Stream and Lake Temperature Monitoring WorkshopNovember 5-6, 2012
“Monitor park ecosystems to better understand their dynamic nature and condition…”
Southeast Alaska NetworkInventory and Monitoring Program
“…leave them unimpaired for the enjoyment of future generations.”
- Organic Act of 1916
SEAN“Vital Signs”
1. Airborne Contaminants2. Freshwater
Contaminants3. Freshwater Water Quality4. Glacial Dynamics5. Intertidal Communities6. Kittlitz’s Murrelets7. Landform and Landcover8. Marine Contaminants9. Marine Predators10.Oceanography11.Streamflow12.Weather and Climate
Two rules:1) Monitor rigorously and sustainably
2) Serve high-quality data publicly

Site Visit Worksheet National Park Service - SEAN
Version 2012-04-24 Sonde Serial # 3100 National Park Road
(Check One) Juneau, AK 99801
Date of this visit 08H100353 phone: (907) 364-1541Operator 08H100354 email: [email protected]
Site name 08H100355
Physical integrity of site ok? If no, comment:
Sonde accessible? (Yes/No) If no, comment: (If not accesible, end worksheet here)
Time sonde pulled (hh:mm) Time redeployed:
Battery replaced? (Yes/No) If yes, did battery fail since last visit? Battery replacement: SOP 1, Section 9.2
Upload data to 650 MDS unit and scan most recent entries. Obvious that data quality is questionable? (Yes/No)
(Single Point Error Check with NIST-Certified or NIST-Traceable Thermometer; Calibration done by manufacturer prior to field deployment)
Water Temp (NIST thermometer)
Water Temp (YSI sonde)
Error 0
Within allowable error range: +/- 1? (Yes/No) If no, contact Project Leader for replacement.
Comments:
Standard Sonde Reading prior to cleaning and recalibration Within allowable error range? (Yes/No)
1413 uS/cm ref standard (between 1371-1455?)
100 us/cm ref standard (between 95-105?)
If allowable, specific conductance check completed. If not allowable, clean probe, and remeasure:
Standard Sonde Reading following cleaning Within allowable error range? (Yes/No)
1413 uS/cm ref standard (between 1371-1455?)
100 us/cm ref standard (between 95-105?)
If allowable, specific conductance check completed. If not allowable, ensure probe is clean, and perform recalibration:
SITE AND SONDE CONDITIONS

Five key lessons:1. Report regularly
2. Designate roles and responsibilities
3. Let the “customers” define reporting products
4. Provide data on a public website
5. Establish a single authoritative source
