Alastair Newton
Alastair grew up sailing everything from dinghies to 50-foot yachts and developed apassion for all things nautical. He came to the United States from England in 1997 for a six month internship at the Large Animal Research Station in Alaska. He returned home with the intent of attending college in London, but after a year of missing Alaska and its incredible wildlife, he packed up and moved back to Alaska to complete his degree.

While living in Anchorage, Alastair taught natural history and general biology at the University of Alaska. He brings to Cruise West a tremendous enthusiasm for biology, wildlife and the great outdoors. Alastair’s special interests include environmental education, hiking, reading and sailing. He is also fascinated with how animals adapt to the challenges of their specific environments.

Alastair recently became a fellow of the Royal Geographic Society. He spends his off time visiting schools in England, giving lectures on life and biology in northern climates. He was also a guest speaker in several English schools during National Science Week. If he could tap the heels of his hiking boots and go anywhere in the world? He'd go to Fairbanks, Alaska.

She has traveled and studied extensively through the wilds of Alaska and is thrilled to share her knowledge and “sense of wonder” with you.



Brad Mason
Some years back, during a walking tour of Juneau, I was leading a group through the streets of downtown, talking about one of the old saloons or something, when all of sudden, about a block ahead of us, a black bear emerged, trotted across the street, and ran between two gift shops up into the hills above town. We all just stood in silence for a few seconds, then a lady in the group asked if that was really a bear we’d all just seen run out in front of us in a state capitol. I replied, “Yes it was.” She said “Ok,” and we all proceeded in the opposite direction towards the old Russian Orthodox church in town.

Originally hailing from Texas, Brad’s passion for travel and love of the outdoors first took shape along the desert trails in the mountains of west Texas. Undoubtedly contributing to this passion were all those Louis L’Amour western novels he read as a kid. After gaining a Recreation, Park, and Tourism Sciences degree from Texas A&M University, Brad loaded up his backpack and headed north to Alaska to help run a small lodge just outside Denali National Park and Preserve. Then he became a Park Service Ranger and later worked with a rafting company on the Nenana River. After his stint in the Interior, Brad headed to Southeast Alaska, where he led rainforest and glacier tours for Cruise West as a land-based guide in Juneau, then on to Katmai National Park and Preserve in Southwest Alaska, where he got to play with the coastal grizzlies and lead tours into the park and to the Valley of 10,000 Smokes.

Leaving Alaska after 2004, Brad moved to Santa Fe, New Mexico, where for a couple of years he led tours to native pueblos, national monuments, and old ruins around the southwest region of the U.S. Most recently he has been living in South America, first in Chile, then in Ecuador, working as an English teacher and trying to explore more and more of that continent. Brad’s excited to be backin Alaska and the Pacific Northwest. When not guiding a tour, Brad is usually attempting to feed his insatiable curiosity of people and places and things of all sorts.




Cal Ulberg
To me your trip is more than what you see or hear; it is a total experience.
Cal joined Cruise West in 2007 bringing a diverse background with him. And so far his experiences at Cruise West include serving as a licensed deckhand in Southeast Alaska, an inflatable excursion craft operator and Exploration Guide in Mexico.

Cal grew up in Seattle, graduating from the University of Washington with a chemistry education major, a physics minor and a master’s degree in education from Seattle Pacific University. Cal spent over two years serving in the Coast Guard teaching at their academy in Connecticut, and sailing the Atlantic Ocean, the Pacific Ocean, and the Bering Sea.

Cal’s other teaching experience includes 14 years at the elementary school level and 10 years teaching high school science and math. He also coached wrestling and soccer. Cal has earned a 100-ton near coastal masters license and has worked in Alaska as a fishing guide, in Hawaii as a deckhand on a snorkel boat and in Seattle as a duck driver.



Chelsea Leven
Chelsea'slove of geology inspired her to get her bachelor’s in geology from Amherst College. Her studies were supplemented with field courses in Hawaii, New Zealand and Montana. Chelsea participated in a geological survey in the Nez Perce National Forest of north-central Idaho, a paleoclimate and ecology study into the Atacama Desert of northern Chile, and on a spotted owl and northern goshawk observational study into Yosemite National Park. She also went on a scuba-based field study of tilefish in Cozumel, Mexico.

Chelsea has done volunteer work at a wildlife rehabilitation center in a tiny Costa Rican village in the rainforest, and in Sri Lanka following the tsunami. She is ready to share her love of geology, the formation, composition, and rock movement as well as exploring how geology can affect so much of our lives – breathtaking landscapes, wildlife and plant distributions, population movements and the history and legends of local peoples. When she’s not working, Chelsea likes to ski and snowboard, go caving, kayak, read, paint, draw, photograph, SCUBA dive, sail, backpack, bike…as you can see basically anything to be outside.

