Collecting algae has motivated me to explore the great outdoors and visit
numerous watering holes--large and small, lotic and lentic, eutrophic and oligotrophic.
Large lakes are prominent features of the landscape but I find that small, inconspicuous
water bodies can produce distinct forms. Here are some of the sites on the
Keweenaw Peninsula that I have sampled.
These man-made canals and isolated puddles produced
some memorable specimens, particularly euglenoids.
This small bay on the Keweenaw
Waterway was a diversity hotspot. I have sampled it
frequently and still hope to re-encounter some of the rarer
Here is a lake located just out of
town that contained typical taxa for a lake.
The clear and cool waters of this
creek did not support a visible diatom biofilm, but tuffs of
aquatic moss and filamentous algae were found attached to rocks
This small pond produced some
interesting algae. Moyle has always been
gracious in granting permission to sample.
Here is a clear and cool water
trout stream with low productivity, but tuffs of filamentous
algae were found attached to rocks in riffles.
old Laurium Dump
This small pond and stagnant puddle
was especially rich in xanthophyceans.
This small pond produced a few
specimens but rotifers usually overwhelmed the plankton samples.
pond #1 marsh
These ponds tended to have greater diversity than
the nearby Swedetown Pond.
old Superior Mine
Here is another shallow and
eutrophic pond. Sometimes it stunk of decomposition.
algae in pond
The aquatic vegetation of this pond
and its drainage to the Keweenaw Waterway held many forms,
The acidic waters of this
Sphagnum bog was a diversity hotspot,
most notably for desmids and cyanobacteria, and I have
returned here repeatedly.
This river was a great place to
find diatoms attached to rocks and aquatic vegetation.
South Entry from boat
This shipping canal bisecting the
Peninsula provides numerous sites for sampling. I have
often stopped at the waterfront for a quick sample.
It was years later that I first
sampled this large but relatively shallow lake, and was quite
surprised to find its rich desmid community.
In 2010, I expanding sampling to new locations.
Here are some of the exciting locations I have discovered.
