The trip began in Punta Arenas, the capital of Magallanes region, Chile. We had spent three days aboard the Arctic Sunrise, a Greenpeace ship docked in one of the city's harbours, to test our equipment and conduct security drills. I was eager to get to Antarctica.
Greenpeace, the global environmental group, organised the journey to raise awareness of, and support for, a European Union proposal to create the biggest protected area on Earth in Antarctica. The plan was to create a safe haven for marine life there from industrial fishing.
The strategy involved documenting the effects of climate change, pollution and fishing on native wildlife. Pictures and video footage, specimen samples from the Antarctic seafloor, and surface water sampling for microplastics were all collected by Greenpeace to help build the case for the sanctuary.
The proposed Weddell Sea Marine Protected Area (MPA) would cover some 1.8 million sq km (1.1 million square miles) of natural habitat for whales, seals, penguins and many kinds of fish. It will be considered by the Antarctic governance body, the Convention for the Conservation of Antarctic Marine Living Resources, at its October 2018 in Australia.
"Antarctica itself is currently protected under the Antarctic Treaty, but there is a lot of scope for abuse of the waters around Antarctica, and it is already dealing with the issues that are happening elsewhere in the world, such as increasing CO2 levels, acidification of the oceans, and plastics," said Tom Foreman, a Greenpeace expedition leader.
"So, the chance to protect these areas, which are so vital to such a huge number of species in so many ways, it can't really be missed," he said.
According to Greenpeace, a key concern is industrial fishing for krill. The group issued a report this month noting that most Antarctic wildlife, including penguins, whales and seals, depend either directly or indirectly on the small shrimp-like creatures for food. Humans use krill in Omega-3 tablets and in pet food.
"We are asking all krill fishing vessels not to fish in any area in the Antarctic being proposed for protection," said Luke Massey, a spokesman for Greenpeace.
When the ship finally left port, I realized how much I enjoyed the feeling of being at sea. It provides a sense of freedom and promise for the future, the kind you get when you start a new relationship, a new job, or a trip to somewhere that you've never been.
After rounding Chile's Tierra del Fuego, escorted by dolphins that reminded me of dogs chasing a car, we reached a spot I had studied in college Geography classes: the fabled Drake Passage, the point where the Atlantic and the Pacific Oceans violently collide off the southern headland of South America.
We had been informed the passage could be rough, so we started tying everything down. Pills for seasickness were handed out and the bathroom lights were left on to accommodate those who handled the ride poorly. I decided not to take the pills. That was a mistake.
It felt like being in a centrifuge. After the first few hours of the passage, I went to the bridge to ask the captain how many more hours it would take to get to calmer waters. "It can be up to four days," he said. He reminded me we were in an icebreaker, a solidly built ship, but not designed for a smooth, swift ride. These were possibly the longest four days of my life.
When we arrived at the Antarctic Peninsula, the ocean was again calm, and we could spot lots of wildlife. Contrary to what some may think, the Antarctic is full of life. Penguins, seabirds, and different species of seals and whales could be seen at all times.
We went ashore on rubber boats, wearing survival suits weighing nearly 10 kilograms (22 pounds). I packed an extra camera and a couple of long lenses, too, adding even more weight to the already uncomfortable suit. It would be worth it. I could not afford to waste a rare chance at a good Antarctic photo due to a camera malfunction in a distant penguin colony.
My encounters with the penguins were wonderful and joined my list of unforgettable moments. They do not see humans as predators and can surround you for hours if you do not move much. Along with my dog, I think they are the sweetest things in this world. On these trips ashore, I generally had a couple of hours to shoot pictures. On every one of them I felt like a child in a candy store.
I made it onto a helicopter after several days, when the weather became clear enough for safe flight. During three trips over the peninsula, I saw some of the most splendid landscapes I had ever seen. None of my pictures do justice to the experience of seeing these places first hand.
As my long trip proved, Antarctica is remote from civilization. But it is not untouched. Greenpeace came here to point out some of the region's vulnerabilities. I hope my pictures reveal some of the region's beauty.
