Visitors to New York's Hudson River often comment on how "dirty" or murky its water appears. This murkiness is often taken as a sign of poor water quality. Why does the river look so muddy? And what does it mean?
Podcast Any time there are high flow events bringing water and sediments from the tributaries and over the dam, it causes several fairly dramatic changes. Podcast interview with freshwater ecologist Dr. Stuart Findlay.
We've all heard the expression, "Think global, act local." In the environmental context, its popularity no doubt comes from a sense of reassurance — that by taking small, personal steps, we can make a difference.
Cary Institute educators are challenging middle school and high school students to creatively bring long-term river data to life in the Hudson Data Jam, a new competition that melds science and creativity.
A pedestrian bridge in New York has a new sign unveiled this week featuring real-time data about the Hudson River. Officials say the information will provide some useful facts to visitors while scientists monitor the river’s changing conditions.
Each year, some half a million visitors explore the Walkway over the Hudson, a steel cantilever bridge that was converted into the nation's largest footbridge in 2009. And now, thanks to a new digital sign, visitors will be able to access real-time information about the river's environmental conditions.
In the Housatonic River, zebra mussels -- non-native bivalves that can move into a water body and just dominate it -- were found in 2009 in Massachusetts and in 2010 in Connecticut at Lake Lillinonah and Lake Zoar.
Freshwater ecologist and author of The Hudson River Primer – The Ecology of an Iconic River Dave Strayer, discusses the positive effects of the federal Clean Water Act and other government regulations with Radio Rotary.
A short documentary by the American Museum of Natural History. The video highlights zebra mussels in the Hudson River and the Cary research that closely analyzed the river before, during and after the invasion.
Humans have carelessly moved thousands of species outside their native ranges through activities such as transfer of ballast water, release of pets and bait, movement of untreated wood, escapes from agriculture and aquaculture, and deliberate release of species that we thought to be beneficial.
Losses of our local fish have been so severe that the New York State Department of Environmental Conservation has completely closed commercial and recreational fishing for American shad in the Hudson River.
As we commemorate the 400th anniversary of Henry Hudson's historic voyage up the Hudson River, it is prudent to learn what we can from the past in order to maintain and improve this irreplaceable natural resource for future generations.
A collaborative monitoring project called the Hudson River Environmental Conditions Observing System has been implemented to provide continuous real-time data about estuary conditions in the Hudson River such as temperature, salinity, and pollutant loads.
This past winter, the National Science Foundation renewed funding for the Institute’s long-term research on how the Hudson River is responding to zebra mussels. Introduced in 1991, the invasive bivalves are now the most abundant animals in the river. Institute scientists have generated the longest published record of this invasive species.
If you’ve walked much along the Hudson’s shores, you’ve probably seen thorny, black water-chestnut seedpods piled up along the high-tide line, thick stands of common reed in wetlands and along the railroad tracks, mute swans gliding across the water, carp splashing in the shallows, chunky shells of Atlantic rangia on the beaches of Haverstraw Bay, and the thin, sharp shells of zebra mussels littering shorelines from Newburgh north.
