Today is UN World Oceans Day! This year's theme, "Awaken New Depths," invites us to explore the vast mysteries of our oceans. There's so much we have yet to discover about the underwater world and its incredible life forms. In just 23 days, we'll embark on our voyage across the oceans.
The eureka moment that turned our 20-year dream of a sailing journey into reality happened while I was volunteering as a conservation diver in Nosy Komba, Madagascar. One day, as I was mapping beautiful corals, fish, and nudibranchs, I spotted a solitary sailboat anchored in a stunning bay. Inspired, I called Espen, and our plan started to come alive.
Another unforgettable experience in Nosy Komba was discovering my new hero, Sylvia Earle. Other passionate volunteers introduced me to her books and work, and I was captivated. Sylvia Earle is an American oceanographer and explorer renowned for her research on marine algae and her efforts to raise awareness about the threats of overfishing and pollution. She is a pioneer in using modern SCUBA gear and developing deep-sea submersibles in her research.
Learning about Sylvia Earle and observing the magnificent creatures on the healthy coral reef every day ignited my passion like never before and I now have a deep care for the ocean.
It is therefore so sad to read the new UNESCO State of the Ocean Report. The report reveals alarming threats to the oceans. Climate change is having a major impact, causing rising temperatures, increased acidification, and higher sea levels.
Unlike fluctuating atmospheric temperatures, the ocean is steadily warming, now twice as fast as it did 20 years ago, with 2023 seeing one of the biggest increases since the 1950s.
Since the 1960s, the ocean has lost 2% of its oxygen due to warming and pollution from wastewater and agricultural runoff. Coastal areas are especially hit hard, with around 500 "dead zones" where almost no marine life can survive due to low oxygen levels.

The fjord next to our home, Oslofjorden, is in trouble. Emilie and Christoffer began their diving course this week and will complete it on Sunday. It's heartbreaking to think they might not see any sea life during their four dives in the fjord this weekend. Fishing is now banned in the fjord, and efforts are underway to reduce agricultural runoff and pollution. I hope that by the time we return, the Oslofjord's condition will have significantly improved.

The ocean is absorbing a lot of carbon, which is expected to more than double ocean acidification by the end of the century. To tackle this, we need both national and local actions tailored to each region's needs.
The UN is teaming up with leaders, scientists, businesses, civil society, celebrities, and youth activists to highlight the urgent need to change our relationship with the ocean. Our past efforts have barely scratched the surface and inspire widespread action, UN says we need to "awaken new depths."
It's important to remember that Indigenous peoples have been using and conserving the ocean for centuries. Their knowledge, from the Arctic to the tropics, is vital for maintaining the balance between nature and humanity.
Our journey hasn't begun yet, but this week, we're applying a silicon-based anti-fouling coating to the boat. Traditional anti-fouling paints prevent fouling by continuously releasing copper and other toxic substances that are harmful to marine life. In contrast, silicone paints rely on their smooth surface properties to prevent organisms from sticking to the hull. Silicone paint is derived from silicone oxide, which is extracted from sand. Ecotoxicological studies show that silicone paints are significantly less harmful to the environment compared to copper-based paints. Additionally, we've decided to use an electric outboard motor, although we're concerned the kids might find it slower and less exciting.
We are committed to taking action and helping to "awaken new depths." By raising awareness, supporting conservation efforts, and collaborating with local and global communities, we aim to protect and restore our oceans, we will promote and adopt sustainable fishing and boating practices, advocate for ocean equity, and we hope we will be able to learn from and work with Indigenous peoples along our way.
