Citizen Scientists Track Algal Blooms

Harmful algal blooms (HABs) are a global problem. HABs can pose a serious risk to human health.

Overview

Algae are natural components of marine and fresh water flora that perform many roles vital for the health of ecosystems. Cyanobacteria, also known as blue-green algae, are of special concern because of their potential impacts on drinking, fishing, and recreational waters.

Roles & Expectations of Citizen Science Pilots

  • Citizen scientist pilots and airplane owners are volunteers — not guided, supported, or paid by NASA.
  • Each pilot is fully responsible for the safe operation of their aircraft. Mounting system hardware for their imaging system by following air-frame manufacturing or FAA guidelines and regulations.
  • Pilots are free to choose their own flight paths and flight plans.
  • NASA or the project shall not pay for any pilot services, such as aircraft maintenance, hangar rent, or fuel.

General aviation (GA) pilots functioning as citizen scientists can help develop an early warning system to alert communities of ensuing algal bloom along the coastline.

Private GA Pilots

There are 600,000 private pilots in the U.S. and over 200,000 general aviation (GA) aircraft. A fraction of this untapped resource can be used to study water quality scientific issues in aquatic systems.

Citizen Science

Scientific research conducted, in whole or in part, by amateur or nonprofessional scientists. This may include crowd-sourced science, community engaged science, or networked science.

A Global Problem

Algae blooms pose serious problems to human health, fish, and recreation industry. The economic damage to commercial fishing is $100 million and rising due to climate change (NOAA).

How to Get Involved

Pilots

  • Obtain high resolution aerial images and videos
  • Fly over potentially impacted waterways

Researchers

  • Study plume and sedimentation dynamics, harmful algal blooms (HABs) initiation and distribution, algal mat structures, and Langmuir circulation and identify “hot” areas of concern.
  • Make data publicly available to students, teachers, researchers, water-quality managers, and policy makers.
  • Help develop empirical scientific models leading to next steps in predicting a HAB event.

Teachers

  • Use the photos and results to educate in water quality issues and the dangers of harmful algal bloom outbreaks to human health
  • Ask students to come up with innovative solutions for the future

Students

  • Use simple cell phone cameras in your area, if safely possible, to shoot and compare their photos with aerial data

Members of the Public

  • Help generate awareness of your environment

What’s New

Off-the-shelf cameras now have built-in GPS so accurate geo-referencing is easier.