What’s one thing Chelsea never leaves home without? Her appetite for adventure and learning.



Copper Bittner
I was assigned to Prince William Sound. I knew what glaciers were, of course - I had studied them, read everything I could get a hold of as background material. But when I got to the Sound, and we sat in front of Harvard Glacier, the rifle-shot cracking and thunderous bellows of ice calving into the sea sent me into a state of shock. Here was a 300-foot high, mile-wide moving river of ice, always forming, always calving right off the bow of our tiny ship!

Copperhas been studying the natural wonders of British Columbia, Alaska, and Mexico most of her life and is eager to share her experiences. Self-educated in the natural sciences, Copper’s love of the outdoors dictates is mirrored in the vast range of subjects she finds fascinating, from the Sonora desert, to North American bears, and marine life to glaciology. A certified Master Gardener, Copper has published articles on botany and entomology for the Master Gardner Journal and the Roots & Shoots newsletter in her native Arizona. She has also lent her expertise as a volunteer at the Adobe Mountain Wildlife Rehabilitation Center, where she worked with injured raptors and other birds and animals. She also trained non-releasable birds of prey and other injured birds and animals for use in educational programs.

Copperis fascinated with Native culture and the diverse marine and plant life of Alaska. One of Copper’s favorite hobbies is photography - she often takes landscape photos and recreates them in watercolor. Other interests include gardening, camping, playing the piano, and reading. She is a passionate storyteller and interpreter and uses her talents in educating guests about the many places she travels.



David Miller
We were cruising through the Russian-owned Kuril Islands on a repositioning trip from Singapore to Alaska and made a stop at a recently abandoned submarine base on one of the wind-swept, volcanic islands. As we came ashore it quickly became apparent that we'd arrived at a modern-day ghost town. Old army vehicles lay rusting in the misty air. As we entered the buildings, it was as if the entire population had left with but a moment’s notice. In one of them – it must have been the military operations headquarters – the floor was piled knee-high with books, manuals and personnel photos. Wherever you looked, the red star of Russia offered the only splash of color in this mysterious, forgotten outpost.

Born and raised in Seattle, David attended the University of Washington, earning a Bachelor's degree in Forest Management and Environmental Science. After graduating, David worked as a forester in the Columbia River Gorge. He's worked as a driver and guide in Alaska’s Interior and Denali National Park and also aboard various cruise ships as a cruise director, lecturer and singer.

David has been with Cruise West since 1983, aboard the Spirit of Alaska , the Spirit of ’98 and the Spirit of Oceanus. As an Exploration Leader, he brings first-hand experience (and with that, countless stories!) from years spent backpacking the world, living and photographing native, indigenous cultures, teaching English in Thailand, sailing the Caribbean and facilitating sea turtle breeding and rehabilitation in Florida. His goal is to instill a passion for and appreciation of the natural world in the people around him. David now lives in Orlando, Florida, where he teaches 7th grade science.

James Shaw

James was born in Taiwan and raised in the suburbs of New York City. The outdoor and wilderness bug bit him when he joined Project WILD (Wilderness Initiatives and Learning at Duke) at Duke University. The initial outing, roughing it, camping, hiking, rock climbing, swimming, and other outdoor activities, in the Pisgah National Forest of western North Carolina instilled his deep appreciation for the great natural surroundings and beings of our world. Since then, James has eagerly pursued travel opportunities and adventures on the seas and in the wilderness, which have included sailing around the Bahamas, swimming with dolphins during a fishing trip near the Hawaiian island of Lanai, hiking the Grand Tetons and the coastal mountains of the Italian Riviera, climbing Black Tusk in British Columbia, traveling through Alaska and the Inside Passage, working as a tour guide in the Canadian Rockies, and much more.

After spending the past ten years in the corporate world as an attorney James zealously returns to the life of tour guiding and exploration with Cruise West. A resident of Seattle for over 14 years now, James moved here to live near the mountains and the waters of Puget Sound and the Pacific Northwest. James enjoys hiking, skiing, kayaking, boating, and all outdoor challenges. Besides the adventure and exploration, James loves to learn about cultural history and the natural world around us and looks forward to sharing his knowledge and experiences with the guests of Cruise West.




Jessica Rickard
As I snorkeled around the side of the ship I could see a group of a dozen guests surrounded by three playful bottlenose dolphins, two females and presumably one of their babies. The guests were amazed! I had my camera of course, safely in its underwater housing, so I swam up and began snapping away. Before I knew it, the baby dolphin took an interest in me. As I was free diving, it began mimicking my head-down position in the water and started picking up sticks and rubble from the bottom, as if showing off its toys. The guests couldn't believe their eyes – it was incredible!

