Good to know

No. The certificate is a symbolic gift. Ice in the Southern Ocean falls under the Antarctic Treaty and no private person can own it. You are buying a keepsake document and a place in our register, not a property title.

It's an unusual, symbolic gift for Christmas, a birthday or a new baby: a real iceberg, a certificate in the recipient's name and, if they wish, news every year. Choose the gift option and a sending date: the certificate is emailed to them on that day. Nothing to make or ship.

Icebergs are visible witnesses of melting ice. The site shows public sea ice measurements, offers a contribution to Stripe Climate for carbon removal, and sends yearly news about the ice.

For an Antarctic iceberg, every year we use the latest public report from the U.S. National Ice Center: position and size, or notice that it is no longer tracked because it melted or broke up. For an Iceberg Alley iceberg, whose data are archives, the email shows the state of Arctic sea ice measured by NSIDC. It is free and you can unsubscribe at any time.

Choose “It's a gift”, enter the recipient's name, your name and, if you like, their email and a sending date. The certificate says “A gift from”.

It melts; that is its nature. The certificate stays valid as a keepsake. With the ownership page, the listing shows the melt date and the last known position.

Yes. An iceberg can have several symbolic owners, each with their own registration number.

From U.S. public agencies: the U.S. National Ice Center for Antarctic icebergs (latest published report) and NOAA/NSIDC for the International Ice Patrol archives and sea ice extent. These data are public and free to reuse; we cite their source. Coastlines come from Natural Earth, in the public domain.

It is the corridor through the Labrador Sea and the Grand Banks of Newfoundland that hundreds of icebergs from Greenland drift down every spring. The International Ice Patrol, set up after the Titanic sank, records every sighting. The icebergs in this collection come from its 2021 season archives: they have since melted, and the certificate retraces their journey.

For each Antarctic iceberg we looked for a public NASA satellite image taken around the report date. When the iceberg is clearly visible and the area measured on the image matches the USNIC figure, its real outline is used (marked “Real outline”). Otherwise the outline is estimated from its length and width. Iceberg Alley icebergs have no public photo or outline: only their shape category is known.

Stripe Climate is a programme run by Stripe, our payment provider, that funds permanent CO₂ removal projects selected with scientific experts. If you tick the box in the cart, 5% of your certificates' amount is added to your order on a separate line and passed on in full to Stripe Climate. Learn more: stripe.com/climate.
