Datasets

This dataset shows the stream depth, conductivity, discharge, and temperature of the Wappinger Creek. Looking at abiotic factors such as stream temperature, stream depth and conductivity can indicate the health of the stream as well as the surrounding land.

Using data from the Hudson River Environmental Conditions Observation System (HRECOS), you can track the storm and its effect on the river.

Hurricane Irene caused extensive flood and wind damage as it traveled across the Caribbean and up the East coast of the United States.  Using data from the Hudson River Environmental Conditions Observation System (HRECOS) you can track the storm and its effect on the river.

Using data from the Hudson River Environmental Conditions Observation System (HRECOS) you can look at the impact of drought in the Hudson River by comparing two years with different PDSI scores.

The glass eel is the juvenile life stage of the American eel. This is a simplified dataset created from the full data collected by the Eel Project.

Groups from Manhattan to Troy collect a variety of river data including salinity, dissolved oxygen, turbidity, and fish abundance.

When scientists do a 'budget' of a water source, it helps to think of a bank account.  You want to know how much goes in, and how much goes out, of your bank account.

Organic matter that is washed onto the shore, or "wrack," is an important part of shoreline ecosystems because it provides habitats for macroinvertebrates and nutrients for both terrestrial and aquatic ecosystems.

The DEC collected a variety of fish in the spring, summer, and early fall when eggs, larvae, and juveniles are more plentiful. This dataset shows their results for tomcod, striped bass, rainbow smelt, and American shad.

Litter was collected from two marsh plants: Phragmites australis (common reed) and Typha angustifolia (cattail). Microbial productivity was measured for both bacteria and fungi.

These data show the populations of Atlantic silversides, blue crabs, ctenophora (comb jellies), striped bass, banded killifish, pumpkinseed fish, spottail shiners, and sunfish compared to dissolved oxygen (DO) in the Hudson River.

These data show the fecal indicator bacteria (Enterococci) and rainfall amounts at five sites along the Hudson River.

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.

Wastewater enters the Hudson River from point sources including municipal and industrial wastewater treatment plants, combined sewer overflows, urban storm water, and tributaries of the Hudson River such as Fishkill Creek.

Dissolved oxygen (D.O.) is an important measure of water quality and can be used to predict information about the local community of organisms.
