Jon M. Erlandson

• 1. Santa Barbara Surfing Origins

  ›

  Jon M. Erlandson grew up in Santa Barbara, California, where he spent his childhood swimming, surfing, and sailing on the Pacific Ocean. This early immersion in water-based activities shaped his lifelong focus on coastal environments. He earned a Bachelor of Arts degree in Physical Anthropology from the University of California, Santa Barbara in 1980. His academic path continued at the same institution, where he completed both a Master of Arts and a Doctorate in Archaeology. By 1982, Erlandson had moved to Alaska, beginning a career that would take him across Washington, Oregon, and eventually back to California upon retirement in 2023.

• 2. Maritime Adaptations Theory Shift

  ›

  For decades, anthropological theories held that access to marine resources developed late in human history, roughly within the last 10,000 years. Jon Erlandson challenged this view by pointing out that hunter-gatherer societies using aquatic resources were among the most complex and supported higher populations than their terrestrial counterparts. Shell middens found in Africa and Europe date back at least 150,000 years, providing evidence for much earlier maritime adaptations. One of the earliest archaeological sites in the New World, Monte Verde 2 in Chile, contained several types of seaweed, further supporting the antiquity of these cultures. Despite challenges like rising sea levels and erosion, Erlandson argued that submerged coastal sites on continental shelves hold vast untold stories about early human life.

• 3. Kelp Highway Migration Route

  ›

  In collaboration with colleagues including Todd J. Braje, Erlandson developed the kelp highway hypothesis to explain how people first populated the Americas. This theory suggests a coastal migration route followed productive kelp forests stretching from northeast Asia down to Baja California. These kelp forests provided abundant resources such as fish, shellfish, and sea mammals while offering protection from harsh open-sea wave conditions. The hypothesis helps account for pre-Clovis sites like Oregon's Paisley Caves and Monte Verde, which date to approximately 14,000 years ago before an ice-free corridor opened. Although difficult to evaluate due to post-glacial sea level rises, extensive evidence supports early maritime activity along the Pacific Coast of the Americas.

• 4. Channel Islands Human History

  ›

  The Channel Islands off the California coast have been inhabited by humans for more than 13,000 years, offering unique insights into long-term coastal adaptations. From at least 9500 years ago until their removal around AD 1820, these islands were home to the Chumash people. Erlandson and his team studied the diet and subsistence strategies of the Island Chumash to understand how they influenced marine and terrestrial ecosystems over millennia. Their research reconstructed how ancient communities survived on small islands despite environmental changes. A key study published in Pacific Science examined 12,000 years of maritime subsistence and adaptive adjustments on California’s Channel Islands, revealing deep historical connections between human behavior and ecological shifts.

• 5. Icelandic Viking Age Excavations

  ›

  In the Mosfell Valley of Iceland, Erlandson led interdisciplinary fieldwork spanning seven seasons with colleagues including Jesse Byock and Philip Walker. They excavated three sites occupied during the Viking Age from the early 10th to mid-12th century. These locations included a well-preserved early Christian church graveyard, a large Viking longhouse, and a ritual cremation feature atop a knoll shaped like a ship's prow. The archaeological evidence correlated with written sagas, showing movements of bodies from pagan burials to new Christian graveyards and instances of violence tied to blood feuds. Notably, researchers discovered the first archaeological evidence for cremation in Iceland, resolving prior debates about initial settlers who lacked such mortuary records elsewhere in the Viking world.

• 6. Conservation Policy And Ecosystem Collapse

  ›

  Following the Exxon Valdez oil spill in 1989-90, Erlandson worked to protect archaeological sites while teaching at the University of Alaska Fairbanks. His collaboration with marine biologists inspired involvement in conservation policy regarding endangered coastal fisheries and ecosystems. A paper titled Historical Overfishing and the Recent Collapse of Coastal Ecosystems by Jeremy Jackson et al., which Erlandson contributed to, was named Discover Magazine’s top science story of 2001. This work linked ancient shellfish consumption patterns to modern ecosystem collapse, highlighting how human impacts on marine environments have persisted over thousands of years. Erlandson has since received multiple awards for outstanding teaching, research, and mentoring minority students, reinforcing his commitment to both academic excellence and environmental stewardship.