Jessica has spent countless hours on the water as a researcher with the Marine Science Consortium’s Dolphin Research Project on dorsal fin identification of bottlenose dolphins. She's also done field research in the Galapagos Islands, the Florida Everglades and the Florida Keys. Jessica holds a Bachelor of Science in Biology and Marine Biology from Saint Francis University in Pennsylvania. Jessica's interest in marine science led her to the Catalina Island Marine Institute where she spent 2+ years as a marine science instructor and aquarist. She's also worked at the Marine Science Consortium in Virginia as a marine science instructor and Elderhostel assistant.

Jessica is a certified American Red Cross lifeguard and certified Divemaster, an avid knitter and artist. A passionate photographer, she watches diligently for glimpses of wildlife, and you'll rarely find her without a camera around her neck. Jessica harbors a boundless enthusiasm and deep love of learning and sharing information about the natural world. She looks forward to welcoming you aboard.



Kate Caldwell
Nature has a way of inspiring people all on its own, but it's the 'ah ha!' moments that I look forward to the most – the times when I'm interpreting a plant, or an animal, say – and the light bulb goes off and the guests say, 'I get it! … and then that moment is theirs.

Passionate about travel, adventure and nature, Kate has worked for The Nature Conservancy in Florida and Colorado for the past sixyears, where her responsibilities included facilitating community outreach programs, naturalist workshops, donor visits and ranch tours, coordinating with the Florida State Chapter Department and sitting on the board of the Colorado Field Institute. Prior to that, Kate spent 10 years as a Programs Coordinator at Walt Disney World in Orlando, Florida, where she managed youth and adult education programs and earned the Walt Disney World Partners in Excellence Lifetime Achievement Award and the Excellence in Training Award.

An animal lover at heart, Kate has volunteered for the Florida Turtle Conservation Trust and the Central Florida Zoological Park, where she facilitated learning and conservation efforts and assisted with mark/recapture and radio telemetry studies of Florida box turtles. Kate enjoys scuba diving, whitewater rafting, kayaking, camping, rock climbing and biking and is a horse trainer, riding instructor and downhill ski instructor. When she slows down, she enjoys a good book (especially if it's about nature), paints watercolor and studies interior design.



Kieron Weidner

I love to share my knowledge and thirst for adventure with any who are willing to take the road less traveled and gain inspiration from nature.”

As a young man Kieron was constantly in the outdoors. Twelve years in Boy Scouts and growing up on a farm in rural Wisconsin provided plenty of opportunities to explore all kinds of outdoor recreation. By the time he graduated high school he had logged hundreds of hours exploring nature; canoeing in Canada, hiking the Rocky Mountains, mountain biking, skiing, snowboarding, kayaking, rock climbing and just about anything else you can do outside.

Kieron earned a degree in Biology at the University of Wisconsin – Madison with coursework focused on Environmental Studies, Ecology and Conservation. During college he spent five months studying Tropical Ecology and traveling in Costa Rica and Panama. Upon graduation Kieron attended a UNESCO graduate program in Europe called Ecosystem Management in Cultural Landscapes – which explored how culture and politics affect natural resource management.

In his career Kieron has worked as a restoration ecologist with the BLM, National Park Service and Washington Department of Ecology. He has lived, worked and played in a full spectrum of environments from desert to rain forest. When he’s not working for Cruise West, Kieron resides in Seattle, Washington.

"The best part about my job is that each day holds the possibility of introducing our guests to a brand new experience. Whether we are encountering wildlife or seeing part of the landscape for the first time, that moment of discovery is always truly amazing."

Marcy has a love of the outdoors that developed since she was a child. Growing up in Michigan, her family spent summer vacations camping and enjoying long days at one of her home state's picturesque inland lakes. As she matured, Marcy's interest and appreciation for outdoor activities and learning about wildlife grew. She spent a couple of years working at a Colorado ski resort and for the past 12 years has been involved in the travel and tourism industry.

Marcyworked for a marine mammal rehabilitation hospital in Sausalito, California and was the Education Director at a small natural history museum in the San Juan Islands of Washington State.Marcy holds a Bachelors in Art from the University of North Florida which she completed in 1995.

Today, Marcy lives in Portland, Oregon with her husband and two cats. She spends her free time backpacking, car camping, snowboarding, bicycling, knitting, sewing, cooking, and frequenting any one of Portland's many brew-n-view movie theaters.



