Adam Scott CVI & Clarington Central SS - 2019

This week on campus we hosted students from Adam Scott Collegiate Vocational Institute and Clarington Central Secondary School from the Kawartha Pine Ridge District School Board. The students were introduced to the local marine environment through field excursions and hands-on labs. Below are a few photos from our exciting week of learning!

Collecting data on the water temperature and salinity while on the research vessel, the Fundy Spray. The water temperature was about 12.5 Celsius. Brrrr!

Plankton collected on the boat and ready to be analyzed in the lab.

Drawing plankton.

Identifying the plankton species.

View of phytoplankton at 100x.

View of  zooplankton & phytoplankton at 40x magnified. Lots of copepods!

Morning lab studying marine invertebrate classification.

Drawing and describing the live animals.

Using a dichotomous key and field guides to identify the animals.

Some of the animals collected by the students and used in the classification lab were an armoured shrimp, a scallop, a blood star,

a toad crab, a common sea star, 

a sea anemone and a Stimpson's whelk.

The collected animals are kept for the week in tanks of flowing seawater that is pumped from the bay.

Beautiful feeding sea cucumber!

Right whale! The students had a great whale watching trip with Quoddy Link Marine. They were able to see all four large whale species that frequent the bay: right whale, humpback, fin and minke, as well as, harbour porpoise, harbour seals and grey seals. Here are a few updates, photos and videos from the Quoddy Link Facebook page: 1, 2, 3 & 4.

A presentation in the theatre about the amazing life cycle of lobsters. Do you know how to tell if a lobster is a lefty or a righty?

Studying the external anatomy of sea urchins.

View through the microscope. You can see the green spines, the purple tube feet, and a few white pedicellariae (pincers).

Learning how to handle the animals properly.

One of the sea urchins caused quite a stir when it started releasing sperm into the water during the lab!

 Here is a view at 400x!

Behaviour lab: how does temperature affect the feeding rate of barnacles?

Students had to count the number of times the cirri extended in temperatures ranging from 5 - 25 Celsius.

Behaviour lab: does size affect the flipping rate of sea stars?

Some groups also looked at the flipping rate of different sized sea urchins.

Exploring the intertidal zone at low tide.

Students found rock gunnel fish!

Lots of animals hiding under the rocks, including sea stars.
 
The students also found lots of green crabs.

Last morning in the lab. Making dichotomous keys of seaweed collected on Grand Manan Island.

Observing the diversity of seaweeds.

Bell High School - 2019

This week on campus we welcomed students from Bell High School of the Ottawa-Carleton District School Board. The students explored marine biology, life in the maritimes and a bit of history around St. Andrews and Grand Manan Island. Below are a few photos from their travels in New Brunswick.

On the research vessel, the Fundy Spray, sorting and counting benthic invertebrates.

We found sea stars.

We also found scallops, from tiny...

...to huge!

Plankton collected while on the research vessel.

Having a look a the plankton using the microscopes.

Copepods are a very common zooplankton. Viewed at 40x magnification.

There are many different species of phytoplankton. Viewed at 100x magnification.

Its always amazing to see the life in a drop of seawater!

Learning about lobster fishing with Captain Peter on Grand Manan Island.

Exploring the intertidal zone at low tide.

There were lots of animals hiding under the rocks in the tide pool!

Collecting a few animals to study in the lab.

Squeals of delight when the students found crabs!

Walking across the sand bar to Ministers Island. At high tide this bar is covered by water and the island is only accessible by boat.

Touring the barn at Ministers Island. A brief bit of history mixed with the marine biology. The island was the summer estate of Sir William Van Horne starting in the 1890s. He was an important person in Canadian history and was instrumental in getting the railway completed across Canada. 

Drawing, describing and identifying invertebrates collected throughout the week.

This female crab with eggs was found at the beach. 


Beautiful brittle star!

Students divided into groups to work on five different behaviour experiments. These students were testing the strength of sea stars, urchins and blood stars.


Testing to see if temperature affects the feeding rate of barnacles.

Does size affect the flipping rate of sea urchins?

Or sea stars?
