The term “snow pillow” evokes a peaceful, muffling moonlit whiteness spreading a lull across the countryside. For New Yorkers, however, it’s a critical piece of hardware.

Much of the billion gallons of water used daily by nine million residents of NYC and surrounding counties arrives as snow. The white caps of the old, rounded Catskill Mountains nestling the Neversink Reservoir are a reserve bank that melts to meet our needs in warmer months. Snow melt can also swell rivers, so anticipating flood risks is very important to towns an farms. With so many lives affected by snow, the NYC Department of Environmental Protection, in partnership with City University of New York and National Weather Service, is constantly looking for better ways to measure it.

At the end of the last decade NYCDEP began using “snow pillows,” essentially scales that weigh snow in remote locations and transmit data wirelessly in near real-time. The technology (first developed by the U.S. Army Corps of Engineers in Alaska) is often integrated into remote sensor stations in rougher terrains out west. The NYCDEP deployed its first snow pillow at the Schoharie Reservoir in 2008, and later near reservoirs in Cannonsville, Pepacton, and Neversink. HarborLAB operates a canoeing and kayaking program at the Neversink for NYC youth groups and public school students to learn about their drinking water sources.

The NYCDEP still uses aerial surveys and good old fashioned field work to measure snowpack, but the agency plans to more than double its constellation of snow pillows to 35 stations in coming years. Another sensor used is the Gmon, which helps researchers estimate snowpack by measuring the absorption of naturally occurring radiation. Future snow data collection might increasingly rely on satellites.

Sweet Sweep of the Creek!

HarborLAB volunteers, environmental science students from CUNY LaGuardia Community College, and a mix of visitors from other schools and walks of life had a fantastic time tending to the Newtown Creek on Saturday! Our work was part of the annual Riverkeeper Sweep of Hudson River and estuary sites from New York City to Albany. Our Newtown Creek home base is a waterway so blighted with pollution that it qualifies for the US Environmental Protection Agency’s Superfund cleanup program.

HarborLAB’s Newtown Creek Sweep had two basic components, cleaning and gardening. We offered a variety of activities so that people of all ages and abilities could participate. More than 30 people helped over the course of the day. We were especially grateful to have educators among us to add learning to the labor. Holly Porter-Morgan, Diana Szatkowski, Harald Parzer, and Thomas Dieter brought knowledge and encouragement to our students and volunteers.

The core of the program was removing plastics from our shoreline and the creek itself. Volunteers wend their way through broken bulkheads and boat lines to pick trash from the shores while our canoes went out in two waves to scoop up litter, mostly plastic bottles and bags. These smaller items filled seven large trash bags. Larger hauls included a lawn mower, two chairs, a 55-gallon steel drum, a bird feeder, and antiquated electronic sound systems.

We’re under no delusion that our cleanups will remove the tonnage necessary for an ecosystem rebound, but the exercise educates people about the severity of the plastics problem. So what works if picking up plastics is a measure that’s too little, too late? Recycling is also an inadequate solution by itself because it requires a great amount of energy (often from carbon-releasing fossil sources) and sustained administrative focus. With petroleum and other commodity prices low, private carters in New York City are recycling even less material than usual despite New York City’s public commitment to eliminating waste. While a reduction in unthinking, rampant consumerism is laudable, instilling new virtues across the culture will be a slow process. Real penalties and enforcement for littering will help a bit, but not enough. That leaves voters and activists to demand a reduction in wasteful packaging at the design and production stage. We must also push to eliminate combined sewer overflows, which gulch marine debris as well as pathogens and other pollutants.

Gardening was also a big part of the day, and is a huge part of HarborLAB’s work. Volunteers — especially a group from New Hyde Park High School — made thousands of native pokeweed seed balls that we’ll distribute as we land at rest stops on our harbor journeys across to stabilize shorelines, buffer storm surges and waves, feed birds, and sustain pollinators. Those up for heavier lifting helped restore our shoreline by layering cocoa husks from MAST Brothers Chocolate with burlap sacks, kitchen scraps, and soil in a system called “lasagna composting.” This fresh soil covers a broken brick substrate that mimics the glacially transported rocks of our region. The resulting slop will be planted with staghorn sumac, pokeweed, goldenrod, milkweed, and other indigenous species, and footed by smooth cordgrass and shellfish. Some of these species are already making headway. We were delighted to see that our dozens of shadbush saplings were fruiting copiously and our hackberry and American persimmon are also thriving. Our raised bed and container-grown dessert cultivars are doing great too, including apricots, apples, pears, and figs.

We’re tremendously grateful to all who came and helped, and to Riverkeeper for creating this unifying event and helping direct volunteers to sites.

Phragmites Tankwa?!?!

HarborLAB will commence its multicultural boatbuilding program in March with the International High School! We’re thrilled to serve these students, who are in an intensive college preparatory program for immigrant youth with limited English. IHS is housed within CUNY LaGuardia Community College.

