NOAA’S ECOLOGICAL FORECASTING

Ecological forecasts use measurements of the physical and biological environment to predict ecological conditions that can impact natural resources, people, communities, and economies. NOAA aims to deliver accurate, relevant, timely, and reliable ecological forecasts that power the blue economy and build resilience. These products and services are made available to coastal managers, private industry, and the public.

Harmful algal blooms (HABs) Forecasts Hypoxia Forecasts

HABs occur in every state and are changing in Hypoxia (low oxygen) has dramatically increased in U.S. frequency, toxicity, and duration. Both toxic and non- coastal systems, with large “dead zones” in Lake Erie, toxic HABs threaten human and marine mammal Chesapeake Bay, and Gulf of Mexico occurring annually. health, drinking water, tourism, commercial and The consequences of such large dead zones include recreational fisheries, and aquaculture. Short-term massive fish kills, loss of fisheries , and economic HAB forecasts predict the intensity, location, and losses in commercially and recreationally valuable fishies. trajectory of blooms, and respiratory health risks of In Lake Erie, hypoxic water reaching the water intake for HABs in some areas. Longer-term forecasts predict cities along the coast can affect water treatment, the severity of HABs for the bloom season in a potentially impacting approximately 2 million residents. particular region. Scenario forecasts are used to test NOAA hypoxia forecasts aim to provide coastal managers the impact of changing environmental conditions, and stakeholders with the information needed to take such as nutrient pollution and , on HAB proactive action to mitigate the impacts of an ongoing occurrence over multi-year time scales. Forecasts and hypoxic event, and to set the nutrient reduction targets early warning allow effective mitigation of HAB necessary to reduce the frequency and magnitude of impacts and facilitate HAB prevention. future events.

Pathogen Forecasts Forecasting Shifts in Species and

Each year, an estimated 80,000 vibriosis illnesses and Climate change is driving shifts in the distribution, 100 deaths in the United States occur related to , and of coastal species and Vibrio bacteria. The majority of these result from associated habitats. Protecting and restoring these consumption of raw or undercooked seafood resources requires understanding and planning for the contaminated with Vibrio parahaemolyticus, or by impacts of climate change. NOAA has, and will continue, exposing a wound to seawater that is contaminated to advance our understanding on the sensitivity and with Vibrio vulnificus. NOAA’s Vibrio forecasts show resiliency of coastal habitats to coastal changes and where and when to expect elevated concentrations. forecast how will respond to various climate Shellfish growers use the Vibrio parahaemolyticus stressors. Thus, NOAA scenario forecasts are used to forecast to plan harvest and refrigeration strategies, test the impact of changing environmental conditions, allowing them to get more of their product to market such as sea level rise and temperature, over multiple and keeping consumers safe. The Vibrio vulnificus time and space scales. Results are used to prioritize and forecasts are used by public health agencies to guide site conservation and restoration initiatives and to monitoring, inform beach and fishing advisories, and inform the spatial management of living resources in to educate the public. estuarine, coastal, and marine waters.
