Ashbury College - Day 3

With high tide in the morning the students began the day in the lab observing the invertebrates they collected from the beach and while on the research vessel.  During the lab the students did drawings and descriptions of the invertebrates, such as whelks, green crabs, bread crumb sponge, sea peaches, urchins, and sea stars.  This lab was fun because it gave the students a chance to see the animals up close and also to observe their movement. 
 
Just before lunch when the tide was going down the students headed to the beach on campus to mark periwinkles for their mark and recapture lab.  Each group chose a home base along the seaweed line and marked 25 periwinkles with bright nail polish.  After 24 hours the students will return and count both marked and unmarked periwinkles in their home base to get an estimate of the population.    
 
In the afternoon the students learned that at the Huntsman Worms are Winners.  Armed with buckets and shovels the students headed to Pottery Creek, a muddy beach.  They were amazed to find a great diversity of marine worms including clam worms, blood worms, milky ribbon worms, and opal worms.  They were also amazed to find that some of the worms have teeth and can bite.  A good life lesson!  While in this location the group also became master crab hunters and helped gather data on the invasive green crabs.       
 
To finish up the afternoon the students had a talk from Dr. Roxanne Gillett on Right Whale Conservation Genetics.  She described the significance of collecting the whale feces to determine genetics. 
 
In the evening the group met in the lab to focus on the echinoderms.  The students used the microscopes to observe some of the smaller parts of the sea urchins and sea stars, including the madreporite, the pedicellaria, anus, and the tube feet.  A treat was getting to see the urchins pooping!

Ashbury College - Day 2

Tuesday was the big trip to Grand Manan and the weather was great.  The group left campus fairly early with their pack lunch to catch the ferry in Blacks Harbour.  While on the ferry the students conducted a transect line marine mammal survey.  They were to keep an eye out for whales and whale blows in the distance, as well as, seals, and porpoise.  The only animals to be seen from the ferry were harbour porpoises.
 
Upon arrival on Grand Manan Island the group left the ferry to board a local whale watching boat.  The group had a fantastic trip and saw approximately 10-15 fin whales, 9 humpback whales, 17-18 Atlantic white-sided dolphins (which are quite rare), grey seals, as well as lots of seabirds, including puffins, shearwaters, and razorbills.     
 
Below are some of Mr. Greig’s pictures from the trip.

Ocean Appreciation Week 2 – Young Explorers

We had a lot of fun with the students that attend the last Young Explorers program for the summer.  This morning we painted some treasure boxes and then headed to the beach for an intertidal scavenger hunt.  The students were allowed to keep a couple of shells and rocks to put in their treasure boxes to take home.  After lunch we played shark and herring, made a Popping Porpoise craft, played a game about overfishing (then got to eat the gummy fish!), painted patterns on humpback whale tails, and did an aquarium scavenger hunt.  Also, the students got to spend some time exploring the animals that live in the touch pool and the skate tank.

Below are a some pictures from our fun day.

Ashbury College - Day 1

Sunday evening a group of 29 students and 4 teachers from Ashbury College arrived at the Huntsman campus from Ottawa, and settled into Needler Hall.  They were excited and ready to start their weeklong immersion into marine biology Monday morning when they met with the Huntsman Education staff for their introduction to our facility and the area. 
 
For the day the group was split into 3 groups to rotate through a trip on the research vessel the Fundy Spray, the plankton lab, and the tour of the Fundy Discovery Aquarium.  The students got a treat at the aquarium, as they were the first school group to see the new seahorse exhibit.  They also got to view live animals that are native to the Bay of Fundy including harbour seals, lobsters, and wolffish, as well as, touch the skates, rock crabs, and a number of other animals in the touch pools.
 
While out on the research vessel the students collected plankton to use during the plankton lab.  The boat crew also conducted a number of scallop drags to allow the students to see, touch, and collect firsthand the animals they will be using in their labs the rest of the week.  The animals they collected included scallops, sea urchins, sea cucumbers, hermit crabs, sea peaches, and sea stars.  Some of the brave students also had a taste of fresh from the ocean (i.e. raw!) scallop that they caught.  The girls were definitely braver than the boys!  A secchi disk and a salinometer were used to gather data on the light penetration, temperature, and salinity of the water.   
 
During the plankton lab the students used the microscopes to view the live phytoplankton and zooplankton they collected.   They drew, in fine detail, a number of different diatom species, as well as lots of copepods and other zooplankton.    
 
Yesterday the students also visited the beach at Indian Point to see how many phyla of animals they could discover living in the intertidal zone.  Hiding under rocks and seaweed they found green crabs, sea urchins, sideswimmers, and sea stars, above the rocks they found periwinkles and lots of barnacles.  The students that found the greatest diversity won some yummy local Ganong chocolate!  An important lesson some of the students also learned while visiting the beach was that their boots are only waterproof to the tops! 

After a yummy supper at Anderson House the students received a presentation from Danielle Dion, a biologist with one of the local whale watching companies, in preparation for their whale watching excursion today to Grand Manan.
 
Below are some pictures from Ashbury’s first day at the Huntsman Marine Science Centre.

Ocean Appreciation Week 1 – Young Explorers

Yesterday’s Young Explorers program was all about helping the students gain a greater appreciation and understanding of the ocean.  To help the students learn more about the different areas of the ocean and the animals that live in each area we played 3D ocean bingo, with marine creature tattoos being the prizes.  Then we collected some creatures from the touch pool to study.  Each student made field guide pages, complete with drawings, names, and descriptions of the animal they were observing.  Some of the students were very brave and picked up hermit crabs and rock crabs for the first time!  It was a great day!  Below are a couple of pictures from the program.

To register your child for the last Young Explorer program on August 28 call (506) 529-1200 or email huntsman@huntsmanmarine.ca.
