The East River has so far rolled through this winter unadorned by a white speckling of sea ice (photos here are from 2015). On the Hudson River, bald eagles and seals have no ice floes to ride from the foot of the Palisades to the skyline. HarborLAB volunteer Thomas Dieter, director of CUNY Start at LaGuardia Community College, relays his observations from his home in Hunters Point South:

“We haven’t spotted ice yet this winter, and at this point I’m guessing we won’t. From our apartment at Hunters Point South Park, we can see that the inlets and coves just north of Newtown Creek haven’t iced over. In the past, the inlet where the ferry docks and the cove south of the fishing pier iced over at some point–but no such luck so far this year that we could see…The water in these areas doesn’t move as quickly as the river, and it’s far shallower, so I expected ice to collect there again this January and February.”

Our local disappointment echoes the vanishing polar sea ice aspect of the global climate change crisis, though some seek to take advantage of it for undersea fuel extraction, military maneuvers, and shipping. The National Oceanic and Atmospheric Administration’s Arctic Report Card on sea ice, glaciers, snow cover, temperatures, indigenous cultures, and animal health is profoundly grim. A special concern is ocean acidification in the Arctic, which is undermining the regional ecosystem’s less diverse food chain.

Scientific American/Climate Central report that winter sea ice at both poles has retreated to record lows. This is a sharp reversal from a record Antarctic peak last year, but a continuation of a trend of historic lows in the Arctic. Ice sheets ashore — notably in Greenland — are shrinking and thinning too. Winter heat waves are lashing the Arctic as warm air pushes north.

Seedball Making at LaGuardia Community College!

Hurricane Sandy, pollution, and development have stripped away much of our dune and coastal meadow habitats, so HarborLAB is joining the effort to restore them! To this end, HarborLAB and other conservationists are following Permaculture farmers in adopting an ancient Japanese and North American no-till agriculture tool that mimics the natural dung distribution of seeds (called endozoochory). It’s simple: make a ball of clay, compost, and seeds and toss them over the area to be revived. The warmth and rains of spring and summer then signal the seeds to germinate. Before long we’ll green the shores of NYC by bombarding them with seed love from our armada of kayaks and canoes!  😉

HarborLAB volunteers learned the art from SeedBall NYC‘s Co-founder and President Anne Apparu in a room made available to us by Dr. Sarah Durand of the Natural Sciences department at CUNY LaGuardia Community College. We made several hundred seed balls, and will make thousands more! The trick is to get the proportions right so that the balls hold together firmly but dry out before the seeds germinate. In terms of consistency, think cookie dough.

Another great instruction resource comes from the Lady Bird Johnson Wildflower Center.

HarborLAB used seeds we gathered with Hunters Point Community Middle School and Dr. Stephen Grosnell‘s Baruch College conservation biology students from Gantry Plaza State Park, Hunters Point Park, and our own GreenLaunch, along with seeds provided by SeedBall NYC and Briermere Farms. Hunters Point Parks Conservancy Vice President Mark Christie kindly help guide us in our seed gathering. Species included aster, milkweed, beach plum, beach pea, goldenrod, viburnum, pine, switchgrass, pokeberry, and the humorously named panicgrass (gallery below). These salt-tolerant species support endangered monarch butterflies and other pollinators, and feed birds. They also stabilize the shoreline, allowing complex ecosystems to develop while also protecting property from surges and erosion. We also gathered beach rose from Hunters Point South Park but must be very careful about where to use them, if at all, for biological productivity without enabling invasion.

See Newtown Creek Alliance historian Mitch Waxman‘s great write up of one of our outings at Queens Brownstoner.

We’re also grateful to Maureen Regan, president and founder of Green Earth Urban Gardens for participating and to Gil Lopez, president and co-founder of Smiling Hogshead Ranch Urban Farm, for inviting a naturalist to join us. We also thank the New York State Department of Parks, Recreation, and Historic Preservation for permission to gather seeds. An especially welcome newcomer was Philip Anthony Borbon, a sailor who moors on the Queens waterfront of the Newtown Creek.

Our next step is to go into classrooms to make seedballs with kids, and to then bring the balls with us when we paddle to areas in need of habitat restoration! If you’d like a classroom talk and seedball making activity with HarborLAB, please email us at edu@harborlab.org!

