2005 Data Files

General Note: Snapshot Day Participants 2005 faced residual effects of Hurricane Tammy as they collected data. Weather conditions ranged from wet to wetter. Driving rains dumped inches of rain throughout the Hudson Estuary. Piermont area received 3.9 inches of rain during the day and Manhattan received 4.26 inches of rain, a record rainfall amount for one day according to the National Weather Service. Flood Watches were in place for much of the participating area.

In some instances participants had shelters where they could huddle and perform test. In other areas they used school buses as a base of operations. Still others ran quick tests in the driving rain and headed home. A few schools unfortunately had to cancel their involvement and look forward to next year.

While the data collection was less comprehensive in some locations than in prior years due to the poor weather conditions, dedicated students, teachers and environmental educators did a remarkable job of gathering baseline information in all reaches of the estuary. The rainy conditions actually offer a unique set of factors which can be used in data examination:

• Examining how temperatures changed, both air and water during the course of the day. Did they change together? Did one change more rapidly than the other? Why or why not?
• What happened with Dissolved Oxygen in some reaches of the river?
• What was turbidity like in the river system?
• What happened to salinity levels, and the salt front, which had been recorded at RM 71.6 on 10/1/05.

These and other questions make this year's data interesting to consider.

Preliminary 2005 data is available here 10/24/05. More data will be loaded and site sketches and photos added.
