA developed Strategic Targets for the Water Quality Monitoring Project

…”maintain the overall water quality of the near shore and coastal waters of the FKNMS according to 2005 baseline”…

– For reef sites• chlorophyll a should be ≤ 0.35 µ l-1

• vertical attenuation coefficient Kd ≤0.2 m-1

– For all monitoring sites in FKNMS• dissolved inorganic nitrogen DIN

≤0.75 µM• total phosphorus, TP ≤ 0.25 µM

TP has not changed a lot. It declined along west Shelf..a couple of stations increased!!

DIN increased in Tortugas and Marquesas..a couple of Sluiceways stations increased!!

Recent achievements….

Page 20: Florida Keys National Marine Sanctuary Steering Committee Meeting Marathon  2/20/2013

Biogeochemical Segmentation of South Florida Coastal and Estuarine Waters

Developed with data generated

from monitoring WQ since 1991

Adopted by EPA and FDEP with minor changes

for derivation of Numeric

Nutrient Criteria

Page 21: Florida Keys National Marine Sanctuary Steering Committee Meeting Marathon  2/20/2013

NOAA-IMPACT (Integrated Marine Protected Area Climate Tools) project is “ingesting” fixed-site data into IOOS and attempting to couple with remote sensing information.

NEW Proposal in preparation for NASA-ROSES

More work needs to be done with coupling monitoring with remote sensing technologies and coastal ocean observation systems
