• February 04- Not available at the time this data was compiled. Will be available upon request.
• Other Notes: Floatable debris spotted- 80%, Oil slick- 85%, Illegal Discharge at one site- 90%, Thermal Discharge at one site- 75%, Foreign Materials Deposite to the Canal one site- 100%.
• A school of adult size Stripebass and Blackfish were spotted and documented on video in October 2003.
• Silversides commonly spotted in schools of hundreds were scarce through out the summer. Some spotting began in october, in small numbers.

EQUIPMENT USED: a) YSI 85 Probe/Meter- DO, Temp, Salinity, b) Lamotte Chemical Test Kit- pH, c) Phosphate, Nitrate d) Secchi Disk- Turbity, e) Video Camera and Photography Camera f) Observation Tank (fish monitoring) g) Minnow Traps ( fish collection and release) Vessels: Gowanus Monitor II, The Monitor NY At times collections are made off the bridges using an industy standars water collection bottle.