East River Ice Floes and “Ice Bridges”

The East River and its branches, like the creek, are saltier and so don’t freeze as easily, but perhaps the creek’s water treatment plant’s outflows and street runoffs are freezing?

Ice floes on the East River are a rare sight in recent years, but the Brooklyn Bridge is a daily reminder of how extreme even relatively recent planetary climate fluctuations have been. Let’s explore how that is so, and take a fun detour into the molecular structure of water.

When scientists worry about climate change and global warming, they’re not ignoring the fact that Earth has experienced wildly different atmospheric compositions and temperatures over its 3.8 billion years as a living world. What we’re destabilizing, they worry, are the conditions that for 12,000 years have fostered the neolithic agricultural revolution and civilization itself.

Some worry that the more energy retained by the atmospheric system (global warming) through higher CO2 concentrations, the more chaotic it might become in mid-latitude coastal areas (our temperate zone) as we become a pass-through for storms that transport energy between the tropics and arctic. But just as a cold snap in one region or continent doesn’t refute the mounting evidence of global warming, it can be argued that we can’t say with certainty that storms like Hurricane Sandy are the result of warming.

That said, there are records, written and archeological, of worldwide changes that lasted years or even centuries. Might we enter another “Little Ice Age” like that of roughly 1300-1870? To get an idea of how severe winters of that period could be, several times the East River froze over. Brave souls walked over “ice bridges” from Brooklyn to Manhattan, but ferries vital to commerce were locked in place. After this happened again in the winter of 1866-67, businesses in our growing metropolis had enough and lobbied hard for a long-contemplated “Great East River Bridge” to keep commerce flowing in all weather. As it happens, the Brooklyn Bridge was completed in 1883, eight years after the East River last froze over solid. In a sense, the Brooklyn Bridge touches down on the shores of two boroughs and on the shores of two climatic ages. And we might have a Brooklyn Bridge because the Sun lacked spots!

A few things can cause the planet to cool. Some ascribe the deepest points of the Little Ice Age to the Maunder Minimum, a period sunspots and solar flares were extremely rare. Our sun is in a lull right now, but a 2012 NASA study found that recent solar inactivity hasn’t impacted our planet’s “energy budget” much.  A 2013 study by researchers with the National Center for Atmospheric Research (part of the National Science Foundation) and partners concluded that a Maunder Minimum redux wouldn’t save us from global warming.

Just as adding carbon dioxide, water vapor, and methane to the atmosphere can warm the planet, kicking up dust and soot can cool it. Volcanoes have caused global cooling, as perhaps have asteroids and comets (even beloved Halley’s Comet). Some people even advocate for “geoengineering” projects that would cool the planet, but implementation could bring their own disasters. Besides, Ocean acidification, which could collapse the planetary ecosystem, would proceed apace if we continue to burn fossil fuels, even if we dust up to cool down.

Finally, a fun thing to ponder: What if ice didn’t float?

HarborLAB is very grateful to NY Waterway for its exceptional generosity in providing a special City of Water Day ferry for our boats and volunteers to reach Governors Island in time to provide services. Storms threatened to disrupt the day, according to forecasts earlier in the week. Because we were to commence the public kayaking program on Governors Island at 11AM, we didn’t have the scheduling luxury of “playing it by ear.”

NY Waterway is a sponsor of both HarborLAB and the Metropolitan Waterfront Alliance, which produces City of Water Day. The company also runs special ferries from Manhattan to Governors Island in support of City of Water Day.

When HarborLAB Founder Erik Baard called NY Waterway CEO Arthur Imperatore and Operations Chief Alan Warren to explain our worries, they kindly offered a special East River Ferry to get our volunteers, educational literature, boats, tables, canopy, and other needed items to the island before 10AM. This also saved us the trouble of delivering some items to City of Water Day producer Metropolitan Waterfront Alliance’s offices in Manhattan. HarborLAB extended this offer to Green Shores NYC, LIC Community Boathouse, Newtown Creek Alliance, North Brooklyn Boat Club, and other waterfront and environmental groups. We were happy to bring longtime Friends of Gantry Plaza State Park and Hunters Point Library community leader Mark Christie among our fellow passengers, along with Claudia Coger, President of the Astoria Houses Tenants Association (thanks to NYCHA Community Outreach professional Howard Hemmings).

The ferry captain and crew members were very courteous and kind, and quick!  Our gratitude to them too!
