GLEON: Ten years of linking lakes and people

In October 2005, five scientists were marooned on a mountain near Yuan Yang Lake in Taiwan. Dead-set on installing a new batch of water quality sensors, the group had ignored an incoming typhoon that washed out the only road behind them, knocking chunks of pavement the size of a garage down the cypress-covered slopes.

Q&A with Kathleen Weathers

Cary's Kathie Weathers is interviewed by the Environmental Monitor and answers questions about the Global Lakes Ecological Observatory Network.

Cleaning up with mussels


Zebra mussels are one of the most pernicious invasive species in the United States having infested the Great Lakes in the 1980s and then having spread to 29 states by hitching rides on boats on inland waterways.

For the Love of Rivers

Lecture Video

Author and award-winning ecologist Kurt Fausch has spent his career exploring threats to stream and river life. His new book, For the Love of Rivers, reflects on the deep significance of freshwaters to humanity and their ultimate fate in our future.

Road Salt

Increasing salt in our streams has been a concern at the Cary Institute for many years. Even in the relatively undeveloped watershed of the East Branch of Wappinger Creek, the salt levels have increased since 1985 when sampling began.

Dr. Weathers is co-Chair of the Global Lake Ecological Observatory Network (GLEON), a grassroots research network that conducts innovative science by sharing and interpreting high resolution sensor data to understand, predict and communicate the role and response of lakes in a changing global environment.

Increased Loss of DOC from Terrestrial Systems

Carbon released from terrestrial ecosystems is an important source of organic matter in most streams, lakes and rivers. In the Hudson River there has been a doubling in concentration of dissolved organic carbon over the past 15 years.

Zebra Mussels and the Hudson River

Zebra mussels appeared in the Hudson in 1991 and fundamentally transformed the ecosystem. The zebra mussel invasion is linked to losses of native mussels and changes in the fish community.

Hudson River Habitats: Submersed Aquatic Vegetation

Submersed aquatic vegetation (SAV) is an important habitat in the Hudson River. We have investigated a wide range of functions in SAV beds including maintenance of high dissolved oxygen, effects on suspended sediment, and habitat value.

Ecological Functions of Submersed Plant Beds

Beds of water celery (Vallisneria americana) and other plants are widespread in the Hudson River, and play several important ecological functions. These beds contain a diverse invertebrate community, which may serve as a major source of food to the river's fish.

Stream Bacterial Communities: When is Function Linked to Structure?

We have carried out a diversity of small and mesocosm-scale experiments, in conjunction with regionally distributed field sampling, to assess when the composition of stream benthic bacterial communities corresponds with differences in stream metabolic activities.

Hudson River Environmental Conditions Observing System

HRECOS provides continuous, real-time data on environmental conditions in the Hudson River. There are fifteen monitoring stations at eight sites, spanning from Albany to the New York Harbor

Hudson River Ecosystem Study

For three decades, our scientists have been researching the Hudson River ecosystem– from the way shoreline development impacts water quality to how invasive species influence resident plants and animals. As a result, the Hudson is the most scientifically scrutinized river in the world.
