METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: 
	Drop freezing experiments consist of placing sample drops on a cold stage and observing the temperature of freezing of each 
drop as the stage is cooled.

2. Methods for processing the data: 
	Photographic records on 16 mm film were evaluated by trained personnel and the data transferred to spreadsheets.

3. Instrument- or software-specific information needed to interpret the data: 
	The data files are in simple ascii format and include a heading explaining the content of the tabulations

4. Standards and calibration information, if appropriate: 
none

5. Environmental/experimental conditions: 
laboratory

6. Describe any quality-assurance procedures performed on the data: 
	
control samples of distilled water

7. People involved with sample collection, processing, analysis and/or submission: 
	undergraduate laboratory assistants
