From discovering new fish to mapping the ocean floor, women scientists have done amazing things for our oceans. This International Women's Day, let's dive into the stories of ten women who made big waves in ocean science. Join us in celebrating their work and the discoveries they have shared with the world.

The UK government just announced plans to increase marine protection around South Georgia and the South Sandwich Islands. When Lewis pioneered his swim in SGSSI in 2017, only 2% of this crucial biodiversity hotspot had full protection. In the year following the swim, the government increased protection to 23%. The recent announcement of a further 166,000km² – an area of water larger than England and Wales combined – will bring the level of protection to 36%.

In his new series 'SINK / RISE', fine art photographer, Nick Brandt, offers a chilling underwater immersion into the lives of South Pacific Islanders.

From seahorse couples who come together in the morning to dance, to male pufferfish who attract mates by creating intricate sand sculptures, the ocean is brimming with examples of creativity, devotion and endearment.

We’ve been all over the news since Lewis successfully completed his 315-mile swim down the Hudson River. In case you missed some of the stories, you can relive the swim and catch up with the reactions during and after right here.

The Hudson Swim began at Lake Tear of the Clouds, and finished in Manhattan one month later. We documented each day of the Hudson Swim so you could follow along live. Now you can relive this unforgettable journey with us.

Monday 4 September was a special day for the Foundation, as Lewis and the swim team were welcomed into Lenape territory by Chief Vincent Mann and members of the Lenape Ramapough Turtle Clan. The Lenape are the original inhabitants of much of what is now New York, New Jersey and Pennsylvania and Delaware, including all of the Lower Hudson Valley.

Rivers are lifelines for millions of people, animals and ecosystems – and all of them ultimately lead to the ocean. We cannot protect our oceans without protecting rivers. Which is why we are celebrating these brave River Warriors who dedicate themselves to recognising, protecting and defending our precious river systems.

What is the first thing that comes to mind when you think about the high seas? Endless blue horizons, unimaginable depths, and elusive creatures like the blue whale – or pirates, plunder and lawlessness? All of these would be accurate, but hopefully that last part is about to change.
