15 minutes

Isla Caroline, ChileLink
15 minutes. That was how long we had sunny, calm weather.

We had started out towards the open waters of the ocean side of Isla Caroline, before the winds and hail forced us to turn back. A narrow passage through the island was our last option to get to the open ocean facing side of Caroline. About an hour later we were finally there, and the small islands covered in tussock grass looked ideal for southern rockhopper penguins.



Unfortunately, the weather continued to be uncooperative and we were not able to make any landings. We stood on deck with binoculars searching for signs of rockhopper colonies, but nothing definite was seen. Rockhopper penguins were reported in these waters almost 100 years ago by explorers taking refuge at Isla Caroline from a storm at Isla Ildefonso.

Could it be that the southern rockhopper penguin has died out or left this area of Chile? Our boat crew tells us that over the years there has been heavy fishing in this area, an insight that may explain the absence of penguins around Isla Caroline. Over fishing is a major problem facing all species of penguins and has taken a serious toll on their overall population numbers.

The weather starts to turn again and we must leave the exposed, open ocean side of Isla Caroline. Today is the last day for us to search for rockhoppers and we must make our way back to port in Punta Arenas. Although we are disappointed that we were not able to visit all the islands and explore as many penguin colonies we had hoped, such is the nature of working in the field. The wind and rain do not always cooperate, and sometimes the snow and hail make matter worse.

You may get 15 minutes of beautiful sunshine, and then spend the rest of the day shrouded in fog. The only thing you can do is use every moment available to explore and learn about the environment around you, whether it be the penguins you came thousands of miles to study or the gulls nesting right outside of town.

40 degrees

Isla Waterman, Chile

Crossing through the open seas are difficult. This morning we left Isla Waterman and tried to reach Isla Caroline through the open ocean waters. Huge swells rocked the boat side to side and back and forth. I watched the pendulum of the gauge that measures the angle of boat pitch swing past 40 degrees! Eventually we had to turn back and instead tried to reach the ocean side of Isla Caroline by first crossing through the narrow channel that ran behind it. Along the way we looked for any signs of southern rockhopper penguins.





Some of the smaller islands surrounding the back of Isla Caroline had similar characteristics to Isla Terhalten and Sesambre--tall, jagged cliffs topped with dense tussock grass, and the open ocean access rockhoppers seem to prefer. As the failing weather would not allow any landings on these islands for further investigation, the best we could do was scan the islands and water with binoculars, but no rockhoppers were seen. Hugo found a small cove for the Chonos to anchor in for the night. Tomorrow we will have one last chance to reach and explore the ocean-facing side of Isla Caroline.

A lot of time for solitaire

Isla Gordon, Chile

This morning we were relieved to wake up to the beeps and grumbling of the Chonos's engine starting. The winds had finally calmed and the harbor master had given the okay for boats to leave Puerto Williams.



Today we were able to make it through to the southern branch of the Beagle channel before another storm again forced us into hiding. The protected cove on Isla Gordon that will be our home for the night is surrounded by waterfalls and across the entrance of the channel you can just make out a glacier through the rainy darkness.


Our hopes of making Isla Caroline in the near future are fading. As frustrating as this waiting can be it is the nature of research in the beautiful, harsh and unpredictable fjords of southern Chile.
