Products

Maps, Tools & Applications

NCCOS developed the Algal Bloom Monitoring System to routinely deliver near real-time products for use in locating, monitoring and quantifying algal blooms in coastal and lake regions of the US. This application delivers a suite of bloom detection products in the form of geographic based images. At this time products are available for selected regions. New products are being evaluated, and new regions are being considered; as they are proven useful, they will be made available through this system.

This digital atlas, supporting the proposed Wisconsin – Lake Michigan National Marine Sanctuary, shows the location of cultural resources, environmental research and monitoring, and human activities. It allows managers, stakeholders, and the general public to see the location of important lake resources and how these resources are distributed relative to one another. The atlas was created to identify data gaps, help prioritize future lakebed surveys, and support a better understanding of the Lake Michigan ecosystem.

Data & Publications

A Manual of Previously Recorded Non-indigenous Invasive and Native Transplanted Animal Species of the Laurentian Great Lakes and Coastal United States

This manual presents geographic information by state of occurrence, and descriptions of the socio-economic impact created by the invasion of nonindigenous and native transplanted animal species in the Laurentian Great Lakes and the coastal waters of the United States. It ...

Aquatic invasive species transport via trailered boats: what is being moved, who is moving it, and what can be done?

Trailered boats have been implicated in the spread of aquatic invasive species. There has been, however, little empirical research on the type and quantity of aquatic invasive species being transported, nor on the efficacy of management interventions (e.g., inspection crews, ...

Assessment of ecological condition and stressor impacts within Great Lakes rivers and harbors: Milwaukee estuary, Wisconsin

The Great Lakes, the largest surface freshwater resource in the world, has long been recognized for its valuable natural resources and services vital to the wellbeing of our nation. In 2012 a probabilistic sampling component was included under an expanded ...

Eurasian watermilfoil fitness loss and invasion potential following desiccation during simulated overland transport

Vegetative reproduction promotes human-mediated dispersal of aquatic invasive plants as fragments “hitchhike” between water bodies on boats and trailers. However, desiccation of plant fragments may also reduce fitness, decreasing the likelihood of fragment survival as transport distances increase. Current inter-lake ...
