Cairnbase
Institutional memory for expedition operations

For two hundred years, expeditions left cairns so the next party would know the way.
Cairnbase is where your company leaves them now.

Every landing site, anchorage, route, and hard-won lesson: read in from the documents you already have, kept on one map by region, carried offline into the Zodiac. Logged by guides, vetted by expedition leaders, owned by the company.

When an experienced expedition leader leaves, their knowledge leaves with them

Where an anchorage holds in a southerly, which route to the viewpoint avoids the crevasse field, what to say in the Zodiac when the whales show up: that knowledge lives in personal notebooks and private GPX archives today. It leaves with every retirement, every transfer, every season, and the company rebuilds it from scratch each time.

Guides log it from the field: a track, a photo, a note like “downed tree on the overlook trail,” filed in minutes. Expedition leaders vet it: accept what belongs in the company record, star the route, resolve the hazard when it clears. The company keeps it: attributed, dated, permanent. It belongs to you, and it grows with every voyage.

For expedition companies

The knowledge already exists: in site guides, post-voyage reports, GPX archives, and the heads of people who leave. Cairnbase reads it in, files it by region, and keeps it. Built by working expedition leaders.

The import desk

Drop a site guide, a post-voyage report, a spreadsheet. Cairnbase reads it and shows you what it found: sites, visits, hazards, routes, facts. Nothing enters your catalogue until a person confirms it. You see the cost before anything is read.

The catalogue on a map

Every site your company knows, with its visits, hazards, documents, and routes, filed by region. From a hemisphere down to a single beach.

Offline map regions

Government-survey basemaps and terrain for the Antarctic Peninsula, Svalbard, Southeast Alaska, Greenland, and South Georgia. Download a region in port; use it in a Zodiac with no signal.

Your data comes back out

One-click export of the whole workspace: every record, every original file byte for byte, checksummed. No lock-in: leave any time and take everything with you.

GPX straight onto the map

Drag a season of tracks in. One review card, one button, and a landing becomes a site with its visit, never a duplicate.

Accounts and sign-in

Every person who uses Cairnbase signs in with a secure emailed link, no password required. Guides and expedition leaders each have their own account and role, and every record sits behind that sign-in.

Your roster, in minutes

Drop the guide spreadsheet you already keep: returning guides reconnect, new ones are added ready to invite, and access ends by itself on the contract end date you set.

Company workspaces are walled off from each other, and companies keep everything contributed to theirs. The terms say in writing that we never grade or correct your documentation, and how your data is handled is set out in full on the data handling page.

For guides

Most guides are independent contractors, and most of what a company knows came from guides. Cairnbase is built on one rule: what you record is yours.

Your logbook

One entry per outing: where, what you did, your tracks and photos and observations, in your own record, not a company's form.

The region in your pocket

The same offline maps your company uses: survey basemaps, terrain, contours, protected-area boundaries, working with no signal.

Your records are yours

Partly live

Your own account is live now, and everything you log starts there, not in a company's form. Sharing it up to the company you work for, keeping the original forever, and carrying it to your next operator are the next pieces. We never restrict your own tracks; that rule is written into the terms.

Field capture

On the way

Hit record for a landing or a Zodiac leg, pocket the phone, drop waypoints and photos, and sync when the ship finds wifi. A native app for iPhone and Android, built for exactly this.

Your service record

On the way

Seasons verified by the companies you worked for on Cairnbase, plus what you log yourself: a record of your guiding experience that belongs to you.

Five regions, mapped from the survey up

These are not web tiles. Each region is built from the national survey that mapped it, with the layers a field team actually needs, and they work with the phone in airplane mode.

RegionPack contents
Antarctic Peninsula SCAR/BAS basemap with protected-area boundaries you can tap, 39 historic sites, and 65 research stations, present and closed. REMA 32-metre terrain with hillshade and 50-metre contours.

Greenland Four coastal regions on the Danish GL50 survey: Disko Bay and Ilulissat; Scoresby Sund and the park fjords; the Southeast coast to Tasiilaq; Kap Farvel to Nuuk. Coastline-following boundaries, checked for holes.
South Georgia Survey terrain and basemap for the whole island, from Salisbury Plain to Cooper Bay.

There is nothing to log into yet. What exists is a list: expedition operations who want first sight of Cairnbase, and a say in what gets built while it is still cheap to change. Pilots begin with the 2026-27 season.

If Cairnbase turns out to be the wrong tool for your operation, we will tell you that too. There is no confirmation email, because the site sends none: the list is read by hand.

Your address goes into our own database, is used to reply and to tell you when pilots open, and goes nowhere else. Detail in the privacy policy.
