Presenting Scientific Work- Oral -
At some point in your careerYou will have to present scientific information
before a crowd that can be large or small
A Seminar
How to put one together
Some general considerations
1. You have a restricted amount of time
2. No one is especially interested in what you are saying You have to interest them!
3. You have to get acrossa. why you’re doing what you’re doingb. what you gotc. what you think it means
4. Tell a story.

Presentation Mistakes!!!
2. Annoying Mannerisms
• Um’s or other fillers
• Pacing (some is OK)
• Trailing voice - sounds like you’re very unsure
• Uplifted voice - sounds like you’re always asking a question
• Jargon - scientific or bureaucratic
• Jokes - they work so rarely that its not worth it
• Not maintaining eye contact

2. Annoying Mannerisms
THE WORD ‘LIKE’ IS OFFICIALLY BANNED!!!!
Ending a seminar
Thank the audience for their attention
End it!!

Results
• Figure 2: Mean Rock Composition and relative cover at all four sample sites.
Background Information
• Sediment characteristics reflect the salinity, oxygen content, pore-water content, temperature, food availability, sedimentation rate, substrate consistency, turbidity, and predation found in a particular environment
• sediment characteristics define what organisms can survive in the environment – Biodiversity: describes the sum total
variation of life forms in a specific environment.
Indian Point
• Transect placement
• Quadrate spacing
•Invertebrate and algal species collection and identification

Identified Unknown Species
Calculated Simpson’s Diversity D= 0-1 (high to low diversity)
n= count of particular speciesN= Total count of all species
S.D.I.= 1-D
Purpose and Hypotheses
• To relate wave exposure to diversity
• To measure range and abundance as related to wave exposure
• Moderate exposure= Most diversity
