Final Symposium Program & Agenda

Local coordination was led by NEIWPCC, New York State Department of Environmental Conservation, and U.S. Geological Survey with support from the U.S. National Office for Harmful Algal Blooms at the Woods Hole Oceanographic Institution.

The symposium theme was “Science to Support Solutions from Shore to Shore. From freshwater to marine systems, the prevalence of harmful algal blooms (HABs) is a national environmental challenge, and solutions are needed. Celebrating this event in New York – the only state with Great Lake shorelines, marine coasts, and the diverse range of ecosystems between these extremes – created an ideal setting to discuss progress in understanding algal bloom ecology and the solutions necessary to prevent and reduce HABs.

The conference was open to all registrants. Attendees included national representatives and researchers from academia; state, federal, tribal, and municipal governments; the private sector; and watershed organizations.

NEIWPCC is committed to providing an event that keeps all participants as safe as possible and promotes the well-being of our community. NEIWPCC requires all individuals who participate in the 11th US Symposium on Harmful Algae to be fully vaccinated in order to attend.

  • Following the U.S. Centers for Disease Control and Prevention’s (CDC’s) guidance, people are considered “fully vaccinated” either 2 weeks after they receive their second dose in a 2-dose series, such as the Pfizer or Moderna vaccines, or 2 weeks after they receive their single-dose vaccine, such as Johnson & Johnson’s Janssen vaccine.
  • As new guidance regarding vaccine recommendations is updated by the CDC to include booster doses in the future, participants may be required to provide proof they have received such doses.

Guests must show proof of vaccination when arriving at the event. Accepted proof of vaccination includes the original vaccination card, a printed copy of the vaccination card, or a digital photograph of the vaccination card. To protect confidential information, NEIWPCC will not maintain copies of these documents, and any records provided will be discarded.

In addition, all attendees must adhere to all 11th US Symposium on Harmful Algae Conference safety measures. The 11th US Symposium on Harmful Algae will operate according to the prevailing federal, state, county, and city laws, regulations, recommendations, and guidelines, as well as venue-specific regulations for the Hilton Albany, as they are in effect over the 11th US Symposium on Harmful Algae dates (including but not limited to face mask requirements, social distancing, etc.).

To ensure safety, we will not be accepting on-site registrations.

We will continue to revise our procedures as needed to reflect the current state of the pandemic.