Meriwether Gill
We were in Endicott Arm Fjord when out of nowhere, a 'shooter' exploded in the foreground of Dawes Glacier. I'd never heard nor seen anything like it before … the thundering sound and the blue of the ice left our guests awe-inspired. The experience defined, in my mind, the true grandeur of Alaska.

Meriwether sharesher love for marine mammals and her background in cetology – the study of whales, dolphins and porpoises. Meriwether attended Hollins University in Roanoke, Virginia and double majored in Biology and Psychology. She's since earned a Master’s in Liberal Arts, with a focus in marine mammal behavior and training. While an undergraduate, Meriwether worked as a marine educator at Sea World of Florida. She's also interned at the Dolphin Research Center in Grassy Key, Florida, training dolphins and learning about dolphin therapy.

Part of Meriwether's past life was spent in Hawaii, where she worked as a naturalist for the non-profit Pacific Whale Foundation, educating guests on humpbacks, Hawaiian spinner dolphins and coral reefs. She also worked in the Foundation's research department, studying the function of the humpback whale’s song and the behavior patterns of Hawaiian spinner dolphins. Meriwether is involved in several conservation efforts and enjoysto educating Cruise West guests on current conservation and management issues as well as the latest research endeavors surrounding marine mammals. She recently completed a project with The Center for Whale Research in Friday Harbor, Washington, assisting Ken Balcomb and his team in keeping their photo-id catalog of resident orca pods up-to-date. Through this work, she's learned to recognize individual orcas by the shape of their dorsal fins and saddle patches.

When not cruising, Meriwether enjoys sailing, skiing and traveling, and has returned recently from travels in Patagonia, Iceland and the Galapagos Islands.

Something you might like to know about her?
Meriwether is a descendant of the Meriwether Lewis of Lewis and Clark. A possible source of her passion for exploration? We think so.



Paulino Perez
Paulino’s experiences have taken him from sailing small ships in the icy waters of Southeast Alaska to the protected areas of the beautiful islands in Mexico’s Gulf of California.

Paulino resides in La Paz, Mexico, with his wife and son. He has a degree in Marine Biology and an intimate knowledge of the flora and fauna that we will encounter on our voyages.

Taking a nature hike with Paulino will enlighten you to the fragile eco-system some of the places we visit. He will point out flora and fauna that most eyes simply pass over.

Teresa Mealy
I was taking a group kayaking in Glacier Bay when we spotted a pack of wolves (rarely seen in the park) on the shore across a small inlet. We paddled closer and as we approached, the wolves began to howl. There were 5 of them, all bellowing, noses pointing towards the sky … and I'm not quite sure why – but we joined in! Suddenly, there were 7 of us howling back and forth with the pack – it was as if we were exchanging conversations about our day.

Born and raised in Seattle, Washington, Teresa grew up exploring the woods and waters of the Pacific Northwest. From walking the shores of the Puget Sound to hiking the Siskiyous and kayaking the pristine waters of Glacier Bay, Teresa has experienced much of what the region has to offer.

Teresa graduated from the University of Portland where she majored in Environmental Ethics and Policy and minored in Environmental Science and Social Justice. Teresa spent three years volunteering as a naturalist for the Seattle Aquarium, where she educated visitors on the marine environment, interpreted exhibits and organized and facilitated the Marine Science Day Camp. Teresa has also spent two summers as a crew leader with the Northwest Youth Corp, a non-profit organization specializing in providing jobs integrated with environmental education to youth in the Pacific Northwest. Most recently, Teresa has worked as a teacher's assistant for a Marine Biology class at the University of Portland. Teresa is Red Cross certified in Wilderness First Aid and Small Craft Safety. She was a four-year member of the University of Portland Crew team and is an avid hiker, sea kayaker and rock climber.



Weston Eiler
"Standing next to guests who are totally new to Alaska, it's priceless to see the look on their faces when a whale breaches or when porpoise ride off the bow."

Born and raised in Juneau, Weston knows Alaska like the back of his hand. One of the things he loves most about it is the fact that even for someone growing up there, "there's always something new to see and experience."

Weston has spent several seasons leading tours for Cruise West and as a tour guide at the Alaska State Capitol Building. Currently a student at Willamette University in Oregon, he's pursuing a Bachelor's degree in Politics and Environmental Science. Weston's strong interest in Alaska’s unique political history has led him to volunteer at the annual Model United Nations conference at the U.N. in New York. He's also interned at the Oregon State Legislature and on Capitol Hill, and has done research on the politics and policy of Pacific fisheries management.

When not studying or guiding a Cruise West tour, Weston enjoys kayaking, running, soccer, reading and falconry.
