plankton friends

In the early aughts I had a job running education programs at the Lower East Side Ecology Center.  I was tasked with interpreting the East River ecosystem, a tidal strait within the NY/NJ Harbor Estuary, for city kids and passersby on the East River Park Esplanade.

It was a great job. GREAT. And I wanted to keep it. So I went diligently searching for any foundational literature, research historic or ongoing, existing curricula, anything about the East River that I could base my programs on.  I was petrified when I found…nothing. For the East River, the only flora and fauna that people seemed to write about were of the forensic variety.  Only its sullied reputation preceded it.

I heard about one guy down at Pace University, who had been doing water and plankton sampling on a weekly basis “since 1989 or so” from the South Street Seaport. It was technically the Upper Harbor, but it would have to do.

So I cold called Dr. Michael Levandowsky, and he was kind enough to take me along.  He introduced me to the supreme scientific instrument, the Bucket on a Rope. (I went on to require all my classes to repeat after me in unison, “YOU DON’T. LET GO. OF THE ROPE!”) He also showed me the Winkler titration method for measuring Dissolved Oxygen, how to assess salinity with a refractometer, and how to run a plankton tow.

So when I returned to thinking and writing about plankton a decade later, I thought I would check in with Dr. Levandowsky. Again he was kind enough to take me along.

Today he is working, among other places, uptown at the American Museum of Natural History, in the Sackler Institute of Comparative Genomics, where he smashes his poor plankton samples into a slurry of genetic information and runs them into gels that he can read with greater accuracy than the method he’s used for most of his career (morphological identification through a microscope).

On his bench were samples from all over the world, and in the lab were an international crew of colleagues studying various aspects of planktonic – and other – life.

Despite the uptown digs and new fangled genetic analysis, I suspect that the Bucket on a Rope is still integral to the work…

Fung Lim at North Brooklyn Boat Club reported to me at my post at Newtown Creek Alliance that the ever-troubled creek had turned a dramatic shade of dark red. We went looking for answers:

Randall Austin from NYSDEC – “Conditions would be right for an algal bloom: rainfall (runoff) followed by a “heat wave” – would kick up the algae count…these normally occur at the end of the Summer when the ambient water temp has risen gradually. It can happen under the recent weather circumstances, though.”

John Lipscomb from Riverkeeper – “Yes we see it often in summer during sunny dry spells. I was on Newtown Creek last Friday and we saw it then.”

In conclusion, phytoplankton eat sewage and love sunshine.

returning dream

Last night I had a dream that we were testing a new plankton sampling tool, a large syringe more or less the size of a rocket launcher.  It had a bristly filter inside that slid out looking like a core sample of sea life.

In the dream I visited the lab of Holly Porter-Morgan and Sarah Durand, two professors at LaGuardia Community College in Queens, New York, near the Dutch Kills tributary of Newtown Creek. I have visited their lab in real life, but in the dream it was a future lab, full of new technology and gadgets that they were showing me.

In the second scene of the dream, I was walking over a marsh, and it was slow going in the soft mud. I looked at the plankton launcher and extruded its contents. Trapped in the bristles were many twinkling, turning creatures, some large and globby, others just specks of life.

It’s the first dream I can remember having in years.
