: Due to COVID-19, Intersea Foundation will not be conducting voyages until further notice. Here is some general information about past and future expeditions.

Humpback Whale ALASKA, with its abundant wildlife, temperate rainforests, and glaciated fjords, has become one of the last places on earth left virtually untouched by man. A visit to this pristine wilderness is more of a journey on a path of discovery than a trip to the higher latitudes. Many who visit return again, often repeatedly, to explore with greater intimacy.

The Intersea Foundation has been conducting expeditions in this remote wilderness for over two decades, making us one of the oldest expeditioners in Southeast Alaska. Our voyages are for those who wish to explore Alaska on a more intimate level than can be afforded by a larger group, and for those who would like to learn more about the humpback whale -- actually participating in our long-term research effort.


The Alexander Archipelago of Southeast Alaska is summer home to feeding humpback whales -- the largest aggregation of humpbacks in the North Pacific. In these inside waters, 100 miles from the nearest ocean swell, the humpback feeds almost continuously on the rich proliferation of life, produced by the long daylight hours and the cold Alaskan waters. Other animals share the bounty...the orca, minke whale, Dall's porpoise and harbor porpoise, and the birds. The red-necked phalarope flitters from bubble-net to bubble-net created by the humpback, to benefit from the krill-laden upwelling. Bald eagles soar overhead and flank the shores to feed off salmon returning to where they were spawned. Steller sea lions intersperse their lounging about the islands with pursuit of prey, and sometimes playfully or aggressively interact with other marine mammals, particularly the humpbacks.


Our objective is to continue our long-term studies on the feeding ecology of humpback whales, specifically cooperative feeding whales. This is a behavior which we were the first to document, and which has continued to be the focus of our studies. We will photo-document individuals and behaviors and record the summer songs for comparisons with other feeding groups and other years. Our studies have been featured in numerous film productions including National Geographic, NBC, ABC, the Discovery Channel and in the IMAX film ALASKA - SPIRIT OF THE WILD.


Alaska is a wonderful land of unspoiled beauty. To have a safe and fulfilling voyage, it is essential that travel occur with experienced operators. Our vessel is operated by a Captain with a 1600-ton USCG masterís license, indicating exceptional sea time experience. We are able to visit pristine land sights that are inaccessible to others, because these lands are privately held, protecting them from the potential of logging. And the whales, with their specific patterns of behavior and areas of travel, are well known to the staff, and most are literally on a first name basis. These are just a few of the considerations that will determine the quality of your trip.

For more information please contact us.

Thank you.
