Reposted from IOOS Association - Senate & House Oceans Caucus Leaders Introduce Bipartisan Resolution Recognizing World Oceans Day.

IOOS Association Executive Director, Kristen Yarincik shares her thoughts on this special acknowledgment. “We applaud Congress for recognizing World Oceans Day and celebrating the maritime heritage that has shaped our nation for more than 250 years. This recognition highlights the vital role of ocean observations and the information services they support in helping fishermen, mariners, ports, businesses, and coastal communities make informed decisions that strengthen maritime commerce, support seafood production, enhance public safety, and help sustain America’s ocean economy for future generations.”

In celebration of World Ocean Month and World Oceans Day, the 11 IOOS Regional Associations unite for Ocean Data Day on June 25th. Learn more about how you can raise awareness of ocean, coastal, and Great Lakes data: https://ioosassociation.org/oceandataday/

Ocean observing data helps keep maritime commerce moving safely and efficiently. Real-time information on winds, waves, currents, and weather supports cargo ship navigation, port operations, and supply chains that are critical to the economy.

Happy World Oceans Day! In celebration, the IOOS Regional Associations unite in bringing us the second annual Ocean Data Day on June 25.

Every day, ocean and coastal observing systems provide real-time information that helps industries operate safely, supports research, informs forecasts, and strengthens coastal economies.

This year’s Ocean Data Day theme, 𝘾𝙤𝙖𝙨𝙩𝙖𝙡 𝘿𝙖𝙩𝙖 𝙛𝙤𝙧 𝙖 𝙎𝙩𝙧𝙤𝙣𝙜 𝙀𝙘𝙤𝙣𝙤𝙢𝙮, is a reminder that ocean data powers decisions far beyond the water.

Sargassum Outlook for Puerto Rico & the U.S. Virgin Islands

The latest 7-Day CARICOOS Sargassum Inundation Forecast indicates the highest potential for sargassum accumulation along Puerto Rico's south and southeast coasts, with additional impacts possible in Vieques and parts of the U.S. Virgin Islands. Lower accumulations are expected along most northern coastal areas.

This forecast estimates how much sargassum, measured in kilograms per meter of shoreline, may reach the coast during the coming week, helping coastal communities, beach managers, boaters, and visitors stay informed and prepared.

El más reciente Pronóstico de Inundación de Sargazo de CARICOOS para los próximos 7 días indica el mayor potencial de acumulación de sargazo a lo largo de las costas sur y sureste de Puerto Rico, con impactos adicionales posibles en Vieques y partes de las Islas Vírgenes de los Estados Unidos. Se esperan acumulaciones menores en la mayor parte de las costas del norte.

Este pronóstico estima la cantidad de sargazo, medida en kilogramos por metro de costa, que podría llegar al litoral durante la próxima semana, ayudando a comunidades costeras, administradores de playas, navegantes y visitantes a mantenerse informados y preparados.

It’s and Friday!
Bivalve aquaculture is helping to boost U.S. coastal economies. Yet the industry remains vulnerable to ocean acidification, which can impact its product across life stages, especially at the larval stage.

In a recent study, scientists found that maternal signaling in Manila clams boosts larval resilience under more acidic conditions.

Plans for this weekend? Warmer conditions, along with concentrations of Saharan Dust are expected through Monday. Stay hydrated and follow medical recommendations.

¿Tienes planes para este fin de semana? Se esperan condiciones calientes junto a concentraciones de polvo del Sáhara hasta el lunes. Manténgase hidratado y siga las recomendaciones médicas.

Happy World Ocean Month! In celebration of this month, IOOS Ocean Data Day returns on June 25, 2026. Our theme this year is 𝘾𝙤𝙖𝙨𝙩𝙖𝙡 𝘿𝙖𝙩𝙖 𝙛𝙤𝙧 𝙖 𝙎𝙩𝙧𝙤𝙣𝙜 𝙀𝙘𝙤𝙣𝙤𝙢𝙮 highlighting how ocean, coastal, and Great Lakes data support maritime transportation, fisheries, tourism, public safety, research, and coastal communities across the country.

Throughout June, we’ll be sharing ways you can explore, use, and elevate coastal data in your own work and community.

Outlook of 2026 Sargassum blooms May 31, 2026 by the University of South Florida Optical Oceanography Lab
Looking ahead: Sargassum amount in most regions is likely to increase in June. Beaching events around the Caribbean and southeast coast of Florida will continue and likely increase. Some beaching events may also occur around Louisiana and Texas coasts. The year of 2026 is set to be another major Sargassum year (i.e., Sargassum amount exceeds 75% of the historical values), and possibly to be a record year by summer 2026.

The CARICOOS Aerosol Monitoring Tool provides satellite-based observations and forecasts of Saharan Dust and other airborne particles affecting Puerto Rico, the U.S. Virgin Islands, and the wider Caribbean. The tool shows current aerosol conditions, short-term forecasts, and maps that help users understand when dust concentrations are increasing.
A key value shown is AOD, or Aerosol Optical Depth, which indicates how much dust or particles are present in the atmosphere. Higher AOD values usually mean hazier skies, reduced visibility, and a greater chance of allergy or respiratory discomfort, especially for sensitive groups. Users can check conditions by location and monitor changes over the next 24 to 48 hours at: https://aerosols.caricoos.org/

La Herramienta de Monitoreo de Aerosoles de CARICOOS ofrece observaciones y pronósticos basados en satélites sobre el polvo del Sahara y otras partículas en el aire que afectan a Puerto Rico, las Islas Vírgenes Estadounidenses y el Caribe. La herramienta muestra las condiciones actuales de aerosoles, pronósticos a corto plazo y mapas que ayudan a identificar cuándo aumentan las concentraciones de polvo.
Un valor clave que presenta es el AOD, o Profundidad Óptica de Aerosoles, que indica cuántas partículas o polvo hay en la atmósfera. Valores más altos de AOD generalmente significan cielos más brumosos, reducción en la visibilidad y mayor posibilidad de molestias por alergias o condiciones respiratorias, especialmente en personas sensibles. Puede monitorear las condiciones por ubicación y los cambios esperados durante las próximas 24 a 48 horas en: https://aerosols.caricoos.org/
