Conceptual diagram illustrating the important ecological functions that mangroves provide to the marine environment.
Mangrove ecological functions
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 how water can detect contaminants, such as mercury, that can become biomagnified through food webs, and is toxic to consumers.

Conceptual diagram illustrating different monitoring activities implemented on Assateague Island to track changing habitats. Monitoring activities - which are habitat specific - include water quality, seagrass area, salt marsh nekton survey, surface elevation table, plover nests and fledgling success, upland elevation change, shoreline rate of change, and beach topography.

A Taylor float is used for Oyster Gardening for oyster restoration. The PVC tubing allows these oysters to grow near the surface of the water, above water that is potentially hypoxic (with little oxygen) or anoxic (no oxygen).

The 2008 Severn River Report Card Release. The report card summarizes 2008 water quality results, which are based on data collected by the Severn Riverkeeper Program. This report card helps to clarify the Severn's health, and provides instructions on what individuals can do to improve its condition. The release of this report card was attended by local, state, and federal representatives, Severn River Keepers, and IAN staff.
