Alaska Expedition Team

Your Seabourn Expedition Team is a select group of academics, scientists and general naturalists who share your passion for exploring the world's remote regions. They guide your off-ship expeditions, and provide expert insights into the bio-diversity, ecosystems, physical science, history and culture of your destinations, both in formal Seabourn Conversations presentations and casual discussions.

Expedition Team Members

Seán Bercaw | Expedition Leader

By the age of thirteen, Seán had already spent a quarter of his life sailing around the world with his mother, father, and two sisters on a 38-foot ketch.  He joined Seabourn’s Expedition Teams in 2019 and began working as an Expedition Leader in 2022.

As a young lad, Seán began the tradition of launching messages in bottles on the high seas. To date, he has set over 300 bottles adrift and has received more than sixty responses. Whatever role he plays on the water, Seán remains steadfast to two missions: to connect people with the sea and to connect with people through the sea.

Seán Bercaw | Expedition Leader

By the age of thirteen, Seán had already spent a quarter of his life sailing around the world with his mother, father, and two sisters on a 38-foot ketch. The 3½-year circumnavigation encompassed 37,404 miles and 248 ports-of-call in 28 countries. From that sailing foundation, Seán studied Civil Engineering at Northwestern University. Commissioned as a U.S. Naval Officer, Seán’s service included training with the Navy SEALs, a deterrence cruise aboard a submarine, and a year overseas in Diego Garcia, Indian Ocean. Upon leaving the Navy, Sean earned a Master’s in Marine Affairs from the University of Rhode Island.

Although he has over 199,000 miles under sail, Seán considers himself a teacher first and sailor second. Teaching courses ranging from Celestial Navigation to Environmental Awareness, he has worked over thirty years as captain and faculty member for a university sea semester program on journeys throughout the Atlantic and Pacific oceans. In addition to these oceanographic tall ship voyages, Seán was instrumental in captaining the Freedom Schooner Amistad into Havana, Cuba, in 2010, fulfilling the vessel’s ambassadorial mission.

Seán continues to explore new venues in the maritime environmental world. Scientific forays include working as the ROV navigator aboard the E/V Nautilus for deep ocean exploration and as the Marine Projects Coordinator aboard the two U.S. Antarctic Program Research Vessels. In that role, he facilitated numerous research expeditions to Antarctica. Seán joined Seabourn’s Expedition Teams in 2019 and began working as an Expedition Leader in 2022.

As a young lad, Seán began the tradition of launching messages in bottles on the high seas. To date, he has set over 300 bottles adrift and has received more than sixty responses. He has corresponded with bottle-finders from ages seven to seventy on five different continents. Whatever role he plays on the water, Seán remains steadfast to two missions: to connect people with the sea and to connect with people through the sea.

Dexter grew up in England where a love for exploring the pastoral countryside of East Anglia ignited a lifelong passion for discovering natural history and embarking on adventure. His International travel started early with trips to India which sparked a deep fascination with the insect realm and a desire to share a “hidden” macro world ignited. He developed a popular insect website and delved into how humans relate to the natural world.

Moving to the United States in 1982, his first multimedia production, entitled Pure Muir Madness, employed a bank of projectors to document a 230-mile backpack through the Sierra Nevada Mountains. It was at that point, Dexter discovered the power of a well-crafted production to move and motivate an audience.

After graduating from UC Davis with a focus on computer graphic design, Dexter has enjoyed over 30 years of creative media collaborations with a broad spectrum of projects and clients in print, web and photography.

For many years, his travel was insect-inspired, traveling to lush rainforests of South America and Indonesia but slowly this morphed into more adventure-inspired trips to Nepal, Peru and extensively in the Western US.  During downtime, he is most at home exploring Southern Utah’s geological wonders.

Ten years ago, Dexter discovered a perfect career fit within the blossoming expedition travel industry and since has travelled worldwide filming and producing over 150 films from The Arctic to Antarctica and many choice locations between.

Finding and sharing the absolute beauty of the natural world is his unquenchable passion.
