To determine the invasion threat to the NE Pacific of marine algae arriving on Japanese debris from the 2011 Great Tōhoku Earthquake and Tsunami, my colleagues and I took up the task of identifying the algal species on 42 of the most heavily fouled debris items that landed on the...
To determine the invasion threat to the NE Pacific of marine algae arriving on Japanese debris from the 2011 Great Tōhoku Earthquake and Tsunami, my colleagues and I identified the algal species on 42 of the most heavily fouled debris items that landed on the shores of Oregon and Washington...
This report is a brief overview of the status of Oregon’s oyster aquaculture in the mid to late 1970s, including discussions of trends in harvests and research into oyster breeding.
This report has three primary objectives; it attempts to examine the relationship of various cultural systems to the marine environment, seeks to create an inventory of uses man has put the marine environment to, and makes an analysis of the attitudes of people towards the marine environment.
An article detailing the intense storms on the Pacific Northwest coast in the last 10 days of October 1977. Reprinted from Mariners Weather Log 22 (2).
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.
This is a student report which studies the effects of wave action on intertidal zonation at Yaquina Head. It includes hand-drawn diagrams of quadrants sampled at the location.
This paper is record of early work in oyster culture in the west coast oyster industry. It summarizes operations for a year of running the OSU pilot oyster hatchery, and subsequent recommendations for its continued large-scale production of oysters.
A student report for a Civil Engineering 572 class, this document is an extensive description of the Salmon River estuary, including water flow, quality, predictions for the estuary’s future, and numerous charts and graphs.
Heceta Bank is a large reef on the edge of the central Oregon continental shelf that supports a wide variety of commercial fisheries. Using the research submersible Delta, we studied fish abundances on Heceta Bank and the relationship between species composition of fish assemblages and bottom types. Cluster analysis indicated...
Submersible belt-transect surveys along a rocky bottom were combined with acoustic surveys of the water column to estimate depth distribution and density of fishes at Stonewall Bank, Oregon in the northeastern Pacific Ocean from September through October 1991. The objectives of the study were to determine the proportion of fish...
Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
The management policy of the Fish Commission of Oregon concerning the Pacific pink shrimp, (Pandalus jordani) has resulted in regulations which apply to all shrimp along the Oregon coast and do not recognize separate populations. There are several shrimp grounds along the 300-mile length of the continental shelf off Oregon...
As a prelude to tagging studies on pink shrimp (Pandalus jordani) or other laboratory studies, basic information was needed to establish criteria necessary to hold shrimp in aquariums with minimum mortality. A one-year study was conducted at the Fish Commission Laboratory in Newport to obtain data on these requirements. The...
