Oceanites We are the world’s only publicly-supported nonprofit research program monitoring the vastly warmed Antarctica peninsula. year-round and by 5˚C./9˚F.

Oceanites is a US-based, nonprofit, scientific, and educational organization, founded by Ron Naveen in 1987 (https://oceanites.org). Its mission is to advance science-based conservation and to increase the awareness of climate change, its potential impacts, and climate change adaptation through the lens of Antarctic penguins. Since 1994, Oceanites’ Antarctic Site Inventory (ASI) has monitored and analyzed penguin and seabird population changes across the vastly warmed Antarctic Peninsula. Significantly, the ASI is the only nongovernmental, publicly supported, scientific research project working in Antarctica — and the only project monitoring penguin population changes across the entirety of the Antarctic Peninsula. In that region, it’s warming as fast as anywhere else on Earth (over the last 60 years, by 3˚C./5˚F. in the austral winter). Since 2016, Oceanites has maintained the Antarctic continent-wide penguin population database known as MAPPPD (http://www.penguinmap.com). This database is an open access decision support tool that assembles Antarctic penguin population data and makes the data free and accessible to the public. The MAPPPD database is continually being updated and is utilized by Oceanites to generate its State of Antarctic Penguins reports, which comprehensively summarize the ongoing status — population size and population trends — of Antarctica’s five penguin species. Regarding policy making in Antarctica, Ron Naveen has served as an adviser on the U.S. Delegation to the Antarctic Treaty Meetings and, for the last seven years, Oceanites has been an invited, international expert observer to meetings of the Commission for the Conservation of Antarctic Marine Living Resources, which manages fishing of Antarctic krill and toothfish. Oceanites also focuses its efforts to promote education and outreach by providing the best available scientific information into the hands of everyone. The reality is that Oceanites’ study penguins are the ‘canaries in the coal mine’ who remind us that we are all biological creatures. Just like penguins, our human future also depends on The 4 Vitals — whether and how we can adapt and still have a safe homes, food to eat, good health, and continue to produce children for generations to come.

One month from today, our 2026/27 field season begins.

Every season starts long before anyone steps ashore. There are berths to secure on partner ships, gear to ready for the Peninsula, training to finish, and hours of data work that turn a day in the colonies into numbers the world can use.

This season, our scientists will join 16 voyages to the Antarctic Peninsula aboard seven expedition ships. A season like this needs people behind it.

Between now and the 13th of November, we're counting down together. Help put a counter on the ice, and follow along as the season takes shape.

Introducing Stories from the Field 🐧

Every number in our penguin database starts with a person in a colony, counting nest by nest and seeing moments that never make it into a spreadsheet. This new series shares those moments in our scientists’ own words, and each story comes from a colony you can adopt.

First up: Ashley Noseworthy on Half Moon Island, where her first visit came with a rumour about a macaroni penguin named Kevin. Turn your sound on to hear how it ends 🔊

Half Moon Island is home to about 1,518 chinstrap nests, counted last season, and Ashley heads back to the Peninsula this December. Adopt Half Moon Island (Kevin’s neighbourhood) at oceanites.org/get-involved

The world’s largest penguin colony has lost its crown 👀

New research from the British Antarctic Survey reveals Zavodovski Island in the South Sandwich Islands has lost more than half a million chinstrap penguins, with occupied nests down 63% since 2011. The cause is a warming ocean: chinstraps rely on krill, and as waters warm, the krill are shifting south, beyond where these penguins can follow.

The South Sandwich Islands hold about 30% of the world’s chinstraps, and these losses mirror declines on the Antarctic Peninsula. Together, they could push the species toward Endangered status.

Long term monitoring is how we catch changes like this early. Explore chinstrap trends across the Peninsula in MAPPPD through the link below 👇

Here's what one Antarctic season looks like on paper 📝

From early November 2025 to the end of February 2026, 21 counters made 18 trips to the Antarctic Peninsula aboard 7 expedition ships. Nest by nest, they brought back fresh counts from 50+ unique sites, making it a record season.

Every one of those numbers is now open to anyone through MAPPPD.

This season, we go again. Help us get there by donating at the link below👇

Before Oceanites, there was a lecturer and expedition leader who fell in love with a continent.

Ron Naveen spent years guiding travellers across Antarctica. He noticed how little had been written down about the places they visited: which penguins and seabirds lived at each landing site, and how those colonies were doing. So he started Oceanites to give something back.

About five years later, that idea became the Antarctic Site Inventory. Almost four decades on, we're still counting penguins, colony by colony, and sharing the data openly with the world.

"It's just an amazing feeling to know that we are helping conserve this continent for future generations."

Happy World Animal Day from the bottom of the world.

Today we're celebrating the three penguins at the heart of our work on the Antarctic Peninsula: the gentoo, the Adélie and the chinstrap. Each one lives a little differently, and each one tells us something different about how this part of the world is changing.

That's why we count them colony by colony, season after season, and share everything we learn openly. Every penguin counts.

Big news in the penguin world: scientists have described the first new penguin species in more than a century, and it's a gentoo 🐧

Genome sequencing revealed the gentoo is actually four distinct species. The newly named southeastern gentoo lives on the remote Kerguelen Islands, while the gentoos of the Antarctic Peninsula now have a name of their own: Pygoscelis ellsworthi, the southern gentoo. It's the only one of the four found in Antarctica, and projections suggest it may hold steady or even expand its range. That echoes what years of counts on the Peninsula have shown, with gentoos expanding as Adélies and chinstraps decline.

Same island, two very different stories.

On Petermann Island last season, our counters recorded 4,726 gentoo nests and around 170 Adélie nests. The two species share a coastline, but they're telling us very different things about how the Peninsula is changing.

That's why we count colony by colony. When you roll every count into one regional average, the colonies that need attention most can quietly disappear from view.

Our Antarctic Site Inventory captures that detail season after season. We share it openly through MAPPPD, so scientists and policymakers can see exactly what is changing, and where.

Happy World Tourism Day from the Antarctic Peninsula.

Few places on Earth leave a mark on travellers the way Antarctica does, and the best journeys leave the lightest mark on Antarctica. Tourism done responsibly can do something remarkable here: it can carry science to the ice.

For decades, expedition operators have given our penguin counters a berth, a seat in the Zodiac and time ashore at the colonies. That's how we reach sites across the Peninsula season after season, and how our open data keeps growing. Their guests get something special in return: a front row seat to field science, and a deeper understanding of the wildlife they came to see.

Thank you to Aurora Expeditions, Viking, Poseidon Expeditions, HX Expeditions, Polar Latitudes Expeditions and every crew that makes room for science on board. Our mission would not be possible without you.

If you are heading south this season, choose an operator that supports the science, follow the wildlife guidelines ashore, and keep an eye out for our counters.

Meet Steve Forrest, a member of our Board of Directors and one of the people who built the count from the ground up.

Steve is a biologist, conservationist and attorney from Truckee, California. He was a founding researcher with our Antarctic Site Inventory, and this season marks his 27th in the field.

Over those decades, Steve has coauthored numerous published studies on penguin populations and climate impacts across the Antarctic Peninsula, helping turn nest counts into evidence the world can use.

His conservation work reaches far beyond Antarctica. He has worked with WWF and Defenders of Wildlife, and he continues to champion species recovery in North America, including the reintroduction of the endangered black-footed ferret.

From penguin colonies to prairie burrows, Steve's career shows what lasting conservation takes: showing up, season after season. Thank you, Steve, for 26 of them!
