The sequence of events leading to record harmful algal blooms in the Indian River Lagoon ecosystem in March 2016. Over 100 tons of fish were killed.
A deadly sequence of events in Florida
A graph depicts the low oxygen levels and high ammonium concentrations in 2005 that caused large algae blooms. This put more stress on the ecosystem, resulting in the fish kill.
2005 Corsica River Fish Kill
A graph depicts the increasingly high levels of hypoxia in the Chesapeake Bay since 1970.
Trends in Hypoxic Volume Since 1970
A conceptual diagram illustrates the current threats to native salt marsh species as well as the threats these species will face as their habitat is altered by climate change.
Effects of Climate Change on the Salt Marsh…
Conceptual diagram illustrating the contributing factors toward a healthy and eutrophic ecosystem.
Healthy vs. eutrophic ecosystem
Conceptual diagram illustrating how phytoplankton blooms in eastern Florida Bay and southern Biscayne Bay were sustained through feedback loops among ecosystem components.
Phytoplankton bloom feedback loops
Conceptual diagram illustrating the phosphorus cycle.
The phosphorus cycle
Conceptual diagram illustrating an interpolated measure of oxygen in the Lagoon of Venice.
Dissolved oxygen in the Lagoon of Venice
Conceptual diagram illustrating the carbon cycle relative to waterways, and the organisms that live there.
The carbon cycle
Conceptual diagram illustrating the inputs and processes that are a part of the phosphorus cycle.
The phosphorus cycle
Conceptual diagram illustrating how climate change affects human health.
Climate impacts on human health
Conceptual Diagram illustrating the process that creates low oxygen levels in an estuary.
Hypoxia
Conceptual diagram illustrating the affects of climate change on the habitat of striped bass in a coastal/marine ecosystem.
Squeeze Zone for Striped Bass
Conceptual diagram illustrating how nutrients trigger large algae blooms, which decrease oxygen.
Algal blooms result in low oxygen
This conceptual diagram depicts the environmental factors that lead to harmful algal blooms in the Potomac River. The diagram compares ideal bloom conditions to poor bloom conditions.
