My Essential QuestionWhat are the differences between plankton
populations in Port Angeles Harbor and the
Peabody Creek Estuary and how do these
differences reflect the health on the two
sites?

What I Knew Before Starting I knew the “basics” of plankton.
Types: Phytoplankton (plant-like) and zooplankton (animal-like).
What they were: Very small organisms that lived in water.
They are the base of the oceanic food chain.They are good for the environment.That whales eat them.

What I Didn’t Know Before Starting The definition of plankton.
Anything in the water column that is alive but can’t move of its own violation.
All the different types of plankton. Especially the types that live in our harbor.
That some types of plankton don’t stay plankton. Holoplankton stay plankton their whole lives. Meroplankton are plankton for only a part of their life
cycle.
Plankton can be bad for the environment. Red tide, dead zones, etc.

Personal Importance of the ProjectThis project is important to me because I love
Port Angeles and I wanted to do something that
would benefit the community. I felt that that Port
Angeles Harbor was important to the people of
Port Angeles so they should know about its
health.

Significance of my Project This project could help determine the health
of Port Angeles Harbor and the Peabody
Creek Estuary.

Works for Olympic Coast National Marine Sanctuary(OCNMS).
My project can be given to other researchers by Mr. Bowlby and also used to monitor recourses.
Bob Campbell Works for Feiro Marine Life Center. My project can help Mr. Campbell to create a
baseline plankton population in Port Angeles Harbor.

Procedure1.Gather materials, being sure that the
plankton net’s depth markers are at 3m and 5m.
2.Go to the City Pier site. Using data sheet record information.
3.Tie off excess rope to the railing. Take a water sample with the bucket. Record data.
4. Tie off excess rope to the railing. Take plankton sample. Put in sample jar.

ZooplanktonWhen we observed the plankton we couldn’t
count the number of plankton very accurately so we used the words “None”, “Present”, “Common”, and “Bloom”

What I learnedAs I looked at my data over the weeks I began to see
that neither of the sites was clearly healthier than the
other by looking at their plankton populations alone.
Both site’s plankton populations seemed very similar
in the types of plankton and the amount of those types
they contained.
![Page 34: By Mariah Crowley. My Essential Question What are the differences between plankton populations in Port Angeles Harbor and the Peabody Creek Estuary and.](https://reader036.fdocuments.us/reader036/viewer/2022070413/5697bfbf1a28abf838ca34a8/html5/thumbnails/34.jpg)
Personal Impacts I learned about the interconnectedness of
the oceans. How the health of a small area can affect the
whole ecosystem.
I now know how to sample and observe
plankton. Also I know how to measure pH,
dissolved oxygen, temperature, and salinity.
