Status and Trends: LISS Environmental Indicators

Climate Change

Climate change indicators appear in different topic areas, and include physical, biological, chemical, and socioeconomic measures. The breadth of measures is because conditions affected by climate change such as sea level rise, temperature change, and increased ocean acidification can impact animals and plants and their habitats as well as humans throughout the region. These indicators help resource managers assess climate change's current impacts on the the Sound, and project future trends.

Warm Water/Cold Water Fish Index

The Warm Water/Cold Water fish index is an indicator of whether the fishery is sensitive to changes in water temperature, and to long-term climate change trends. View Indicator

Water Temperature

Yearly seasonal temperatures from 1976-2012, measured in Niantic Bay by the Millstone Environmental Lab. View Indicator

Sea Level Trends for Kings Point

The Sea Level Rise indicator shows the average sea level at a given point, over a year. View Indicator

Spring Freshet

The indicator tracks the time of the spring freshet (a measure of snow melt) on the Connecticut River to assess if there is a warming trend. View Indicator
