Strawberry Isle Research Projects:
Grice Bay Gray Whale Feeding Ground Research
Overview
In May of '95 we started a monthly monitoring of sub-bottom organisms
in the Gray Whale feeding ground at Grice Bay. The methods used for
this project continue to evolve. Advisors receive copies of the resulting
field data in report form. Our work in Grice Bay is done under a permit
from Canadian Parks Service.
Methods
Every month we take nine core samples from the Gray Whales feeding
ground in Grice Bay. Sampling is carried out by divers using an air
lift that extracts a core 13 cm. In diameter by 20 cm. deep. The air
lift deposits the sample through a 1 mm. mesh plankton net. The remaining
sample is then sorted into phylum and counted. Unidentified specimens
are shipped to taxonomist Dr. Ken Low for identification. This work
is carried out with a boat driver, diver and deck hand aboard the 8-metre
vessel "Punt." The diver and boat tender are SIRS' staff
while the deck hand is a volunteer. This project is done under permit
from the Canadian Parks Service. Back at Strawberry Isle the field
notes are entered into a data base then distributed as a report as
described in the introduction.
The purpose of this study is an attempt to find out what happens
in the food chain to trigger the Gray Whales to, on occasion, utilize
the bay as a feeding ground. A significant aspect of this study is
that it is establishing some year round, baseline, data about the
bay
that could prove invaluable in the event of a natural or human induced
disruption. All samples are marked, preserved in formalin and stored
for possible future examination by whoever may be able to use them.
A significant component of the food chain is Ghost Shrimp, two speciments
