World Oceans Day 2023
World Oceans Day has fallen on June 8, every year since 1992. It’s a day to honor our connection to Earth’s oceans – even if we don’t live near a beach – and to learn what we can do to protect ocean habitats. Go here to participate in today’s fully virtual World Oceans Day celebration. The virtual event runs from 14 to 17:30 UTC (9 a.m. to 12:30 p.m. CDT).
World Oceans Day 2023 has the theme of Planet Ocean: Tides are Changing.
The day is meant to shed light on the wonder of the ocean and how it’s our life source, supporting humanity and every other organism on Earth.
Here’s a calendar of additional events around the world.
Why Earth’s oceans are so important
Earth’s oceans are critical to human survival. Indeed, more than half the oxygen in our atmosphere is generated via photosynthesis by phytoplankton and seaweed in oceans. In addition, millions of people depend on fish and other marine animals for food. Research in some marine organisms has led to the development of new medications. Moreover, ocean currents, known as global conveyor belts, help regulate Earth’s climate.
Perhaps the best reason we’ve seen to honor and protect Earth’s oceans comes from the 2013 video below, featuring Sylvia Earle, who is a National Geographic Society Explorer-in-Residence and perhaps the world’s most recognized living oceanographer. In the video below, among other things, Earle says:
I think of the ocean as the blue heart of the planet.
In addition, she says:
We, too, are sea creatures.
History of World Oceans Day
Canada made the original proposal for World Oceans Day in 1992 at the Earth Summit in Rio de Janeiro, Brazil. Subsequently, the day was unofficially celebrated on June 8 until 2008, when the United Nations officially recognized it. Since then, The Ocean Project and the World Ocean Network have coordinated World Oceans Day internationally. These organizations say they have had greater success and global participation each year.
We know that human activities have adversely affected the health of oceans: pollution, over-fishing, seawater acidification due to increased carbon dioxide, ocean warming and habitat destruction. There is so much to do to repair the damage.
So, what can you do to help?
There are things you can do on your own, on this day or any other. For example, if you live near an ocean, perhaps join a shoreline cleanup.
Even if you’re not near the sea, you can encourage your seafood retailers and favorite seafood restaurants to source their seafood more sustainably (Monterey Bay Aquarium’s Seafood Watch program is a terrific resource).
And we can all reduce our use of plastics with reusable shopping bags and refillable water bottles, and by using biodegradable products over plastic.

Bottom line: June 8 is World Oceans Day. 2023’s theme is Planet Ocean: Tides are changing.
