Transcript Presenting Scientific Work

Presenting Scientific Work
- Oral -
At some point in your career
You 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 across
a. why you’re doing what you’re doing
b. what you got
c. what you think it means
4.
Tell a story.

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

THE WORD ‘LIKE’ IS OFFICIALLY BANNED!!!!

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

Species
S.D.I.= 1-D

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