This document contains transcripts of Joel Hedgpeth’s series of lectures delivered over KPFA radio in Berkeley, California. These passionate lectures described the uses of oceanography, attempted to differentiate between oceanography and marine science, and encouraged students to pursue oceanography. Joel Hedgpeth was a director of the Hatfield Marine Science Center.
Wave energy research and development has been ongoing in Oregon for at least two decades. Substantial interest started in the early 2000’s, flattened in the 2010’s, and is on the rise again. The Oregon wave energy sector recently experienced several sizable developments in 2020 and 2021, making this a critical...

The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...

"The Pacific Northwest Seafood Association is involved in several activities. Our primary goals are to maintain the greatest long-term, sustainable harvest utilization and value-added benefits from all of our fisheries. In 1992, the state decided that commercial fisheries should be designated a key Oregon industry. That event combined with several...

Even after 140 years without a fire, mixed-conifer forest such as Teakettle’s Experimental Forest has a
distinct patch pattern and complex structure. Researcher Malcolm North and colleagues examined the
structure and function of these ecosystems and their response to widely used restoration treatments.
Collectively the studies found fire was essential...
Detailed analysis of mixed-conifer and red fir forests were made from extensive, large vegetation sampling, systematically conducted throughout the Teakettle Experimental Forest. Mixed conifer is characterized by distinct patch conditions of closed-canopy tree clusters, persistent gaps and shrub thickets. This heterogeneous spatial structure provides contrasting microclimate, habitat and resource conditions...

Climate warming may first show up in forests as increased growth, which occurs as warmer temperatures, increased carbon dioxide, and more precipitation encourage higher rates of photosynthesis. The second way that climate change may show up in forests is through changes in disturbance regimes—the long-term patterns of fire, drought, insects,...

The ponderosa pine ecosystem of the West have changed dramatically since Euro-American settlement 140 years ago due to past land uses and the curtailment of natural fire. Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increased from a grange of 49-124 trees per ha (20-50...