We’ll make reed craft using invasive phragmites, which crowd out many of region’s indigenous estuary species. We’ll start with a demonstration inspired by the tankwa, an Ethiopian work boat made from papyrus on Lake Tana. Other models will follow, launching on June 8 for United Nations World Oceans Day. Our goal is for these boats to greet the arriving Hokule’a, a Hawaiian canoe circling the globe for environmental education. This is easily achievable at Gantry Plaza State Park, if permitted, directly facing the UN and a few minutes paddle from our launch.

We welcome volunteers to join the effort and donors to sponsor us!

Grass (family: Poaceae) and sedge (family: Cyperaceae) boats are among the most ubiquitous types because papyrus, bamboo, and reeds are renewable and readily available to those working the water as fishers, ferryers, and traders. Grasses and sedges also wonderfully pliable materials, providing both planking and twine. We’ll work with the United Nations community and immigrant cultural centers to maximize our inclusive service and multicultural representation.

This world heritage is truly ancient, as evidenced by petroglyphs depicting reed boats in Azerbaijan that date back 12,000 years. These boats quickly return to the soil, so archaeological evidence is spotty. Logic would indicate African origins. The earliest remains of a reed boat are 7,000 years old, unearthed in Kuwait. Palm fronds are also used in a similar fashion in the Persian Gulf. Even the story of Moses begins with him set afloat in a bulrush ark. The apexes of accomplishment in this art include ancient Egyptian papyrus voyaging vessels and the ornate craft of the living Uros culture of Lake Titicaca on the border of Peru and Bolivia. Our most famous reed heritage boat in North America is the tule (pronounced too-lee). Watch one get built in the video below!

On the East Coast, science writer and ecologist David Samuel Johnson proved the viability of phragmites boat construction. Even young students can build these boats.

Benefits of this project:
  • Environmental science education: Indigenous/invasive species, rhizomes, ecological services, estuaries, wetlands, etc.
  • Cultural and Economic Education: World heritages, commonalities and differences, economic development and identity, renewable resources and growth, etc.
  • Habitat Restoration: Tangible results from removing invasive reeds (and removing seeds before construction). New, native plantings would bring even more value.
  • Safety: No power tools are needed. Adults would maintain a good ratio and oversight of youth. All paddling would be done under HarborLAB insurance with Red Cross certified (Water Rescue, CPR, AED, First Aid, adult/pediatric) volunteers in safe areas. HarborLAB will provide safety support from sit-on-top kayaks, though these reed boats will be much more seaworthy.
  • Youth empowerment: Students will do much of the building, paddling, documentation, and outreach themselves.
  • Publicity: We’ll paddle these boats past the UN and skyline, generating great images and video. This would be a sight never seen on the East River. This is especially true if we are able to support the Hokule’a effort.
  • Budget: The materials are harvested invasive plants and twine.
  • Sustainability: The boats will last a season and then be composted to enrich planting areas for habitat or ornament (not edible gardens).
  • Outreach: The students, educators, organizations, agencies, and companies involved will trumpet this unique project, delivering some aspect of its value to wider audiences. The boats will be brought to communities throughout NYC.
  • Long-term Results: Thorough documentation will allow other educators to reproduce our results and build upon them. The excitement may seed the founding of a World Boatbuilding Museum (a place where the public can see small boats from around the world — reed, skin-and-frame, wood, and more) built before their eyes, and ride aboard them) that could be a major tourist draw.

If you’d like to volunteer with us and the students, please email volunteer@harborlab.org with the subject line “Boat Building.” To sponsor, please email support@harborlab.org.

 

Readying for Winter…and Spring! :)

Diana, Miyeon, and EJ at work on the second shed.

HarborLAB volunteers had an amazingly productive Sunday, and had lots of fun in the process! Our goals were to winterize our Newtown Creek waterfront site and prepare it for transformation into the GreenLaunch in the spring. It sure felt like spring already!

We assembled a second shed and platform, repaired “The Jenni” tandem Folbot kayak for use by Baruch College environmental science classes (named for our late friend and CUNY alumna, Jenni Jenkins), set up planters and protected fruit trees from root freeze with vinyl and bags of cocoa shells, gathered seeds (especially pokeberry, goldenrod, and milkweed) for habitat and shoreline stabilization, and protected public boats from UV degradation with tarps. We donated many bricks to Build it Green, delivering them by van. Our bricks, which are molded with holes, are being built sideways into walls in South Africa to allow air circulation.

Many thanks to Patricia Erickson, who directed the day’s work as HarborLAB’s facilities manager and chair of the GreenLaunch committee. A special acknowledgment to Shawn and Miyeon Cornell, who were married just this month and shared this special time with us as stellar volunteers. They are CUNY students, as is Diana Arias, another fantastic volunteer who threw herself into the work (we met her through the great Baruch College ECO Club). Rounding out the crew were Irene McLoughlin, Alessandro Byther (daring Alpinist of bricks and plastic heights), Jenna Nugent, Davis Janowski, Erik Baard, and EJ Lee (HarborLAB operations manager and a CUNY alumna).

Great thanks also to Schuman Properties for our launch and to Citizens Committee for NYC for the initial GreenLaunch project grant.  Much gratitude also to Folbot, Lamar Outdoors, Dorothy Morehead for our supplies.
