Primary productivity is a term used to describe the rate at which plants and other photosynthetic organisms (producers) in an ecosystem use sunlight or other energy sources to build organic compounds like sugars. This is important because producers feed the other organisms in the ecosystem, which are called consumers.
Estuaries are among the most productive marine ecosystems, yet their productivity level fluctuates greatly through the seasons and in different parts of the estuary.
Using data from the Hudson River Environmental Conditions Observation System (HRECOS) you can look at how primary productivity changes daily and over the growing season. HRECOS uses automated sensors to record real-time data on Hudson River conditions (temperature, dissolved oxygen, etc) and weather (rainfall, wind speed, etc.)
