2019 Hudson Data Jam Competition

Making data "sing" through creative expression

Now in its sixth year, the Hudson Data Jam Competition challenges students to creatively tell the science stories of the Hudson River watershed.

***Level 1: Zebra Mussel Populations

***Level 1: Zebra Mussel Populations

The zebra mussel datasets are in our set of highlighted projects, which means we've developed an expanded metadata file with more background information, resources, and sample inquiry questions. In addition, this dataset was updated this year to include results through 2014.

Invasive species pose a serious risk to ecosystem health and stability around the world and locally. Zebra mussels were first detected in the Hudson in 1991. By 1992 they had spread throughout the freshwater and slightly brackish parts of the estuary and had a biomass greater than the combined biomass of all other consumers (fish, zooplankton, zoobenthos, bacteria) in the river. The mussels filter the equivalent of all of the water in the Hudson River about once every four days.

We've assembled two zebra mussel datasets to help you examine the problem from different angles. The first, "Zebra Mussel Populations" (Level 1), simply shows the density of zebra mussels collected in the Hudson each summer for 28 consecutive years. The second, "Zebra Mussels & Other Organisms" (Level 2), allows the user to consider the living community zebra mussels have embedded themselves in. It includes annual measures of zebra mussels, unionid mussels, phytoplankton, and zooplankton.
